A newsletter about mental models and rational thinking - <AUTHOR> https://models.substack.com/ <comment><USER2> This is really good. It states a lot of things that it has taken me time and experience to learn, which I would have benefited from knowing early in my career. Authority is not always right, people in power have ulterior motives other than doing the right thing, when investigating a problem remove all assumptions and determine the root cause (this is both the hardest to do and also the best advice I've come across for any IT technical worker IMO). So many times I've seen people claim to have solved a problem by throwing a solution at it that appears to have worked, without determining the root cause, only for the problem re-manifest itself weeks or months later in a different manner.

<comment><USER3> My challenge with lists like these: When I first read these they feel like shallow platitudes, but after I learn these lessons through my own experiences they feel like succinct explanations of a deeper truth.

I never seem to really get a lot out of reading about them.

</comment></comment></comment></comment><comment><USER6> Great idea, looks really good. On the rational thinking topic: is there a name for the fallacy where you say something along the lines of "someone in group X would probably say Y and that's wrong because..."? X could be something like vegans, democrats or climate change deniers.

It's probably just a special case of a straw man argument but I see this often online and in the news to lure in replies and create outrage. It's hard to diffuse as nobody in the discussion will actually hold the set of views being presented. I usually want to reply "wait, who is actually making this statement that you're attacking?".

<comment> exo-pla-net When both a viewpoint and an opponent are fabricated, you have a Hollow Man argument.

</comment></comment></comment><comment><USER7> This looks intriguing. Welcome to the newsletter space! I run Thinking About Things [0], a newsletter with a similar premise - that of critical thinking and seeing things in a new light.

The demand for content about critical thinking is rising exponentially. I'm happy to collaborate and show you the ropes - you can find our contact info on the site.

<comment><USER8> One thing I've noticed about a lot of newsletter's landing pages is that they let you see past articles without signing up. I have no idea based on your intro if your content aligns with what I'm interested in, nor do I want to fill my email inbox with more content to just skim. Have you considered making your past newsletters available for prospective subscribers?

</comment></comment><comment><USER9> Perhaps its worth defining what you mean by "mental model"?

"Mental model" is one of those amorphous words that seems to mean very different things to different people.

Based on your content, it seems to mostly deal with critical thinking rather than what I consider as mental models. Though once again, it's an amorphous word thats unique to the person.

<comment><USER10> Absolutely, none of these are mental models by any definition that I can accept. These are advice or aphorisms, based on I suppose experience.

</comment></comment><comment><USER11> Congratulations on the launch of the newsletter OP.

Another news letter on rational thinking I would recommend is ClearThinking[1]. They also have several tools, tests for rationality/biases, specifically useful if we want to test ourself or someone else for a job for which these would be a problem.

</comment><comment><USER12> Any suggestions for how to actually apply (or remember to apply) this stuff? I've read tons of lists of mental models (and have even written my own), but I just never remember to use them for any decisions, and when I do remember I can't really find one appropriate to the situation at hand.

<comment><USER13> Maybe one way is to go back through some _past_ situations and review what mental models would have been interesting and/or useful to apply. That might help train yourself to apply them in the future.

</comment></comment><comment><USER14> Anyone else completely exhausted by the amount of discussion of mental models? It seems like the virtue signalling cliché of 2020.</comment>


Net neutrality is dead, but it probably doesn't matter - <AUTHOR> http://www.cringely.com/2014/01/21/net-neutrality-dead-probably-doesnt-matter/

<comment><USER2> I don't think he understands what nn means.without nn your isp can simply not connect you to say. A competitor of Netflix. Thus there can only ever be one Netflix. Thats a huge problem in a market where I only have one choice in an isp.

</comment><comment><USER3> Is it me or does this hardly make eny sense?

Bufferbloat has no effect on the available bandwidth in a completly switched network. (It might confuse protocols resulting in bad utilization, but has little to do with net neutrality.)

If ISPs limit the bandwidth available to each content provider, then bufferbloat does not enter into the picture. (Okay, depending on how the limiting is done, it might cause extra bufferbloat.)

</comment><comment><USER4> Fixing bufferbloat doesn't solve the fact that ISPs have lots of local monopolies and duopolies. If there's a sudden drop in bandwidth demand, there's nothing to keep an ISP from decreasing supply to create demand for a fast lane.

</comment><comment><USER5> Complaining about bufferbloat is a red herring. It doesn't matter if it's fixed if Netflix is trying to push 40 Gbps of traffic to a set of customers across some ISP's 10 Gbps interconnect.

