Workers are based on the Service Worker API, not based on Node.js APIs. So, Express is not likely to work out-of-the-box; it would need to be rewritten to be based on Service Workers.

The good news is that the Service Worker API is more modern than Node, e.g. using Promises instead of callbacks, which IMO makes it a better experience to work with.
Planes are updated, just an FYI. And most GA aircraft are older. That's how most people fly, by buying an aircraft that is the price of a car (<$50k).

I fly a Cherokee 140. One of the most common aircraft, as with the Skyhawk. My fuel consumption is 8.4gal/hr at 75% mixture and 5.6gal/hr at 50%. Assuming I'm doing an average ground track of 100mph (for easy math), that's 12-18mpg (not counting that I'm 100% rich at TO and LND).

I wouldn't exactly call it fuel efficient, but it isn't burning like an oil refinery on fire either. I also don't pay $5 for gas ($4.09 today, but it isn't uncommon to see it at $3.50). But you do have to consider speed and time to destination if we're going to compare to cars.

One thing to also consider is that avgas is still leaded. And for anyone interested, here is the POH for the Skyhawk[1] and Cherokee[2]. Note that fuel consumption will be in hours or gal/hr when discussing aircraft. Mpg doesn't make as much sense.

Ask HN: We're being censored. Why?
This article (https://news.ycombinator.com/item?id=16576569) was flagged and removed from the news pages.

Not even a flimsy excuse was given.

It is such an important topic - a person who ran a black site and destroyed the evidence before Congress could see it is now able to look at all our dick pics. This one shouldn't be shoved down the memory hole.

My comment on it is permanently compressed (even when the thread is opened in an entirely different browser) and has been stuck on 11 points. It's fucking weird, and I've never seen that on HN before.

As another commenter pointed out, informative and well sourced comments on the thread are flagged and grayed to oblivion. While most commenting has stopped since the page disappeared, there are a number of suspicious commenters still deflecting and inciting people in dumb directions.

Is this who you are HN?
> Cloudflare currently entails correlated risk, for lack of a better term. A government intrusion into CF represents access to thousands and thousands of sites' decrypted streams. This is a huge target for the US, Russian, and other spy agencies, to the extent that I cannot believe you're not already compromised.

Why is this different from a bunch of people running a LAMP monoculture on their own individual servers?

If anything, Cloudflare can use economies of scale to staff a dedicated incident response team, assuming that at all times they are already compromised and trying to stop each attacker. They can invest in systemic least-privilege isolation. They can test the latest upstream versions of software in CI and deploy patches quickly and have 24/7 on-call staff to manage those deployments. I can't do any of that on the Raspberry Pi in my bedroom. If an intelligence agency or even a not-that-intelligent agency decides they want in, they just need to wait for the next zero-day in L, A, M, or P, and bet correctly that I'm not going to patch and restart my server until at least when I get home from work. Scaling this to everyone like me is just a matter of putting their exploit in a for loop.

And I do server maintenance as my day job. I've maintained a many-thousands-of-users shared web host that has been broken into. I certainly don't expect myself as a hobbyist to do a good job of maintaining my systems; what about the person who just wants to run a website and has zero professional experience being a sysadmin?
> Inbox (try downloading attachments)

The only times I got issues with this on Firefox was due to some add-on (Disconnect for instance). On Firefox out of the box I haven't had issues with downloading attachments lately, even with the add-on on.
In no way could my Android phone with Termux serve as substitute for my Linux desktop/laptop, but it is handy.

Presumably the only real solution is using desktop Linux on a device, rather than Android.

Is the GDP Pocket [ https://medium.com/@tomac/qpd-pocket-7-the-return-of-the-hac... ] included under your category of sweat-inducing devices? It looks handy, and even seems to have some sort of pointing/TrackPoint-like nub. I haven't used or even seen one in real life, but I've heard good things.

I'm not convinced there's anything that will replace an X-series ThinkPad. Non-phone devices that fit in our pocket and run Linux are rather appealling, and I'd love to have one, but I still don't imagine it could really oust my ThinkPad for most purposes. I need at least the X-series sized screen for most of what of I do.

What kind of practice do you do? I did an afternoon seminar with him and there the breathing exercises had great effect and the ice batch was no problem. Now that I am practicing home I am having trouble getting the same effect from the breathing. I also did cold showers over the summer but now that it's colder it's getting really hard. I just don't seem to get used to it.
> a regex that performs very poorly

Would that still be true if you limited the regex support to DFAs instead of NFAs? I can’t think of a single use-case for backreferences in routing patterns. :)
It was a joke...
I struggled a long time trying to get past all the matrix math that the usual Kalman filter tutorial starts out with. KF's make a lot more sense if you start from an example. By the end of the example, you realize that matrix math simplifies the notation hugely. But without the intuition about what it is doing for you, it doesn't help much -- at least it doesn't help me much.

