"hacker news is a hivemind." Hm. I've heard this said before but I don't know what it means?

"I don't agree with everything you say (one can argue there is economic value in staying home during an outbreak of a highly transmissible virus) but I do think you are right in a lot of ways (it's a perverse incentive, and unproductivity should not be subsidized in general)."

Cool. I would advise against agreeing with everything I say ha. Look if people want to pay their own way in terms of UI over their working years and save up some sort of 'emergency/flex account' managed by the gov for when the inevitable storms roll through I think that's a fine idea.

The fact that it is forced upon all earners individual and businesses, and ultimately only used by some and then abused by a chunk of those who use is a different story. It's the equivalent of stealing money from your neighbor and their family! Just because the gov sits in between the two parties and forces the transaction somehow socially acceptable, even laudable? WTF.

As I've mentioned above, beyond normalizing this behavior is the sneaky side effects it has on the unemployed recipient...backward incentives, dependencies via erosion of self reliance.
> as a healthy person does wearing a mask has any effect?

This all depends on the type of mask and how tightly it fits against one's face.

A mask made from cotton has been shown to be ~70% effective at filtering a virus from droplets in the air: https://www.researchgate.net/publication/258525804_Testing_t...
I’m guessing easier to break, causes more troubleshooting issues, looks cleaner without it. The less moving components there are, the less warranty and tech support they probably have to field too.

Swapping out devices is probably less costly than fixing parts of it.
Logical changeset extraction itself does not in itself provide a replication feature from what I can see of the wiki [1]. 2ndQuadrant sells BDR which is built on top of it.

I stand by my words. At least I put my name on it. The parent comment was mindless and petty as was already pointed out by other commenters.

Telling people who are probably working their asses off to get things done that they are subpar because (because of what exactly?) I think is enough reason to be at least a little bit derisive about.

I added some additional information to point out there might be a good reason to do test at night since for example, SST missions tended to launch on mornings.
So I'm pretty skeptical of the distance aspect and the plant aspect. I'm actually not skeptical of the "animals" claim.

Cats cuddle with you. They enjoy being petted. So do dogs. And so do humans! I have a dog whose primary pleasure in life is snuggling up to you on the couch and getting petted. This is not surprising; dogs, like humans, are social animals. And this is a symbiotic relationship. It's pretty well known that therapy dogs significantly reduce stress, including physical markers of stress such as blood pressure and cortisol levels.
There were editors, proof readers, and typesetters involved. These were people not products. Not machines. The technique was human labor.

The tradeoff is this little box I am typing into and the ability to read what you wrote three hours later from anywhere in the world. We don't have to coordinate all those people. Or pay them. But the output is unlikely to be as good as what a team can do.
Wiring views to reflect model state correctly is a problem that exists regardless of framework, how effeciently your framework deals with state changes from single or multiple sources is the problem I have with these pure functional frameworks. We've recently backed away from React Native because of the performance problems inherent in its design.
Generally NPR is slower and cleaner in their reporting (except when it comes to fair coverage of political candidates). This is disappointing.

This is correct - you can confirm from the CDC charts here: https://www.cdc.gov/lyme/datasurveillance/maps-recent.html

Note that cases are reported by state of residence, so even the handful of cases in Arkansas and Missouri are probably attributable to travel to the upper Midwest or Northeast.

However, the Ozarks do have a high incidence of Rocky Mountain Spotted Fever, so you should still be careful about preventing tick bites and removing them ASAP: https://www.cdc.gov/rmsf/stats/index.html
Yep, that's right - I just talked with the founder today!
Why does it matter? If they're fired, they stop being the company's problem. As long as they don't have to pay their salary, any method works.

In fact, it would have been more efficient to simply turn off their computers without any warning and then send them a text informing them about their situation. That way, the 'time-in-flight' is just a few minutes.

I highly recommend the biography "Boyd" about this man. I think I got the initial reco from this site.
For some cool stuff about mirror development, I recommend reading up on the Hale telescope. https://en.wikipedia.org/wiki/Hale_Telescope

Some massive improvements to mirror making techniques were derived from the construction.
Yeah if it was just about having enough beds somewhere then we wouldn't have issues. But there is a lot of mental health, addiction, and trauma -- often feeding off each other, e.g. people with metal health issues turn to drugs to self medicate -- and that requires more than just a place to keep them.