A 5km Asteroid May Briefly Occult the Brightest Star in the Night Sky - <AUTHOR> https://arstechnica.com/science/2019/02/a-small-asteroid-may-briefly-blot-out-sirius-monday-night/ <comment><USER2> There is a flying telescope built on a 747SP, a joint enterprise of NASA and the German space agency, called SOFIA. It is able to fly to see events like this that can only be observed from a limited range of locations.

[https://www.abc.net.au/news/2019-02-01/sofia-flying- telescop...](https://www.abc.net.au/news/2019-02-01/sofia-flying-telescope- occultation-chasing-shadow-titan/10635802)

<comment><USER3> I think SOFIA is used mainly for Infrared astronomy. By flying above most of the atmosphere it can observe in the infrared, where Earth based telescopes are severely limited.

<comment><USER4> The purpose of SOFIA is to fly above as much of the water vapour in the atmosphere as possible to do astronomy in the far infrared and terrahertz regimes: frequencies that are absorbed by water. Near infrared astronomy can easily be done from the ground. As the grandparent mentioned, it is also used as a mobile telescope to do observations of stellar occultations. The purpose of this is to get a measure, for example, of Pluto's atmosphere as it passes in front of a star. I doubt it would be used for an occultation by an asteroid as you wouldn't gain anything by the measurement.

<comment><USER5> I suppose you could get information about the asteroid's shape?

<comment><USER6> Indeed they do. You can see some of the analysis here [1], by calculating the time period of the occultation and the transit location of the star across the body of the asteroid. I don't know how they account for rotation or how they so precisely know where the asteroid will be relative to the star.

<comment><USER9> Indeed from "The Nine Billion Names of God", but this classic of SF was by Arthur C. Clarke, not Isaac Asimov.

However, Isaac Asimov did write "Nightfall", another classic, which describes what happens when, as the result of an eclipse, the stars come out, rather than go out...

Also, it's a nitpick, but the frequently repeated phrase "HTML language" belongs in the same box as "ATM machine" or "RAS syndrome".</comment>


EMI, Apple To Sell DRM-Free Music for $1.29/song - <AUTHOR> http://www.techcrunch.com/2007/04/02/emi-apple-are-announcing-sale-of-non-drm-music/ <comment><USER2> The "test case" of DRM-free stuff that I'm most familiar with is Baen Books, who are selling DRM-free e-book versions of (almost) all their titles and -- according to themselves and their authors who are also have books published by other publishers -- "[earn] more income as a publisher and [pay their] authors more in the way of royalty payments from [their e-book line] than any other outlet for electronic books." Based on this, it seems likely to me that the EMI/iTunes experiment is going to deliver on its promise of making more money for EMI.

<http://preview.baens-universe.com/articles/auged> <http://preview.baens- universe.com/articles/salvos6>

Of course, it's a different medium, and Baen has also managed to create a community of users who like the company, not just its products. I don't see EMI replicating that, DRM-free music or no, which limits the applicability of the example. (The Baen people love telling the story of their users saying, "you should charge more for this." They created a premium version where you pay more to read an advance copy of the book before the official release date, and they're making money from that, too.)

</comment><comment><USER3> A good source on the economic harm of intellectual property law is the Against Monopoly blog <http://www.againstmonopoly.org.> Today's lead article mentions the EMI/Apple deal. Economist David K. Levine writes, "It will be interesting to see how many people buy the DRM version and remove it themselves."

</comment><comment><USER4> Many people in business literature mocked and called "bluff" on Steve Jobs' <http://www.apple.com/hotnews/thoughtsonmusic/.>

I think a lot of people who believe in the iTunes-iPod lock-in strategy don't understand that the vast majority of music on iPods is not from iTunes. Any iTunes-iPod lock-in that Apple has is through the seamless experience of syncing one's music onto his or her iPod through iTunes.

The move towards non-DRM music will help Apple avoid anti-trust issues in Scandinavia and make buying digital music a better experience for users. User affinity is the #1 lock-in strategy and no one knows this better than Apple.</comment>


The Magnus Effect and the World Cup Match Ball - <AUTHOR> http://www.comsol.com/blogs/magnus-effect-world-cup-match-ball/

<comment><USER2> I'd wager that no sport makes more use of the Magnus effect than table tennis. The ball is extremely light, and top players routinely spin it at 6000 to as much as 9000 rpm. And not just on occasional shots, either -- almost every ball is spinning heavily in some direction. I'd have to check to be sure, but I think the Magnus acceleration can be greater than that due to gravity. It certainly can be of the same order.

