In addition to gibsonf1's recommendations (not books), the following books are good. The first 2 are more pure introductions to the math, the third is applying it to physics, the fourth to CS.

Linear and Geometric Algebra, by Alan Macdonald: http://www.faculty.luther.edu/~macdonal/laga/

Vector and Geometric Calculus, by Alan Macdonald: http://www.faculty.luther.edu/~macdonal/vagc/index.html

Application to physics: New Foundations for Classical Mechanics by David Hestenes: https://books.google.com/books/about/New_Foundations_for_Cla...

Geometric Algebra For Computer Science by Dorst, Fontijne, and Mann: http://www.geometricalgebra.net/index.html
A more realistic taxonomy would be discrete (number theory, graph theory), continuous (geometry, analysis), and discrete properties of continuous things (topology, applications of analysis to number theory).

One of the reasons I deleted my Instagram account in 2017 was that their recommendation algorithm started showing me neo-Nazi posts. I suspect this was because I followed a bunch of motorcycle and custom/vintage truck hobbyist accounts. Turns out a lot of these IG bikers and truck bros were neo-Nazis. Definitely not something I want from my hobbies.
Google Hangouts is pretty great, so of course Google is discontinuing it. I always have email open anyway, so its very convenient to fire of a chat while I'm on desktop.

Dumb question -- how does this work with SSL? Is Apple putting their private keys on these boxes and assuming the ISPs can't/won't extract them?
I can't talk about the company as a whole, but in my circle at Arm reviews come from all the people who work with the reviewed. I did a review of my manager, requested by his manager.
If they cared about this problem to the exclusion of all else, sure. But Facebook doesn't want to ban all mention of Michael Bloomberg since Facebook users want to talk about him.
I love the old style of (personal) website like this. It's seems both nostalgic and maybe a bit more authentic.
I loved his rant about space heaters. He showed a bunch of different products, all the same kind of heater, down to having identical 1500W output - but they were rated for small, medium, and large rooms, with proportional pricing. He went on to explain some basic thermodynamics (as opposed to marketing)...
The relay attack is pretty wild but it also sounds like all these years later all these cars are mostly using an ancient cipher.

The Cipher was broken so badly that as far back as 2005 it was published how to break it, and it has still never been changed.

If you have regular access to the car (parking garage) you can just break the cipher if you see it on more than one day... no need to relay at all, and no protections against the relay attack would stop it from working.

It's a 40-bit cipher but because of a weakness you can calculate down to 2^16 possible keys and then come back on another day and break it very quickly at which point you've essentially got your own key to the car.
Never trust anything that comes from indiehackers, this is a community of professional indie astroturfers and manipulators of everything from renaming the same product and launching it every couple months on ProductHunt and buying upvotes, to baiting HNers with "How I made $X by doing Y". It's a pump and dump scheme on sub-million dollar levels.
Something I started messing around with: add a global stylesheet with the rule

body { filter: grayscale(100%); }

(only gotcha is position: fixed; elements breaking in Firefox?)

It feels a lot easier to focus on what I'm reading and to not be sucked in or distracted by websites. I bet psychologically color activates reward systems that may not be as healthy for digital content.

I actually liked it so much that I used accessibility options to make my entire computer and phone grayscale. So far it's great! Also has better performance than a CSS filter for stuff like video.

The "conspiracy" portion of my brain makes me wonder if it's possible that Apple phones have lower power levels if the location services determines that the phone is in a location with a known anechoic chamber. There can't be that many of them.

Such behavior has already been shown by automobile manufacturers during the "diesel-gate" incidents.
The article you linked to is from 2006; if a 30 year old technologist today is surprised by this, I don't think it's fair to say that they're either bad at understanding how technology affects society or liars because they weren't writing articles when they were 16.

More generally, people can grow, learn, and change a lot in a decade and a half, even if they were already adults at the beginning of the period. I don't think it's particularly effective to dismiss all current viewpoints of someone just because they happened to disagree with you on something 14 years ago.
(1) There's nothing messy about that graph. It's just two nested function calls. An exception by itself is just a goto to the catch block.
Republicans are also against more taxes, so increasing property taxes isn't very appealing. Plus, the Republican area of northern California (the "State of Jefferson" area) isn't very wealthy, so I think people fear they won't be able to afford paying any more money.

