Yes. Getting a private sushi chef will make you happy. But after your 1,000th straight day of having your own personal sushi chef make you meals, it starts to become mundane and no longer provides much of a net positive effect on happiness.

What will significantly effect your happiness long term is negative things happening to you. Not being able to pay your bills, not knowing if you're going to lose your home next month, eating ramen because it's all you could afford - these sorts of things eat at you.

The $75k figure people throw around is the point where, supposedly, you're making enough money that you will avoid most of the stresses/negatives of not having enough money so there's nothing dragging you down from "baseline". Adding more money after that will allow you to make marginal increases in your happiness, but nothing significant relative to removing those negatives.
Hmm first time I had a semblance of grasping what the heck a monad was. Cool.

300 dimensions seems like way too many to have any kind of spatial intuition about. For me, it's easier to think of a n-tuple where n is 300. I'm not sure really what the cardinality of each dimension in this problem is, but I'll assume its a) the same for every dimension and b) something like a subset of the natural numbers (like, one int per 100k english words or something).

The sphere part is a little confusing at first, but it's really just a fancy (and yes, elegant) way of specifying a constraint on the n-tuple. Given some radius R, it defines the constraint sum(n_i^2) = R^2 for i=1..300.

It might be useful to normalize R, and it is convenient to select R=300 so that the average contribution of each n_i^2 term is 1. At this point, you just have to pick 3M n-tuples. I would probably use a random number generator to a) fill in the n-tuple, b) adjust a constant factor to fit with real world R, and c) repeat 3M times.
Wow. The first should class as attempted murder.
Well it's not borderless, its just you don't need a visa for a fair number of days (1 week to 6 months) and it will not accompany the right to work or study.

Currently very few African countries offer visa on arrival or electronic visas for other African countries' citizens.

While it's not the same as the EU's version of a borderless union, it's a great step forward.
All the tutorials involve using base R packages. While OK for a tutorial, this is not reflective for real-world data analysis both in performance and usability, a lesson I have learned the hard way. (After using it for three semesters in college, I almost quit R completely in frustration)

I recommend going straight to the Hadleyverse packages for the common use cases, and read the vignettes for the common use cases: readr for reading files, dplyr for manipulating data, ggplot2 for plotting (the most important package!), and tidyr for reshaping data into a ggplot2-friendly long form.

Wickham himself has a very beginner-friendly, free book for learn R using his packages: http://r4ds.had.co.nz/index.html (far better than any tutorial I could write)
There's a introductory book that I would add to the "generalist" list, that is 'Linear Algebra Done Wrong' by Sergei Treil.
It can be found freely here: https://www.math.brown.edu/~treil/papers/LADW/LADW.html

I've used it to prepare my linear algebra exam in an italian university (which usually emphasize theory over practice, even in engineering courses), and I've loved it.
There are few exercises but they're to the point. Complex inner product, self-adjoint operators etc. are treated. I find the notation used in there particularly easy to understand, and proofs are elegant but very easy to follow.

Mine too, but that doesn't make it a good comment. In fact its first paragraph is almost a parody of the know-it-all internet comment.

There are a zillion ways to make the same kind of argument thoughtfully. Talking about one's own concrete experiences helps. So does not acting like you know everything about somebody else's situation.

Bloat is a problem, and so (in my view) is the kitchen-sink software culture of hauling in libraries and frameworks without thought for overall complexity. But we need to be able to talk about this at a higher level than other-people-are-idiots-compared-to-me. A much higher level.

"I would like my desktop to feel like a desktop, and not like a tablet."

So, you don't like Windows 10, either, I guess?

I find it to be even more insistently tablet-like than Gnome (which I agree has some elements I previously only associated with Android, and I was slow to adapt, but I've come to be very comfortable with it). My new laptop has a touchscreen, which is a thing I didn't want...but it was the only way to get a 4k screen, so I have it, and I've even come to like it. My habits are evolving slowly, and it'll probably be a year or two before I even remember to touch the screen more than a few times a day, but I think the evolution is a positive one. That said, in the "cons" of having a tablet-like interface, Windows 10 has a "feature" that makes your start menu different every time you open it, which I find very difficult to use (I have to start typing to find anything always). That's just awful. But, I think I would hate it on a tablet, too.

For the other stuff, I kinda like the minimize behavior (but never use minimize...I use virtual desktops to determine what's in and out of view), I think the extensions API has been stabilized for a year or two now. Gnome 3 shipped in some distros when it was not ready (even though they were calling it stable, it wasn't), but it's firmed up a lot. Now, they're mostly doing incremental improvements. Each time I upgrade now (and I've been using Gnome 3 since it first shipped with Fedora) the surprises are small and pleasant (of the form "Oh, that looks nice!").

In short, I agree with some of your criticisms...but, only when applied to Gnome 3 of a year or two or three ago.

