pdx··on Vitamin D Insufficiency is Prevalent in Severe Covid-19

    20 Patients in Study with COV19
      * 65% of them went to ICU (13 patients)
      * 35% of them did not (7 patients)

    Of the 13 Patients in the ICU 84.6% (11 patients) had VDI
    Of the 7 Patients not in ICU 57.4% (4 Patients) had VDI
Thin gruel indeed. But all they are saying is that it's perhaps worth doing a real study. That's fair.

Regulation often leads to regulatory walls around businesses, protecting them from competing with innovative new solutions, leading to lower quality of life for all. How does your worldview discount for this?

Yes, but the poster loves his dog more than any human has ever loved their child. He does not merely conform to societal norms with such love.
pdx··on Show HN: Oathkeeper – Cloud-Native Identity and Access Proxy

    ? you will agree.
Are they more extreme than nearly all other non-white people as well? Or just more extreme than white people? ;-)

For non-americans, the idea of a group of people who do not instantly submit to individual figures in authority, but instead, resist those in authority if they believe that those in authority are infringing on rights that are protected by the constitution, may seem really bizarre.

To condemn an organization because their raison d'etre is such resistance, would be normal in other countries, but it's a little frightening how a quick google search shows that condemnation here in America (assuming the people who wrote those pages were American).

I know a lot of HN readers are not American, so just wanted to clarify that we do have a slightly less submissive culture over here.

pdx··on Protocol for Asynchronous, Reliable, Secure and Efficient Consensus [pdf]
Yes, I believe that there is a non-zero probability that could happen, just as there is a non-zero probability that all the air molecules in the room you are in, which are bouncing around randomly, may all end up in the other corner of the room and suffocate you.

Since all nodes change sections randomly, like air molecules, they should remain randomly distributed, provided the network size is large enough. For a small network though, one can imagine you could get lucky eventually. Like other decentralized networks, security and size are related.

pdx··on Protocol for Asynchronous, Reliable, Secure and Efficient Consensus [pdf]
For SAFE Network, this is handled, I believe. Other networks that implement PARSEC will need to address it in some similar way.

In the case of SAFE, you can generate as many nodes as you want, but they must be valid nodes (doing the work that the network asks of them) for a long time before being promoted to a status that allows them to participate in consensus of a section. Any misbehavior on their part results in demotion or failure to be promoted. So each node would need to be a legitimate contributor to the network, with all that that entails, before being promoted to a status where their later misbehavior would matter. You would be creating real nodes, that used real bandwidth and real CPU resources and did real work that benefits the network, in order to infiltrate your evil nodes into the network. So, not an insubstantial cost to you.

Your nodes will be assigned into sections randomly, so it will be very difficult for you to manage to get multiple nodes with voting status, into a single section, and staggeringly difficult to get enough such that your nodes constitute 1/3rd of that section. Of course, exactly how difficult depends on network size (number of sections).

Finally, even once a node is assigned into a particular section, it will be reassigned to another random section at some interval, further decreasing your ability to take over a particular section.

pdx··on Sinclair Made Dozens of Local News Anchors Recite the Same Script
Except they're not "mouth pieces". Local journalists are much more independent than national ones. This instance by Sinclair of attempting to combat the national news broadcasters was a David vs Goliath attempt, and they are coming out of it much worse than David did.
pdx··on Dropbox Amendment to Form S-1
Dropbox is ycombinator alum. A ycombinator alum doing an IPO is worth bragging about on the front page.
pdx··on Show HN: MyCryptoWiki – A free cryptocurrency coin wiki
This is a common question. I suggest you think of it like stocks on the NYSE or NASDAQ. Does every IPO decrease the value of the already listed companies? Just as Comcast and Dish are both television distribution companies that manage to serve different markets, so to can different coins coexist. This is especially true when the coins have completely different objectives and are not just chasing the retail point of sale niche.
pdx··on Growing a company that sells miniature construction supplies to $17k a month
That's called a "dollar auction" and it works because the rules are such that the 2nd highest bid still has to pay the money they bid, even though they won't get the prize. Given that incentive structure, it is cheaper for you to pay $21 for a $20 (and lose $1), rather than being the 2nd higher bid at $19, and lose the entire $19.

It is meant as an introduction to other occurrences in peoples lives, where they invest something that they will lose if they abandon the activity. Being on hold is one such example, where you lose the time you've invested in being on hold, if you give up and hang up the call before it's connected. Thus you end up in a situation where you are somewhat trapped.

pdx··on U.S. Charges 13 Russians, 3 Companies for Interfering with Election
It seems that the goal was to promote discontent in general. There were anti-Trump activities as well, such as the post-election NYC protest set up on Facebook.

