I'm guessing you mean something like 'how are surveillance systems adapting to the wide use of face masks in public'. *

There are a few techniques including

1) Gait analysis [1]

2) Ear shape analysis [2]

3) Running image recognition on something the person is wearing rather than on their masked face. I can't find it right now but I recall reading a Google research paper a few years back that managed a high (+87% certainty) just based on a person’s shoes. [Edit, after a bit of ‘Ducking’ came across [3] which is a 2016 patent awarded to Disney which is close enough]

Think about how often you see someone wearing the exact same shoe as you are. Same goes for things like backpacks, caps with logo on etc.

At some point 'Bob' or 'Alice' is likely to be carrying a cell-phone (sadly an almost certainty these days) or have to use public transport or leave their house or walk in to a shop and buy a drink on the way. There is a push in a lot of parts of the world to pay by card only and some shops are starting to refuse to accept cash and the same goes for public transport.

With sufficient coverage once you have managed to ‘lock on’ to a unique characteristic (shoe, gait, distinctive item of clothing) even if you don’t manage to get lucky that time you just let the image recognition trawl through all the archived footage and at some point chances are good that you can identify them well enough to know which door to knock on. Given that people are creatures of habit (daily commute, same route, same time of day) even if unable to track back to a physical location you just wait where they tend to be at certain times. The hunter only has to get lucky once, the rabbit has to be lucky each time they pop their heads out.

neither of them are widely used, glib is pretty large(1MB at least, OK for desktop but too large for embedded, for example) and apr's function is limited.

clib can let you integrate small pkgs at will at source level, sometimes it is very handy and useful.
A ranking is different to a prediction. The text notes that. The prediction is dropped.

Arguably, a prediction depends on a ranking but contains less and more data. Less data in that only part of the intrastudent rank is maintained, more in that the ranks are tied to grades.

It would seem that you agree that teachers cannot be expected to produce fair absolute grades, but will produce fairer rankings - which is supported by the articles references.

In terms of the objection being obvious - it is obvious in a political sense that people would quarrel with the prediction being dropped as it both favours them and is more personal. Mathematically its presented as obvious that this is preferable [1].

[1] personaly I object in principal to us estimating grades full stop. I'd have preferred spending the last five months rewriting exams based on covered material and then a mammoth effort at getting kids to sit them safely. However that requires foresight and funding.
The Australian consumer has already lost. This whole country is an exercise in trussing up the public and making sure they pay the very most for the very least.

I've long given up on Australian journalism - at least in the main stream. Obviously the Murdoch papers are garbage, but the Age and SMH are almost (and becoming) as appalling. The ABC and SBS have been cowered to the extent that they jump at their own shadows and now _have_ to include cometary from utter fuckwits like Gerard Henderson or that vast twit Greg Sheridan lest they appear biased. It now seems that the ABC almost has to ask permission to publish a story. The Age was a great newspaper, now it's almost unreadable - apart form the NYTimes and Wapo stories they run.

Google are not the good guys. They are a rapacious monopoly that have their shareholders interest at heart, NOT the Google consumer. And in terms of "trusting them with our data" - like that's the very least we'd expect from a product that purports to do this - and they don't do this for free - WE pay for it.

Like cry me a river Google - like News Corp, they pay fuck all tax in Australia, and, just like Murdoch, are more than happy to take advertising from fake news and conspiracy pushers that does nothing but fatten their profits and damage society.

There is good media out there - Crikey, The Guardian, New Matilda, new Daily etc, but it isn't mainstream, one has to, dare I say, search for it.

It's not a cure or a treatment in the first place. Like one teacher said: meditation is just a shower for the mind, simple hygiene.
People should note that even in non-covid times, UK domestic university admissions is almost entirely based on predicted grades. Predicted grades are much more important than actual grades. The only difference this year is an extra layer of noise in the form of an algorithm. It's a very strange, unfair, socially regressive system (I may be a little bitter).
> personaly I object in principal to us estimating grades full stop

It's clearly a massive kludge - those rankings are only estimates, lots of kids would have performed better or worse than estimated, and effectively they are being granted grades based on a whole load of factors other than their own actual performance. I feel very sorry for them.
I feel like one of the big reasons package managers aren't great with C is because of the way namespaces work.

It's not easy to have a medium-large codebase and just freely add a dependency because maybe this library causes variable or function name clashes. Even worse would be a macro that screws with your code.

There isn't even a simple solution like preprocessing everything in the downloaded library and adding a known prefix to every namespace encroaching identifier I think.
The $30 million was just last time. They got another $10 million this year [1]. Despite the fact that 75% of Australia doesn't subscribe to Foxtel and that SBS would be a better venue for sports content anyway...

It's about funding media organisations.

There's nothing in the terms that means the money goes to hiring journalists at all.
I think there is a typo, as the Death Valley record was set in 1913.