<comment><USER3> It can definitely be greater, because a table tennis ball with backspin follows an upward trajectory.

</comment></comment><comment><USER4> For details on how Roberto Carlos sets up a free kick, watch this video: [http://www.uefa.com/trainingground/skills/video/videoid=7611...](http://www.uefa.com/trainingground/skills/video/videoid=761187.html)

<comment><USER5> Thanks so much for posting that link. Carlos is so Zen when it comes to soccer: "The ball is for playing".

[http://www.sixtysymbols.com/videos/football.htm](http://www.sixtysymbols.com/videos/football.htm)

Sixty Symbols (from the University of Nottingham) does a nice job making videos about physics that are approachable for non-physicists.

</comment><comment><USER7> Lovely stuff. Back in my undergrad degree, the professor who taught basic fluid mechanics loved to use the Magnus effect as an example. I think his explanation would have been much improved by some FEA like we see here.

COMSOL's a cool package, incidentally. It makes FEA much easier for people who don't have much experience of it, but do know a fair bit about the physical phenomena they're trying to model. I had a few gripes with the system back when I used it for modelling thermal degradation in motors, but overall it was very impressive.

Dropbox: Files Without Borders - tomh- http://www.forbes.com/forbes/2010/0628/technology-file-sharing-dropbox-google-files-without-borders.html

<comment><AUTHOR> _Rodeo producer North American Midway Entertainment saved $25,000 in the first six weeks using Dropbox by eliminating overnight FedEx shipments with paperwork._

Wow. Talk about having a great story to tell. I'm sure there's a lot of individual users of Dropbox (myself included), but the business cost-savings angle could be a huge one for them to pursue.

<comment><USER2> Since Dropbox only does one-way access for people without an account, I assume they saved 25k by _distributing_ paperwork, not receiving.

This implies they've been wasting almost $5,000 _per week_ because they didn't find a content host / run an FTP / _frickin E-MAIL the stuff_.

What. The. (technological) Fail. You'd think they'd look into something like that a _little_ earlier, as with a bit of setup an FTP host can be essentially as easy.

edit: hell, just use a Google Docs form, that handles distribution _and_ filling it out and combining the results.

<comment><USER3> I think that's the point of Dropbox. Setting up FTP _isn't_ as easy. Dropbox is so friendly people use it in lieu of more complete, cheaper solutions.

<comment><USER2> Setting it up - absolutely. Using it once it's in place - pretty close.

I don't expect _them_ to set it up _themselves_. Just to hunt someone down and pay them a couple thousand to solve their ridiculously expensive problem.

</comment></comment></comment></comment><comment><USER4> Absolutely true. Dropbox is one hell of a cloud backup solution. With Dropbox iPhone app, I have all my important files with me in my pocket.

Does anybody have numbers on their current free/paid users?

<comment><USER5> From the article:

 _He won't disclose details, but probably 2% of Dropbox's members are paying customers, putting revenues at $14 million this year._

<comment><USER6> 2% is waaaay too high

</comment></comment></comment><comment><USER7> Google docs does handle most files for uploading and downloading. I don't use it much, but it's cheaper than dropbox, but less capable as well.

</comment><comment><USER8> Dropbox is just incredibly well done. I tried using services like xdrive, strongspace, idisk and a few others over the years and they all felt so cumbersome that they never stuck. Dropbox by comparison seems to sync incredibly fast, has a sensible way for dealing with conflicts, and just seems to hit a sweet spot of simplicity and functionality.

</comment><comment><USER9> dropbox is great but their upload speeds kills the service. I get around 40-60kb/s while on other sites i get 400-500kb/s

</comment><comment><USER10> Good to see Dropbox getting the coverage - it really is a killer application for end-users.

</comment><comment><USER11> They need to create some more paid plans. More variety would be wonderful!

</comment><comment><USER12> I still remember that HN post announcing his project, before getting accepted to YC.

<http://news.ycombinator.com/item?id=8863>

</comment><comment><USER13> Dropbox is definitely great, and it really do deserve its extremly widespread usage.

It has actually made it so simple to do a backup that it gets done. Most impressive.

</comment><comment><USER14> You have to use gnome to use Dropbox, hopefully they fix that. Then all the systems folk will probably use this for quick n' dirty research projects.

<comment><USER15> No you don't. I've been using Dropbox in KDE for months now.

