By "extends" here we formally mean "normed division algebra". Basically, we want any 2D slice of our space to be equivalent to the complex numbers. This is analogous to how the reals embed into the complex plane or how slices of vector spaces are still vector spaces. We don't want things to depend on a particular basis (i.e. implementation).

Anyway, it's pretty easy to make up some multiplication on 3D vectors, like multiplying their components. However, in general, it won't play nicely with such arbitrary 2D slices. As it turns out, this slicing property is equivalent to having multiplication play nicely with vector norms:

|ab| = |a| |b|.

that is, multiplication of vectors multiplies their lengths. Getting a multiplication with this property is the hard part, per se, and is only possible in dimensions 1, 2, 4, and 8.

I think BFT can be added as an option to your database and it wouldn’t need refactoring any other part of the database. Just have crypto signatures and the log would need to use BFT consensus with a quorum before committing. May be worth it at least for marketing purposes, but also for multiple mistrusting parties jointly running the database. You’ve done so much already, may as well benefit from this addition!

Exercise should be enjoyable or people will not do it. The second you start talking about benefit for unit of time spent it becomes a tedious chore. I love rock climbing, I hate running, no statistic about running being more beneficial is going to make me run.

I have introduced tons of friends to the gym and my first piece of advice is always just show up and have fun, don’t worry about ideal routines or maximizing output. Just figure out how to make exercise part of your life.
Someone else has already said it, but location.

I live in Santa Monica and would love a space like yours. But going between the westside & downtown -- particularly during rush hour -- just isn't reasonable for a regular thing. It'll take easily 1hr+.

I had hope the Expo line would help, and while it does a bit, its current speed still makes it a long journey, timewise.

I didn't take a deep dive of the code but in order to train it's going to need to be fed audio files with the actual video/mouth shapes/etc. Essentially it needs it to tell the reward to give back (if it was right). Once it "learns" it wouldn't need the audio file.
No, I was referring to the group of non-zero quaternions. There's a double-cover from the group U of unit quaternions to SO(3) though. If you care about SE(3), there's an obvious surjection U x R^3 -> SE(3) where the domain is "a translation following a rotation". This is a homomorphism of Lie groups.

I just don't get what you were going for with "use Lie groups instead". Everything here appears to already be a Lie group. How am I supposed to use that?

That looks beautiful. Why don't we make nice clean Uis that use space well anymore? Why is everything now light grey on dark grey, and 80% blank space?
You’re looking at inflows and outflows, which in the early stages of a ponzi scheme can also be similar. The way that social security in the US is a ponzi scheme is that the benefits paid out are not interest or earnings on the amounts paid in by the people receiving the benefits. They are paid for by new people paying in to the system. That is almost the definition of a Ponzi scheme.

> There is serious disagreement about this (the two camps being cardio vs strength training, basically).

Huh, strange to hear this. I do strength training (basically a lot of compound lifts like squats and deadlifts and so on) and I consider them to be a cardio. If I do a speedy 12 rep set, I am properly spent and breathing heavy and see my heart rate at 160 and above
Grip strength is also an excellent marker of longevity/imminent death - but this is probably not a result of exercise, and certainly not grip-strength exercise. Science is not assuming that what seems like a very reasonable guess is true, and questioning such assumptions must be "pedantic." Instead, we do the experiments and know one way or another.

PS - one of the things that happens when most people exercise is more UV exposure as they walk, run or cycle: and previous studies have shown UV exposure to be more important for longevity than exercise per se.
Finally someone who has actually studied the blade.
> Something like 50% of runners get injured in a given year.

That's because most people use bad technique and would probably benefit from strength training as well. Sitting all day and then expecting your body to run for 30-60 minutes and then sitting again will lead to high risk of injury. I see a lot of people run like they're walking with longer strides, or hunched over, or any number of bad habits. The feet should land under your center of mass, not in front of it, and the turnover should be pretty fast. Short and fast steps instead of long and slow. Don't run too fast, use your core for stability, and keep an upright posture, slightly leaned forward at the ankles.

Look up proper running form, do some drills, and add body weight strength training a couple of times each week if you're thinking of starting running.
I wonder if a cryptographer could take a look at Meow Hash. I'm curious how it would fail first when subjected to modern cryptanalytic methods.
I'm surprised they don't get all the admissions data and do some data mining with machine learning to figure out admissions trends. That would be the easiest way to prove whether or not there is any real bias.

