I axed my Twitter profile, and I don't regret it. Originally I got it for professional development, but later realized that that is pretty silly, ultimately.

I'm happier when staying in reality, even if I amass less Internet Points in the meantime. Nothing really happens on Twitter, people just react endlessly to things. Plus, after having a kid, I find it hard to care about dumb adult stuff like 'professional influence' on social networks. If I want to get my ideas out, writing a blog post and working on projects that further those ideas is far more influential than Twitter ranting.

This is my own experience, I don't expect that it'd apply to everyone, but I found value in leaving.
False positives and false negatives are both really bad. Now if there’s an ICBM launched at Hawaii this weekend, no one will believe it.
I would think the actual care would be the highest priority for most people. These companies are so closely watched that billing disputes are extremely rare.
Several things... for example: as a seller advertising on Amazon, you are sharing all your profit metrics with a potential competitor who has a history of stepping in with their own proprietary branded products where they see significant profits to be made.
They can't though for compliance reasons, that's why they invented Tether.
I really like the doctors at Kaiser. All very smart and caring. But their billing department is awful. I paid my bill every month but still got sent to collections multiple times. They would always recall it, but it was a giant pain in the ass.
Ok, but in this case the contractor should make at least 2x as much the in-house staff, considering they're bringing all their own tools, paying for their own health insurance, paying their own taxes, and having a more flexible schedule.

And then there's the question of why hire a contractor in the first place if you already have a strong team of devs — why not just hire another full-timer? Most likely you're having trouble filling out your team or filling a crucial role. That would probably be worth a little extra to you.

Plus, there are tons of companies out there who don't need a full dev team of a dozen people, but know they could benefit a lot from hiring contractors for 3 months at a time for one-off projects. These companies are more than willing to pay a little extra to get a job done well on short notice.
It'd be neat if Twitter started not displaying the vanity metrics for awhile just to mess with people.
OP here:

I created this tool because on the last few teams I've worked on, pull requests would linger around and start then start to get backed up. It's not fun for managers to chase after old PRs or for developers to constantly beg each other for code reviews.

I'm hoping that this tool can help teams stay on top of their pull requests without as much manual nagging!
You're looking at top-line cost to provide care in a very convoluted market. Take chronic for example, a huge chunk is spent on drug treatment. Incentives to use generics are often misaligned from the needs of the patient.

Also, about 10-15% of the $3 trillion is administrative waste (payers). There are a lot of areas that we can save.
In retrospect, I've wondered if Dr. Sbaitso actually wiped the memory afterward, or just said it would as a joke.
I've had great luck with just using whatever specialist is in network by default, and just calling or emailing my old doctor for a second opinion if something weird happens. I assume not all doctors are so communicative, but I think many are happy to help as long as it doesn't take much time.
Subpeana everything. The government has a lot of power and a long arm, and a few centuries of experience hunting down money trails.

You are talking about the math, and I'm talking about what happens physically. As an analogy, this is like talking about whether F=G * m1 * m2 / r^2 is an accurate mathematical model of gravity in the weak limit (it is) vs talking about whether earth is actually pulling you down towards its surface (it isn't).

But since you are obviously well versed in the math, I suggest you read the Cerf and Adami paper that my presentation is based on: https://arxiv.org/abs/quant-ph/9605002 Also, Zurek's work on decoherence. Those will probably answer your questions better than I can. I'm just a popularizer, not a physicist.
I've long wondered how we've allowed insurance companies to operate as public, for-profit entities—it's a complete conflict of interests.

Yes, of course. I meant to convey that for the providers that can't refuse, like hospitals or ambulances, sticker prices not realistic because the provider is having to gamble on which portion of the people they treat can and cannot pay, and how much, so they inflate their prices extremely high. And also to negotiate with insurers.

"structural engineers built the suspension bridge" is a false statement though. Engineers don't build generally, they engineer.
So, here's a thought experiment: consider "Carl H". Carl H ran the site computerscienceforeveryone.com. He was an incredibly passionate individual who spent his time creating free video tutorials on C programming. Along with these videos, he created supplementary materials, quizzes, and engaged with anyone who had questions. He even provided live one-on-one instruction to people over Skype, all for free. By all accounts, he was an excellent Computer Science teacher.

Carl was arrested for molesting his nine year-old son. He committed suicide in jail awaiting trial.

With that said, do we disregard all of the learning materials he created? Is their value inherently reduced to zero now that we know they were the product of a sick individual?

