I have a problem trying to generate the document with: xelatex src/front.tex

It is generated but without icons. If I see the file front.log I think it's trying to write the icons using Fira Sans:

Missing character: There is no  in font Fira Sans/OT:script=latn;language=DFLT;mapping=tex-text;!

(The line shows 9 times and there are 9 icons too)

The vibrating belt compass was actually pretty useful, from what I read. The people who used it reportedly got very good at forming mental maps of where they were and improved their navigational skills.

The downside was that some of them experienced nausea and disorientation when they discontinued use of the device.

Legally, duress is defined as "any unlawful threat or coercion used... to induce another to act [or not act] in a manner [they] otherwise would not [or would]".

Key word there is unlawful. Unfortunately, the Supreme Court has upheld that searching and seizing your device at the border without suspicion or warrant is lawful if done for the public interest. [0] (Insane, no?)

The guy in charge of making the decision weighed the fact that it's closed source, and it still won.

> But to me, the development process is more important than worrying whether a cloud-based service publishes its source code... This is especially not a worry as GitHub is not a walled garden; its extensive SDK allows for downloading any and all data that goes into the platform.

In summary, his reasons were: github has become a social network of open source devs; gitlab has no killer features github doesn't; and Guido prefers github

My personal feeing on the matter is that proprietary software can harness a lot of talent and usually delivers a better end user experience. For example, the creator of Twitter Bootstrap works for github full time. How else will you get talented people thinking about how to make a product better all day?
Many early cars had windscreen wipers which were operated from the engine vacuum.

The disadvantage was that when you floored the pedal to pass a truck, the wipers stopped working, just when you needed them.

Conversely, when you lifted off the throttle, they flapped insanely fast.

As a hobbyist programmer, I have to say this is a fantastic idea. I often find it difficult to come up with dummy problems to solve in order to get some programming in--having a real issue to work out is far more inspiring.

While I find such a view fairly gross, this is not very charitable. What is particularly insane about it? Troublesome, even wrong, doesn't make something insane. I've seen such a view stated many times. I hope we can do better than moralize, it just drives people with views like this further to the fringe.
As always with this author, I followed a link to a math explanation video expecting to point out how it is only a superficial treatment that breaks down under rigorous analysis, only to be dissapointed in my inability to find any such flaws. Seriously, this guy is awesome. If you need to learn math, see if he has a video about it.

I do have 1 gripe with this video though, and that is his handwaving around "natural".

More specifically, as far as this particular case goes, there is nothing natural about the choice of e^x, or the significance of pi.

As he identifies, we are interested in some function that maps adders into multipliers with the property f(x+y)=f(x)f(x).

To uniquely identify such a function, we need to add an additional constraint. He chose to add f(pi) = -1. He justifies this by arguing that pi is the length you would travel along the unit circle to arrive at -1. This is true (and the underlying reason why pi and e end up being natural), however using this argument seems to break the abstraction for me.

Under this construction, in the equation f(i * pi)=-1, "i * pi" is an object in the set of multipliers, and "-1" is an object in the set of adders. Specifically, "i * pi" is a function which takes a plane (or perhaps a point) and rotates it, while "-1" is a function which takes a plane (or point) and slides it.

He then invokes an unstated mapping, g, to convert the multiplier [0] "i * pi" into the real number "pi". He than insists that g(x) gives the distance a point would travel along the unit circle when the multiplier x is applied to it.

At this point, because arriving at the point "-1" [1] from the point "1" through rotation requires traveling pi distance, it makes sense that f(i * pi) = f(g^-1(pi)) = -1

I am still not convinced that (within this construction alone), this is a more natural choice that saying that f(i) = 1, but would agree that it is one of the two natural choices. To get to f(x) = e^x being the natural choice requires showing that it comes up in all sorts of unrelated parts of math, so it is probably more natural.

[0] It might be better to speak of "rotational multipliers" here, as I am not sure how to natural define g(x) for multipliers that stretch the plane, instead of or in addition to simply rotating it.

[1] This "1" is again distinct from the adder "1" and multiplier "1", but plays a central role in defining them, so I do not object to its usage.

"Our body is made for this world, it's pretty good at sensing it."

I don't know about that latter part. There are so many animals with really amazing senses that make humans seem primitive in comparison.

Wouldn't you love to have the nose of a bloodhound or the ears of a bat? Or be able to see the infrared or ultraviolet spectrum?

That's not to mention all the many senses that are conceivable but not present in any known species, or the potential for synesthesia, like tasting colors or hearing smells, etc. Humankind has a very, very long way to go to fully sensing the world around us.

Many of these untapped senses are super useful, too. An enhanced sense of smell or sight could very well save your life -- some dogs, for instance, have been able to smell disease conditions (not to mention their renowned tracking ability which has saved many lives and solved many crimes).

I think it's legitimate to say, in a discussion like this one where we're not dealing with punishment, that we should hold to a weaker standard (preponderance of evidence?) than should a criminal court.

That said, as far as I'm aware the only evidence we've seen is that he's been accused of the crime. I don't what portion of accusations are false (or even a proxy like conviction rate in comparable situations).
That rather depends how you value your time w.r.t the opportunity cost of doing other things. Valuing my marginal time with a purely internal cost metric of $500ph, that $20 equates to a tipping point of 2.5 minutes a month on the complete hosting setup & management. Since it will invariably take more than that even amortized over a year it's a no-brainer: I'm okay with paying for blog hosting, assuming it's a service offering the same capabilities and quality level I'd build for myself.

