Indeed the typical wisdom in math is that the best way to understand a group (and the reason we usually care about one) is its actions.

There's some quote to the effect of: "Just as with men, a group is known by its actions." This was the only reference I could find off the top of my head https://gowers.wordpress.com/2011/11/06/group-actions-i/, but I've definitely heard the sentiment repeated in a couple different texts.

The sentiment expressed in this article might useful to hear if you're solely interested in learning how to use monad transformers or whatever in Haskell, eg, I know a fair amount of math, but very little category theory, and manage use monads just fine without any deep intuition as to why they're an important formalism. But if you want to develop your problem-solving skills, for example, I think "quiet contemplation" of axioms is pretty much always worse than working through several examples and absorbing some good exposition.

Here's a recent article that I found very though-provoking: http://cognitivemedium.com/invisible_visible/invisible_visib.... They quote some mathematicians discussing their visual intuition for one property of groups.
I can't understand the difference between the definitions of Identity and Invertibility - can someone explain?

I.e.:

Identity	For any element a in G there is an element e where e⋆a = a⋆e = a.

Invertibility	For each element a in G there is an element b where a⋆b = b⋆a = e, where e is the identity.

> Are users tracked any more on a Chromebook than a) a MacBook Air running Chrome b) a MacBook Air running Safari

Can you use a Chromebook without being logged in to a Google account? Can you block ads, trackers, and other creepy JavaScript on a Chromebook? Even the ones from Google?
> Did you try applying for jobs that specifically mention remote, like those found via https://www.google.com/search?q=remote+jobs ?

Yes.

> Was it ever to easy to find a remote job?

Sometimes, sometimes not. I've been working remotely since 2008 because IT jobs are lacking in my area. Unfortunately, and of late, employers respond with something like:

"Unfortunately we're not looking for remote at this time", or "You have to be in the US for this position".

There are some companies that accept remote, but as you said, they are the exception, not the rule.

> A total side-note: there's no such thing as "average of 17 years of experience" when you're talking about just one person.

Can you elaborate on this? Why is that wrong to say? English is also not my primary language.

I actually have something like ~17 years of programming experience.
I'm not so sure. Look at the module sizes the largest one at the bottom is still much smaller than modern batteries. If the battery had to be in one of those they'd have issues with longevity. Maybe allowing additional packs but trying to fit a main battery into it is going to require compromises somewhere.
That's cool man! I always wanted to get into Vue.js also. I really like the framework.

Go seems awesome as well. There are just so many frameworks and languages now, who knows what to pick any more haha!

It also has the interesting property that all the programs are quines except those that print themselves.

Illumos (Solaris) has been around for a while. It was probably written in the 32-bit era.
The domes of Drop City were neat, but the mathematics of the geometry they used, which Steve Baer called Zome (“zone” + “dome”) is also fascinating. https://en.wikipedia.org/wiki/Zome http://72.10.54.125/images/resources/-DomesZomes.pdf

In short, it’s what you get when you try to turn the icosahedron and dodecahedron into a practical construction toolkit. Everything fits together remarkably well, using struts which scale in length using the golden ratio τ = ½(1+√5). Indeed, every point you can construct using the system lies on a "golden integer" grid, with x, y, and z coordinates some integer combination of 1 and τ.

I recommend anyone interested in geometry, or anyone who knows some 8–18 year old kids, buy some Zometool toys, http://zometool.com, which are really fantastic tools for learning about geometric modeling for mathematics, physics, chemistry, architecture, computer graphics, .... [The company site doesn’t have the best pictures IMO, but check out a google image search https://www.google.com/search?tbm=isch&q=zometool]

By the way, for anyone interested in manufacturing, the Zometool spheres are pretty ridiculous (basically impossible, but somehow they did it) to injection mold. Check out this amusing essay http://bridgesmathart.org/2011/cdrom/proceedings/135/paper_1...

>You're actually supporting the GP's point,

Part of the GGP's point was that management has a role to play, and that they know things developers don't. That is the conclusion I was responding to.

