Convolution is a correlation with a reversed signal.

Correlation is a generalized dot product: multiplying corresponding pairs of values from two signals, and then adding the factors together. The result is zero if the signals are orthogonal (like the dot product of two vectors in 2D or 3D that are at 90 degrees).

The intuition behind the reversed signal comes from processing in the time domain. There are application in which we convolve a new signal with a segment based on a captured historic signal. That function is reversed so that the newest sample from the new signal correlates with the least recently captured sample in the historic signal.

For instance, we can use an impulse signal (like a clap) to capture the echoes from an acoustic space. That signal can then be convolved with audio data in order to give it a reverberation similar to what would be produced by that acoustic space. The captured impulse response has to be reversed, because echoes come in reverse. In the impulse capture, the longest echo is found on the far right. When we apply the impulse to simulate the echo, it has to be on he far left, because it has to correlate with an old sample of he input.

E.g. if we are at t = 0, and want to hear the 500 ms echo, that echo corresponds to a past sound sample that is now at t = -500. When are capturing the impulse response, then we issue the gunshot or clap at t = 0, and the 500 ms echo comes at t = 500.

The earliest reflections have to apply to more recent signal, but they are based on the least recently captured data.
>Also, people seem to think the virus magically stops at an invisible 6 foot distance whereas in reality you need much more if you're breathing and running where you leave a much bigger trail of aerosolized particles as you run, and there's also wind carrying your breath much further than in a still situation.

But people also think (without evidence) that momentary contact closer than 6 feet is enough to spread COVID. It's almost certainly not.

You are very very very very unlikely to get COVID passing by a person for 2 seconds without wearing a mask. The infected person would have to sneeze directly into your mouth or something.
I love this game! Great rec.

"I'm surprised that you think that too much legislating is the problem."

Too much "legislating" is indeed _the_ problem. At least with gridlock they can't screw things up worse than they are.

Just look at AB 5 in CA - tailored by labor unions with all sorts of collateral damage and unintended consequences that are still reverberating through CA economy. What's hilarious is that many independent tech writers who were in favor of it initially suddenly got to find out the wisdom of our legislators first hand when AB 5 proceeded to destroy their current business model as an independent, for higher worker.

Ha! Delicious irony indeed.

Making new laws _should_ be hard. It also would be good if congress started to do their job instead of delegating it to the executive branch. And for every new hair brained law it would be awesome if they were required to at least remove one other one - removing five would be better still.

If you think complexity favors you vs. big businesses or special interests....
No, it's all degrees of risk.

The only accurate way is to quantify the risk, rather than blindly assert "extremely obnoxious behavior".
I had chronic migraines so bad 4 days out of every week I could not drink water or eat food. I'd puke from the pain. I could barely think straight and in the rarest of situations my mind would pass out from the pain.

Migraine medicine and other kinds of medicine I was given did not work at the time, so thinking they might be cluster headaches I turned to 4-aco-dmt, which is psilocin without the psilocybin, so no stomach nausea, but a bit weaker. It didn't stop a migraine once it had started, but it did work as a preventative. I did a little bit larger than a microdose once a week and had no pain, no migraines, no problems, for quite a long time. (A regular full sized dose I could take once every 12 days without migraines.)

I turned to 4-aco over mushrooms, because it was legal at the time, and no nausea. I believe it's still legal today, but I haven't kept up. Today, mushrooms are legal/deregulated in parts of the US, including where I live, so it's less of a concern.

Today I have a prescription medicine that works. I'm cognizant of taking a single drug for too long. When I look up what I'm currently taking (sumatriptan) people online complain it stops working at 7 years of use. This is great, because now I feel comfortable taking it for 5 years before needing to switch. However, the second I start needing more to function, I'm switching it out. I do not want a life long resistance. That needs to be avoided at all cost. When I was taking the 4-aco I was a bit more cautious, because I can't find online how long it works for migraines. I would rather keep it in my back pocket if I ever need it again, so I went off it the second I found a prescription drug that worked, despite that the 4-aco worked better.
looks wonderful, though the experience seems more like moving through a world than infinitely zooming (i.e. what feels like it's changing is the camera position rather than the scale)
Okay, this thread is making me nervous about Heroku. I'm building a web app that runs on it and I clearly have not given the pricing scaling as much thought as I apparently need to.