I remember the one after the election in NYC that was supposedly set up by BLM against Trump, but turned out to be organized by Russians on Facebook

Why shouldn't a corporation, effectively a person, use the vast wealth at it's disposal to influence elections and steer government policy in the direction it wants?

Hmmm, perhaps we should rethink this whole corporations as persons thing.

pdx··on Orcas can imitate human speech, research reveals
I think you're talking about Shell Oil in the 1990's, and their requesting the Nigerian military to help them deal with violent protesters, and allegedly peaceful protesters as well. Yep, that sounds like a problem that needed addressed.

That pales compared to the atrocities that have been done in the name of communism. It's frightening that young people have forgotten those lessons, even the oldest of which is less than 100 years ago.

The ideal of sacrificing the individual to benefit the group is where communism always ends up, and from there, it's never a long slide to the disappearings, the executions and the starvation. The American ideal of protecting the individual, even at the expense of the group is much more inline with the world I want to live in. Happily, you still end up with a strong group, since it's composed of motivated individuals that feel safe.

   > I never said I was a big-government proponent, I just 
   > pointed out that your attack against them was fallacious.
You didn't? Hmmm, well, somebody did. Either you edited or I confused you with them. Fine, you're not big gov, that's good. You and I are on the same team.

Your strawman refutations are not convincing. I would rather you managed to pull up examples that a government might actually in good faith propose, to attempt to fix a perceived economic shortcoming, but that would still be opposed by our hypothetical (not you apparently) big-gov proponent.

pdx··on Vulnerable industrial controls directly connected to Internet
It seems like there's opportunity here. A little box with raspberry pi or similar device and two CAT5 connectors to be placed inline between the PLC and the network, as well as between the network and all other network based displays, interfaces, and sensors. This would allow non-hardened equipment on a non-hardened network to be easily retrofit with encrypted connections.

Edit: These already exist. [1] ;-( Oh well. Just need to have facilities start using them throughout the site.

That's true in theory, but rarely in practice. I'm surprised to meet a real life big-gov proponent that is against government interference in the free market. You are truly a black swan.

   > There's zero support for the notion that it was "Chinese" flooding
You'll have to take that up with Obama then, since it was his administration that specifically targeted China. It's amusing that I'm being attacked by both people who say the flooding was done not only by China and also people who say it was only by China. I think my main sin was implying on this board that Trump did something that wasn't evil.

Actually, the US has an entity called the Department of Energy that does foster solar research. [1] If you're not US based, you may not know about this.

They do compete against each other. They also compete with other forms of energy generation. Did you think there was only a single company in USA that made solar panels?
pdx··on Vulnerable industrial controls directly connected to Internet
It's true that PLC's use ladder logic, which is a representation of relay logic from 60 years ago. There's nothing wrong with ladder logic. It's easy for electricians to understand and change. More importantly, though, it's easy to see the logic flow that makes that conveyor belt that could rip off an arm, or that 1000HP fan, or that critical pump or that critical valve, function. It's important that the safety interlocks, switches, timers, and sensor values that control that piece of equipment be all grouped together visually to help avoid the frequent surprises (bugs), so common with text based programming languages.

If you want to beef up the network security to the PLC, be my guest, but don't disparage ladder logic. It's the right tool for what it's used for.

pdx··on Plunging costs make solar, wind and battery storage cheaper than coal
There are U.S. solar panel manufacturers who were suffering due to the flooding of the market by Chinese imported panels. Is it possible for the man to do anything that won't be seen as evil? If solar is important to you, you should be happy to foster domestic capability, just as we foster domestic food production with farm and dairy subsidies. If you are a big-government type person, as most Trump critics are, this sort of federal level economic shaping should be something you can get behind.

I disagree. The cobra effect occurred because the English provided a market for cobras where there was no market before. There's already a large market for followers and twitter adding itself to that market in such a limited way does not add significant new demand.

pdx··on The Follower Factory
I agree. Just buy them. If they spend $100K a year on buying fake accounts and then banning those accounts, that will be more effective than messing about paying a team of 10 engineers to do pattern analysis. If they spent $2M a year on buying and then banning fake accounts, they would squash it completely.

They're not doing it because they like the big follower counts themselves. They're in on the con.
