Yeah, I agree. At best, I think it's people trying to help, but I doubt they'll get anywhere.

I worked on an ML project for a hospital as late as last year. The FDA was clear - we could develop it in house and use it as a clinician tool, but productizing it outside the hospital it was nearly forbidden. One generic model for all patients and that model had to have FDA approval. Any changes at all required FDA approval. This was what our legal team and a partner vendor interpreted.

"The FDA doesn't want someone in a basement with no medical knowledge marketing a medical device," said one person. These amateur ventilators seem like the kind of stuff the FDA wants to prevent.

It's definitely not an unpopular opinion, especially on HN. Pre-corona I was probably a crazier privacy nut than most so I completely understand where you're coming from.

But right now our privacy is not worth more than our parents' and grandparents' lives. You ought to re-run your moral calculations with the current state of the world in mind. There are literally millions of lives at stake.

Also I am hoping for tech solutions that do preserve privacy to some degree. Singapore seems to have a decent solution where the user has to opt-in: https://www.businessinsider.com/singapore-coronavirus-app-tr...
> a company on the scale of Meetup

Meetup as a website and app is a pretty small engineering footprint. The fact that you think is absurd shows how much we have been accustomed to this "Grow at all cost" mentality.

If I had to take a guess and break down the 200+ employees at Meetup, more than two thirds must be in BizDev, community relations, and artificial management layers.
Out of the 70+ Engineering, a core of 20+ are probably really needed to keep the core app up to date and up and running. The other engineers are working on bets and new products that the company needs in order to justify its valuation and future returns.

Essentially I would say you get 90% of the product with 15% of the engineers. Everything else is small bets to justify the valuation.
Well, I understand why they were added. But they ruin the sombre silence.
That's one way to do it. That's what it is, essentially.

It is not like western channels were truthful all the time. Keeping America, compare fox news information with msnbc. No way both are telling truth about cornavirus.

I don't use Zoom but it looks like someone verified that this is only the host involved with the private chat:

> IMPORTANT: I can only find evidence that Zoom by default creates a log of private messages WITH THE HOST. This happens regardless of whether the session is recorded. It isn't a good design decision from a privacy perspective. But it's not the same as recording all* messages.*

https://twitter.com/rcalo/status/1244404664260411392

It's not super clear what a "host" is in Zoom parlance. Is it the meeting creator, or do they mean the host as in the person you were chatting with?

Zoom is a wall-to-wall security disaster. When my company switched to it about a year ago one of my colleagues showed me how to force any Zoom room, anywhere on the planet, in any organization, to join our meeting. I just don't think it was architected for privacy and security, and you can't add those things later, so you should be prepared for a years-long trickle of this kind of news.

Compared to Twitter/YouTube/Spotify/Facebook, Meetup is a pretty simple app. Most activity is localized to a single group, it's 100% user generated content, and it's pure digital. "230,000 organizers who create an average of 15,000 in-person events per day" isn't in the same ballpark as those other services.

Maybe they have Hard Tech problems like dealing with griefers, but the basic group system looks pretty straightforward to scale with something like Google App Engine.

That said, I'm sure most of Meetup's employees are not engineering.
A machine has inputs and outputs. It’s inputs have to of some level of quality to get outputs of some other correlated level of quality. A consistent supply of quality inputs is correlated with a consistent supply of quality outputs.

The trouble here seems to be maintaining a consistent supply that is sustainable.
Some Good News with John Krasinski #somegoodnews
Startup idea: make it easy for a company to pay for testing for their workforce. If every workplace had a 15 minute test required before an employee could begin work, we could get a lot of people back to work with relatively low risk.

Additionally, the same (or another) startup could make it easy for companies to pay to allow customers to be tested with a 15 minute test. I would not mind waiting outside a restauraunt or supermarket for 15 minutes while my test is run, if it means that I could enter knowing everyone else in the building is uninfected.

I imagine you would supply each business with one or more testing machines, test kits, and some number of technicians to operate the tests and test machines correctly.

The hard part is probably getting test machines/test kits while supplies are limited.

> Is async/await a good idea for an OS kernel, even a toy one? Cooperative multitasking tends to break down at scale,

> Embedding islands of cooperative multitasking in a sea of pre-emptive multitasking seems to make a lot more sense than the other way around.

In my reading of the post, the proposal is to do cooperative multitasking within the kernel, and preemptive multitasking between the kernel and the userspace. I think this is tenable, within the kernel, you pretty much need to play nice with the rest of the kernel anyway. Most kernels don't have effective protection for one part of the kernel causing problems with the rest; although, some do have limited protection against drivers that crash or loop.
Although it's disturbing, economics shows that this is the best way to optimize a complex system.

People with more needs are willing to pay more, generally.

There are caveats, but these are generally built into economics models. Best to let the experts in government decide on how capitalism should play out. A lot of arm-chair socialists around here demonstrating their lack of education.

Craigslist is actually the perfect example. No need to grow 1000% a year and no external VCs to push you to do so. They handle probably a factor of thousands more requests than Meetup and I think they are still less than 50 people?
I am not opposed to some of these measures. A lot of lives are at stake, and also the ability to restart the economy.

But they definitely need as part and parcel of the implementation, a 'self destruct' that goes into effect once the crisis is over.
Plus FB groups have a discoverability problem. Meetup leverages all the power of google for discoverability.
Correct. When a given user downloads chat history, it downloads everything they can see: public chat and their own 1:1 conversations. Zoom has plenty of security and privacy issues, but this is not one of them [1].

I watched the Greek daily COVID-19 update, and the epidemiologist in charge was asked about chloroquine specifically. He said that we are administering it to patients, along with 1-2 other drugs (if they want it), but the results haven't been conclusive yet.