TOTALLYNOTCHEATING@YAHOO.COM
I was recently bored and watched, after years of avoiding it, The Traitor (2008), with Don Cheadle as a terrorist ... or not so-terrorist. The movie was pretty bad (there's the real spoiler!).

In that movie, which I just check the date for, seems like one of the first pop references to the idea of sharing email drafts in a free email account without sending anything.

https://www.washingtonpost.com/news/worldviews/wp/2012/11/12...

Now, can someone prove me one better and find where this idea got traction? I honestly laughed watching that movie, wondering if Petraeus watched it years earlier, and thought to himself, I wonder if this will work in real life ...

UPDATE: I could, gee, also try RTFWPA! It refers 2005 reports of AQ using the same tactic, you know, where probably he got it from.

Or he got it from the movie, which would make me in a die a fit of laughter!

The one thing that gives me pause is that it's relatively easy to steal a bicycle, but it's difficult to steal a car. Here in Portland, bicycle theft is an enormous problem, and I'm not willing to spend hundreds of dollars on a bike that could be stolen with impunity.
I'm very very pro devops. But I am cautious about auto scale.

It adds a lot of complexity. If your app has predprtable load it may simplify stuff a lot to not auto scale. Think a b2b app with manual account creation. You know your user levels. 0 reason to turn on auto scale.
Happily, most people are able-bodied, and for those for whom a regular bike will never be an option, there remain cars, buses, light rail, electric bikes, and so on and so on.

As for showering, I think that will probably start to matter less as time goes on. In the last few years, in the Pacific NW, I've noticed it's become somewhat acceptable to show up to meetings a bit sweaty, if you've just gotten off your bike. At least, among the business meetings I attend, of course.
Why no Halmos, "Finite-dimensional vector spaces"? It's pretty theoretical but very approachable also.
I think the regional keyspaces would be have to be caches -- denormalize it, basically. Pop/re-fresh people into the geo-based caches as they moved around. Truth sits behind it, centralized (perhaps partitioned in some way that makes sense globally but is sub-optimal from a regional cache perspective). Might not be worth it -- hard to know from here. :)
In a different thread some time ago [1], I wrote:

"The bot hype right now isn't about average UIs being replaced with text prompts of "What would you like to do today?", it's about large walled-garden ecosystems (Google, FB, Amazon, Apple, MS, Kik, etc.) funneling web searches and services through their own systems."

I believe the hype isn't driven by the desire of people interested in Natural Language Processing, but rather by providers of chat apps who want to track your 'click-throughs' and engagement; and by service providers like Uber and Papa John's who want to expand their services' reach into the hands of users who may be running FB Messenger or Whatsapp or Kik, but perhaps not running the Uber or Papa John's app.

It's uniform if you reject points with length > 1 before normalizing (your link mentions this), but not uniform as written. It's a simple adjustment, but you do have to cull.

I completely agree that image is as important as tech, if not more so. Likewise, that it would be 15000 well spent (noting that this figure is 10x the budget in our original post)-- if we were close enough to product/market fit that we could afford it.

It may be strange to you but running a mailserver was pretty normal back in the day and even now I see nothing wrong with it. In fact, I see a lot wrong in having just a few email service providers that get to dictate terms. There is arguably something wrong with how hard it is to properly set up and secure a mail server, but the concept of running your own mailserver is no different than running your own HTTP(S) server.

> As a comp sci person, you can't improve what you don't measure. Tests are how you measure. So I get it. But if I decided to measure the page load time of my server to ultimately improve server performance, no one is really hurt by that.

The problem is when you write something to measure that and then ask someone else to solve the problem. Systems like this almost always lead to optimizing for the measurement, not the end goal.

I mean, sure, at first I'm going to optimize code and work to increase efficiency to get the latency down because I actually care about my work. If that doesn't get me to the goal you've set and you keep hounding me and eventually tell me that if I want to have a job next year I'm going to get the page load time down...

I'm probably going to start stripping less-used features, maybe having the server occasionally serve a nearly blank "Click here to Refresh" page to game the average, see if I can't specifically serve less content to your measurement application... All of this results in a worse experience, but a better metric.
> I have fairly mixed feelings. In theory, why would a state need to create their own education curriculum?

The issue of who should create a curriculum is orthogonal to Common Core, because Common Core does not provide a curriculum. It is essentially just a list of goals and a schedule for when students should meet those goals.

For instance the standards for the "Measurement and Data" part of mathematics say that Kindergarten students should be able to describe measurable attributes of objects, such as length or weight, directly compare two objects with a common measurable attribute and state which has more of or less of that attribute, and group objects by a measurable attribute.

First graders should be able to order three objects by length and compare two objects the length of two objects indirectly by using a third object, use a simple ruler to measure objects that are an integral multiple of the ruler size, tell and write time in hours and half hours using analog and digital clocks, and do some simple organization and interpretation of data with up to three categories.