My site is a firebase powered SPA, so the only thing Heroku has to handle is the initial pageload....I would think that the standard 1x dyno would be sufficient for that....which is not very expensive...

Yes. Not on par with a gun, but that's not what you asked.
Since those reviews were posted, Wyze has actually enabled support for RTSP, which would address some of the issues those reviews mentioned. I haven't tested it out myself, but it seems to be working for a lot of people. I'm not sure if it still attempts to send data back to its own mothership though.
Yea that's what I came to realize for my bootstrapped SAAS. Can't offer the big bucks so decided to forget about hiring senior engineers for now and just focus on hiring smart/hungry/motivated/coachable junior engineers and slowly grow them into the lead role.
Quickly googling, here is an estimate that annual shoplifting value is 15-20 billions.

Should be quite easy to find data on this because companies probably research it a lot - might be skewed ofc.

This is a lot more complex than I expected.

I personally just use one ore more VPSs on DigitalOcean, which scale pretty well at first and if you get enough traction to need "infinite" horizontal scaling, it might be better to only focus on that once you have the money to hire some sys architect/admins.
I've been a Scala programmer for close to ten years now, and I've been shocked at how blithely people will 1) unilaterally commit their coworkers to enormous learning curves, without regard for the consequences, and 2) use crucial projects as personal learning opportunities, again without regard for the consequences. Partly it's self-indulgence, partly it's machismo, partly it's a sincere desire to build the best thing possible, but whatever the motivation, it can cause a huge mess. People need to feel responsible for leaving a certain ratio of polished, mature
code to beginner, learning code, even though that means that (gasp!) they can't live in a permanent state of learning big new things.
I do invest in both.
More like writing C properly.

When you program in C, you should know exactly what each byte of memory is for. If you don't do that, not only you will eventually get crashes and leaks and overflows, but you also miss the point of programming in C in the first place.

C is fast, but C is not fast because it overclocks your CPU or whatever magic you can think of. An good reason why is is fast is that it gives you tight control over your memory. You can reuse buffers, size them precisely, allocate them exactly when you need them and free them when you are finished, nothing funny happening behind your back. It generally results in lower memory usage, better use of cache and therefore better performance.

If you don't manage your memory precisely, then sure, C is probably not the language for you.
The issue of EV batteries reigniting after a crash seems very solvable...

For example, every battery cell could have a built in discharge circuit. Whenever the cell no longer received a signal from the cars computer indicating "the car is healthy" it goes into failsafe mode.

Failsafe mode consists of every cell discharging to zero volts through a PTC resistor to keep a constant temperature of 150 degrees C. That will discharge cells as quickly as possible while avoiding starting a fire.

If the vehicle cooling system is functioning, the whole battery will probably be discharged in 30 mins. If it is not, emergency crews can spray water on the battery and it'll be safe as soon as it's cool. Or they can not spray water and know that it'll stay at a constant (hot) temperature, but that thermal runaway isn't possible due to the PTC heating.
Who controlled the RTLM? Who financed it? Who created the propaganda? Who placed it on the air?
To clarify, Pulumi does not use Terraform - it simply uses the CRUD operations from some Terraform providers. The core of Terraform is not involved.
Are you aware that Apple hardware pre-2015 was much more open than it is today? I agree with your sentiment for modern Macs, and that's why I'm trying to find a suitable OS for switching.

When there's a limited scope of what drivers are required, it should be easier, not harder, to support certain hardware. Being unable to read NVME drives (which have been around since 2011) is no longer acceptable for an OS in 2020.
To be clear, Sectigo was split from Comodo by PE. They are separate companies.
The CEO at Comodo who did the LE trademarking attempt hasn’t been a part of Sectigo and the CA for 3 years. Sectigo have also worked with LE and helped to sponsor the CT log they operate.

It may not change your opinion, but it’s important to be aware of the details.
Thank you very much for this feedback. I will try my best to improve that!
Could you show us an instance of RMS being "actively supportive of pedophilia"? This is a claim that will both ruin a man's career, life and reputation, so you better have some decent sources.
I extracted the inner text inside a <p class="foo"></p> using Python & BeautifulSoup, print to stdout, then cut, sort, uniq, and sort again.

