I wasn't familiar with Kalman, and I tried to understand it by reading the primers on this website and it wasn't clicking for me. Last night I was thinking about the sample graphs, and it occurred to me that it just looked like an Exponential Moving Average, which is a much simpler concept to grasp.

I just searched Google for a comparison and found that EMA is as good as Kalman for "random walk plus noise" on a Stats Stack Exchange, and that a 2003 paper from Brown University (Joseph J. LaViola) showed that a Double Exponential Smoothing algorithm is of equal quality to Kalman (and extended Kalman) but 135 times faster, and a simpler approach.

I find Double Exponential Smoothing to be much easier to understand than Kalman, and assuming the LaViola paper is correct, I'm not going to put additional effort into understanding Kalman.
Reminds me of how restaurant chains get bought out, and the menu's "optimized" for the best sellers only. Cutting ingredients that are used in the niches. Narrowing in on the stuff that sells the most only. Until all that is left is the same thing you can find in any of their competitors. No differentiation left. Followed by a slow death spiral towards closure as the race to the bottom leaves only one store of type X per area, the one that has the best lease, or can cut the most corners and crush their workers the most to squeeze a slight profit advantage.

Wow, I did a double take in your second paragraph thinking I was reading a comment I had left earlier, lol.

But right on, I feel exactly the same. I do plant transformation and we call these experiments, mRNA "transient-expression" assays, as in, transiently transgenic. It was so weird from my perspective that we were going to start using the common lab technique to test genes on people.

The only two facts I needed were that over 80% of people that have had COVID never even knew they had it, it's that mild. And of the people that even show symptoms it have over a 99% recovery rate.
They are no more or less vulnerable than anyone else. When a company does cuts they usually do so in a vertical slice. ICs, managers, even executives are all affected on a proportional basis, because the company will want to continue to maintain its management ratio. Being left with 30 ICs in an org with 1 manager or 5 managers with 10 reports are both non-ideal scenarios for the company after a layoff.

Anecdotally I can say that experienced engineering managers with a good track record are significantly more in demand in the industry than ICs.
Maybe not with just a single regular disc, since those require hardware owned by a shrinking group of people who might impulse buy a DVD. But I wonder if it would be worth it if they were "collector sets" or something, maybe with a digital download, and some extra stuff in a box. (Art books, posters, etc) I feel like you'll actually get a few people impulse buying a 100$ set, vs a 12$ DVD.
If my setup is secure enough that someone has to break SGX on my laptop to beat it, that's good enough for me. What is your threat model anyway?
> an ip address for every grain of sand in the universe

https://en.wikipedia.org/wiki/Observable_universe estimates 10^53 kg in the observable universe.

10^53 kg / 2^128 = 10^14 kg per address, though I have no idea what fraction of the universe is sand.

In practice, the number of allocations is much smaller because IPv6 is effectively a 64 bit address space, with the second half reserved for edge networks.

Somebody is doing something similar to my Chrome extension. They stole the (minified) code, slapped their own logo on top of it and started selling it. I filed a DMCA takedown request at Google and they removed the extension. Then the guy reuploaded the extension again with a slightly different UI. But I can still see that the underlying code is all mine!

I don’t particularly have a claim other than you can’t use minimum wage causes inflation as an axiom because it is theoretically contentious and doesn’t hold very strongly empirically.

The claim that it lags behind the wage change is empirically also not found.
I wouldn't say they are too hard, there are any number of physics problems that are 'too hard' in the sense they would burn all the matter in the visible universe to answer.

There is a similar kind of anti-scraping technique, where you serve fake data that looks very realistic, but a part of it is modified in some way that renders it useless.

Of course the challenge there is good bot detection to not accidentally serve fake data to a legitimate user.

I understand that streaming is a great option but what about high quality? I buy Blu-rays of media where quality is a high point of the experience. Things like Pixar films, traditional animation, films with extraordinary visuals (e.g. LoTR).

Are there full-quality digital/downloadable options that I'm not aware of?
probably yes. although that's a bit of an article of faith. in analogy, I wonder how much progress and innovation, and general world progress, has resulted from opening the internet to include Russia, for example. Sometimes including actors that do not conform to certain ethical standards and trust worthy behaviors, leads to spreading infection and danger to the world.