We "only" have 2-5 deaths a day, so it's not a huge sample size, but if the drug were extremely effective, you wouldn't need a very large sample size to see a difference.

the subs don't need to be ready to retaliate immediately to be an effective deterrent. part of the strategic value of nuclear-armed subs is that the opponent can't destroy all of your launching capabilities in a first strike, even if they think they've located all your land-based sites.

You're kind of making my point- demand is meaningless if you don't also account for supply. Also demand for the service correlates to instacarts demand for shoppers, but they're not exactly the same thing.

As long as supply of workers is bigger than demand of workers, overall demand for the service is basically irrelevant with respect to shoppers pay.

I'm not saying they should or shouldn't be paid more.

I'm saying that at a time when you're easily replaceable isn't the time to be a difficult employee/contractor.

As far as charging more, in many/most states it's now a moot point, as emergency declarations means no price increases because of gouging laws. I don't agree with it, but that's where we are. Yet another case of regulations having unintended consequences.
If you have enough money to finance an art heist or buy a priceless Van Gogh from a "dealer", you probably have enough money to not go to jail over an art theft. The collector pays a replica price on paper but in reality pays much more to the dealer. If caught, you just say you thought it was a replica, the dealer says they thought it was a replica, their dealer says the same, and so on until no one ends up with any jail time.

For color, I think it really depends on your willingness to use expired film. I've shot mostly expired film for about 15 years, and once you've tried a range of emulsions of various ages and provenance, it's not hard to figure out how what's going to perform well under what conditions. Even 20 year old color neg performs pretty well with only modest overexposure. B&W you can still get down to about $1/sheet if you're willing to shoot Arista.

I like remote work but the benefit of an office, for me, is that it draws a very clear line in the sand between personal and work time. In a field saturated with infinite work queues and constant pressure to empty those infinite queues, it provides physical bounds that are difficult to cross without being obvious.

When you work remote it's assumed you have flexible hours and when people need more or less of your time, they queue it up whenever it's good for them, your freetime and personal life can take the back burner.

I don't know of any states where Furloughed doesn't qualify for unemployment. And the new federal $600/wk unemployment bonus specifically calls out furloughed employees as being eligible.

You know, I've always wondered why there are so many stories about these middle management types who seem to pay so close attention to things that are _not_ employee productivity. I guess on first glance, it may appear that "looking busy" corrates to "getting stuff done", but why not cut out the middle man and pay attention to what the employee actually does?

In the future, I'm hoping some of the dreams of synthetic biology come true (basically, decentralization of biotech).

I work on that problem in close collaboration with a lot of community lab spaces, and it is surprising how many have the capacity and knowledge to implement rapid testing in their local communities and the inability to do so because of regulation. Biotech, if you run proper controls, isn't actually that hard. A lot of those spaces are now seriously struggling because of the shut down.

The main thing that is stupid about how the FDA is approving tests is that they approve protocols, even though they have lots of controls for input->output. Coming from a computer science side, I'd imagine they'd so something along the lines of unit tests, but they aren't - they're still regulating how the protocol is done itself.
But it's not illegal to watch a video of someone with their consent. Whether an employment contract counts as consent or not is an exercise that I'll leave to the reader, but it's definitely a gray area.
Last year, I explicitly checked with Safari customer service about this, told them this is too good to be true since a regular Safari membership costs 3x of the ACM membership.

Cheers! It looks pretty interesting.

Just to be really clear, I'm not trying to say that poverty makes things harder, or course it does. Really all I want to point out is that even in the worst circumstances we still have the power to choose how we respond or react to them. But again, it's possible that circumstances are so bad that it becomes really difficult to make good decisions. I'm not trying to blame people for their circumstances, or bad fortune, or even their bad decisions (we all make mistakes.) I'm not really trying to blame anyone for anything. I believe that people are generally doing the best they can with what they've got.
Designing Chain Reaction Contraptions from Causal Graphs
This statement really challenged me. I had to consider if I agree.

My first response was that the lefties (catchall phrase for purpose of this reply) I know fret over fairness. To even frame discussions in terms of power is seen as distasteful and largely avoided.

Then I was reminded that many lefties, especially younger cohorts, talk about privilege. In Ezra Klein's interview with Will Wilkinson, they discuss "white privilege" in terms of power. And power is a topic Ezra Klein is far more comfortable discussing (compared to me).

In conclusion, I mosdef agree that we lefties have a more systems-based view, where the relative power of the belligerents are considered. Further, the themes of privilege, equality, bias, opportunity, fairness (as used by misc lefties sub-cohorts) as rhetoric are really talking about relative power.
It didn't completely happen. Only some of the investors sold their shares back for $1. But in general, quite a few investors seem to be willing to get rid of their shares (cheaply), once it turns out that the business won't scale, and the founders want to continue running it as a lifestyle business.

From the article:

> I am following up our conversation a few months ago. KP would like to sell our ownership back to Gumroad for $1. Can we discuss this week?

> Mike had left KPCB to start a new company, and KPCB didn’t want the operational headache of appointing a new board member. Plus, it helped their taxes.

> One investor joined them. We’ve bought back a couple more, since then. I keep the rest of the investors up-to-date with a brief email every few months.

Oddly enough, "the war machine" in particular has driven R&D and science for thousands of years. I encourage you to look into the technologies that DARPA and others have had a hand in creating. Not to mention they fund things like cancer research already.

Smartphones have given millions of people access to information they would never have. Smartphones are the sum of 30 years of computer R&D, making them cheap enough that Kenya has more then 80% of there population online [1]

The issues you listed would take significantly more time then “five years” to cure.