It looks like the counts from this voodoo are incorrect: they are all twice as much. However, proportions are still correct.
Another neat trick is to use the 8GB Raspberry Pi 4 and load the whole OS into the RAM at boot time. This makes booting take much longer but after that the system runs very fast and responsive.

Of course eventually the logs will eat everything to you have to write back to USB or SD from time to time.
One thing that flatpak has over nix is the set of common bases. If I was going to distribute something shifted from nix, I'd essentially need to move every single dependency (which needs to be compiled/configured right). It's not a huge problem for a cli tool in golang, but something that requires qt, GL, input method support, etc.? I'm glad there's a flatpak base for those that not only "just works", and it's going to be maintained/distributed even of the app isn't.
I misread it as Zoom Quit and thought it’s going to be the monthly Zoom bashing thread.
Someone within US jurisdictions ought to be liable.

As far as I can tell, that's the company who imported and sold it. If Amazon and Walmart are liable, I won't need to worry about fake Sandisk memory cards, fake medicines, fake clothing, and other fake products there.

I'd love that.

Maybe I just had a really bad 6 months with Amazon, but it seems everything that comes is a fake or a scam.

I'd gladly pay 10% more for real products than 10% less for 50-50. Right now, I switched to mostly buying off-brands direct from China for a lot of products, since I get the same thing as Amazon, but at a lower price and with an honest label.

Or buying direct from manufacturers if I want something real.

I got screwed once doing even that, though. I ordered a brand-name headset. They did... fulfillment by Amazon. The headset is barely usable, so I'm assuming Amazon did commingled products. Or perhaps I got a defective copy. In either case, not worth fighting for 50 bucks.
Which brings us to the frequently-on-hn topic of manufacturers loading up tractors with DRM crap so if it breaks you or the neighborhood shop can't fix it, you have to take it to the official dealer shop. Good luck booking a slot there during harvest season.

But yes, maybe slightly old machines are the solution rather than spending a lot of time and money to keep ancient rustbuckets going.
FWIW, I disagree with GP. I'm more productive in React than in SSR, and I'm much better at code design and architecture with it. React is pretty much old and boring by now.

Just build in what you know.
Anyone doing research on the effects of nicotinic acetylcholine inhibitors mixed with psilocybin? That seems like an obvious avenue for exploration, given we now know that they naturally occur together[1], but I haven't seen any papers on that yet.

Occasionally it is also useful to have something written that I can point to when I am making the same argument again. But I agree that primarily it is for me to practice my writing. I have a couple of readers, and a couple of popular articles but I just enjoy messing with the tech around deploying the blog and practicing my writing skills.
I think you might be mischaracterizing the views of those you oppose. If you dismiss concerns about censorship as being about neo-nazis, you're missing the larger point.

The ability of private corporations to suppress ideas in social media is unprecedented. If FAANG, Twitter and PayPal get to determine the bounds of acceptable discourse, how do you know it's going to go the way that you personally approve of? What protects your speech?
The radio station operators or the journalists and bosses who created and put the hate material on air?

That's fair, and I should check myself. I got so caught up in everyone's solecistic discussion of causality that I missed the line in the paper where they specifically disclaim that this is a causal association.
Not to bring computer science into this, but in any system the chance for corruption increases with both size and complexity. New Zealand, while I'm very fond of it and a great admirer of it, is pretty small and notoriously hard to immigrate to.

I was introduced to convolution in a undergraduate signals/systems course in continuous time where it's basically magic that you memorize to pass your course. I think a better introduction would be through discrete convolution by reexamining polynomial multiplication (which is convolution through a different lens - the coefficients of the product of two polynomials is the convolution of their coefficients).

That serves as a less magical introduction to the operator. You can then point out that the polynomials whose coefficients one convolves can be considered power series, which has a nice interlude into the Z transform and its usefulness as an analytical tool when working with convolutions (and then on to the Fourier transform, etc).
It loops after several of those paintings, or about 5 minutes
There still isn't a good alternative model.

Without ads, businesses will put up subscription-only features and paywalls. People hate those too. But we need to accept the fact that businesses can't make money by giving everything away for free. I'd rather put up with ads than see the internet devolve into paywalls on most sites -- paywalls are more annoying to work around.