How a state gets to those goals is up to it. It can develop its own curriculum if it wishes, or adopt one developed by a national publisher, so something in between. The arguments for and against these possibilities remain largely unchanged with Common Core from what they were before Common Core.
Ask HN: UNDERUSED SPACE BRAND and APP
Put simply we have built a database of beautiful underused spaces in major cities such as New York, San Francisco, and DC. (Over a hundred convenient spaces) We are first launching a mindfulness & wellness brand that leverages these beautiful underused spaces for mindfulness-linked yoga, meditation, and fitness offerings.

Particularly, the marketing of meditation as a commercial entity is largely stuck in the 1960's and we hope our brand with accessible and approachable offerings can shift this dynamic. The research backing meditation is enormous, but their still lacks many places where it can be done in ideal group settings with great instructors. Additionally, our platform of spaces significantly reduces overhead so great instructors with solid followings will truly be able to get paid significantly. It is our hope that this can create a virtuous cycle of attracting more quality meditation and mindfulness instructors into our society. Any thoughts on the specifics of building out a mvp of a map based app would be very much appreciated. Feel free to check out our very basic pre-launch site at 2b-infinite.com or to shoot me a line with any thoughts at Connor@2b-infinite.com. All love and thanks in advance for helpful feedback.

Of course, I've configured my server to properly sign email, publish SPF records, and so on. My server may be small, but god damn it, it's top notch.
>Since the western media almost never reports anything on Africa, does anybody know how the AU is progressing?

Slow progress, but progressing none the less. Seems to be poorly funded so their latest idea is to put an AU tax on all imports.

The whole thing seems to lack direction beyond a vague desire to prove that Africa can be united like the "big boys" i.e. EU.

The passport thing will take off I think. It'll take a while & cause serious security issues but I think they'll do it.

>Are they pushing for a EU like model?

They're copying some things, but don't seem to be doing the whole Brussels centralised power thing.
Using Docker tags to mess with people’s mind
Point taken. I'll try to do better next time but it does get old after a while of seeing the same set of mistakes and articles parroted over and over again. Trivial problems blown out of proportions because people don't know the proper science, theory, and history and have opted to re-invent things badly. Uber is especially known for this since they re-invented/re-wrote basic geospatial algorithms in Go and hailed it as innovation.

The dismissal comes from years of reading such articles and then chipping away at the veneer to see what's really underneath and being disappointed every time and then working on such things and experiencing first hand how the bloat comes about.
I own that book and have worked through a few chapters. It is one of the first linear algebra books in a "modern" style, being published in 1958. The reason it's not on the list is I just didn't see what it had to offer that isn't covered in later books. Happy to be convinced otherwise though.

I do have Halmos' linear algebra problem book on the list because it's quite good.
I remember the horror I felt when first reading about threads in Novell and OS2 back around 1990 or so.

Threads provide a lot of research opportunities. Should they really be exposed at the application programming level? Java was a nice try, but I think any language that is going to tightly integrate threads should emulate processes and interprocess communication, isolating casual variable references between threads.

Cue: somebody more knowledgable than me discuss Erlang here...

The Netherlands does this very well. Car traffic is nicely separated from bicycle traffic, which is nicely separated from pedestrians. There's even an entire nationwide network of bicycle paths.

I suggest using Google street view to look around. Usually, you can see a bike path off on the side of the road that's nicely separated from the cars. I don't think that Google has gotten around to taking street view pictures in all the bike-only paths in more rural areas, although I hear they've done that in some places.

The Netherlands has been committed to improving bicycle use and safety since the 1950s, so they've built up a lot of infrastructure with that in mind. In fact, I hear that in any accident in the Netherlands involving a car and bicycle, the car is always at fault unless they can prove that the bicycle was being reckless. It makes cars a lot more careful, and encourages riding a bike instead of driving.

From what I hear, the effect is from all this that automobile traffic in is pretty congested and slow. The Dutch government seems to be making a general policy of discouraging car driving and encouraging alternate forms of transportation, as a means to unclog the roads and reduce pollution. The Netherlands is very dense, so pollution would be very bad if all those people were driving everywhere.

I'm not Dutch, but sometimes I wish I were, because I would very much like to bike to work on a regular basis. My city in California has some bike lanes, but they aren't very wide and are right next to the cars. They've been starting to build bike paths that are completely separate from roads, but we don't yet have a city-wide bike path network yet. I suspect we'll eventually get one, but it will be decades away. I'll go biking with my children on quiet residential streets or the bike paths, but there's no way I'd take them on the bike lanes on the bigger roads.

Greater frequency.

And let's not forget that driving tests are not standardised in the US amongst states. So depending on where you live, your test could either have been something that really checks if you know how your car works, how to safely do maneuvers, how to react to emergencies and how to drive with other cars on the road, or it might have just checked that you can drive around a block. Fix your driving licence tests at a national level, then maybe you'll see how the DMV is useful.