Can I talk to that William fellow?  He was so helpful. - <AUTHOR> http://blogs.msdn.com/oldnewthing/archive/2009/11/23/9927055.aspx

<comment><USER2> This story is mostly true, although it's not quite how I remember it. In 1989 I was a product support services intern working at Microsoft's Lincoln Plaza campus. I worked for the 'System Languages' team, or SysLang as we called ourselves. We supported Micorosft C 5.x, QuickC, and their Pascal product and associated tools like the M editor and CodeView. One day (I don't remember if it was November or not) Bill came through on a tour of PSS. I mentioned to another intern, Nadine, that it would be cool if Bill took a call from a customer. When he came by our area with a group of other management types she bounded up to him with a huge smile on her face and asked if he'd like to see how things worked for himself, and take a call from a customer. The people he was with tried to dissuade him of this idea, saying something about schedules and the like, but Bill liked the idea and wanted to do it. At the time, I was a real clean freak, and my cube was very clean and devoid of clutter, so I suggested he sit down at my desk. I explained to him how the Aspect phone system worked and how to look up things in our STARS knowledge base using an OS/2 terminal program connected to a DEC minicomputer. He got settled in, and eventually took a call, greeting the customer like:

"Hello, Product Support Services, this is William, how may I help you?"

Just about everyone who wasn't currently on a call with a customer was gathered around my cube listening. I seem to remember the customer having a problem with the linker. Bill queried the knowledge base, which was normally painfully slow, but this time it was snappy and responsive. The first result looked like it might have addressed the customer's problem, and Bill went with it. I of course only heard one side of the conversation, but it sounded like the customer wasn't satisfied with the answer. Bill was firm yet polite, reassuring the customer that we had seen this problem before and that his solution was correct, and the customer eventually agreed to try the solution mentioned in the STARS article. An hour or so later, my friend Tad got that customer again, and he mentioned that William had helped him with his problem earlier but his solution didn't work. Tad let the customer know that he had in fact talked to Bill Gates, and helped him with his problem. I don't remember how/if it got solved though.

That was quite a big day for me. For years I had saved the yellow pad that had Bill's notes from the call.

<comment><USER3> Only on HN...

<comment><USER2> I also posted my version of the story to the blog's comments. Man, hard to believe that was 20 years ago. Hopefully some other SysLang veterans read HN and will post something.

</comment></comment></comment><comment><USER4> The best thing you can ever do for your company is to put every employee in front of customers. One of the things that attracted me to FreshBooks was that they rotate everyone through customer support continuously. As a (former) developer who was tired of consistently building the wrong thing because sales and marketing jealously guarded the customer, this was very refreshing.

This isn't a novel idea. Many companies with customer service orientations have done this. If you're selling Software-as-a- _Service_ , that ought to include you!

<comment><USER5> Not necessarily a good idea. I could probably handle it now without a problem, but when I was 25 or 30 I would have quit first, and you should have your head examined if you would have put me in that position back then. Given how many high functioning autists tend toward techie type jobs, it may even block your hiring good tech talent (it may even be an ADA violation).

</comment></comment><comment><USER6> What amazes me about this story is that back in '89 MS had a knowledge base that worked so well that a person not trained for customer service was able to provide the help needed just by looking in the knowledge base. Many companies still don't have a system that good yet.

<comment><USER7> What was Microsoft's product line in 1989? MS/DOS, Word, Excel and Windows 2.0?

<comment><USER8> It also included compilers and, specifically to the problem the user called in about, a linker. Compilers and linkers are no simple matter to support, particularly in those days.

BKS Iyengar, who helped bring yoga to the West, has died - <AUTHOR> http://www.vox.com/2014/8/20/6047603/bks-iyengar-who-helped-bring-yoga-to-the-west-has-died <comment><USER3> What I find interesting about yoga practices in America is that there is so much emphasis/focus on just the 1st level (Physical).

Physical - Annamaya kosha

Energy - Pranamaya kosha

Mental - Manamaya kosha

Wisdom - Vijnanamaya kosha

Bliss - Anandamaya kosha

Self - <USER2>

Even the grueling 200-hr Yoga training which some of my friends have endured is about doing all the poses (which can be quite difficult, especially if you are older and have something like a bad hip).

The 5 Koshas of Yoga: [http://www.swamij.com/koshas.htm](http://www.swamij.com/koshas.htm)

<comment><USER4> Perhaps because the "model" we have in the West of ourselves is more-or-less a dualistic model: mind/body. I guess that people in the West consider yoga involving poses to target the body and practices like meditation to target the mind. That would then cover "everything" as far as we'd see.

There is the notion embedded in Western culture that the seat of consciousness (which many equate with the self) is contained within the Mind somewhere. We have a mostly pop cultural understanding of the mind with a good dash of Freud-speak. I think that experimental psychology and neuroscience are increasingly important as sources of understanding for the mind.

