No one without symptoms needs these tests every month. Meaningful changes manifest with symptoms or happen slowly or both.

As an example of the first case, a person’s white blood cell count isn’t going to go haywire overnight with no other symptoms. An example of the second case is fasting blood glucose: it's important to know before symptoms appear, but is not going to change dramatically (beyond the draw-to-draw/day-to-day variation) in a month, or even in 3-6 months.

Getting these monthly with no medical need is like telling someone you’re aiming for 300% test coverage :-)

Oh. I will look into this issue.
People can get offended at one term or terms and be blind to the fact that they use others that are offensive to different people.

It happens all the time that you use a slur casually and don't realize it applies to someone next to you. If a person is conscious of that happening daily where it's not socially acceptable to say anything, then they may internalize that this is normal and expect others to also have a "thick skin".
The fact that an old web archive gave up the uncensored documents was clearly unintended...

So, this shows that, though "being an accessory" is possible, this is not the case. "Possible => true" is another, erroneous, sophism.
Tell HN: Put all effort into mass testing to stop Covid-19
This is a non-expert perspective. Please feel free to criticize the naivety of it but I believe that it has some substance that is worth considering.

I have been thinking what could be an effective strategy to avoid wider outbreak without throwing a huge wrench into economic gears.

It appears that we can't necessarily expect an effective treatment or a vaccine soon. This would be possibly the most effective solution.

Another solution that has been currently implemented is a widespread quarantine. It does not appear to be fully effective and will cause huge economical cost. The last point makes the deciders to hesitate when considering this option. I am really concerned that the world economy may become halt because of wider implementation of quarantines. Imagine the world when everything is on short supply. The effect to the monetary system would be devastating.

I thought about other possible solutions today in reflection of recent outbreak in Italy and realized that what is missed is more up to date data about the spread of the virus. Currently we are only reacting and we are reacting too late.

We already have a test to verify the presence of the Covid-19. I think what we actually need to effectively fight against it is a mass implementation of self testing kits among the all populace that must be used daily to report back the results.

First effect of this is reduction of fear and the second effect is the possibility to respond more rapidly to smaller outbreaks to avoid wider silent spread.

In principle the kit does not even have to detect Covid-19 directly but only if there is a viral infection or not. Then the specific case could be handled by a medical team to more precisely analyze the situation.

I believe that national states should put their full economic strength into implementing this solution because this will save lives and will keep the society functioning.
With a 2% mortality rate, if there is a breakout then there will be few people who don’t lose somebody they know. I’m worried about my parents. If I stock up on food etc, it will be to enable them stay indoors

I think it is a question of degree. AGI could be 100 years or 1000 years away; maybe it's something beyond our capabilities entirely. But we will probably find ways to augment our own programming tasks to the extent that what humans need to work on is a moving target.
The Orthodox churches really just get to trace their lineage to their respective founding apostle. If we do assume that the apostles that had to travel the least from Jerusalem were the ones whose churches started first, then Syria and Egypt (Coptic) were probably the first. Granted, we're making a big assumption.
I know the concept is a little foreign to the crowd on hacker news, but quite a lot of the world runs on building up relationships rather than on laws or software. Apple enforces this sort of thing because film makers most likely don't want a bad relationship with Apple.
Anyone know if this is anyway related to PANDAS condition (RE: inflammation -> cognitive changes)? We were recently introduced to the condition and my understanding is the theory is inflammation is caused by the bodies immunity response to strep virus (I might be off on that explanation). The idea inflammation could give rise to cognitive impairments/changes would appear to lend some credence (or maybe that is just already established??). We have a daughter who checks some of the boxes on what people describe as the condition and are just getting an understanding.
OTPs are not a replacement for our current encryption systems, but I love them as an example of how encryption isn't going to go away.

A children's book would be a great demonstration of this, and should be protected speech (let's hope). Teach kids how to use OTPs in an illustrated book. Maybe the story ends with 5 year old Jimmy getting hauled away by the feds for doing some illegal math.

Honestly the post for https://grep.app that was posted a few days ago is a perfect example of demonstrating what you can do. He had the CTO of GitHub reach out to him publicly.

I'm pretty sure if you can demonstrate how you can orchestrate a cluster of Elasticsearch nodes, it will go a long way. And if you can contribute to the many discussions they have about Elasticsearch in their issues, it will go a long way to demonstrate your domain knowledge.

As for Lucene, I wouldn't invest any time in contributing to it, as it has been iterated on for over a decade by very smart people. Just build something with Lucene or build something like https://grep.app

I'm wondering how realistic a water or power shutoff is, those seem like much bigger concerns for a hurricane or earthquake. For covid-19 it seems like the municipal authorities will be able to keep at least the handful of people working that are required to keep the grids up (even if just about everyone gets infected, it sounds like ~80% of cases only have minor symptoms).