Another analogy: Incorporating cancer cells into the body rather than sanctioning their growth, is a sure path to death.

this is not a directly equate China to cancer, especially the Chinese people to cancer. That's clearly incorrect. however, I do think it is correct to expect our trading partners to eventually establish trust with each other, on the geopolitical sphere, and if that fails to appear, it makes sense to diversify our strategic resources and partnerships
Yes.
My reasoning applies to a function n=> BB(n)

Calling it 'very basic' actually exalts the concept of code reviews, because the ideal code review is more than just identifying bugs in the code under review.

I had a dream once, in about 2000 or so, that I was touring a "smart home" that featured display panels on the walls, cabinet faces, etc. that could be reconfigured to display whatever you wish: flowers in the spring, foliage in the fall... a complete change of décor at the touch of a button.

While I was touring it, the smart home was hacked. And suddenly... goatse. In every room, on every surface, that same gaping orifice.

I woke up sure of one thing: Smart homes... not even once.
I never downvote and almost never upvote. Having spent time on 4chan and other imageboards, I have seen discussions work just fine without any ranking mechanism, and as such I have become skeptical of the usual upvote schemes.

When there are no ranks (or even usernames), you need to use your own thinking to evaluate the posts. Even if it requires more scrolling, it's worth it. If you are looking for the hot parts of the discussion, you can use the number of replies to a given post as a proxy — it could be considered a UI issue of HN that it's not shown very clearly here.
Yeah, copyrighting the descriptions seems fair to me. It's not an identifier but rather a creative description of the talk. (I feel like most speakers would want their abstracts distributed far and wide, but obviously AWS feels differently.)

I suppose at the end of the day, everyone receiving nastygrams could have a contract with AWS that prohibits disclosing the names of talks at their conference. That is a shitty condition to attach to a cloud service and should not be legal, but it probably is. (I wonder what speech conditions I agree to for receiving electricity at my house. I've never checked.)

At most bigcorps your manager can’t unilaterally fire you. There’s a whole HR-driven process. And if your work is measurable they are probably doomed, which is much easier to achieve as an IC. (Obviously this excludes things like violating laws or policies)

Plus the chance that managers 3+ levels up know or care about it you is minuscule. As a VP you have much more visibility. If your org does poorly you can get fired quite easily

Gundam: Hathaway is interesting; maybe not quite as disciplined as an Oshii outing, but it happily surfs the intricately constructed wave of UC worldbuilding.

Not an anime, but I recently watched a playthrough of the Project Wingman DLC, Frontline 59. It is admittedly the polar opposite of TFA, but if you go in with no knowledge of the original game's story and lore, like I did, it turns out to be decently challenging, thematically. Literal Pyrrhic victories abound.

Something completely different: Odd Taxi. Again, best to go in without any prior knowledge. Just vibe with it. Like Psycho-Pass, it's an encouraging example of the quality of stories you can have when someone who doesn't usually make anime makes an anime.

You should look into overpolicing and how it impacts those summary statistics; in brief if you look you will find someone breaking a law but bad behavior in one group gets ignored as an exception whereas in another group each incident is treated as emblematic and needing strong corrective action.

In my experience both groups are full of pretty similar young men, which makes questions like yours pretty obviously loaded; why are you expecting one to be measurably different?

I guess it is the difference between measuring the size of a set, and labelling the elements of the set with a number. Both can be called "counting", but the meaning is different. The first of something should always be labelled 1, but obviously the empty set has size 0.

That's the main problem I have with using ℕ for {0, 1, 2, ...}. It's easy to get into the habit of writing stuff like x_0, ..., x_{n-1} for n elements, and that's just ugly. x_1, ..., x_n is much better and clearer. On the other hand, 0 is useful when it comes to measuring the size of something (an offset, for example, or age).

I think ℕ and ℕ₀ is a good way out of this dilemma. ℕ is the natural numbers, and ℕ₀ is the natural numbers with, well, 0.

The other way out of this dilemma is what most here prefer, I guess: It's to say a label is just a label, and starting with label 0 when labelling the elements of a set, is just as good as starting with label 1. Then you just need ℕ = {0, 1, ...}, and ℤ for the integers, and you will not have much use for ℕ⁺ = {1, 2, ...}, because now sizing something and labelling something is one and the same. So you will now use x_0, x_1, ..., x_{n-1}. So you start counting from 0. I don't know, I just don't like it, but in the long run, maybe it is less confusing, because you unified the concepts of sizing and labelling, and now you can call both of them just counting.

If the site is for fun and doesn't make money, then how is what these aggregators are doing considered "theft"? Theft of credit for making the app, I guess? I dunno--I'm surprised the article OP is so bent out of shape if it's just a fun throwaway project. I wouldn't care but maybe that's just me.
Oh I love stories like this - great retort! It reminds me of that time that some app (or apps) was hammering an image of a butterfly from Wikimedia because it was part of some sample code that was never removed.