You are right too, of course, we still had a process.
I'm not elitist at all. I am simply pointing the fact that someone who has an attention span of 2 minutes and refuses to search for help when facing an unfamiliar situation has a problem in the first place.

Let's not try to make everyone believe that our machines are the issue, where the issue is clearly cultural before everything else.
The integers >= 0 have 0 as the identity: 0 + n = n + 0 = n. But they don't have inverses, because e.g. there's no positive number n such that n + 1 = 0.

As a vegetarian teetotaler, I end up partially subsidizing most other people's meals.

We do split checks evenly though (one of us pays), and use Splitwise to register that. It's just better all around to have this kind of accountability. Over the last couple of years, I ended up being owed mid 4 figures on Splitwise (from all my friends combined) even though none of us makes an extra effort to avoid paying checks. This may be a weird outlier, but this goes to show that the small charges add up, and it doesn't always cancel out.
Just wanted to second this. When I climbed in Ontario, the cedars were pretty common knowledge and avoiding them at all costs was one of the tenets of being a good climber. Like any group, undoubtedly there's people who don't care; my experience was that most did.
You can't infer that, just as I can't infer there is for the majority. There's not enough data.

I suspect there is downside for far more than is generally believed.

How many jobs carry some googling of candidate? Nearly all of them.

You can now discriminate against just about anything you can dscover in search. Politics, religion, "too many" photos of parties, pro or anti any topic. None of these things are the business of an employer or landlord and would never come up pre-google unless you chose to share them in your application.

It's naive to assume none of these occur extensively. Gender discrimination has been illegal for years yet is still widespread.

I would consider that an inexpensive cost to learning about negative characteristics of my friends.

Or I would just not worry about it. We all have our issues; a friend worrying about $4 probably means there's something behind it. I can either accept that person along with all their issues or I can find new friends.
Given that one has a desire to purchase investment returns and purchase the feeling of doing socially responsible things, it is highly recommended to purchase these separately. Most products available for "socially responsible investing" are mutual funds who use social responsibility just as a marketing angle; they often charge 100 basis points or more higher than vanilla offerings from Vanguard or similar. (Performance prior to fees is similar; no definition of socially responsible investing or socially irresponsible investing creates alpha over the market.)

I can appreciate that one might capture utility from knowing that one does not support institutions that one thinks are odious, even in the _extremely attenuated_ nature that beneficially owning a few shares of their stock counts as support. That said, weigh the options here: 100 basis points drag on your return over your investing life costs hundreds of thousands of dollars. If your choices are a) sleep the sleep of the righteous while doing nothing of positive value for causes you care about or b) give causes you care about hundreds of thousands of dollars at the cost of occasionally owning ~5 shares of a company whose operations you dislike, which sounds like a better option to you?

Edit to add:

People might feel like I'm not being concrete enough here, so let me use an example which (playing the percentages) is specifically chosen to gore my ox rather than yours. Ave Maria Mutual Funds has a variety of actively-managed and index fund products which are targeted specifically at Catholics. Specific example: AVEMX. Their investment criteria is, basically, "US equities at any sizes in any industries at our discretion; we promise not to invest in anyone who supplies abortion, embryonic stem-cell research, or pornography."

People have entrusted this fund with $200 million. I will elide their investment results, as you should assume that any fund will probabalistically get market results going forward, and focus strictly on their expense ratio: 1.19% per year.

If you take out the Catholic angle, this firm is selling exposure to the US stock market. A competing way to buy this exposure is through the Vanguard Total Market fund (INT), or its ETF (VTI). Vanguard charges, for the mutual fund, 0.16% per year (103 BPS less) or 0.05% per year (114 BPS less) if you get their admiral shares (minimum investment: $10k).

You should reasonably expect approximately 8% average returns over the long-run in US equities. Maybe less. If you invest $10k in the Vanguard option and hold for 30 years, you will have $96k. (I used the more expensive of the two options for giggles.)