Restaurants shutting down and grocery stores running low on food seems like a more likely scenario.

Regardless, I've now stocked up on 2 weeks of water and about the same of food. Which is a good idea anyway for earthquake preparedness, but something I'd never gotten around to actually doing. So I'm feeling a good balance of prepared but not too stressed about it.
Let’s explore The project b channel
FYI: You can get get a 50 lbs bag of pinto beans at Sams for $33 and a 50 lbs bag of rice for $17. They will keep as is at least a year and provide, respectively, 76,000 calories and 82,400 calories. Maybe 80 days worth of food for a single individual.

It would be a pretty monotonous diet but better than the alternative.

> The problem with startups building hard tech is it takes a long time to fail

No, not really: you know pretty much from the outset if a venture will fail because nobody knows how to do it. Altman has staked his career on an idea that is guaranteed to fail, for example. There is no step-1 towards a definable goal. Not even sure there is a real goal!

There is no example of a "hard startup" like this in the history of the human race. Only silly con valley hubris could imagine a different outcome than total failure. This sort of thing is what governments are for.
Your comment comes from a perspective of having been abused. While I respect your struggle, stressed analysis is not good when trying to foresee where the next source of abuse will come from.

The commercial surveillance industry is not currently engaging in abuse on the scale the government has previously committed, but the government is not presently doing so either! Yet we are rightly concerned with setups that make such things possible - for example I presume you don't just chuckle at white supremacy protestors for being on the wrong side of history, but view them as a threat that could gain momentum any time.

The commercial surveillance industry is currently poised with a more invasive scope into everyone's personal life than a government could ever have, operates autocratically, and actively resists the desires of its targets to opt out (eg Do Not Track). That last bit puts them deeper into the domain of wielding governmental power than a straightforward monopoly. Trusting the people controlling these companies to be benevolent is a setup for failure.

> You realize that you want to give the government more power

I don't see something like the GDPR as giving the government more power, but rather just shifting it around. Government and corporate power are merging regardless (hence this thread), and it's better to have the result under democratic control than fully autocratic. The real solution is of course for people to shift to using software that they control (and hence can actually represent them), but unfortunately that seems a long ways off, or at least unevenly distributed.
Sort of. I don't think any respective Orthodox church had a distinct recognition prior to the first ecumenical council (year 325), though I may be wrong on that. Plenty of people like to claim "first", but there's no strong consensus on which branch of Orthodoxy was first, though I know there's a lot of cultural pride built up in a few of the churches thinking they were first.
They never said he did. Just that he said it.
I personally can’t really imagine the water or utility systems going offline. Is there a realistic risk or recent precedent of that? Eg, I never heard of that happening in China for example and I think we have better infrastructure here
Not backwards. The point he's making is that hard problems attract talent and capital, which makes them easier to keep going.
If that's the case, then why don't we see capital always rushing to countries that have the lowest tax rates? Last I checked Japan has lots of capital investment, a large economy, a substantial wealthy class, and yet a high tax rate...
We could avoid all that and just have a way of correcting comments (with history, diff, and all that) which would show up upon clicking, say, "show edited version" or whatever. By default it would display the original version, but if someone wishes, one could display the edited version. This way the noise would be hidden. Perhaps to be able to add such corrections to comments, you would have to have at least n_1 karma, be registered for n_2 months, and so forth as a defense mechanism against trolls.

I am sleep deprived. I hope my idea comes across properly. It sounds good to me right now, might not sound good tomorrow. :P It is definitely complicated though and not sure it is worth the effort to implement and maintain.
I am one of the best options traders in the world.

Options dealers don't necessarily sell options. They can also buy them. And "writing" an option means to sell it, so "wrote the contract and sold it" is redundant.

Options dealers are not automatically short all of the contracts that they sell. They may already have a long position in that option contract, in which case their sale is a closing sale. Also, I think you may be a bit confused...a short sale of options is not determined based on one's position in the underlying; you can be short an option and long the stock at the same time (for example, an overwrite is a sale of upside calls by someone who is already long the stock).

Delta is the first-order change of the option contract value, with respect to a unit change in the underlying price. I wouldn't refer to it at "velocity" because while I understand what you are intending to communicate (it is a rate), there is another options Greek called "speed," which is the change in gamma with respect to the underlying price. Wikipedia has a really nice description of the various options Greeks. For the truly curious, Sheldon Natenberg wrote a nice book called "Options Volatility and Pricing" that explains the Greeks better than I or Wikipedia can.

Options dealers who are short gamma will hedge by buying stock as it goes up, and selling stock as it goes down. Their demand for (or supply of) the underlying stock will impact the underlying price in a way that pushes the price in whatever direction it has already started to move.

