Oh interesting. What phone are you using? It should enter a mobile-friendly kind of view, but I haven't implemented that on the server side renderer yet.
You may want to consider mobile-friendliness purely client side, using CSS to set up different layouts depending on the resolution - what's typically called Responsive Web Design. Sounds cumbersome, but with just the right couple of design tweaks you may get 90% usability on mobile.
Actually, I think the issue here now that I think of it is that we do media query detection in on the React side to figure out which components to render. Really, we should just render a single component and have CSS to cover both cases.
Other sites do this, so it should be possible, though it would require me to change the react component that renders the sidebar (I'm using Atlaskit, but that doesn't have support for mobile responsive rendering, sadly).
Yeah, for some reason I saw 60,000(!) requests on lambda all at the same time so I guess it had a bit of trouble scaling up. A scraper or Googlebot perhaps? Should be all fine now.
It probably could be, as long as I figure out how to get code splitting to work with it being a static site. Shouldn't be too hard. I imagine its just a case of pre-rendering all the routes and then uploading the whole thing to an S3 bucket.
Super cool, I didn't know that existed. Clearly someone else has had the problem I experienced too. I'll have to add that with a list of other useful resources on the site.
Thanks for the feedback! I was a little worried that the explanations would fall back too much on formal properties, so I guess I've got a bit more work to do on the visualization side of things.
I think you are doing a great job here. I looked through your sections on determinants and inverses, and it is so much better than the way I was taught: "this is the formula for inverting a 2x2 matrix. This bit is called the determinant." For me, learning always works best when I know what we are working towards and seeing how it works, and putting the formal definition first is rarely effective in that. Start with a specific example, concrete where possible, and generalize from that.
Indeed. I think one of the thing I wanted to focus on as well in this series was explaining exactly where a lot of the formulas came from. It was a great learning experience, since a lot of what I was taught was basically as you said "here is the formula for the determinant and oh look, NxN determinants can be worked out in such and such a way if you just apply this algorithm". It was super useful to decompose why that algorithm works from a visual perspective. Same thing with surface integrals.
There's no perfect order for everyone. The trick is to spiral around revisiting levels and styles (and don't worry if you don't grok a part yet) until they all start to gel and your brain forms aweb of connections.
So many people think the second book they read on a topic is soooo much clearer than the first. But it doesn't much matter which book they dead first vs second :-)
The 'second book effect' is an interesting point, but that phenomenon, by itself, would suggest that there are improvements to be made in how we teach things from the beginning.
I actually got my inspiration to do this from the 3b1b videos. And I agree, they are very fine educational materials.
The gap which I'm trying to fill here is that 3b1b goes over the higher level intuitions but tends to skip over some of the details at times (which is fair enough, they're a pain to demonstrate through video and animation). The idea I had here was to have worked examples as well.
I support open borders and this is one of the points that I've grappled with for quite some time. I'm not convinced that the decision to move from developing country to a developed one is made purely on economic grounds. Permanently relocating your life is not an easy task. You pretty much have to give up all your social capital, all your community ties (which means that you could face ostracisation back in your birthplace), learn a new language, learn new cultural norms, spend significant funds on travel and relocation costs costs and whatever savings you have left will lose a decent chunk of their value due to exchange rate conversion. You also have no networks to exercise in finding employment in your new home and finding accommodation without any kind of reference is going to be difficult.
In that sense, the risk to oneself is so great that only a privileged few in developing countries who wanted to relocate would actually have the resources to overcome them. So for many people, relocating might legally be a choice, but it would be practically impossible.
Realistically, migration is only an option for you if you (1) have a job offer from a company based in the place you intend to migrate, (2) have sufficient funds + skills to cover yourself until you can find a job, (3) have family who can support you and lend you their networks until you can find employment, (4) have sufficient funds to start your own business. Incidentally, those criteria also form categories of US visas (H1-B/TN-1/E-3/L-1, O-1, Family Reunion, EB-5), though, they impose more stringent requirements than economics would.
(Re: your first paragraph) - and yet, we see millions of folks undertaking dangerous journeys over the Middle East or Mediterranean or Central America or Indian Ocean to reach Europe/USA/Australia.... What gives? That life must be very shitty in many parts of the world??
Some of them might not, but quite a lot of them have at least one of those; some have all three. It's not uncommon for illegal immigrants from Mexico, particularly, to be people who would be eligible for family-based immigration but for the expense and decade plus backlog. It's also not unheard of for those that have connections in the immigrant community to have an (likely off-the-books because of documentation requirements) job lined up.
A ballot paper that doesn't clearly indicate preference order or identifies the voter is counted as "informal" and removed from the pool [0].
I don't believe it is an offence to vote informally but even if it was the anonyminity of the ballot woult make it impossible to enforce.
In the last Federal Election the overall informal vote share was about 5.92%. In some electorates it was above 10% [1].
The AEC doesn't distinguish between votes that were intentionally invalid and votes that were unintentionally invalid. I used to work as an electoral officer and in my experience the latter usually far outweighed the former. I saw very few if any ballots that were totally blank, about 10-15 where the person tried to make a statement of some sort and the rest were people who did not understand the instructions and number every box.
As far as I can tell, elections in Australia are seen as something you don't really ignore despite your individual disdain for politics.