If you invest in Ave Maria and hold, and Ave Maria gets market returns, you will have $60k.

$36k could do a lot of things a Catholic might care about, which is why I am not invested in Ave Maria, am invested in various Vanguard funds, and have an exposure denominated in tens of dollars to e.g. IHG, a hotel chain which earns basis points of its revenue from selling pornographic movies.
> It's radioactive for that long because it /is/ waste.

I'm not sure what you're saying here? How does being waste make it radioactive?

If it still contains valuable energy it isn't waste. By virtue of the fact that nobody wants it I'm assuming that energy can't be extracted economically at this time?

I agree; but the value in these tools is very transient based on cat-and-mouse.

For precisely this reason they become useless when open-sourced.

And on the other hand it's not like they're great works of art. They're weekend hacks driving a rest API or phantomjs. Most of the "art" is threading or concurrency and getting it all to go over a 4K line "free proxy" list without falling over too badly.

Want 10k Twitter accounts? It's not magic. It's just some dumb scripts and a bit of patience.

You don't need massive server power (a $5 droplet will do fine) but you do have to have a bunch of time to waste.

Ooh, thanks! You've managed to combine my most and least favoured institutions here. I'm finding the Santa Fe Institute's research (and researchers) fascinating. GMU, OTOH, strikes me as automatically suspect due to its extreme pollution from Koch-funded Libertarian ideology, though I realise that doesn't infect all researchers or departments.

I am liking the look of this language. It looks very modern, and neither a retread nor outlandishly experimental or hacky.

What it would need to start feeling viable:

More documentation about implementation details, e.g. runtime environment, memory allocation model. "Ground-up" engineering info.

Some key libraries for a target application domain - web, gaming, etc. The "best option for X" approach.

Ability to deploy Stanza into other environments: Source to source, an easily implemented bytecode format, etc. The "parasitic" approach.
Not so long ago they were saying this about COBOL.

When there is a competitive advantage to adopt the latest best practices, they will. Maybe not this year, but the day will come when even the legacy python developers will jump.
And one costs about $10,000 more (approximately 25% more than the price of the Volt, a rather large difference to most people). And considering it's a BMW, you pay extra for a steering wheel, brakes, etc. (that's sarcasm, but really, BMW is one of the brands that's great at nickel and diming their customers, and don't forget about long term cost of a vehicle, much more expensive to fix a BMW than a Chevy. I know this because I have one of each, non-electrics)

So yes, it may be better because of the carbon fiber infused paneling, but you're paying for that. To ignore the price of automobiles when comparing them, is simply ridiculous (you're not the only who has done this devy, so this criticism is not pointed specifically at you.)

Actually the compression stroke can only lose you energy. It's the power stroke that you want to be as long as possible for maximum efficiency.

On top of this, there is an upper bound to the compression ratio for a given fuel-air mixture due to auto-ignition (basically if you compress a fuel-air mixture enough, it will ignite on its own).

So by having the compression stroke shorter than the power stroke, you can harvest more energy at a given compression ratio.
My understanding is that in Midtown there's been a stronger appetite for building tall on the avenues vs. mid block between the avenues.

> A sadder reflection is how Taiwan still isn't considered a country internationally

Perceptions do not change reality. Taiwan has free press and their own directly elected government.

Also, many people in China do know that Taiwan is its own country. No tax dollars are going to Beijing from Taiwan. Taiwan is completely sovereign.
Thanks for the links, I didn't previously know that Feynman was a synesthete.

Grapheme synesthesia is the most frequent type of synesthesia. I'm also a grapheme synesthete which is no doubt the only talent I'd have in common with Feynman. What makes this form of synesthesia a feature and not a bug is illustrated by research showing grapheme synesthetes probably have above average visual learning ability.

I can say that the sensory phenomena do tend to dim with age, but for me it was quite vivid as a kid, numbers, letters and words were strongly "colored" automatically. That did help memorizing things that schoolwork required, but in my case not tremendously helpful for solving math problems.