In defense of my word choice: theory and practice are not mutually exclusive. If you want to be excellent at something, you should aim to learn both. BTW I have never taken an academic course on options or finance.
It's hard not to down vote this.

It's wrong, but the question was about what people are doing and thinking.

I think it's important to see what people think and people shouldn't be down voted for being honest.

But I have to be OT and say "a really dangerous variant of the common cold" - It's killing 14% of people over 80 who get it at last estimates. And permanently hurting a lot of people over 80 as well.

And we don't really do flu season as well as we could, as a society we need to step up a bit in general. We could all prepare for even the flu season more than we do. Common cold, perhaps meh.

Hey dang, my sincere apologies about this!

The app is ready to test and we're reaching out to people who are signing up with TestFlight links i.e., everyone will get to try out the app.

But you're right of course that there's nothing to try on the launch page -- there's only a demo video.

We'll be more careful for future projects, and will only post again about this once we're live on the App Store.

Sorry again!

A very rough rule of thumb is that your body can convert ~1% (probably closer to 0.8%) of your body fat into usable calories per day. If you're going to rely entirely or partially on stored body fat, be sure you have enough to cover your target calorie deficit.
You brought up some really good points. Your second point about interest--that's a great point. I think interest--and, subsequently, focus and attention--are force multipliers, especially in a field like programming, where experience and expertise don't just help you lay more bricks, but actually increase how many bricks you can lay in the same unit of time as before.

The negative effect is interesting. I've heard it said before that non-experts often come up with novel solutions in some fields. That might because of what you pointed out, that the experts are too focused on a certain range of solutions, so they might be missing out on a range that a "layman" can easily identify.
The difference is, a bank only has a certain amount of money, while a grocery store can turn over inventory on a daily or weekly basis. So if I stock up now before everyone else does, I can actually make less of an impact if and when there is an eventual need for everyone to prepare to stay home for a week.
Yes this shows maliciousness, because in normal circumstances when you are sick you spontaneously propose a reschedule.

I'm still learning too, so take the following hand wavey reply with a grain of salt..

What can ML offer?

ML allows you to more easily make predictions from data you already have. An example is taking search terms and grouping them into their subject matter, or taking images and identifying things inside them visually. If you deal in sales, you could predict future sales based on other factors that you believe are correlated (weather? clicks?). If you deal with customers, you could more quickly identify what type of issues people are having (hardware issues? card failures?), or proactively suggest solutions.

Better than programming:

It works better when, to code a new feature, you'd need an abundance IF statements whose logic you'd have to work out by hand. In a very broad way, the machine is figuring out how to approach your task just with lots of examples and scary math. You can get a lot of different "answers" without having to write that much more code, just by trying different data and structures.

Practically it's easier than programming to keep updated as well, because if you can find example inputs that it guessed wrong, you can get automatic improvements to results by retraining with correct predictions.

But of course, the ML system itself is very complex, and it involves a lot of resources to design it, curate input data, and train on costly GPUs. This combination of the system's design, and the learned state of the systems innards, is called "the model".

Input data:

There are many different ML systems designed to use different kinds of input. Some use pure text, image data, audio data, graphs of interconnected thingies. The easiest is when the data is very uniform in structure, grouped into labeled columns (called "features"), with each column having a meaningful value. To train the system, you must also supply a "target" feature for each record, which are examples of what you'd like the system to predict. Anything that fits naturally in an Excel sheet might be a starting point. Generally, you want quite a few examples, but the exact amount of data you'd need varies with how difficult your task is.

Bad input, bad results:

Varies. From the practical side - ML systems usually produce confidence scores which you can use to avoid embarrassment. You can then manually label those confusing examples and feed them back in for training. In terms of the model itself - there are many ways of interpreting and evaluating accuracy, and the system can give you examples that confuse it.

Results, two common examples:

Some systems produce a number as their output - called regression. (Picture a sales prediction.)

Others group things into a set of pre-defined categories - called classification. (Picture a system that can tell if there's a giraffe in an image.)

What those outputs mean, and how they are to be used, is part of the design of the model.
And if I found out that a manager was shipping low performers to other people to deal with rather than doing their job and either helping that person or managing them out...
Facebook absolutely did this. A couple years ago I had a junior dev under me that management would not allow me to fire. And it’s so much worse than just the person searching. His feed recommended my close connections to him just because I watched his page.

He spent 75% of most days working for personal clients outside our company. The remainder of his days were spent pimping his projects on Facebook to build his personal brand. He was not a rock star programmer. His work was beyond subpar and he needed extra time, not less. We weren’t connected but I stalked his profile for time stamps and evidence. He lived at least 1.5 hours outside my locations except for the office.

One day he overheard me and another coworker discussing Facebook oddities and he interrupted, “Facebook keeps recommending (insert my wife’s name) as a connection.” He did not know my wife’s name and they had never been in proximity of one another.