To me the most suspicious thing is that the demographics of different races remain just about the same year after year after year. That reeks of manipulation, just like how Madoff's returns were almost always perfectly similar year after year.
I wonder how much land area has been rendered unusable from pollution by oil, coal and gas compared to nuclear. I suspect even by this measure nuclear would prove far preferable.

The difference is many tens of thousands of smaller sites affected by fossil fuel pollution and accidents as compared to a couple of large incidents.
Wow. That is some powerful sarcasm!

How is it controversial? There are at least 2 credible papers proving it works and the empirical experience of mine and of other people I know demonstrates its efficiency.
Also, in Hamilton's time they didn't have the view of mathematics as axiom systems that could be played with. Math was a way of finding Truth, so the idea of making up multiplication rules at your convenience probably seemed like an extremely non-obvious move.

The discovery of complex numbers and quaternions probably played a big part in getting people to question what math is, leading to Hilbert's program to study Foundations etc. Hamilton's story is a nice, rare single instance we can point to, symbolizing this discovery.
This article, and the Barnes and Simon article it is critiquing, are not exactly casual reading, friend. Are you the author of this article? Could you break it down a bit for an interested outsider?

In particular, if the EEA is not so important, what is the value of including fraternal twins at all, compared to, say, other close siblings? And doesn't it raise questions if a mathematical model gives the same results regardless of whether or not the assumptions used in its development are followed?

Also, what do you think of Barnes and Simon's reply:

https://www.gwern.net/docs/genetics/heritable/2015-burt.pdf

I understand if you don't have time to answer in detail, all of the relevant paper is probably pushing 100 pages of dense inside baseball at this point. I merely wish for the folks with, ahem, deep convictions about heritability up-thread to understand that this paper isn't as unassailable as its press releases are making it out to be.
> caused the nation to be so terribly divided that it will take years to recover from the mess they created

The nation is divided, but NYT isn’t to blame. There are two sets of people, with very strongly held yet divergent ideas of what this country stands for, and what direction it should go in. The New York Times has nothing to do with that.
The last time I made my case for a promotion, the director said "Sorry, no promotions right now, there's nothing I can do."

A couple months later, a coworker gets a job offer elsewhere and threatens to leave, and he's immediately promoted. He happens to be the least experienced engineer, and now he's leading the team.

This sends everybody scrambling for job offers, since that's what gets rewarded. Half the engineers have left already, and with any luck, I'll be next out the door.
don't overlook genetics, there are family lines that just live longer regardless of many what people consider bad habits. exercise rightly cannot be dismissed but all the exercise in the world won't fix what is in your DNA.

It is easy to subscribe to actual people with similar interests who "boost" (repost) the kind of content you like.

I've seen this so much now that I feel like I must be missing a piece of the puzzle.

You work for a company for X amount of time, and you gain domain knowledge of the company, and general industry experience. Some other company looks at your CV, and without knowing you, and probably without caring about your specific company domain knowledge, decides you are worth say 20% more than you are earning.
You then go to your current company, and say 'my general skills are worth 20% more on the market, you know how well I work, and you know I have extra domain knowledge specific to this role, I would like more money' - and the company refuses.

They then spend time and money finding someone with similar skills to what you have, but without your domain knowledge, and probably at a similar amount you asked for since that's the market rate.

How is it not in the companies best interests to just keep you on and give you a raise? How do they justify all that wasted time and money every time? Do they just not measure it?

Oh man. My PhD work is focused on helping people communicate clearly about the measurements they are making and how to interpret them and where the pitfalls are in a research setting. Every time I read about something like this I wonder if I can use what I am working on to help people automatically detect when the assumptions of their measurement model could be violated. For example, if you can explicitly model the fact that the measurement is not the actual value and that they can become decoupled (and can thus brainstorm and model potential reasons), then you can start to help people realize that the map (measurements) are not the territory (reality), in ways that aren't just cute phrases without guidance for practical implementation.
Preference for children of donors and legacies are such blatantly racist admission policies, it's shocking that they're even legal. The fact that this lawsuit is targeting affirmative action rather than those policies is incredibly telling.
Not a manager, but I meet with my engineering manager once a week.

