When we have an opt-in healthcare system, people who are in perfectly good health will opt into favorable plans only they qualify for. Those born with expensive conditions or who develop a chronic illness won't be able to opt in, and will find themselves in a high risk pool paying hardship-tier premiums.

You write as if Srinivasan is being considered to run HHS/Obamacare. He's not. The FDA has nothing to do with health insurance.

When we have pharmaceutical companies opting into less stringent regulatory structures, even the most dangerous drugs will make it to clinical trials - to be tested by people who lack the ability to choose any other way of making a living.

I get the impression you want to remove this option from people, thereby giving them exactly zero ways to make a living. Is that correct?

Pharma manufacturers will then base their prices on what they believe the highest tier of wealth will bear, ignoring the long tail of underinsured Americans.

You seem very confused. The FDA does not currently regulate prices. However, FDA regulations do drive prices up and create a lot of monopolies in the pharmaceutical space.

If you want to learn what Srinivasan might actually mean for the FDA, I strongly recommend reading this blog post (written by a Trump hater, FYI): http://slatestarcodex.com/2017/01/18/watch-new-health-picks/
Technology is allowing anyone to have a voice. This is a good thing. Whether you are a human rights advocate or the biggest racist, you can now air your thoughts and gather a following. Each of us are becoming a political party of 1.

Think of the alternative; North Korea, where the information received by the masses is controlled by the State. Their lives are no better than un-thinking robots while the leaders live in absolute luxury.

Of course there are dangers in giving each one the power to affect other lives, and if it turns out that that power causes irreparatable segregation then it was a fait de complet anyway. I mean, the ultimate form of democracy is for everyone to have a voice, and if we are doomed because of it, then it shows a fatal flaw in the human species.

It's interesting that he includes an STM32, an FPGA, and other such devices, as support and peripheral emulation chips, in his effort to get his 6502 running as he would like.

Part of the education of my students here on the reservation we don't have a lot of resources. But we were able to score some nice FPGAs so they've designed and built from the gate level their own CPUs from scratch, then built compilers and interpreters on top of that. The youngest to do so was 9. It's been really convenient as well to be able to order inexpensive boards rather than having to deal with all the copper etching with chemicals as we did a few years ago.
Being an HR professional I would never ask for pay stubs to confirm someone's wages. What you are being paid is really non of there business. I always ensure that our Total compensation model is comparable to the industry and will work with the candidate to get them something we both can agree on.

I don't want to dis shaders on shadertoy, they are amazing toys (which is why it's called shadertoy). And, that shader you linked to is amazing as well. But, for example on my 2015 MBP it runs at 8fps in a tiny sub portion of a window. If I go fullscreen in runs in 0.3fps. Yet this same machine can run The Witness at 60fps or GTA5 at 30fps and see the entire world.

My point is the shaders on shadertoy are exercises in doing something for fun with limits (one shader and a few inputs) and not about speed or optimization or the anything to do with the way any game engine would go about to get performance.
No. Not true at all. At around a billion records, you start getting into distributed/scale-out systems, and distributed indexes are performance death whether for OLTP or analytics. Even before you cross into distributed query processing, the random access nature of indexes levies a heavy tax. Indexes are a tiny piece of this issue. They address the problem of finding a single needle in a haystack, but if you need to aggregate lots of data, indexes are largely worthless.

What about different compression schemes for different sets of "column" values - with the idea that you execute against the compressed values, rarely ever decompressing. Even column store systems that allow you to specify a compression scheme aren't adaptive. Why the hell not? This is almost 2020.

In my experience with researching online drug and exploit markets as soon as a reliable Tor-hosted email provider springs up they become the default email provider for almost everybody.

Previously the default provider has been safe-mail.net but they've had a lot of issues. Before that it was TorMail, and the FBI ended up seizing all of those mailboxes since it was hosted at Freedom Hosting (and was an amateur operation) [1]

What it means is that web email providers act more like online dead drops rather than as traditional email providers. PGP use is pretty consistent in these communities - as is rotating keys and email accounts.

[1] I can't recall of the top of my head any indictements that resulted from TorMail being seized.

What has changed is social media. Where people used to sit in front of their TV and fed their daily dose of what they believe after an exhausting day at work they no longer do that. Instead they are plugged into their phones all waking hours where people like them are reinforcing their beliefs. So they come to believe that their opinions are not as out there. They feel less aliened and more empowered. So they think they can voice themselves how they want. And for blue collar workers, that has meant that they have taken over politics. And the elite don't know how to stop them. How to control and socially engineer social media. This was not possible without the Internet.

I think the first person to put the idea forward was I. J. Good in 1962. He speculated that someday AIs would be good enough to do AI research better than their human masters. Then they would start making even better AIs. Which would make even better AIs, and so on. Leading to what he called an "intelligence explosion". He thought it would be "the last invention that man need ever make."

Bad "architecture smell", generally (except for niche cases).

Basically you don't want to rely on something that (1) requires a whole new service / monitoring later, (2) intrinsically exposes your data to untrusted sources and (3) can of course go "poof!" at any time -- unless you absolutely have to, or it's for something mostly ancillary to business and your data pipeline. (Or you're fairly small and just don't have a lot of people).

Especially when it's just CSV parsing, after all.
Tesla was growing rapidly in that era, and the sensors weren't even available at the start of calendar year 2013. All cars shipped with sensors starting in October 2014. It'd be nice if the NHTSA report quantified this a bit, but they didn't. I don't think your suspicion is correct: some of the AEB benefit is in the earlier figure, and the number of airbag deployments is not small.

Well, at some point the local system will run out of unclaimed matter and energy (Dyson swarm consuming all output of the local sun, built using all available matter in the system). So if you want to expand, you will have to leave.