For error messages, they've apparently gotten much better in the Xcode 11.4 beta.

There's a whole new diagnostics engine in Swift which has been designed to specifically solve the kind of error ambiguity that happens all the time with the insanely-nested generic SwiftUI types.

Thanks for mentioning UnicodeMath. That does seems like a better fallback solution than raw MathML. It appears there's a newer version of the document you linked to that was posted on HN, by the way: https://news.ycombinator.com/item?id=14687936

I'll also look more closely at CSS Grid.

Okay you have my attention now.
Yes, that's what induced demand is.

In a vacuum, no, I don't think simply adding housing can meaningfully drive up prices. But (as you say) obviously it feeds into organic urban growth, which does increase demand, so you have to keep building housing. It seems that the problem we have in our big tech hub cities is that we let that growth happen for a while and then decided that there would be no more housing.

I can imagine an induced demand effect as whole new classes of people realize that they can actually now live close to where they work, and come flooding back into the city. But like I said, that's an artifact of artificially constrained supply.
There are probably many from 1950 - 1980 to choose from. I've read many science fiction books from that era where the premise was such a bomb (though the destination was different). I'm not a movie buff, but I'd guess there is a superhero blockbuster with that theme somewhere in there (
Superman?).

Guessing ISPs won't have access to the boxes in a way that'd let them extract them.
I'm fairly certain that is because "Active Major Construction" is a specific classification, and it does not apply to road construction.
No kidding. Already, I've found some interesting articles to read.

I'm taking a look at https://dwheeler.com/essays/easy-cross-platform-gui.html, which has references to XULRunner etc. which since 2009 have fallen out of favor.

Would you continue to recommend those wanting to invest in (for the 80% of use cases) wxWidgets for FLOSS cross-platform GUI apps? BoaConstructor et. al look interesting.

Thanks for taking the time to look at this comment. If it helps give you some context, I'll throw in that I currently am most familiar with WinForms .NET apps or very small Win32 native applications, and have avoided JS successfully so far.
That's an interesting definition of "major". Some of these permits are for projects like a 59 square foot expansion [1] of a single family home.

That's what I don't understand, increasing density usually means price / sqft for all real estate in the area goes up. I often wonder if the analysis on why people shoot down zoning changes is incorrectly attributed to price or property tax, and is mostly people resisting any change.

Note: I realize this response sounds similar to what you have already tried, but it's slightly different in a way that might be useful to you.

Background: senior year of college I took one of the deep learning courses my CS dept was offering, and I was nervous about it early on because I nearly failed the math pre-req test they gave to assess whether we could handle the concepts in the course and get some value out of it.

I ended up doing well in the course and passed with a great grade, even though I felt like I was drinking from a technical firehose the whole time. The technique I ended up using to get myself through was what I call depth-first learning. Basically you start from the beginning of a non-trivial, legitimate starter project or material, and work through it as you normally would. When you hit a point of confusion or a knowledge gap of any size, pause everything and follow the concept graph all the way down until you bottom out or hit something you have seen before and understand, then backtrack and continue from where you first branched. Taking notes in a gdoc or something is also crucial.

I'm not claiming to have reverse-engineered cold fusion or anything by learning this way, but my main takeaway was this: everything I thought was complex was really just a huge pile of simple things that I understand (or could understand with minimal effort). It was all about understanding the essence of what is going in the big picture and how the smaller pieces relate to it. The main difference I think in this approach vs what you have already tried is that you are using a similar approach with a reference manual, and not a legit near-state-of-the-art project with a concrete goal in mind. If you don't try to accomplish something specifically, you're just going to load up a bunch of information in your head, then eject it when you come across a problem you are actively trying to solve.
Disclaimer up front: I work for GM, I don't work on SDC.

As I see it, self-driving is a cursed[0][1] problem. If you could choose a different problem space, or to ignore some complications, self-driving would merely be very hard. But the requirement to handle ANY external behavior with ANY external conditions and navigate to ANY destination, while also maintaining safety is impossible* satisfy.

One cursed corner of the problem space is ML itself: ML is amazing in that it enables emergent behavior [3], but ML is terrible in that it gives rise to emergent behavior. The traditional engineering mindset wants a map of inputs to outputs, but you don't get to choose your inputs in the SDC world, and you can't specify all of your outputs.