We set the ground rules early on that we'd avoid the two extremes of the topic spectrum: project status updates and venting about issues that neither of us can take action on to address.

I'm given free reign to choose a topic and drive the meeting. Unless there's some pressing matter, I fallback to reviewing the work I did the past week and how I feel it helps (or doesn't) my career goals.

I try to give good examples of gaps I'd like to address so he can look for such opportunities in future projects, conferences, or in-house training.

My goal is that my manager will have a good understanding of the type of specific tasks I like to do and/or that will better help my future.

> If your arguments lose to fake news, then you should get better arguements.

It’s not arguments vs fake news, it’s real news vs fake news. And that’s the difference between real news and fake news—if you don’t like your fake news, you can get new fake news, again and again and again, until you end up with a lie so beautiful it makes your heart sing. But you can’t get new real news, this is the only reality there is, no matter how ugly it is. But it’s still harsh reality, instead of a beautiful lie.

We've already seen that internet conservatives will prey on the elderly and other susceptible types on Facebook with fake news. And it works. Even if it gets retracted or disproved later (and not everyone sees the disproving), the false image has been imprinted. I expect this to be used in this way shamelessly.
Not all big cats roar (as opposed to just growling) -- and it important to realize that saber tooth cats weren't closely related to any living cats but were on an evolutionary branch of their own. So it is an interesting question.
Once a week for 30 mins, and I never, ever reschedule them.

I treat these meetings as untouchable because I want my direct reports to know that I value them. I don't want to reschedule and make them feel like I don't care, so I will never reschedule them.

We don't discuss their weekly work or tasks, we discuss their careers, their career path, how they can get to the next level, any problems they are encountering, etc. I dedicate this time to them and their career and their time at the company.

There's a great description of how to run a 1-on-1 in High Output Management by Andy Grove.

I like to have them every 2 weeks with a new hire, and every month thereafter. Sometimes, if something comes up midweek that feels like it needs to be addressed, I'll schedule one before that.

Structure--

Location: take a walk or go to a non-work but private space

Ask questions about their general feelings:
- How are you doing?
- How are things in the office? With co-workers?
- Are you enjoying your work? What could make it better?

Ask them for feedback:
- Is there anything that's been on your mind? Any issues either with me or other staff?
- Is there something that we could be doing better in their eyes? What would they change?

Do they have a career goal they are progressing towards?
- What position would you like to be in 1-2 years?
- What can I do to help you get there?
- How do you feel your recent projects have helped in that regard?

Only after I exhaust them and their feelings will I bring up feedback I have for them -- again, with exceptions, if the 1-on-1 was called to handle a specific issue, that will be addressed pretty fast.

- What do you do in terms of inks? Presumably water based?
I second the Manager Tools podcast, it has been great for getting started with engineering management. Here's what's distilled down from a lot of their intro casts:

1. Have a 1x1 once a week with each direct for 30 min

2. If you can have your 1x1 walking (go for coffee, head outside) try and do that; conversation flows easier when it's not in a confined space like a meeting room.

3. Loosely allocate the meeting in 1/2: 15 min for them to talk about whatever they want. 15 min for you to talk about what you need to talk about (usually top->down information), and at least leave a few min at the end for career development or tactics.

4. Throw out rule #3 if they want to talk more than 15 min. Always cut your portion down to accommodate them. The point of the meeting is to build trust. Building trust means listening to your directs and getting to know them and what makes them tick. You'll always learn more by listening than instructing.

And that's basically it, that will get you a long way for now!

I do weekly half-hour 1:1’s with all my direct reports. Each one is pre-scheduled for the same time every week. I almost never cancel, although I do reschedule sometimes.

The first half is for whatever they want to talk about (work status, planning, career guidance, personal stuff, anything they want). The second half is for my list: usually tactical work stuff, but I step back and ask about their overall feelings and professional goals about once per month.

It’s a useful tool for coordinating work, and it has the nice side effect of redicing interruptions because most things can wait a few days until our 1:1. But the primary reason I do them so often is to build stronger relationships. I know my people very well, and they know me. Spending so much time together builds a lot of trust, which is extremely valuable.
The actual linked article says it aims for very complex things and simple (one-function) things but not in-between. I haven't looked into what that means in practice, but that's what's written.