In a lot of cases it's more about harm reduction (to themselves, and to the local community) then getting them fixed in a home. Cuz you're not going to rehab some of these people.

The tiny handful of people who are homeless because "they don't like the rules, man" are statistically irrelevant.
Yes it is bad, you royal jackass.

Reminder: You can fire and lay people off while still conveying a sense of respect and dignity.

This was absolutely not that. This is why people hate tech startups. They are pieces of shit in most cases.
Note the UK process for comparison: https://www.gov.uk/staff-redundant/redundancy-consultations

This would have required a minimum 45 days statutory consultation period.
It's insane that companies become "big" when their whole product and business model is unsustainable to begin with. And at least if you're operating at a loss you'd think that you would do everything in your power to stay small and not spend even more money on lots of employees unless absolutely necessary.
I'd rather flaws in test procedures and practices be identified in this manner rather than later in the rocket's life.

What do you mean by debug ? for ad-hoc testing during development everyone around me sticks to Postman.

For things that involves flows or logic I tend to write code, Python in my case but everything works, with some basic test framework around it. You can even use Robot framework or Karate if you don't want to write real code
That is truly amazing. I know precious little about encryption, but I assumed everyone knows that ECB is bad and that CBC is the only sensible way to do AES.

I’ve just discovered that I’ve been living for with blood parasites from my travels many years ago. It’s been really terrible, chronic inflammation, years of doctors telling me that nothing is wrong. I only discovered it because one of the symptoms got so bad without explanation that I bought and refubished an old microscope and started looking at things for the last few months.

First I saw their eggs, and I thought they were white blood cells. There were millions of them, but my WBC counts came back low. After a few months I finally saw one of the little monsters. I sent photos to my doctors and they ignored them. Finally, I got a video call with a doctor, went through the whole procedure with them and found one on the call. This got their attention, but they couldn’t re-order labs because they had already come back negative. The proper tests/treatment are very specific and expensive in the US, nearly impossible to get approved by insurance, although they are given for free in the third world.

This stuff happens. Native people generally develop some form of neonatal immunity or tolerance. Travelers mostly stay safe in leisure travel, but some studies show it to be less rare than expected. For me it took a combination of an untreated flesh wound, and a flood of contaminated water.

I’m reminded of the blood parasites support group in Fight Club. I can’t even begin to tell you how much of my life I’ve lost to this.
Putting Jared Kushner in Charge Is Utter Madness
Same for me. I've had one of the worst colds of my life in mid January. Symptoms were sore throat (very briefly), light nose congestion, a very strong and long-lasting dry cough, chills for about 2 nights, light fever and light chest pains. Then, I was worried about developing a bacterial pneumonia.

When I heard about the coronavirus in the beginning of February, I dismissed the possibility because of the timeline. How could it have arrived so early in Portugal?

I still don't think it was Covid-19, but recently got doubts when I heard it might have been circulating in Italy before January. We also had one of the first Covid-19 cases in the region of Lisbon in an institute co-located with ours. Many of my colleagues are Italian and most of them visited Italy during Christmas until New Year. So I'm no longer sure.
This doesn't add up. 100M rows isn't a lot. All of those databases can do it, and commercial systems like MSSQL and Oracle have millions of R&D invested into performance and geospatial features.

It's not realistic that Postgres would outclass everything else like this.

Depending on your point of view, only the second "reason" is true.

Software switches like the one described in the article (despite its name) are definitely easier to break since they can be hacked by software. No need to have physical access to the computer. A discrete switch definitely looks cleaner than a piece of duct tape, and is much easier to turn on/off. If you want to "switch off" your mic, bad luck.
The polymerase in most RNA viruses is an RNA-dependent RNA polymerase, an enzyme that makes copies of RNA. So what happens is: a single piece of viral RNA comes in the cell. Then it gets translated by the cell machinery, producing the polymerase enzyme. That polymerase then makes more copies of the viral genome. Which in turn gets translated into even more polymerase. Which then make even more copies of the virus... That is where the fork bomb analogy comes in.