There would also be some astronomical phenomenon that aren't easily reproducible locally, so it might be useful to travel to them instead.
These comments generally read to me along the lines of:

"It's totally reasonable to roll your own cryptography, as long as you're an expert in the field and do it correctly".

The rules of "Don't Stop And Peek" is general advice that is given out because the vast majority of people that conduct these kinds of trials are not statisticians, and will not do the math. Those that attempt the math will likely do the math wrong.

So, you're totally correct that if you know exactly what you're doing as a statistician and apply the math correctly, it can be possible to peek at results while still drawing a conclusion. This ignores the fact that, for most humans who are receiving the advice, this is terrible advice.

So, general rule: "Don't Stop and Peek". Advanced rule: "Unless you are a trained statistician, Don't Stop and Peek".

> Essentially the result of these design decisions in series is that if you install & use Discord, and fail to manually disconnect from your voice channel, next time you start your computer Discord will automatically join your last channel and broadcast any loud enough audio in the same room as your computer to the voice channel.

It's worth noting that Discord no longer does this if you've been away from the voice channel for more than 5 minutes. The feature was intended to autoreconnect you when the app was restarted due to updates and such, not to cause people to accidentally broadcast themselves on system start.
I picked it up just reading various C stuff on the internet - I think this one actually came from a Reddit user. It's not a use-case I think I've ever seen used anywhere, except for my personal code.

HFT is quite rarely about arbitrage, in fact (at least not directly).

I don't do arbitrage (there are easier ways that I hadn't fully exhausted yet), but between e.g. OKCoin and GDAX 30-second delays are common every day.

Hey! IPFS Dev here.

The cid stuff has been implemented and initial support for it is being landed in our 0.4.5 release (which will be soon, hopefully release candidate within a week).

With that and IPLD, you can craft arbitrary objects in JSON or CBOR (theres a 1 to 1 mapping, objects are stored as cbor) and work with them in ipfs. For example, i could make an object that looks like:

{
"Contents": {"/":"QmHashOfPkgContents"},
"Compression": "bzip2",
"NarSize": 12345,
"References": {
"foo": {"/": "QmHashOfFoo"},
"bar": {"/": "QmHashOfBar"}
},
"Signature": "signature info, or a link to the signature",
}

(please excuse my attempt at recreating a nar file in rough json).

This object could then be put into ipfs with:

cat thing.json | ipfs dag put

And you would get an ipld object that you can move around in ipfs, and do fun things like:

ipfs get <thatobjhash>/Contents

to download the package contents, or:

ipfs get <thatobjhash>/References/foo

to get the referenced package (or open that hash/path in an ipfs gateway to browse the package graph for free in your browser :) )

Everyone around him, his kids, his biographers, his employees, all say this is who he really is. So he's obviously aware of the image he's projecting, but I don't think he's self-aware in the way that comment implied, which was that he's just playing a character, and he's certainly never shown any evidence of humility.

Uber isn't an on demand ride service. They're a logistics company. Also uber isn't waiting for autonomous vehicles to come along and save them, they're one of the industry leaders in developing autonomous systems, investing/acquiring autonomous systems, and collect more driver/vehicle data than any other company in the world. It's not just civilian transportation either. They've already launched an autonomous commercial shipping service. If there is an item, person, or service that could potentially need to be transported from point A to B, it's a safe to assume that Uber has already started collecting logistics data on it and will(or already has) raise funds to begin implementing a network to service said logistical situation. This all may sound a bit extreme at first glance, but look at amazon. Amazon isn't a revolutionary e-commerce market place, they're a revolutionary logistics company. It's the same story as uber just in a different phase. Years of massive losses and outside funding. Both companies fully understand the value/defensibility of heavily investing in operational logistics at massive scale.

I, personally, would not.

And honestly, when I think back to the best leaders I have worked with they didn't necessarily have an enormous focus on the sort of individual development that you talk about. They were focused on the mission. To the extent that individual development furthered the mission it was vital, but the mission was always #1.

Having the clarity of thought to recognize this was clearly helpful to them.

> It's still quite hard to optimize queries especially if there are numerous JOINs involved

Sigh. In the real world (meaning 99+% of applications) there are a few big sets of data and lots of smaller sets of reference data. The thing that matters for performance is reducing that cardinality of the big stuff as quickly as possible. Which is a huge constraint on the search space.

Sure, in some theoretical sense, join ordering needs an A* algorithm or simulated annealing or some other esoteric approach to search. But in practical sense, it is almost a non-issue.

And here's the thing. Those systems with advanced search and costing for join ordering STILL make incredibly stupid decisions more than 3% of the time. And a bad decision can take hours to days and dominate all the good decisions.

DeWitt made incredible contributions to database architectures. He's a great guy and I'm a huge fan. But that was 30 years ago. Where are today's DeWitts?
> Tesla was growing rapidly in that era, and the sensors weren't even available at the start of calendar year 2013. All cars shipped with sensors starting in October 2014.

I don't follow the statement about sensor availability. That doesn't seem to change the fact that all the miles driven "after Autosteer" benefited from AEB, while at most a small fraction of the miles driven "before Autosteer" would have had AEB available.

Given that we know AEB systems do reduce frontal collision rates by 40% for all cars, as the NHTSA report stresses, that implies we cannot attribute the reduction in crashes "after Autosteer" to Autosteer alone.

(Which matters because articles such as the one posted are claiming a cause-and-effect relationship between the introduction of Tesla Autopilot and a reduction in crashes, but if a significant portion or even all of the reduction is due to AEB systems that other cars have also started to adopt then we're mistaking correlation for cause.)