Another cursed corner is the Always/Never[2] problem. You want safety features like Automated Emergency Braking to Always kick in when there is a problem, and you Never want them to kick in when there isn't a problem.

I really don't know how any of this gets fixed. I do think that sensor fusion and advances in AI can reduce the size of some of the cursed area of the problem, but the problem is also meta-cursed in the definition of Self-Driving: the solution to normal cursed problems is to reduce or change the solution scope, but if you reduce or change the Self-Driving solution scope, then "it's not real self driving".

From the article:

> It harnesses data to look for words or terms or emojis that point towards suicidal thoughts and immediately connect these individuals to counsellors to prevent loss of lives due to suicides.

The problem is that Clippy will send you to the counselor. You will get a generic notice, but the counselor will get the suicidal risk in big red letter.

Then the counselor will have a protocol, and send you to a real doctor, also with a hidden warning about the suicidal risk.

The doctor will also have a protocol, and put you in watch for a week just in case.

Where you see two thinking humans that may override Clippy, I see two rubberstampers that are afraid to make a mistake so they just follow the protocol.

I don't expect to see this here in Argentina, sometimes the barrier of the language and the cost is an advantage. But I expect to read a few horror stories about this form universities in USA during the next 10 years. Let's verify our guess in April 1, 2030.
It may be possible to place caches deeper inside an ISP's network than the peering points. For example, it looks like Apple peers in Dallas but not Austin or Houston so putting a cache in Austin would save bandwidth up to Dallas.
The people profit, not BART itself. BART is infrastructure. Like the fire department, it is not intended for it to be internally profitable.

The way the people profit is you put homes in the places that have lots of jobs, mostly so that people can just walk around but also to benefit from people filling up the reverse direction on BART. In places that have mostly homes you buld jobs instead. For places without an abundance of either, such as Orinda and Lafayette, you build both.

It's total nonsense that we build a railroad to a place like Lafayette, but that city has had the same population for 50 years. This goes triple for Berkeley, which has THREE subway stations and the same population it had in 1950! We should expect that adding billions of dollars of infrastructure also adds lots of people.
> The adaptive cruise is really good. It's camera based, and I have had zero problems with it. It works well at night and in pouring rain. It'll even stay pretty close to the car ahead of you if you turn the "tolerance" all the way down. I'm always impressed.

I checked, assuming it's actually using a radar - and you're right. They seem to use a stereo camera system. Neat.

Similarly, I feel a continuity in how old my website is, but in Ship of Theseus fashion lots of little parts changed over the years (and pieces were lost to storms, etc). I was really excited at one point to find an old time capsule of a snapshot from a particular redesign I recall being fond of around 1999: http://worldmaker.net/wmo99/

Amusing to myself and contributing to overall Ship of Theseus analogy, the current design is a responsive, flexbox-based recreation of sorts of the original goals for that 1999 site. I'd like to think the 1999 version of myself would very much appreciate it (especially after all the work in making corner GIFs versus the magic of CSS border-radius, and fighting TABLEs for layous).
You are not suppose to trust the media. We only think we should because they tell us to.

Logically why do we think they have our best interest at heart. Why do we think they are neutral and what they say is a fact? Why do we divide them into news and fake news (the labels change based on the view as to who is who)?
Turns out you can't make ridiculously complicated autonomous tech that interacts with the real world in an incredibly nuanced and varied way out of pure VC hype.
The best extension to do this is to run NoScript in temp whitelist only mode. Every time you visit a crappy website with lots of JS domains that load JS domains that load JS domains you'll have to spend 20 seconds load and reloading the page till you get it to work. If at all. It thoroughly discourages visiting these bad websites.

But good websites (ie, not web apps) will load instantly and unimpeaded. And as a side effect you're protected from most browser exploits since the vast majority require executing JS.
I maintain Planimeter's Grid Engine https://www.planimeter.org/grid-sdk/, which I also advertise as a 2D game engine. It also exists in the Lua ecosystem.

I'm sad to see Corona Labs shutting down. I'm happy it's engine will be open sourced.

There is some really great 2D game software in the Lua ecosystem, but hardly any of these products are actual engines.