https://en.m.wikipedia.org/wiki/RNA-dependent_RNA_polymerase

That kind of thing doesn't normally happen to us because we don't have those enzymes that can make copies of their own messenger RNA. Putting those fork bombs in production would be asking for trouble :)
They dropped support for Vizio tvs that were only four years old.
It kind of does: you don't want it to arrive in your inbox. It is implementation detail how you arrive at that effect. Personally I find adding a silent filter to be superior option in most aspects: it is quicker and foolproof. Surely it won't "educate" the sender, but TBH I don't think your current method is doing so anyway.
If you live somewhere that Lyme disease is prevalent (much of the eastern US) and spend any time doing outdoorsy stuff (or associate with people that do), it's hard not to be aware of Lyme disease. You'll also likely know people who have had it, and other people who have persistent symptoms after an infection.
Even if you elect to "rip off the band aid" there are about thousand ways you could go about this in a more mature and professional way. A couple of things come to mind:

- Deliver your message with empathy and context as to why the decision has to be made for the survival of the company.

- Deliver the message in a way that scales. There's almost no point in having a webinar if there's not going to be a discussion anyway.

- Offer assistance to those being laid off to lessen the blow: paid leave, coaching, extended health benefits etc.

- Preface your message with the good stuff (point above) and explain why the company has taken any type of measure to lessen the impact of this sad but unavoidable news.

- Set up a way for ex-employees to keep in touch instead of locking them out completely. Protecting corporate assets is understandable, treating people like disposable trash is not.
While we're all here talking about databases I've got a question for the DBA/well versed software engineers.

What database or database design strategies to be used for an analytics dashboard that can be queries real-time similar to Google Analytics?

The first real scaling issue I've come across (as a junior dev working on a side project) is a table with 38 million rows and rapidly growing.

Short of just adding indexes and more RAM to the problem, is there another way to design such a table to be effectively queried for Counts and Group Bys over a date range?

Iimagine things can't really be pre-comuted too easily due to the different filters?
Diplomacy: The Map That Ruined a Thousand Friendships
“ It has to be some electro-magnetic based communication instead of currents so the circuit has to be more complicated. I doubt it's done without using any kind of software but would be glad to hear otherwise.”

You can do the whole thing in analog fairly easily. The hardest part would be to get the magnetic sensor integrated into the same chip, but I guess that’s been a solved problem for a while.
This is why science asks more specific questions than "Does Reiki work?" We shouldn't let a self-proclaimed Reiki Master determine what we look at.

I'd also add that we don't have to let them determine our terminology, either. If the touch parts of Reiki work, then there's no reason we should add an air of validity to all of Reiki by saying "Reiki works" instead of "touch therapy works" or something similar.
New York City, that is. Not New York State.
MSN verges on the absurd. An outbreak among farm workers is extremely unlikely given their social distancing is measured in miles.
Yesterday, the White House stated that they are about to issue revised guidelines around masks likely today or tomorrow. They are likely to advise people to wear cloth masks.

At this point, I don't think anyone is really arguing that "masks don't work." Dr. Birx is worried that people will see masks as a substitute for other measures like social distancing, hand washing, and avoiding touching your face.

There is a growing "grassroots" movement advocating that everyone wear homemade masks -- #masks4all

Makes sense not to wait for the CDC on this on. Every day makes a huge difference.

Yes it is bad, and yes it looks bad.

Your post is getting downvoted because it displays a tremendous lack of empathy, and because the company in question displayed a tremendous lack of professionalism.

> It's sort of ripping off a band-aid: it's better to have it done all at once, than dragging it out over the course of a few weeks.

It could have been done in a week, and in a way that 1) maintained security/access in a reasonable way, and 2) that allowed people to get their shit in order.
I think it's pretty justified because of the sheer number of grade schools and healthcare companies are on-boarding with them because of name recognition. Perceived security isn't good enough when dealing with sensitive industries like that.
Sure, but it sounds like docs are now updated by the relevant developers. The "docs team" sounds more like a project team to overhaul the state of docs at the time, which is now complete.
I love animals and I agree that Dog Therapy is effective for the reasons you state. I fail to see what any of that has to to with Reiki and it's claims of tapping into the "Universal Source" and manipulation of "Healing Energy".

Hugs are also beneficial and cause documented positive chemical changes in our bodies. No imaginary mystical forces or increased "vibrations" needed.
Isn't the point of getting inside the opponents OODA loop to force them to make decisions faster than they are able to sensibly and ergo force wrong decisions. If you get inside your own loop by hurrying your decision making forcing wrong decisions how is that sensible?