I looked at the PDF. Feynman's description is rather like my experience, though I'd emphasize that individual numbers and letters had unique, stable "colorization". IOW it's not that all numerals were blue, but that 0 was cyan, 1 was black, 2 yellow, etc.

Likewise A or a was red, B appeared green, b looked yellow-green, and so on. Combinations of letters in words would take on a meaning communicated as particular blocks of colors, that is, certain key words or phrases were readily identified.

Kind of weird to write it out like that but I believe it did make it easier to get through the rote parts of schooling. When I got bored sometimes I'd toss things around in my head, colors flying everywhere. The teacher could never guess what I was thinking...

Each synesthete has an individual sensory pattern, and syntax highlighting schemes are probably quite a bit different from synesthetic perception. Nonetheless what you show is very likely a good idea. I sure appreciate using syntax highlighting for code editing, suggesting there are good reasons to think it's worth applying elsewhere.
Doesn't this support the OECD opinion piece? Security guards can do a lot. These machines do almost nothing. Even in a total puff piece, they weren't able to come up with a single example where the robot actually did anything, except to run into a person by accident and have its photo taken in selfies.
For the usage you describe, i would actually recommand a Tablet ( iPad ) rather then Chromebook. I was actually waiting to upgrade to iPad Air 3, but instead we got a 9.7" iPad Pro.

From a hardware perpestive, once the iPad Air gets 4GB Ram, there is very little difference between it and the Chromebook.
I had a chromebook for about a year. I tried to make it my main laptop. I really did. But online only apps just don't work for me (I'm not always close enough to an internet connection). The native apps weren't usable enough, and often froze the whole desktop. Crouton, while cool, is flaky. I never did get audio working on it, and it also froze the system once or twice a day. And the lack of local storage became problematic. I could plug in a USB flash drive, but some stuff HAS to be on the main drive, and shuffling things around is a pain, especially on their file manager (which is SLOW, although not quite as horrible as Mac's file management).

I gave it to my dad, who just loves it! He uses it for his email, browsing, document editing, photos, and videos.

If that's all you do, then Chromebook is the system for you.

I'm sorry to say, but your code for example. While I love your click library it has many small issues. Which annoy the heck out of me.

Okay the Mazda 1.3L NA Miller cycle in the 2 is essentially the same cycle as the Prius. It probably won't have the best acceleration in the world, particularly at low RPMs.

When the Prius came out, I remember several people saying you couldn't call it a Miller cycle due to it being NA. (Actually a few people said it needed a positive-displacement supercharger, until it was pointed out that the original Miller cycle patent was paired with a turbocharger).
Build a virtual reality world on blockchain technologies from the ground up. Make it procedural, in spots, so the storage costs of pretty things aren't crazy high. Take changes enabled by the observer's causality and write them out as updates where there is consensus available. At the end of "time", you have a stored reality you can replay and enjoy, or even create sidechains of favorite events and share them with others.
And this exactly is the beauty of free software. The core team is free to drop support or do whatever they want. One thing they cannot force people to upgrade. They will upgrade when they want to upgrade.

Personally I tried upgrading a couple of times, but partial or no support of Python 3 from libraries I depended on, stopped me from doing it.
One of the most popular "distros", current release is named El Capitan, is still python2. Sure there are some "homebrew" incantations that can change that, but it's still a bother.

I'm a casual user of Python, and a heavy user of OS X command line, and it will be really nice if/when Apple finally changes this.

Yeah your right, there is loads of literature on it. Now I am internally confused what the ethical consequence of that is. What should happen in policy? Should we mess with the societal bio machine? Is it a good thing, or a bad thing. What are we trying to achieve?
Well there's a certain consistency to what you can do in a browser. E.g. Opening part of the app in a new tab or searching for things on the page. A soon as you're in flash or an Applet all bets are off. It might work, might not. Its jarring. (Of course this ignores single page apps that deliberately break things like right click, etc.)