I just experienced those! In March I was flying MUC->SFO (the day before Trump "closed the borders", lucky timing for me). Due to COVID the plane had been downgraded from an A380 (which I was excited to try out, since I'd never been on one) and instead was a smaller Airbus which was also new to me. First time I went to the bathroom I was totally caught off guard. No idea this was a thing, had never even heard of it.

So novel that I took pictures to show my friends when I got back in the ground :-)

50 Years of Gaming History, by Revenue Stream (1970-2020)
The story is unfortunately complicated, so many news outlets get it wrong. myPersonality was my app that ran from 2007-12. Michal and I published papers based on its resulting data, which was collected with user consent and only from users who used the app (not their friends). We worked in the Psychometrics Centre - a research group in Cambridge University. Prof. Kogan joined Cambridge University later on in 2013 as an independent faculty member not in the Psychometrics Centre, created his own app 'mydigitallife,' and went on to work with Cambridge Analytica using data from users of his app and their friends.

So key points from my perspective are (1) My app isn't the same as Kogan's app, (2) I didn't work with Cambridge Analytica, (3) Kogan was independent faculty, not part of the Psychometrics Centre.

As you've noticed from my post history, I don't usually use this website. I do, however, have an alert set up that pings me links when someone uses my name online. I have it set up so that I can attempt to correct journalists who write about me and my research group and get the facts wrong.

Hope this clarifies things

Edit: Since I'm here. I think it's critical that NYU's Ad Observatory continues and that academics have freedom to collect data and report results that might embarrass rich and powerful companies. Tweet #9 in this thread is the key one ( https://twitter.com/doctorow/status/1329873620353515520 ) - how do we know that FB's own ad library isn't good enough? Because Ad Observatory found that it wasn't reporting all instances of political ads.
You don’t think the British and the Americans had any blame for this? For why China was so poor, and had to dig themselves out of a hole in the ground?

After all, the criminal British Empire made their fortunes, by shoving opium down the throats of the Chinese for 100 freaking years!

And then Franklin Delano Roosevelt, who never had a job his entire life, and just one day became the American president, well, where did his family get their money from? Yes, that’s right. Opium. The Delano’s were also the biggest American drug smugglers during the opium era. And yes, when the Americans were talking about trading success with the Asians, they were specifically referring to opium, but they were too ashamed to admit it.

The Chinese opium era was the greatest theft, and the greatest transfer of wealth in human history!

Google it man. Educate yourself about the sins of the British and American empires.

At least after the CPC and Mao came into power in China, they finally eliminated the opium scourge, and kicked out the British dickheads from their country (except for Hong Kong).

I use large doses just for fun. It is great. Haven't had migraines either, I think I will keep using just to prevent the migraines.
Yeah, this is exactly why I'll be buying used pretty much forever. Don't trust self-driving anything, don't trust wireless/remote start, don't trust half-baked services like OnStar... if it gets to the point where ICEs are outright illegal, then I'd sooner convert an old beat-up Tacoma or 4Runner to an electric drivetrain than buy new.

The only exception is if I have full control over it, including the ability to lock it down. No OTA updates; if I want to install security patches, it'll be through Ethernet or USB or some other wired connection. But preferably, there wouldn't be a whole lot of software to update in the first place.

I've been using youtube and google products in general for a long time and only recently have been breaking away, but I'm sure that that has somewhat helped.

A close friend's father uses Psilocybin to treat cluster headaches. He dealt with these debilitating headaches for a long time, basically unable to function as a normal human. This is in the US, and he is a former small business owner (retired), with money, and was able to see numerous specialists, attempted many treatments, all of which were unsuccessful. I'm not sure how he figured out that Psilocybin is an option.

Psilocybin is the only thing that relieves his cluster headaches for months at a time. I believe he doses 3ish grams of dried mushrooms, once a day for 2 days. I hope this gets more attention now that some states are decriminalizing Psilocybin. I suspect that other substituted tryptamines would be helpful as well, without needing to digest lots of mushroom fiber (which can be hard on the gut unless you fast for a period of time before consuming them). 4-HO-MET and 4-AcO-DMT comes to mind.
wow, pretty amazing post
