(Replying to myself since we hit the nesting depth.)

1. Here's a deeper intuition: any circle is just the unit circle, scaled up or down. Any number is just 1.0, scaled (and rotated, if complex) by the exponential function that was run for some rate and for some amount of time. e^rt is a rocket ship of constant change, we just decide how long to stay on for, and we can get to any number.

In other words, for any number a: a = 1.0 * e^ln(a)

This formulation is useful if we know we're going to be taking exponents on our number a, i.e. we really want a^b. (If we know we'll be rotating our number, maybe we write it in polar coordinates, etc.)

So, the intuition is: "I know I'm going to be taking my number to various powers, so let's get the base settings for e^rt dialed in. pi/2 is the setting for how long we'd ride e^i for in order to get to 90 degrees. I should expect pi/2 somewhere in the answer as I take it to various powers."

2) I haven't taken complex analysis, so my understanding isn't nuanced enough here either. Technically, i^i can be multi-valued, for this graphical analogy let's settle on the principal root (https://www.math.hmc.edu/funfacts/ffiles/20013.3.shtml).

> (e^(2 i pi))^(1/2) is not e^(i pi), it's e^0.

(e^(2 i pi))^(1/2) is asking for the square root of 1, which is both 1 [e^0] and -1 [e^(i pi)]. Again there may be a subtlety here, but I'm not sure how the above statement is incorrect (barring a technicality like "we always mean the positive root"). For the purposes of an intuition it makes sense, I think.
I love this one, #19

"If you find yourself blaming someone, you’re probably wrong. Nobody wakes up and tries to do a bad job. 95% of the time you can resolve your feelings by just talking to people."

That could just be a general statement that would do wonders for people to think about.
All I want is modern Thinkpad hardware (i7, 16GB or more RAM, at least 1080 screen, but hopefully 16:10 high res) with an X201 design. Even a T420 design would do.

I'd pay a few hundred bucks for an aftermarket keyboard/trackpad system to replace the crap Lenovo ships.

I heard a while back that to be the biggest winner, you need to be in the nano-second range for your latency (for example, you would need to rent server space at the stock exchange and not be running any firewall/etc to have minimum latency) ... I don't think that he is talking about the large players in his articles because he is still in the millisecond range which is very slow for this purpose. In 2011, microseconds were apparently for big players (http://www.youtube.com/watch?v=kjIdzBtTBnI)

Agree with basically everything here. The biggest surprise about engineering management is that it's less about making technical decisions and more about nurturing other people to make technical decisions. It's almost entirely people management skills that don't even specifically apply to engineering.

The other thing is the role is very rarely leadership and more service. Leaders usually blossom from within your teams naturally.

Frankly I find the disclaimer disturbing:

> I do not claim to be the owner of any content related to this course. If you are the rightful owner of this content and wish to have it removed, please contact me (<email omitted>)

It is clear that this github repository is to serve no purpose but a rehost, of a copyrighted content(it is open in a sense that it is freely available, but the copyright still belongs to the PG and so on.). While a mirroring is an acceptable contribution to a freely available content, sometimes even encouraged, I've always figured that an accepted approach is to inquire-then-serve, rather than the opposite.

Another problem is that the disclaimer that is supposedly to protect against claims of infringement, proudly calls for the original owners to action, if in case of infringement. Does this mean that this mirror will stay unless the original author spends effort in hunting down these mirrors?

Judging from the email address, I think the guy's heart was at a right place(just because it is an university address) and just wanted to help sharing the good knowledge. Hopefully the share may be moved to more appropriate way.

There's not much there about the management triangle - cost, schedule and scope. The hard part in management is navigating between these vertices day by day. It's great when you can take "cost" out of the equation (and often partially schedule for some time at least) because of VC funding, but the truth is that you have it much easier than most other managers.

HBR is full of similarly writted golden thoughts written by really experienced managers and leaders, however it is hard to relate to them in normal business scenario, where the customer is almost screaming at you because of deadline approaching, the sales team sold something that doesn't exist, the cashflow is close to negative (no VC).
That's the sense I get too.