This isn't just an thought exercise. Carl was a real person. He had a Reddit board dedicated to his lessons and instructing people. His website has since lost its host and pretty much all the videos are gone from the web, save for p2p torrenting, because no one will be caught dead hosting videos from a child molestor, not matter how innocuous the videos themselves were.

If you want to do absolutely everything yourself from DNA extraction to sequencing and data analysis, then yes, this is probably the cheapest way.

But you also need to consider how you prepare your DNA to go into the Nanopore. It's a lot more investment than you might think. Extracting your DNA in a clean enough way for it to work with the Nanopore will require equipment/facilities that most people will not have access to (phenol/chloroform is the optimal way to extract DNA, which will require a fume hood and toxic chemical disposal). Depending on how you want to prep your DNA, you might need more specialized equipment/reagents (Ampure beads, ligation kits, end-prep/TA-tailing, etc).
Oh yes the SEC can absolutely claw back by applying laws in retrospective. Having too many offenders was never a problem for SEC.

Not only that, but once they realized the message was sent in error they didn't have a simple way to correct course so there was a big delay between the realization and informing the terrified public.

One counterpoint is that some therapeutic traditions have suggested a potential benefit from "autoanalysis", which is a form of structured solo psychotherapy. In that framework, the bot could be seen as helping people to perform autoanalysis. (I'm not sure of how much esteem this method is held in by mental health professionals today.)
It’s more than that though. There are countless improvements, but the option of a more ribbon-like interface is more polished than its ever been, and in many ways more usable than the Office Ribbon. And I do emphasise that’s an option - we retain the old UI and will always do so for users. We haven’t forced a radical change on them because we actually value our power users.

Aside from way better compatibility improvements with Office interfaces, there are stability fixes, we’ve done extensive document fuzzing, improvements to mail merge, updated our table styles, a huge improvement to our grammar checker, way better OpenPGP integration, a complete rewrite of the EMF+ filters (that has been a huge effort, and a much bigger impact in handling Office docs than you might realise)... the list is huge!

This is actually not true. Library circulation systems actively work to purge themselves of historical transactions, at least, the few I've worked with. If anything they keep the "last patron" for a given item for some time, in case damage is reported, but beyond that there is no historical record, to eliminate the possibility of searching that data via warrant or otherwise.
Or, there were a bunch of potential land-mines set in this process, and eventually the employee stepped on one. Which one he stepped on is maybe less interesting to me, than the fact of the organizational culture producing multiple ones to step on.
I think we're on the same page. I was simply highlighting things I witnessed from my past experience. Bugs (in Mac OS) get really nasty sometimes and frustrating for the most part. It is brain consuming and the reward isn't always worth the energy spent. Management doesn't even reward bug fixing unlike the "new" stuff. Ask any dev from that specific team (or even iOS team) to fix bugs for a whole year and you'll see the reaction. Some actually do because of a "lower" global performance at work. You can easily get assigned on bugs over "new" stuff if you don't hustle 24/7 but that's a whole new topic :)

But to add up to my previous comment - only a few people get to implement new stuff each year, they don't test their code and fall under very tight deadlines, so they produce buggy stuff. This generates tones of new bugs constantly tracked by QA (QA doesn't fix anything, they just report problems), bugs quickly pill-up in Radar and developers are already assigned onto something else. Most of the bugs reported by customers are duplicates... they're usually already tracked, either not assigned yet or simply lower priority than something else. So what it the problem? Well, everything I mentioned ;)
I'm not saying the UI of their system is great, since I have never seen it, but I believe it's a better idea to have the "test" alert be very similar to the real one. When the time comes to send a real alert, the operators should be practiced. Diverging the UI could cause confusion in am actual emergency, wasting precious moments.
So I agree that there's been a move away from "low seretonin == depression" and the model that depression is due to low seretonin (if it was even in favour), is giving way to "it's much more complex. We don't understand too well". [1]

And, there is an argument that is made that such drugs aren't effective anyway (or no more than placebo).

However, I think that's an over simplification [2]. And I don't necessarily accept the contention that SSRIs / SNRIs and others just treat symptoms.

This goes back to what I was saying earlier, that what works for person X may not work for person Y, not because the treatment isn't effective by itself, but because the etiologies may be different. All the way from a single SNP (single nucleotide polymorphism)) introducing a subtle amino acid substitution in a receptor on the cell surface to the cause being due to a vitamin deficiency (B-complex, for instance, or vit D, as another comment mentioned, or low Mg levels!) to psychological trauma. There are so many reasons that can lead to depression & anxiety.