NB: I receive no additional value clawed back from DIY since I do not desire any additional experience with building, configuring, securing, managing, monitoring and maintaining web servers and/or content management systems.

Even the expensive stuff like "I Can't Believe It's Not Butter" is nearly repulsive compared to real butter IMO.

Not to mention that the US is going to continue to expand in terms of population. We've added 60 million people in 20 years, nearly equal to the population of France. We'll add another 20+ million in the next decade.

Simultaneously we'll become slightly less rural and more urban in terms of population concentration.

Even if the autonomous electric vehicle has a huge role to play in improving traffic in the US - which it clearly does - high speed rail (whether hyperloop-like, above ground, below ground, whatever) will still make sense alongside that. There is going to be plenty of demand to go around, such that having multiple approaches will be useful. Sometimes the autonomous car will make sense, sometimes rail will make sense.
Cholesterol isn't bad, it's in fact very important for the production of testosterone among other things. The problem comes from the inability to use it because the body isn't healthy. Polyunsaturated fats will produce bad byproducts when it breaks down and over time makes the body sick.

We crucially lack magnesium and potassium in our diet. There are tons of studies showing the benefits of magnesium against heart disease. And it's not just the heart, cholesterol can obstruct the liver and a sick liver will cause a whole lot of problems.
Their actual financial investment in the company was likely nominal if anything at all. Spotify likely offered an ownership stake as an incentive to get the labels to take a chance on an unknown company and an unproven model.

Whether Spotify goes public or not the labels have already made out very handsomely was my point. That's the $5 billion that Spotify often states that it has paid out to rights holders. So yes it very much has borne fruit, $5 billion worth. If the company goes public its basically gravy for them.

The record labels were decimated back in 2006/2007 when Spotify started. Things looked pretty bleak for the industry as a whole. So yes the labels needed to do something as their revenues has pretty much dried up comparatively to a decade earlier.
Also, FDA labeling allows "0g trans fat" for food with 0.5 g per serving, and listed serving sizes are often laughable, so I wonder.

Dunno how much weight to give it; I try to avoid those oils anyway.

I'm curious why he doesn't just claim that he forgot the key. There's no way to prove conclusively that he's lying, and a judge cannot jail someone for disobeying a court order that they have no way of obeying. If he's told them he knows it and just won't give it to them, then this bridge is probably burned, but it's probably his only shot. Absent a ruling from the Supreme Court on this issue, they can and will hold him until he complies, dies, or has already served the maximum possible sentence for the crimes he is suspected of committing.

> no two cars seeming to have the same configuration

Have you noticed the rear brakes lights on cars? Absolutely every model of car has a different shape: triangle, concentric circles, polka dot pattern, you name it.

I doubt that anyone is the least bit influenced in their car choice by how cool the brake lights look.

I'd like to think that the car companies avoid making a standardized brake light to put a thorn in the side of after-market parts manufacturers. At least that evil explanation makes economic sense.

In reality, I think that car designers do what they like doing -- making new designs. Even in cases where it makes zero difference to the user. Even in cases where a standardized design would be better for everyone[1].

[1] Because of cost, availability (every garage would stock a standard brake light), detection of the standard rear light pattern by collision avoidance systems.

This is a parser generator that I'm working on:

https://github.com/tree-sitter/tree-sitter

It produces concrete syntax trees that can be queried by line or character index. The library is specifically focused on incremental parsing, for use in a text editor, but it also works fine for normal 'batch' parsing workloads. It has a simple C API that you should be able to use from any language. Currently, there are bindings to JavaScript and Haskell. Here are some example grammars:

* C - https://github.com/tree-sitter/tree-sitter-c

* JavaScript - https://github.com/tree-sitter/tree-sitter-javascript

I think there is both a good and bad aspect of this quote, you've done a great job highlighting the bad.

The good, is in essence that you don't always need to be fully comfortable and in fact will not always be comfortable. I find in mathematics if you try to always strive for total comfort you will never progress, as a lot of the comfort comes from advancing past a topic and upon revisiting it you realize you understand the fundamentals better than you thought.

I have no interest in reading the book... because of exactly this: I had to read sophomore year of highschool, it was boring, left me with no desire to read it. And I could never understand why my teacher loved it so much.
I've seen this a while ago, and while it's pretty instructive, it's actually also pretty confusing. The magic happens in a seemingly-innocuous throwaway sentence at around 4:20 (after being introduced to the 2D plane):

> ... This can now include rotating along with some stretching and shrinking ...

It's entirely non-obvious WHY we should be okay with rotating all of a sudden. The real answer is not super complicated, but it deals with a couple of amazing relationships between exponential functions and trigonometric identities[1]. So really, we don't have to accept "rotating" as some weird new action we can do when moving into the complex plane, we just have to accept that trigonometry is weirdly related to analysis due to some very cool properties.

Just to point out, for drive by commits (eg typo fixes, etc), GitHub is super simple:

1. Go to the file in GitHub you want to change
2. Click the "Edit" icon
3. Click the "Create Pull Request" button

There's no need to create a fork and branch manually any more, GitHub does it automatically behind the scenes. It's a useful optimisation. :)