A few questions:
1) Why would one want to be directed by someone sitting half a world away other than journalistic situations?
2) How would this be different from Skype, hangouts, facetime, etc.?
3) What is the incentive for someone to open up their smartphone's camera feed for broadcasting specially if it incurs data costs for the broadcaster?
4) What is the guarantee that the broadcasts are not of someone's genitals, ala, chatroulette?
5) Unless video is HD the feeling of "being there" is diminished considerably and having HD video takes high bandwidth and costs for the broadcaster without an incentive to do so. How would you address this conflict?

I agree with the vast majority, however I will focus on what I disagree with because what's interesting.

- Your team looks to you for leadership. Have the courage to say what everyone knows to be true but isn’t saying.

I don't look for management for leadership, I look at management to resolve conflicts that due to a hierarchy they are the only one given the authority to do so.

Leadership is found everywhere, and management doesn't have any more or less of this quality.

- Most intellectual arguments have strong emotional undercurrents. You’ll be dramatically more efficient once you learn to figure out what those are.

I'm not sure what you mean here. If you mean by strong emotional undercurrents, biases.. sure. That's extremely important to determining how rational a decision is.

I don't think it's particularly emotional though.

- Once everyone is heard, summarize all points of view so clearly that people say “Thanks, I wish I’d thought of putting it that way.” List any points of agreement with each view, and state what you’ve learned from everyone. Then make your decision.

I don't think this is because, "I wish I'd thought of putting it that way", and more to validate that you understand the issues and arguments. If everyone can agree that you've at least stated the situation properly, we have a foundation on which to make a decision.

-When disagreement gets personal or people don’t accept well-reasoned decisions, it turns into conflict.

Is that a lesson? When things are conflicts, they turn into conflicts.

-If the conflict persists after you’ve gone to reasonable lengths to hear everyone out and fix problems, it’s time for a difficult conversation.

What are you implying? Firing someone? What is this difficult conversation you're talking about?

.... There's a difficult conversation section after this... I'm getting the impression you mean, dealing with a conflict and telling them to suck it up. Okay.

- Occasionally someone will push too far. When they do, you have to show a rough edge or you’ll lose authority with your team.

I don't need shown a rough edge. You have authority because the company gives it, that's all that's required. Perhaps these are just the types of people I don't deal with, and thus don't have this experience.

...

By majority a lot of solid advice and thoughts. In there are some odd phrasings and issues. Perhaps many people take value in this stuff, it's quite possible as a person I don't feel the need for much of it because I'm not the type that requires it.
Im glad someone actually points this out. This is the real news.
> How do you write code without fixing bugs and shipping features?

What I meant here is that you have to fix an occasional bug and ship an occasional feature, but only in order to remain an effective tiebreaker. Fixing things is no longer your primary job. During crunch time new managers often feel that the best way to help the team is to dig in and fix things themselves, but in reality they can help much more effectively by doing other things.

So fix an occasional bug, but remember, you're only doing it to stay in tune with the codebase, not to ship things faster.

> What do you mean by tiebreaker?

I'm talking about making decisions when half the team thinks "we should do X" and the other half thinks "we should do Y". If the team can't reach consensus someone has to decide, and as a manager, that's you.

For what it's worth, I complete agree with the parent poster.

I carry daily, but generally don't have a firearm on my person when I'm at home. That said, my front door is down a flight of stairs, and there is a rifle just out of sight at the top fo the stairs.

As for the odds of needing it... well, they're obviously quite low. I live in a low-crime area and a large portion of my income goes to ensuring that is the case. Even so, my town (Charlottesville, VA) is currently in the national news because a college girl was abducted off the street about a block from my office. There have also been a handful of home invasion robberies in nearby towns over the past couple of months.

It seems extremely reasonable to at least have the option of using an effective weapon to defend one's self.

Never stop digging. Just realize you can only dig into one thing at a time, and be selective about what that is.
Leakage, customs, national security issues, etc. If the government of a country says they need to inspect a specific cargo container or you can't come into port, it's easier to make that possible at sea rather than having to steam elsewhere and completely unload, especially since you'd likely have to refuel en route and it would be a very long trip due to the rareness of ports capable of handling such ships.