Perhaps there should be some form of register for police, that tracks officers dismissed, or who resigned to avoid termination, etc., so that cities and departments could use that to inform hiring decisions.

Oh, wait, there absolutely is such a thing! That's great!

Except a large number (majority, even) of police unions around the country have it written into their CBA that this register cannot be used for hiring decisions... Well, shit.

I spent years trying to find the value others find in handwritten note taking. But it doesn’t work for me.

For me, listening carefully and questioning the speaker internally and focusing intensely on the way they are speaking and visualizing the concepts works better. Handwriting interferes with that as I’m too busy rephrasing to fit into my writing rate. My memory is better than the paper at the nuances of the concepts IFF I am intently focused at a semantic level.

I think, like many of these things, they speak to the average experience. That many people benefit from hand writing. But humanity so very varied, and there one size fits all analysis of learning style does really well at picking out the mode, but statistical analysis cuts off the tails and outliers as noise. But being the noise as an individual makes these sorts of statistical teaching methods painful and distracting.

The day I pushed the paper and pen aside and learned the way I learn best was the day school went from being a chore of tedium, a true struggle, to being a delight. I turned around from a barely capable student to getting highest honors from one of the science and engineering universities in the world. Further by honing my ability to understand deeply with just my ears and mind I can carry that into every day life outside a classroom, such as casual conversations or other formats where note taking would be weird. I’ve never missed my handwritten notes, and I literally never take notes and never will again.

Sure. A $15 controller to an OEM (made by Nintendo) is probably the biggest jump in quality that a regular person will notice. The aftermarket controllers often feel cheaply made, skimping on things like replacing the rubberized stick caps with hard plastic. I've seen controllers where the plug was just a couple millimeters too large, causing it to be stuck in the console port. The stick boxes often sometimes feel coarse and wear out quicker than they should.

On the upper end of the spectrum, OEM controllers from Nintendo are generally considered high quality, but in a precise game like Melee there are a couple things that can cause hangups.

The analog stick might not be properly calibrated. The controller reports the position of the analog stick as its x and y coordinates from -1.0 to +1.0 in both axes. Pushing the analog stick all the way to the edge should result in a 1.0, but some controllers instead report a 0.9875. Completely unnoticable for 99.9% of players, but at the highest level it can make a difference. Sometimes fixed by shaving more plastic off of the controller shell, but custom PCBs let you calibrate the stick manually.

"Snap back" is a more common issue. Tilt the stick all the way to the edge, then let go. Ideally, the stick would return to the center, but oftentimes the momentum carries it past the center into the opposite axis, resulting in a small input in the opposite direction. For some techniques this can have bad consequences, such as Falco needing a neutral input to shoot his gun, but a small input in the opposite direction will turn him around and shoot the gun the opposite way. Common fix for this is soldering a small cheap capacitor to the output of the stickbox's horizontal potentiometer, very subtly smoothing out the directional output.

Fancier mods include things like reducing the travel distance of the gamecube controller's large shoulder buttons to allow for quicker inputs or replacing the shoulder Z button with a clickier button.

This youtube video goes over a popular custom PCB that people have started to use in place of OEM, and some of the reasons why it is desirable: https://www.youtube.com/watch?v=RGyQbXGr4Po

If you just want a decent controller, finding a normal Nintendo-made gamecube controller at a used games store or ebay isn't that hard yet. Odds are it'll still be in decent shape.

If you want to buy a custom one, I don't know if I have any great answers for you. It's a pretty grassroots community, so depending where you live, your best option might be to scour facebook/twitter/discord to find your local Melee players and ask for the guy that makes/sells controllers.
> Are they just going to convert into another cellphone shop?

I think they're planning to convert their stores into more of a "showroom" type experience that supports their online shopping. They converted at least half the floor-space of our local Best Buy into a warehouse/online order pickup area. IIRC, the guy manning one of the cell-phone displays was actually a Samsung employee.
I think that if what you were describing was true, a federal DOJ investigation would result in a lot of people spending time in federal prison, and your friend walking away with enough money that your friend can drone all he wants from a private beach in the Bahamas while you both sip mai tais.

So yes, they can retaliate against your friend. And your friend can retaliate against them and the difference is that their retaliation will cost your friend a few hours and a few hundred bucks, but your friend's retaliation will put them behind bars and destroy their careers and probably imperil their pensions.

So if your story is true, contact the DOJ.
