1. Determining how much real-world protection you have against infection, hospitalization and death is a lot more complex than antibody titers. Everybody is different, every infection is different and even in the healthy population, everyone's immune response to the vaccine will be somewhat different. My understanding is that it's entirely possible a person with antibody levels lower than yours might be at lower risk than you in the real world because of their health compared to yours, the strength of their immune system compared to yours, etc.

2. Antibodies are only one part of the immunity equation. In the long run, T and B cells are probably just as important if not more important than antibodies. This is another area where it's reasonable to expect that YMWV when you get vaccinated.

3. My understanding is that in the context of vaccines these tests are used primarily to assess whether an individual had an immune response to the vaccines, not to make a meaningful determination of how much protection they have (because there's no "formula" for this).

4. It appears from the Delta-related data that any relationship between antibody titers and risk is influenced by variants.

5. We shouldn't rule out environmental factors in the protection equation. For example, if you work in an environment where you're exposed to high viral loads on a regular basis, it seems possible that you could be at higher risk than somebody who isn't even if you have higher antibody titers.

Lots of companies monitor HN for negative posts and respond to them but few do it as well as Stripe.

While some companies just put out the OPs fire, Stripe seems to do better.

I have a rare trust that they’re genuine and will actually follow through with improvements to prevent the same issue from happening to others.

There have been big leadership shakeups at Intel over the past few months (see the CEO change). Long term, if they execute well, they should be back in a good position technically. In the meantime, their only option to offer competitive perf/$ is to lower cost.

AMD managed to recover with a much smaller budget than Intel. I don't think that lower margins for a couple of years will prevent a recovery long term.
Nah the answer is to simply build more.
I wonder if it has anything to do with the machines that are being used to take the images. Maybe some groups have access to one type of imaging machine where other groups have access to some other type of imaging machine.

I don't see why this is necessarily bad. An ML model is picking up on subtle anatomical or physiological differences between races. So what, that doesn't automatically mean the AI is racist or biased...
This shows how a statement can be factually true and completely disingenuous at the same time.

Yes 1/3 are effected badly but we just say that it can have positive effects. Just omitting the fact that it often has a detrimental effect…
Reading between the lines here, and based on the reply from Edwin in this thread, it looks like JustUseApp was collecting money for the virtual cards by pushing through unauthorised payments to the users original card.

So payment using their privacy card would look a little like this.

Merchant --> Privacy Card --> Users Real Card --> Users Bank

Where the step between Privacy Card and Real Card doesn't involve a checkout process and transaction authorisation. In bank speak they're just presenting transactions to the users bank, without first getting a transaction authorisation.

These details are important because presented transactions can't be stopped (that's what authorisation is for), they immediately move money from the users bank to the merchant, regardless of available funds or user consent, they can only be reversed via chargeback. These types of payments are called unauthorised payments, and due to the inability of bank to prevent, you're never really meant to use them, and the receiving bank has very strong rights during the chargeback process.

As a payments processor on the other side of the card network you don't want to be dealing with unauthorised payments. They're trivial to dispute, you're almost certainly breaking the card networks rules, and when they go wrong (which they 100% will), they're extremely expensive and time consuming to deal with.

Additionally in the EU, the introduction of Strong Customer Authentication basically makes these types of transaction completely illegal, and as a customer if such a transaction happened on your account you would have a right to full refund in the event of dispute, and your bank would be forced to provide it even if you had published your full card details online. You're bank would of course then go after the merchant via the card network, and then payment processors like Stripe get caught in the middle, and potentially find themselves liable for money they can no longer reclaim from the merchant, because they've already paid out the money and the dispute only happened 3 or 4 months later.
I suspect there must be some confounder here - like the positioning used for the CXRs correlating with race, based on the methodology used in a particular region / hospital.

Seems the most likely explanation for it still working even when pixellated as 8x8?

Ask HN: Do any companies have managers perform performance reviews?
I hate how my company does performance ratings. I don't like how managers have the ICs basically write their own performance examples. Why waste resource time doing this? Shouldnt the role of a manager be to absorb as much overhead work as possible so their workers can focus on output/outcomes? I feel like this model leads to promotion of people who are just good at telling people what they want to hear or spend a lot more time on documenting and writing up their examples.

This precisely. I don't miss "BlackBerry the ecosystem" but I do really miss "BlackBerry the form factor".

For someone "into" keyboards (as in: taking the time to evaluate different switches to see which one I like best, for example), having to input anything on a smartphone is a really sad joke.

> It's essential to the survival of these groups; local cops more likely to leave them alone if they leave local businesses alone.