Studying a hypothetical high-speed train given that no existing high-speed trains are used primarily for freight? (And that air freight is widely used.) I doubt it. High-value goods can already be delivered quickly and low-value goods can be delivered quite inexpensively. Container ships have, in fact, revolutionized goods transport.
Perhaps some kind of pirated Minecraft client is the vector? Java is needed, mods to that area are probably ignored, and the malware is connecting to a Reddit Minecraft forum which is something that is almost certainly not blocked by the victim if they're a player/fan.
I am extremely concerned with:

> [Don't] Personally fix bugs and ship features.

So, obvious but mostly irrelevant concerns: Team size. If there is only one person you manage, this is likely a mistake. You don't clarify when this rule kicks in, but I assume we don't actually disagree on that point.

I am also concerned that you seem to place no emphasis on engineering excellence in those who manage engineers. I've yet to see a single example of this working out well, but it could just be that you didn't mention this and the stuff you did mention paints a picture not representative of your beliefs.

My primary concern isn't with making up 40 hours of management for one person, nor non-engineering managers.

My concern is that I've seen excellent engineers promoted past the threshold where they're writing features like everyone else. And their responsibility to manage started trumping the professional necessity to push back on things "the management team" would give them. In one example that sticks out, he started bending rules, making them up, and breaking them anyway. I've seen well meaning people turn a blind eye to criminal fraud and people stealing from the company.

You can't be an effective leader if people don't see you as part of the tribe. CTOs are often considered part of the management team, and not part of the technical team. I cannot imagine how this makes them better at their jobs -- but if they are in-group for the management team, I understand how it makes them seem like they are better at their jobs.

There are some strong indications that the boom in manufacturing in China is not permanent. With the decline in the importance of labor, the rise of robots, and the importance of protecting IP in manufacturing, Byrnjolfsson and McAfee suggest that much of manufacturing will be coming home over the next few decades.

The most important metric in this type of transport is efficiency (i.e., mass delivered / energy consumed), not speed. I can't imagine anything more efficient than cargo ships in this case.
Marine shipping in cargo containers is frighteningly efficient. In 2002, the cost was $0.001 per mile per ton[0] Good luck beating that price with a drone. It'll cost more in electricity to fly a drone-package across town than to move a cargo container across the ocean.

Great book and it also very much speaks to how, for example, processes and regulations/contracts may need to change in order for a new technology to be used effectively. Most people don't appreciate the degree to which containers underpin the globalization of manufacturing (for better or worse).
Apologies, won't happen again.
It doesn't necessarily make sense when you have a team working on different things, front-end devs working on the templates and back-end devs working on services, etc.

Furthermore most likely you will be sharing many partial templates or widgets between different views and sections in your app. So those have to go in some sort of common views folder, losing much of your grouping.

I wouldn't say either way is right or wrong, it just depends on your workflow, size of the app and size of the team working on it.
great advice here, I would have liked to see some code examples for #4, b/c I am currently struggling with a ng codebase where the controller are doing way too much in my opinion. using ui-router helps some, but, I would love to see more ways to keep the controllers slim.

What is your point exactly?

Some nonsense about all Arabs being XYZ (i.e. something as silly as equating Moroccans with Saudi Arabians with Arab Americans, same Arabs right?) and then using that to explain unsuccessful foreign policy in places like Iran, which is not at all an Arab state? (Only 2% of Iran are Arabs, in fact there are MORE arabs in the US than there are in Iran. Give me a break)

Let me know if you have more great insights. I always enjoy a good laugh.

The jobless rate is an indicator of difference between demand and supply for employees. With people out of work, of course salaries will shrink.

The mandate of the fed should be changed to correct for the data problems evident here.

The "easiest" way to increase (inverse) metrics is always to move people from the measured bucket (unemployed) to the not-measured one (non-participating).

If we shift inflation from assets < 1 year life to those of longer duration, we can manipulate that metric pretty well too.

Until composite metrics are better disseminated and understood, these things will remain underlying problems.
I wonder what kind of superpower-like abilities we're just one nucleotide away from.

I think we're a little further away than that. Just think of a huge computer program. Modify one line of code in the right place and you introduce a showstopping bug. On the other hand, adding a random line of code anywhere in the program is unlikely to produce a complex new feature.