So... my over-simplified touch-stones for KF's:

1. Everything is a Baysian quantity -- a mean (best guess) and a std. dev. (confidence).

2. You have a model of the system state.

3. You have some sensors, and you have some model for the accuracy & precision (noise) in the measurements.

Now, two rules:

1. The model runs open loop and at a regular cadence: "Tick tock, tick tock, the model updates on the clock." Of course, since you are running open loop, your confidence in every value of the model gets worse with each iteration (std. dev. grows). How much you adjust (reduce) the confidence is based on the precision of the system and the control inputs.

2. Sensors readings are applied as they come in: "Use'em if you got'em."

So.... now the moving average part... if you are twice as confident in your current estimate as you are in the reliability of the new measurement, do a weighted average of 2/3 of the current estimate and 1/3 of the sensor. This is why the confidence is carried along for all state values and sensor readings. Of course compute the weights of the moving average according to the current confidence values with every update.

And that is about 103% of what I know about Kalman filters :)
I haven't actually checked if firefox was eating my CPU but with my pre-quantum profile on post-quantum Firefox (connected to firefox Sync) Firefox would essentially lock up whenever I was on a page with a lot of Canvas stuff. I made a fresh profile and the issue was gone. Don't know if this is at all related to what you're collecting.
Yes, TLS termination is something that people get wrong, but there are other ways of decreasing that risk than to hand off the task entirely to someone else.

And yes, if AWS were compromised, that would suck. But right now a lot of CloudFlare sites are backed by AWS. So now their traffic is at risk in two places, not just one.

I don't tend to use cloud providers, no. I self-host some stuff out of my house, with reliance on DNS and CAs being the major points of "correlated risk". I use S3 for serving some public files.
>No good-faith participant in public policy debates aims to push whole generations into debt

I agree, but I don't agree that even a majority of participants in public policy debates are acting in good faith. I think it's possible, but given the results and empirical evidence we have to the contrary you should provide some evidence or argument to back up this extremely controversial claim.

I don't think they actively wish to push generations into debt like mustache-twirling cartoon villains, but I do think they are not particularly concerned with this side effect of their other policy goals which are essentially a massive transfer of wealth and power to the private sector, like, e.g. privatization of the loan industry and education.

>I think that argument assumes a whole variety of facts not really in evidence.

The original argument was made by Blyth, who is a serious academic, not me, and you haven't made any attempt to engage with him at all. The crux of the argument is that "anti-austerity is the cure to the ills of austerity" which is honestly nearly tautological because of its obvious correctness, not because of a flaw in its reasoning. It's natural to look back at similar historical situations, like a gilded age of massive inequality and the destruction of working class power preceding a depression. The only real difference between then and now is that we've chosen to call our depression a recession, and pretended there was a recovery from it instead of creating one.
JDCC: What Makes Winning and Lasting Companies
I was going to say something like this, except without the assumption that what we have today would exist. For all the concerns about walled gardens, I can still link to a Facebook post in a Slack message and vice versa. The hypothetical non-web-world would probably consist of Compuservs and MSNs, with very limited notions of links.
Has there been any effort to objectively measure the supposed centralization of the web over time? Although I've no doubt it is happening, the article doesn't seem to provide any hard evidence for the claim. Interesting to think about how to do it, e.g. you could measure clustering in the global page rank graphs over time, but that wouldn't incorporate info about Facebook etc.

3 reasons why static analysis tools code may be useful for embedded developers
This was in compliance with a court order. I, for one, am still relatively appreciative corporations can't go around willy-nilly refusing to obey legal orders from the government.

If you have a problem with specific orders of our government, the correct avenue of upset is with them, or, should they be unwilling to change their position, by voting.
I get that this is easy, but there are 2 main cons:

1. It is $4 a month (that's a lot for a really a simple static page)

2. Vendor lock-in. These sites come and go and might not be around in a couple of years.

This is why I recommend Hugo hosted on netlify. Sure, it has a learning curve (but plenty of open source themes make it fairly easy).
Hugo spits out plain HTML so there is no lock-in, and netlify hosts for free. If Netlify goes away, I can host somewhere else.
> I imagine other cities would impose similar restrictions.

Imagine what you will, reality still exists. Some places have similar restrictions, some don’t - there are helipads all over Los Angeles for example.

A safer, quieter ‘air taxi’ is more likely to reduce restrictions than add to them.

I don't know about you but I don't own a piano. I do have several computers though, and they all have a soundcard. Dynamic tuning is a problem that can be solved by software!

I'm fine with equal temperament dominating, but it shouldn't be taken for granted as the only system for selecting an intonation. When I went to school for music the only time we talked about intonation was in music history. I'd like to change that.
We could push for a signing regime. Every page has a certificate applied for every individual developer who worked on the page, and for every publisher whose content is on the page. Then the browser provides a simple button that will blacklist the developers and publishers from ever getting content onto the user's screen again.

Users can opt in to a sharing service which consolidates the blocked certificates across multiple users. When a threshold is crossed for a particular certificate, that certificate can be propagated broadly to all the participants in the sharing service and said developers and publishers can lose the ability to put anything onto a user's across wide ranges of users.