This article goes a long way towards discrediting that record though:

Yes which the linked piece covers but it also says OpenBSD does both KASLR and KARL.
No one ever seems to address the fact that Blockchain still doesn't magically provide trust at all. It still needs people to participate for that and provide their resources (miners).

And for people to participate they need some incentive or reward. So how do you ever motivate enough people to participate in your distributed ledger?

You can give them blockchain tokens of course, but now you've created a new currency again with all its associated problems. Hardly a solution for your original problem of low trust.
> It would be much easier if the author of webpages were to declare themselves, sort of a Pagerank but applied on a person/topic level. It could/can be done with structured data. This of course has privacy implications but it keeps the publishers as transparent to the search engine as possible. Verification of sorts would be needed so other people don't use your authorship details on their own site. It's the kind of social fabric/data Google could've perhaps used Google+ for.

This was actually done back when Google+ first was launched — people could attach their authorship and it would be displayed on the search page, and you would also see a list of “experts” for particular categories on the right hand side when you searched for things like “python” or “poker”.

I believe it disappeared with the rest of Google+, because no one actually cared.
This is about to get interesting. Similar story to NYC in that they go after people that move to NJ or CN, work from home and choose to pay taxes to the state they live and work in. NY claims they are choosing convenience and because their office is in NYC they need to pay taxes there. So states like NJ miss out on a lot of revenue.

There are local politicians in NJ now talking about this. With so many commuters possibly not going back to an office there’s potentially a few billion in tax revenues at stake.

Most states have reciprocal deals with neighboring states so that you pay taxes where you live even if you work in the adjacent state. NY does not and for obvious reasons. California either and I’ve heard California will claim your owe taxes even if you move far away but the company only has an office in CA.

As reports of these states chasing down money that is arguably not theirs gets around it will be interesting to see if congress acts. Especially if CA’s wealth tax happens which they claim will tax any wealth over a threshold even after you’ve been out of state for years.

I built this over 2 days, Friday night and Saturday. Thanks to the new search endpoint in the v2 Twitter API, I was able to go from concept to launch really quickly. I definitely wouldn't have been able to build so quickly on pre-v2 APIs (and the user experience would've been wayy more janky).

I’m thinking about monetizing with a “top up credits” / pay-as-you-go pricing model. Would love advice from the HN crowd :)
Yes I do remember reading a while back that this used to be very common. It started dwindling in the late 17th century and was pretty much obsolete by the early 20th century.

This period was often used for prayer, or writing, or sex, or even for visiting the neighbours.
That's not waterfall.
With the Librem Phone, the extra money is also paying for the development of the software ecosystem. I would argue that's worth the investment.

For reference, a lot of the Pinephone distros are using the software developed by Purism. I am not saying that's bad, thats the whole spirit of open source!
That's debatable but ultimately meaningless when it comes to tax obligations.

OpenBSD is brilliant and I'm sure it runs on a multitude of network hardware, that you don't even know you encounter on a daily basis !

Given that this is HN, many of the readers might already know the "story" and I'm sure it has be told many many times... but I will tell it anyway since it's so funny (to me at least). Also we probably should not admire or approve of this sorta behaviour.

Right so disclaimer out of the way, the story goes that:

Someone once incurred Theo de Raadt(Main guy at OpenBSD) ire by asking the wrong question at the wrong time, and Theo de Raadt hacked his router and remotely remapped his keyboard.

Now that is funny - Wrong but funny:)
Unless things have changed in the last 24 years * , offers are based on predicted grades, and requirements are set on the actual grades achieved in order for that offer to transform into a place. Those students who did not achieve the requirements and those universities who still have places to fill then enter the "clearing" process to match up.

Were you predicted worse grades than you achieved, and as a result not offered places where you would have liked?

( * they may have, significantly, it's been a long time)
Different teams, different budgets. The app may also be made by another company.
You see the problem right?

You can damage most software vendors with just #1.

Then #2 is even worse.

#3 you already own them because #1,#2 let you download a poisoned msi to the machine. You can get cleaver and dynamically change the hash per download as described year ago when signature based AV was all we had, you dont need this trick.

Or... you could just drop powershell, python and execute it and own the machine without trying so hard with just #1 and #2.
I was almost certain changing your IMEI was a serious federal crime in the US.

It would keep exclusive institutions exclusive.

Much of the UK educational system is like that.
For example, I don't know how it works elsewhere, but in England, certain students will only be offered certain exam questions, in the same subject, if the teachers determine you can take them.

So immediately, you can see some aspect of these grades are based on a subjective standard. In this case, at the discretion of teachers. One could easily argue that this Covid exam fiasco is a supercharged manifestation of those very same principles.

In the above case, obviously, all students sitting the same exam, for the same subject, should see the same exam papers.