Defold and LÖVE aren't game engines, they're frameworks giving you load, update, and draw callbacks and some bindings to underlying libraries. None of these solutions will load levels for you, or provide entities or actors.

Polycode is more of an engine than the former two, or even Corona.

I'm sad to see another piece of software slated for end of maintenance in this space, but I'm hoping that it will inspire the development of more actual game engines that do more than provide a collection of bindings.

I've wanted a Lua game engine that loaded levels, provided entities, had multiplayer out of the box, and everything else you'd expect from a game engine and not just some Lua C API bindings to OpenGL, OpenAL, and Box2D.

It turned out I had to build it myself.
The maximum amount of power emitted from a WiFi radio in the US as regulated by the FCC is 0.071W. You're not realistically going to notice much heating from WiFi. Have you ever tried to cook something on the antenna of your WiFi? Try putting a cup of water next to your WiFi router and measure the temperature difference. You'd need massively super-human levels of sensitivity to begin to notice any warming effects. Sure, if you crank the output up to a few dozen watts you'll definitely start feeling the effects of RF. Get it a few dozen watts higher and you'll be at risk of getting RF burns after some prolonged exposure. Get it several hundred watts higher and you're cooking a dinner in the metal box.

As for possibly almost seeing things like WiFi, that's also pretty preposterous. WiFi operates at 2.4 or 5.8GHz. Your eyes start to get sensitive EM waves at about 4000000000GHz (lower end of what is commonly called visible spectrum). Even if you were at the ultra extreme low end of sensitivity, you still wouldn't really be anywhere near the frequency range required.

So for your example of standing in a fire or having a spotlight on your face, you'd need for it to be a practically room temperature fire or a millionth of a candle spotlight. The scales you're comparing to are just silly to the point of being meaningless.
New construction in New York can have hundreds of units. I don’t know why you would automatically assume that 7,000 is a “frightening” number.
Voters are too stupid to form their own decisions, but oddly, that doesn't mean democracy is a sham.

Democracy exists because voters are too stupid to form their own decisions. It relies on the hope that stupid decisions are largely random, while informed decisions will all tend in the same direction. It takes only a small minority of people to know what they're doing, if the uninformed ones can be counted on to mostly cancel each other out.

That's obviously a fraught assumption, but mass media puts an increasingly large wrinkle in it. It takes only a small thumb on the scale of uninformed votes to overpower a minority of informed voters, and new techniques increasingly enable people with a lot of money to apply that thumb. If only 1% of voters are informed, and a misinformation campaign can sway 2% of otherwise evenly-divided voters, it becomes the dominant factor -- even if the informed voters are unswayed.
Go ahead and build, but make damn sure you are being rational about people's behavior when it comes to driving and transit.

My ex moved into a condominium complex that has exactly zero parking spots or loading docks for visitors, and no parking for half a mile in either direction. It's an absolute total fail. Neighbors rat on each other to get each other's cars towed because they get so upset. It's literally impossible to have a party there or even invite friends over because they simply cannot park and there is no transit available anywhere near there. There aren't any bike lanes either because it's a financially strapped city and the complex is near the border of a rich city that explicitly does things to make it harder to get between the two townships.

I'm just saying, both hands have to know what each other are doing and people have to make rational decisions at the municipal level.
The point is NOT that "famous" people have opinions. Of course they do, for the same reason that nobodies like us have opinions. The Wall Street Journal is absolutely welcome to tell you to vote for Trump if you happen to be reading its editorial page. Your union leadership is welcome to tell you they think Warren is great and endorse her; you voted for them and presumably you care about their opinions. Taylor Swift has been known to endorse the occasional candidate too. Shaping our opinions based on those of people we trust is the way things are supposed to work.

The problem with paid advertising is that this breaks down. Now it's not the "people" we trust that are telling us this stuff, it's the "places" we go to find those people. There's a difference between Zukerberg telling us who to vote for and Facebook taking money to plaster our feed with Bloomberg ads. So people who are likely to "trust" their Facebook feed (which is most people) are now at the mercy of whoever is willing to pay Facebook the most money.
If I find I am not getting something immediately, I study its pre-requisites.

Ultimately, I wanted to stop reinventing algorithms, which in turn forced me to review math. After that, additional layers of knowledge became much easier to stack.

Remember that C was easy for its creators. :)
