I think a big question here is, "what is the goal?" A key distinction is whether the NN is intended to handle the signal directly (the NN is the filter) or if it's just a technique for finding filter coefficients (the NN designs the filter for the signal).

For some tasks, like system identification (used in echo cancellation), the NN is the filter - aformentioned adaptive filters are used for this case right now. It can also be used for black box modeling, which has numerous application in real time or otherwise.

For others like Butterworth (and other classic designs) there's not really a good reason to use a NN. Butterworth (and Chebychev I/II, elliptical, optimum-L, and others) are filter design formulae with a closed form (for a given filter order) that yield roots of transfer functions that have desirable properties - I'm not sure how a learning approach can beat a formulae that are derived from the properties of the filter they design.

There are iterative design algorithms that do not have a closed form, like Parks-McClellan. It is however quite good at what it does - it would be interesting to compare these methods against some design tricks to reduce filter order.

There are some applications of filter design that NNs can do that we don't have good solutions for with traditional algorithms, like system identification, another is in optimization (in terms of filter order) and iteratively designing stable IIR filters to fit arbitrary frequency curves (for FIR it's a solved problem, at significant extra cost compared to IIR).

As for topologies of the filter itself that is an interesting angle. Topologies affect quantization effects (if you wanted an FPGA to realize the filter with the fewest number of bits, topologies matter) and for time variant filters (like an adaptive IIR) there are drastic differences between the behavior of various topologies. I'm not sure how it would manifest with a NN designing the filter.

Thank you for such a detailed reply. Couldn't the show stoppers be resolved with some work on the current plane? It's not like they've found out that the airframe is no good and they have to literally start from scratch, right?
This analysis presumes that hospital emergency and critical care capacity is flexible (it's not), that we can expect medical professionals to keep on performing at 100% in the face of overwhelming stress (they will not), and that Canada would somehow succeed at what Italy did not back in the first half of 2020 by doing even less mitigation. An argument in favour of no mitigation would have to demonstrate:

1. covid-related mortality and morbidity would not make up for any drop in other excess deaths

2. short-term stops on all non-critical care would, on balance, result in a significant drop in excess deaths over longer-term stops on a smaller percentage of non-critical care

3. hospital systems and their staff would still be intact after such a large wave. This may sound crazy, but while we're trading anecdotes you may be surprised at how many ICU nurses considered quitting because of how hard the latest surge hit. These are the people who dictate how many "ICU beds" we have, not the physical beds themselves!

4. that we can make any kind of meaningful analytical statement on covid mortality vs excess mortality for a specific age group given the lack of reporting data on both. In particular, data from coroner's offices on covid deaths has a huge lag time at present. Looking at case counts only is a poor proxy given you have to model infection -> death/recovery/discharge lag times, geographical variations and healthcare capacity as well. The HMD link merely provides total counts and proportions with no additional commentary. You can find more specific discussions on the subject [1], but they don't cover demographic breakdowns over time and necessarily maintain a high degree of uncertainty.

I don't think it's controversial to say governmental policy here has been sub-optimal at best. But to say that one extreme approach or the other is what we ought to have done based on woefully incomplete data is a stretch too.

The degraded performance is latching. After a brownout occurs, it will stay on until you get the battery changed or turn it back on. I.e. it’s not based on any fixed percentages. The fact that people can put third-party batteries in and also that different batches of batteries will age differently means that this is probably the best solution.

More info here: https://support.apple.com/en-gb/HT208387

“This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. Performance management has been applied to help prevent this from happening again. Disable…”

As for not (easily) allowing third party replacements, as someone who designs products: why should I (or Apple) have to support third party items? Why should I use engineering resources debugging why a third party touchscreen doesn’t work with my new firmware (this happened to Apple)?

Also, as someone who buys second-hand electronics I don’t want a third-party battery in the phone, or at least I want to be able to tell if there is one in order to reject the phone. I like my house in a non-burned-down state thank you very much. And you just know that the average punter with a third-party battery is still going to blame Apple when their phone bursts in to flames from an eBay battery.

Now, I believe there should be laws to dictate reasonable repair costs and, more importantly, number of years of support to ensure electronics live a long life.

I've got a couple of those records and I can tell you that Adam Beyer and Drumcode still sound like that today, they've really nailed that "far duller than it sounds" sub-genre of techno.

That's what I was playing back then.

I managed to see Landstrumm play two days before the start of lockdown last March as part of the 20 Years of Don't evening at the Bangface Weekender, how's that for good timing? :)

I'm not OP but no, I work from home and only see the people I live with since this started. Knowing if its covid vs the flu wouldn't really matter much to me and either way my behavior would be the same. Frankly it would be worse for public health if I left the house while sick to satisfy my curiosity.

It's all hypothetical, but it's not unimaginable that there are nasty things laying under the layers of ocean snow. Either materials that could poison the ocean, or forms of ancient bacteria that have been dormant (like the anthrax in Siberia that used to be frozen under permafrost).

It would be catastrophic if we released something that could displace phytoplankton in the food chain, but didn't absorb CO2.

It's also possible that those minerals are important to some kind of natural process. I'm not a scientist, so I don't know what that might be, but it's not unfathomable that it's part of some bacterial lifecycle, and that disrupting that bacterial lifecycle could have implications for the rest of ocean life.
I agree completely - techno is hypnotic and almost by design is meant to be heard and not listened to, and I find this really helps me maintain focus/flow while working.

Nano is now the default editor on Fedora since v33.

It makes sense. Modal editors have steep learning curves and were designed for an era of non-GUI interfaces running over teletypes. Everyone today knows how to use arrow keys to move around.

Ask HN: In the current corporate world, what is the back end language du jour?
Of course you can. But it is much harder. I'm just having some fun.