I mean, why would they not?

I suspect the obvious answer would be the cost of teaching resource. If that's the case, this then becomes a political argument, not a technical one. But the 'exam algo' debate is definitely a technical one, and it can and should be used as a lens to examine (pun) a number of questionable practices in the UK education system.

IMO he has mostly satisfying answers. He agrees with some minor points and he doesn't address important stuff like cutting out parts of graphs, but I don't think the criticism is strong enough to conclude that the book is "riddled with scientific and factual errors".

I have read very few strange things on Pubmed, but still some seems out of place in a medical/biology publications repository [0-2], so I have a question about indexation on Pubmed, is it possible to tweak this indexation to make it more stringent?

> Open Architecture with no black boxes.

> ‘Open’ means that you’re allowed to understand exactly how it works and that there’s no mysteries. It means having the blueprints of the machine, not a free machine.

No, this is 100% incorrect.

The Power ISA, i.e., the software/hardware interface of the CPU, is open source. This means that if you want to build a Power CPU that implements its software interface, you can do so "for free".

That's it. You don't get "the blueprints of the machine", you cannot look into how the CPU work internally and understand it, etc.

That's like having a standard API that anybody can implement, e.g., the C standard library, but which Apple, Microsoft, etc. ship as a black box binary blob, so you can't understand their implementation, search/fix bugs, etc.

So no, your claim is completely incorrect. The benefits of an open ISA only apply to those wanting to build their own CPUs, which for Power is just not even a handful of companies, none of them making their blueprints of their CPUs openly available...

For end users, your machine is as open/closed on a system with an open ISA like in one with a closed one. People paying 10k$ for a Raptor II in the name of openness are throwing their money away.

This is a completely different situation than, e.g., RISC-V, where not only the ISA is open-source, but the VHDL implementation of many RISC-V cores is also open source, and you can buy those cores today.
I do find the system of using predicted exam grades odd.

But using grades pupils have achieved during the previous years(s) seems fine to me and can potentially erase the issue of having a good/bad exam day.

In some countries, either they use exam results and/or they look at report cards for the previous years.
In Scotland you do Highers in 5th year and apply to universities during 6th year after you get your grades.

Motivation for working hard during 6th year can be difficult if you get an unconditional offer based on results you already have....
We badly need some sort of industrial fish farming at a large scale. Oceanic fishing at this point is basically like hunting gathering at an industrial scale: we just catch whatever we can and who cares if it grows back, not our problem, "nature" will take care of it. The same way we seed, till, etc., we should be doing the same thing with oceans and "hunting" aka fishing should only be allowed as a hobby.

In a somewhat "positive" side effect of what they're doing, traditional Chinese medicine will probably go extinct together will all the fish and animal species they will wipe off the face of the Earth...
At what point do we shift our investment in time and energy from building models like those mentioned in the article to the bigger picture? Maybe it’s just my perception but it doesn’t seem like we have very many people thinking deeply about what models we should build and to what ends. Instead we are just building the models and hoping we can put them to good use afterwards.

For example, what’s the end game for the cellular signaling modeling outlined in the article? It seems like the result isn’t valuable in and of itself, and it can’t be much more than that because the scientist “doesn’t understand it, and doesn’t think any person could.” So we now have an equation that expresses constants within a cell and that’s it. We don’t understand it and we can’t put it to good use. So was that time and effort well spent? Do we just put this work in a drawer so we can pull it out if it could be useful at some point in the future? Is that what we’re doing with all the similar advances in modeling?

There’s nothing wrong with knowledge for knowledge’s sake, but I think we’ve way over indexed on the tools and predictions side of the system. If we continue to constantly create new tools/models/predictions we might find a use for them by chance. It just seems more efficient to focus on what outcomes we really want and then put the models to work in pursuit of those outcomes. Perhaps we focused more on the outcomes in the past because we didn’t have the technological horsepower to constantly churn out new models.

Maybe I’m wrong and there are people working on the big picture. Are there modern day philosophers doing this work? Do they make up a significant portion of the work being done? If not, why?

Ecommerce Is Eating the World – Join EasyPost
I agree with most of the points you're making, but I do not think that the exams would need to be tailored to just the part of the curriculum that the students have actually covered.

If one student does not know key parts of the curriculum and the other does, then this should be reflected in the grade no matter what caused that difference, whether one of them got more schooling or studied on their own or took some out-of-school tutoring.

And if a diligent student who got all A's before missed out on key parts of the curriculum that's required for further study, then the final grade should reflect that they do not (yet) know the subject as expected and are going to need remedial support, i.e. their final grade should not be an A, the exam should ask for the expected content (no matter if it was not covered in school due to Covid) and the exam results and grade should illustrate whether the students have learned it otherwise or if there's a gap.