It's like fever. Some fevers can be treated with Tylenol. Others will need quinine, and Tylenol in such a case would be ineffective.

What it also means is that we need to find better therapeutic targets in addition to seretonin / dopamine receptors, etc., and maybe move to a combinatorial drug approach once the targets are identified & validated. (like is used in oncology).

So please do not dismiss drugs. Or therapy. Or CBT. Or lifestyle changes (diet, exercise). Environmental changes (job, social circle). It could be any of these that can help someone deal with, navigate through and resolve depression. And it can be frustrating to try and narrow down among these. But that's the nature of the beast :/.

Personally, I've always wondered why we blithely accept having incredibly expensive shit services and coverage dictated to us.
I read Pilecki's book (aThe Auschwitz Volunteer: Beyond Bravery) and found it incredible. And I too was amazed to read in the introduction that during Pileki's detainment by the communist regime, he told one of his friends that, compared to what he was ensuring in that prison, Auschwitz was "like a kindergarden".
Maybe I'm biased, but personally, I never ever clicked on any ads showed up along my google search query, even if they are relevant. I just can't get rid of the nagging feeling that: "there gotta be better deals else where (e.g. on Amazon?)" or "The merchant paid Google a premium to show up along side my search results, the price can't possibly be the lowest". Am I the only one feeling this way?
Well, LQR is a linear control law. It's in the name: Linear Quadratic Regulator.

But as noted in my comment above, linear controllers can be used to control nonlinear systems under certain circumstances.

p.s. btw, having more states in the model does not linearize a nonlinear system per se. Only nonlinear transformations like log-transforms are capable of linearizing a system.
> People don't pay individually for private security/police. We don't pay for fire.

Sure they do. Rich people hire private security all the time. Heck, not-rich people do it too. Like your local Chuck E Cheese who hires a security guard on Friday night.

Same with fire protection. There are plenty of private fire protection companies.

Everyone gets those basic services paid for out of their taxes, but some people want more than basic service, and there is nothing wrong with that.

The OPs system would work great and you could modify it simply enough to account for your system too -- everyone pays a health tax, which is then redistributed as an HSA payment to every American, setting a base level of funding.

I'm actually a big fan of single payer, but not because of the social impacts, only because of the ease of administration aspects. But if you did OPs system and made sure everyone could participate, it would probably work just as well, because there would need to basically be a health payment cleaning house to make it work.
You are on the right path. Quant is a bit of a catch all term for risk/traders/developers that work with financial instruments. Learn about different financial products and the different quant positions. Understand that Quants at IBanks and Quants at hedge funds do drastically different things (as an IBank quant myself - you don't want this job). And even those at hedge funds vary based on the instruments they trade in and how the firm operates (quant vs fundamental). Many quants are simply risk analysts. The quant positions that make the most money are typically quant traders or PM's that run a quant/hft book (see Jane Street/Two Sigma etc). Those positions definitely require a PhD or masters in applied math/physics/comp sci.

I would recommend talking to recruiters (try contacting GQR) about positions in the field.

Just going to throw my 2-cents in - I should note that my knowledge of PID is very limited.

The first time I encountered an explanation of how PID worked that made sense to me, was via the Udacity CS373 course that I took in 2012 (Thrun also had a great explanation on how a Kalman filter worked as well). This explanation of PID was repeated when I took the Udacity Self-Driving Car Engineer Nanodegree (starting in 2016).

In the CS373 course, Thrun detailed a few different ways to tune a PID controller - but one way he covered was rather curious in how it worked. It wasn't perfect, but it got you "close enough". I'm not sure if it would work well for a "real system" but for the purpose of learning it seemed to work well enough.

He called it "twiddle" - I don't know if he was the original author of it, or what - but here's a video that describes how it is implemented and how it works:

https://www.youtube.com/watch?v=2uQ2BSzDvXs

It's actually pretty neat - and the concept can be applied to virtually any algorithm in which you are trying to minimize an error amount.

No one? My collection from friends in Hawaii is they’re more prepared. Each of them have at least contemplated a plan and a few assembled go bags. In any case, Japan and Korea’s experiences with false alarms don’t support your claim that a few false negatives outweigh a single false negative.

To be clear, I’m not saying false positives are okay. No error is better than error. But if we’re going to have errors, and we are, one kind is better than the other.