Anecdotally, Rust coerces you into writing sound code and really helps break some destructive habits that C breeds. I rarely need to debug Rust code and when I do the bugs are logic errors not memory errors. It's a noticeable difference. For lightweight contributions to the kernel and "peripheral" contributions (where some big company writes a massive messy driver because the market forces their hand.. not because they enjoy curating and actively helping to maintain linux), the type of discipline Rust enforces is invaluable.

Also, what do you mean that Rust won't solve use after free? The whole point of the borrow checker is tracking and enforcing reference lifetimes in order to prevent using a pointer to memory that's been dropped from scope and no longer has an owner (has been freed). Sure it can't prevent all issues magically just yet (there are limitations) but it's a positive force in the right direction.

Rust forces developers to do upfront what is usually relegated to careful code review. You're forced to think about the memory implications of your code. If the issue is that we can't thoroughly review the abundance of code submitted to the kernel, then e.g. requiring that, unless justified, new patches shall land in safe rust, seems like it would directly address the core issue that there aren't enough eyes on the code. Obviously it's more nuanced than that, there's existing code you can't just say "all new contributions must be rust".. the example is just illustrative.

The existing proposal and work on carefully incorporating rust into the kernel is super awesome. And I'm excited!

> Games for me was able to fill a very odd spot in my mind I think, they were challenging to the extent that you felt like you were growing a skill, and at the same time rewarding [...] stuff that gets your lizard brain going you know.

For me, I see games as a very simple effort/reward process. I can put in some time solving a problem and I get a dopamine hit. It's like junk food for my brain's reward centers :)

The "odd spot in your mind" that you mention, for me, is that cycle: solve a small problem, receive dopamine hit, move on to the next problem. Gaming makes that reward cycle very fast. That makes it efficient, but it also seems to acclimate me to a cycle speed that isn't common in real life.

I find that some hobbies are an acceptable substitute, at least for a while. Most of those involve physical skills that need to be built over time. Some hobbies that I've tried that fill the same mental niche for me include:

* repairing and restoring vintage fountain pens

* metalworking/machining

* building and flying (but mostly building) FPV drones

* shooting sports (always expensive, but much more so right now)

* mechanical watch repair/"modding"

* playing a musical instrument (ukulele is inexpensive and fun)

* photography

* 3D printing - both optimizing the printers themselves and designing solutions in CAD

They don't. The kernel has been under threat for a very long time. Here's an example from 2003: https://lwn.net/Articles/57135/
Ha, that reminds me of the time when we found a loophole in the European train ticket price system: Deutsche Bahn had (and still has I think) a "Europe Special" where you could buy a ticket from any town in Germany to any town in Europe for 39 EUR flat. Our idea was to travel through Croatia for a few weeks, and we wanted to book a train ticket to Zagreb, from where we would start our trip. Sure enough, bahn.de (the journey planer of Deutsche Bahn) offered us a ticket for a train ride of around 16 hours from our home town to Zagreb, through Austria and Slovenia. We would have had to change trains 2 times.

Then things escalated.

We discovered that we could book the same trip, for the same price, but with a different route, making a 500 km detour inside Germany over my parent's town. Then we discovered that bahn.de allowed us to specify a minimum time to change trains. We set it to 24 hours at my parent's town, letting us stay at my parents for a night. Then we found out that we could set an additional via option in such a way that we had to change trains in Ljubljana. We set the minimum time to change trains there to 24 hours. Then we found out that the ticket price was the same if we travelled not only to Zagreb, but to Split (at the coast), which required a change of trains in Zagreb. But we wanted to stay a few days in Zagreb, and the maximum minimum time to change trains on bahn.de was 24 hours. We then discovered that (at least 5 years ago) all foreign tickets were valid for 30 days in Croatia. Effectively, this meant that we could stay in Zagreb for 30 days, and our ticket to Split was still valid.

We got the ticket. After a week of visiting my parents (1 night stay), Ljubljana (1 night stay), and Zagreb (5 nights stay), we arrived in Split without problems. It was a 1,500 km, 7 day train trip for 39 EUR.

The only minor problem we had was the German conductor in the first train after we visited my parents. He just stared at the monstrous ticket in disbelief and had to finally conclude that it was valid.

After 10 days at the Dalmatian coast, we took the bus home.
"Conservative" isn't a view. It's a movement allegiance. So I don't think that qualifies. I feel the same applies more loosely to Brexit.

What's interesting in both case is that both movements absolutely contain rich seams of racism. So if the actual view people are afraid to voice is racism either intent or action, then I would submit that it is in fact good that they are not voicing it.

I also strongly doubt that many are afraid to voice a view that the correct tax rate for high income earners are 3 points higher or lower. But what decades of history teaches is that since overt racism is no longer acceptable, quite a lot of other issues are used as covers for racism. See Lee Atwater's quote here, for example: https://en.wikipedia.org/wiki/Southern_strategy#Evolution_(1...

So I stand by my view that we must look at the specific opinions people are scared to voice and see to what extent they relate to oppressing groups who were previously forced to keep quiet. My bet here is that a lot of what "Conservative voters" happen to be afraid to speak about is the conservation parts of the past that they are rightly ashamed to be honest about wanting to keep.

We're not talking about paranoid conspiracy theories here, we're talking about the inexplicable disappearance of influenza globally, when it should have the same transmission characteristics as corona virus. Corona might spread more rapidly, but it should spread in the same manner.

It's entirely possible that the bulk of people with symptoms actually have a concurrent infection (eg, the flu). We already know the vast, vast majority of deaths have a 'comorbidity.'
Sigh downvotes on HN.

This is correct. Google Flight is amazing at tracking flight prices over time and lets you see dips in the past on a readable chart.

Something that they could make easier would be to forecast exact price changes based on the same flight flight on other dates.