Which is a huge misconception outsiders have about this scene. They are Russian-speaking, not Russian, just like English speaking gangs are not necessarily English. These groups may (and often do) consist of nationals of different exUSSR countries, sometimes without even knowing each other personally. They might not even be a single group, just some individuals doing different parts of the scheme. (including "press releases" and "interviews" they sometimes do)

It has been the case long before all this ransomware fad. Russia, Ukraine, Kazakhstan, Belarus, and partially Lithuania had world's top CC theft gangs for a couple decades, and they always been of mixed origin. They mostly steal EU and US cards because it offers better reward/risk ratio, compared to the home countries which are poor. But nothing stopped them from stealing CCs in Russia or Ukraine either, certainly not some mythical cops (who couldn't care less in reality); in fact, skimmers are widespread in those countries as well.

Ransomware groups are the same as CC thieves, it's just a different scheme; they probably avoid home countries for the same reason (same risk, less reward). The state can't possibly have too much influence on them, it just triggers the bullshit detector for anyone who lives in any former Soviet republic and knows about this stuff at least superficially.
Thank you! I didn't know these services even existed, but it makes sense

Was this a case of a leader refusing to be wrong, or engineers thinking "we almost have this, give us another shot."
My speculative guess is they raised the bar on the low-pass filter by tightening up the algorithm after losing way too much to credit card fraud.

It was absolutely scary the amounts of fraud I dealt with running a dropshipping shop a decade ago.

Every bad fraud order that I dropshipped ate the entire profits from a dozen legit orders, and card fraud was attempted on approximately 25% of orders we received.

After a few years I shut the site down as it was just barely making a profit as the fraud costs escalated and I felt I was wasting my time screening every order with my own (imperfect) hand-rolled fuzzy logic fraud detection algorithms and manual investigation of every single order.

I false-rejected a lot of legit customers in the final year, vowing to stamp out the scammers I drove some customers away... it's hard to be perfect when card fraud is easy to achieve.

Actually what the final straw was for me, that made me delete the server, was not the regular identity fraud stolen-card scumbags, but the pathological liars who you could validate as 100% legitimate, but after they received and signed for the goods, would call their bank and lodge a chargeback to get a full refund, because he banks ALWAYS take the customers side and ALWAYS charged me an extra $35 penalty for every dispute I lost (which was every single one, despite sending pages of strong proof showing the customer was a baldfaced lying thief)
Amazing. I'll never understand why "invert mouse" was not the default and universally used. It's so much more intuitive!

The high profile controversies of this nature all seem to be people who have gone off to join ISIS. In these cases, when were they made stateless, and by whom?. Was it when their previous country revoked their citizenship? When they were initially displaced from ISIS controlled territory? When ISIS suffered a territorial defeat?

I know it's a complicated issue, but leaving your home nation to join an upstart state that's ostensibly waging a war against it (as unconventional of a war as it is/was) has to be one of the general cases where it's most acceptable.
Like Go, the error is just returned from the function. The Result<> type is literally defined as “either an error value or a success value”.

It’s up to the caller what to do with an error - panic, return it in turn, wrap it, or whatever else makes sense in context. It’s semantically quite similar to Go - except with better library support (Result instead of returning a tuple) and better syntax (the “?” operator instead of manual checks).
That was my initial reaction as well but they validate on separate datasets from training which makes this unlikely.

The performance despite degradation may be the same phenomenon that results in adversarial examples that are indistinguishable to human eyes, ie we know that neural nets are highly sensitive to visually imperceptible differences.
Python took the shell scripting platform from Perl just like PHP took the web scripting platform. It then extended to web servers (e.g., Django as an alternative to Ruby on Rails) and ML, but that was later.
scikit-learn (next to numpy) is the one library I use in every single project at work. Every time I consider switching away from python I am faced with the fact that I'd lose access to this workhorse of a library.
Of course it's not all sunshine and rainbows - I had my fair share of rummaging through its internals - but its API design is a de-facto standard for a reason.
My only recurring gripe is that the serialization story (basically just pickling everything) is not optimal.
Ask HN: Raising Funds as a Non-Profit
Hey HN,

How does a non-profit go about raising funds? I help run a small (11 employees, most of who are part-time) non-profit located just an hour outside Savannah, GA. We've been given an offer to buy the building we currently are renting. The issue, we aren't making a ton of profit, so we don't have much to put towards a business loan.

The services we offer are already on the higher end of "Low Cost", so we can't really raise our prices much more than we currently have them at.

I've looked at the SBA, and they don't actually offer loans to non-profits. We do get some good funds from facebook (individuals donating) when we ask for donations for tough cases, but when we try to raise funds for capital expenses, crickets.