It also seems obviously untrue that acting on a wrong decision is better than doing nothing. The results of a wrong decision could of course be worse than the results of not making a decision in haste.

If you're already at the point of being forced to make decisions then you've already screwed up? You're being reactive.
But in order to get them you have to congregate. :\
There's a reasonable number of people out there who would be very interested in a disambiguation of scale, architecture, implementational wins/shortcomings, etc, about these two cases.

Codebase size? Entropic/organizational complexity? Word style? Environment (custom/standard)? Standard(s) used? Ease of debugging? Testing methodology used?

I most definitely am not literally asking for answers to this set of questions (considering the cases of a bank and an industry that presumably doesn't want to be known for its software) - I guess I'm just being exact in the gist of my curiosity :)

The only interesting illustrative example I can provide is that Mattel once used Forth for its toys (quoting previous times I mentioned this: https://news.ycombinator.com/item?id=21823216, https://news.ycombinator.com/item?id=17755287)

I don't know of any recent case studies.
There are no shifts for engineers when it comes to testing events. From my experience they are usually all there.

Yes, during the production process you've got shifts of workers/technicians/engineers. Testing: it's all engineers plus enough of technicians they like the most (by negotiating to shuffle around the shifts where possible). It's probably the same at SpaceX.
The Starship is made of steel. It costs only 3% of the price of the previous design. So they can burn through a lot of prototypes to improve design and manufacturing, before costs becomes an issue.

Why San Francisco does sourdough best
> I’m curious how biologists thought callouses formed before this research? Magic?

The answer wasn't really known, and the knowledge of this mechanism didn't really exist. This release also doesn't specifically address calluses, though past research (e.g. https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1365-2133....) doesn't quite result in a definitive hypothesis either. Could be mechanical, or could be the body's response to damage to specific cells or structures in the skin.

(I may have misstated the above. A dermatologist or other researcher focusing on skin will likely have a more accurate answer than what I could dig up.)

P.s. cynicism is generally appreciated in science, but derision... not so much.
GCP does have HA for postgresql: https://cloud.google.com/sql/docs/postgres/high-availability
There's probably a whole body of unexplored potential in therapeutic systems that rely on varying types of placebo or psychosomatic effects. Modern medicine has a very strong naturalistic underpinning to it, which biases it towards pharmacological types of interventions and tends to write off anything else as fake quackery or superstition.

Granted, most of it IS fake quackery and superstition, and whatever the thing is the pharmacological intervention is probably going to be more effective in a more predictable and repeatable way than most traditional practices. But there's clearly some measure of relief people get from a lot of the traditional systems that we could learn from, even if it means we do a little dance and chant while we administer the ibuprofen.
What I love about SpaceX is that they truly take on the start-up approach of fast iteration, in complete opposite to most of their competitors.

This is a silly loss, as it sounds like it was a test procedure error and not a valuable experimental failure. But even then, how much is lost? The rocket was built on-site in a tent, welding some cheap steel together. They've got more test articles being built. The engine is probably salvageable. This is a month or two set-back at worst.

And just like when our software fails in a silly way, I'll bet you there will be new automatic tests, procedures, etc, so that this kind of error can't happen again. They'll learn, iterate, and continue to move fast (and break things).

With nearly all of their competitors, any kind of failure like this would be millions of dollars lost, months or years of setback. This fundamental difference is why SpaceX is slowly coming to dominate the industry.
Where does it say this is from MIT and Harvard?
Re-Ops – One REPL to rule them all
Heh, I agree with you minus one consulting case: over a span of 10 years, my client had built an unholy disaster of Oracle PL/SQL on top of their not-great schema. While I wouldn’t call it unstable (queries did always return), query performance would vary dramatically even with the same inputs on an isolated install. I spent more time than I should have trying to track it down, but ultimately gave up.

What was my task? Add XML export into a poorly done XML schema, and do it all in PL/SQL; the data that went into the XML was a mixture of normal queries and computed PL/SQL results.

That schema + stored procedure monstrosity sticks out in my mind as the most unholy disasters I’ve ever worked on.
This is great but this encourages people to go out. The exact opposite of what we want right now. Deliver to people or just give them money so they can order online. We need to stop being greedy in this time.