I think when people start having things to lose, they might start acting more responsibly and respectfully.
An army officer once gave me an amazing rundown of the ways deployed units have to recreate so many layers of infrastructure we take for granted. Military units really have to carry a whole version of their civilization with them, and how long they can maintain it determines their effectiveness (which is why most of military history is about logistics improvements creating newly dominant forces).

The challenges have a lot in common with space travel - not surprising that 3D printing has spurred so much imagination on both sides.

Side note: there's a quote in the article where Gen. Walters is envying what young engineers can do with this stuff. That's one of my favorite signals for tech that's not hype -- when it makes successful pros wish they were born a little later.

Bluegrass is a music style originating in Appalachia from the Irish, Scottish, and English influences of the area...

Also, heavy African American influences - a lot of music historians source the banjo to Africa, and African American string bands were very common and were a big influence on bluegrass and what we call "old time". If you're into bluegrass and old time, check out the Mississippi Sheiks. For something more current, the Carolina Chocolate Drops are pretty awesome.

Oh one other thing (man, really don't mean to seem too critical here), imperfection is very tolerated in a bluegrass group ;) You don't have to pass on a solo if you're worried you'll make a mistake, go for it. Better to go for it than hold back too much.

Just don't play over other people, be cool, listen a bit. You should have a basic competence, if not, probably practice a bit more and join a beginner or slow jam for a bit. But especially in a casual jam, seriously, take your break, it's cool.

is there any reason not to consider the deist view and say the universe was created with the cosmological constant needed for life to form as an equally likely outcome?

Occam's Razor.
I've been doing that. The problem is when users' IP get challenged by CloudFlare the assets will not load, even with security level set to essentially off.

Even assuming a multiverse explanation doesn't exclude a deist view. It just kicks the can down the road to one more level.

That’s exactly right - new measurements (observations) or state predictions (estimates based on the assumed system model) are weighted based on the ratio of the standard deviation (uncertainty) of that observation/measurement to the historical standard deviation of the model to that point in time. For the closed form equations of the KF to work, you have to assume a) all measurements and parameters in the state model can be approximated by normal distributions with known standard deviations and means b) the underlying system model is linear. If you can’t assume b), then as the author mentions you can approximate the non-linear model with a linear one by taking the Jacobian and evaluating it at each step, and use the slightly modified EKF algorithm to bring everything together into an estimate of the system’s underlying state.

As an aside a nice property of particle filtering (a different approach for localization and SLAM) is that there’s no linearity assumption. A nice property of both particle filtering and the KF/EKF is that the Markov assumption holds. This simplifies the underlying mathematics, as well as benefits the implementation on a computer by reducing time and space complexity required to evaluate the algorithms at each step.

"These type of posts"... Posts on incredibly important topics with incredibly active discussion?

I haven't seen one flagged and treated like this since 3 months ago (https://news.ycombinator.com/item?id=15745363) - but that's the problem isn't it - we don't see them because they've been flagged.

As I said then, a little transparency isn't too much to ask for a "Hacker Community". And it's really weird how my comment is compressed, even in new browsers, despite having 11 points.
I totally agree with this assessment.

This is the reason lots of people learning programming try few months of Javascript/Ruby , then they got stuck to solve any real life programming problem.
The reason is that they have not mastered the "basic core concepts" of programming such as traversing an Array backwards, nested loops, two indices one activates after another ete..

Reminds me a bit of SabreCMS, despite the options being much more limited. And Sabre allows a full export of your entire site/shop/landingpage in case you want to self host after building - And it works with all browsers which seems to be an issue here. But nicely done.

Such evidence as I'm aware of points in the opposite direction: HN without downvotes would be like a body without white blood cells. Disease would quickly kill it.

The problem with your argument is that it doesn't reckon with just how lousy bad internet comments are, or how many of them there are, or how completely they take over if allowed to. To a first approximation, bad internet comments are the entire problem of this site.

It's easy to imagine an HN that would be just like the current HN, only with some negative X (e.g. bad downvotes) removed. Most of these ideas are fantasies, because the thing you'd have to do to remove X would have massive side effects. You can't hold the rest of the site constant and do that.

Yeah, I think my big take-away from this document is: If you're going to have a CoC, you'd better be able to stand by what you say in it. Don't just copy-paste from someone else's and thereby unthinkingly overpromise.
Wow, that video was much better than the book in my opinion. The book spends chapters and chapters repeating the exact same thing over and over. And then the last third of the book is about divine inspiration and other things I just couldn't get into.

I always thought the book would have been better as a blog post or two, but the video format was perfect. It presented the ideas and gave advice on how to achieve them. I took a lot more from that video than I did from the book.
Note that the definition of "Block 3rd party cookies" in Safari is different from the one in Firefox (not sure about Chrome). Firefox blocks a lot more stuff when that option is enabled in Firefox than Safari does when its option is enabled, which causes more web compat problems.

Silverlight didn't really thrive though...
Not really. I gave up Firefox (as my main browser; I'm a web dev so use all of the major ones regularly anyway) because the main thing keeping me there was its extensibility, and that advantage went away. Firefox was and remains slower, less reliable, and less capable than Chrome, and IME has actually become worse in those respects as well since Quantum.