We are a spay/neuter clinic and animal rescue. I know we are never going to be rolling in the funds, but to have some grants, or even long term loans to help ease the pressure and let us buy our location would be nice.

Any suggestions? I'll stick my email in my profile. If you have any questions that you want to directly contact me with, feel free to reach out. Just put that it's from HN so I know it's not junk. You would be surprised at the amount of junk offers we get.

It's not necessarily bad, if it's actually working.

The fact that it works on an 8x8 massively pixelated version of the x-ray points to the possibility that it's not actually working, which would be bad if you based patient treatment decisions on an training set that was actually teaching the AI something else entirely.
There are non insignificant scientific hurdles that need to be surpassed before this is possible from what I understand. Beth Shapiro breaks it down on the Meat Eater podcast with Steven Rinella.[0]

What the CCP's been doing over the past couple of months is worrying. I wish there were a nicer explanation but it almost looks like they're preparing for war, or at least increasing confrontation.
When Teams first came out, I was among the early decriers (Slack and Zoom were SOOOoooooo much better for chat and video-conferencing/screen-sharing it wasn't funny)

(Kinda like when Slack came out, it was so much worse than HipChat, it wasn't funny)

Then the integrations started popping-up (or being publicized? not sure which is the more correct term) for everything MS-related (Word, Calendar, Excel, PowerBI, Sharepoint...)

The chat functionality of Teams still leaves some to be desired (especially the ultrajanky and inconsistent notification feature) - but the videoconferencing, screensharing, and O365 integrations are fantastic

Good question. You have to understand that "labour shortage" is code for "I cant find workers for the price that I would like".

Clearly there isn't (and can't be) and actual shortage of workers, there can only be increased competition between employers for available workers.

Its worth noting that in recent history, the times when democracies have been closest to actual labour shortages (post WWI and WWII) have in fact been correlated with economic booms.
You mean every society. Every society in history has committed genocide, slavery, displacement.

Before the colonists came, the locals warred among themselves, everywhere.

To suggest that this is a unique trait of the West is incredibly offensive, as it is to blame all violence on European-descended whites, and it supposes that if it weren't for them the native peoples around the world would today live in peace.

Anyone who has read history knows that's just ridiculous.
This is going nowhere. At this point, I can only conclude that you willfully don’t want to admit that the principle actor causing this mess is probably not YouTube.

For what it’s worth, Twitch has not implemented this idea either.
Much of it is sustained by people who are paid by employers who use said open source in their profit centers.
What’s the line from Jurassic Park? “They were so preoccupied with whether or not they could, they didn’t stop to think if they should”
why surprised? seems like it fits right in here.
There are 1.034 million vacancies and 3.277 million people without work that want it.

There isn't a shortage of labour. There is a shortage of decent pay and conditions.

Firms are going to have to get over their cheap labour obsession or close and leave the market to those firms that can.
> Privacy is important, and it's a binary proposition.

It never used to be a binary proposition, it used to be somewhat proportionate because (a) there was a cost to surveillance and (b) there was a cost to acting covertly - crime was inherently local and hard to scale.

So you wouldn't have the police surveilling everyone unless that was critical to the stability of the state (Stasi etc), and it was infeasible to track cash transactions so a certain amount of crime and evasion was tolerated. But it was limited because cash is inherently bulky. Even a few million dollars is hard to carry around.

Now the internet has falsified both of those. Both crime and surveillance can be scaled up and globalized. So it has become binarized, with one of two outcomes: anonymous transactions + frictionless crime, including evasion of tax and currency controls; OR omnipresent surveillance of everyone and every transaction.

Cryptocurrency is accelerating towards one of those two outcomes. I just don't think it'll be the first one.
As a working data scientist I'd say it's completely the opposite: a good tabular data manipulation package is the single most valuable tool in my tool box. And R's packages (either data.table or dplyr) are definitely way better than pandas. There's no comparison.

I would be hard-pressed to find a working data scientist whose definition of data science is "that thing you do with sklearn, Deep Learning and Numpy".

It would never happen. Musk wants to sell cars in China, Tesla has important factories there as well. The Chinese government has a lot more leverage when it comes to these companies, they could simply shut them down without warning and crash the shareholder's stocks.
Which Israel is also not part of.

Israel is only peripherally and reluctantly involved in the confrontations with Russia and China at the heart of 5E interests, and it neither trusts nor is trusted by 5E countries to the level of sharing intelligence sources or tools except in specific, transactional interactions.

American and Israeli politicians like to talk about Israel being America's "closest ally", but those are just pretty words. Israel's real selling point to the US is that it's a low-maintenance ally.