In the West, also, I figure that wisdom is pursued through religion or the arts/literature/cinema/etc. or philosophy.

I think that most in the West see energy as part of the scientific domain of things. I realise that many don't but I'm going to discount this group as pre- scientific and/or not scientifically literate and/or superstitious.

I guess what you mean by Bliss is what the Buddhists mean by Elightenment? I can't think of a direct analog for this state in Western culture. If you could tell me more I'd answer this better.

Short answer. Western culture and science is resistant to the model you are putting forward. That's why. Be happy to debate any of this further.

<comment><USER3> Re: Bliss

I think it is along the same levels of Enlightenment.

"Our egos very often keep us from being our best selves" -Karen Armstrong

I think materialism is the short-term fix to some problems that we all have. Nothing is black or white. We are all consumers, in some form. I think true happiness comes from producing and giving more, especially when there is no monetary compensation or stress tied to the giving or producing. E.g. a _real_ hobby

<comment><USER4> Ah. In Western philosophy there is talk about attaining 'happiness' or even 'true happiness' but it does not surface much, I am open to correction here.

I totally dig Karen Armstrong, I have two of her books :)

I think Western culture is absorbing these Eastern ideas about not identifying with our thoughts and emotions, that you can acknowledge that 'you' (whatever that is) have thoughts and emotions but that they don't have to define you. I would be extremely interested in seeing if this way of thinking has been advocated in Western philosophy prior to now. Prayer in religion may come close?

An interesting advance on this I have seen recently is the social model of human interaction. By which I mean, we are not a duality: physical and psychological beings but a triad: physical, psychological, and social. To achieve 'happiness' or 'wellness' or 'enlightenment' or 'bliss', call it what you will (I know they are not strictly synonymous) that you'd have to work on all three: the body (exercise or yoga poses or ...), the mind (meditation or mindfullness or ...), society (? charity? other virtuous acts?)

Food for thought indeed :)

<comment><USER5> > In Western philosophy there is talk about attaining 'happiness' or even > 'true happiness' but it does not surface much, I am open to correction here.

It surfaces more in a _religious_ context; perhaps another East-West difference that is relevant here is the separation between secular philosophy and religion.

I was apprehensive when my wife dragged me along the first time, but that quickly changed. The classes are actually about learning the poses, not just doing them. For a beginner with no flexibility like myself it is perfect. The teachers walk you through all the different variations of the poses and help you along the way, so you can actually apply it yourself (properly) when doing it at home. There's also a level of trust for the teachers since it takes them years to become certified from what I've learned.

<comment><USER15> Some forms of yoga can be good for some people. And some of them can be quite bad, which isn't often acknowledged. There's a lot of dogma in the yoga community.

You can get around the login by using an Incognito or Private window, in Chrome or Firefox.

<comment><USER16> Here's my $0.02 on the subject. Every modern western yoga teacher (if they've passed teacher training) will tell you several things when you're starting out:

      1. If it hurts, don't do it.
      2. Listen to your body.
      3. You can not 'win' yoga.
      4. If you have an injury, use a modified pose.
      5. It's your practice, do it your way, at your own pace.
      6. Rest if you feel like it.
      7. Don't do everything everyone else does.
      etc

I've injured myself once so far. Most other people I know who practice regularly have also hurt themselves doing asanas, usually improperly. But the same goes for anyone who does a challenging physical activity, which yoga can definitely be if you push yourself or aren't mindful of your body. At the end of the day, there is no perfect way to prevent injury as all our bodies are different.

So unless everyone did the senior-citizen-modified poses there's always going to be risk of injury. Assuming a person could just jump into a crazy backbend like Vrschikasana without injury would be crazy... I don't know who you think isn't acknowledging this as every yoga instructor has probably also hurt themselves at one point or another.

The people who advocate yoga as healing or beneficial are not incorrect. But they're also not explaining to you _everything about yoga_ in one paragraph. People who read one or two sentences and stop learning are dooming themselves from ignorance.

Much like people who work out without a personal trainer, people who do yoga without an experienced teacher (not just practitioner) are going to be at a significant disadvantage. Perhaps the real issue is that most people don't acknowledge that yoga is complex and can't be minimized or simplified.

<comment><USER17> Yeah but injury while skiing or wrestling makes some kind of sense. Injury while sitting on a mat - something is not right there. Something intrinsic to the activity, if "there's always going to be a risk of injury".

<comment><USER16> When you're skiing or wrestling, you naturally engage a significant number of muscles and position your body to engage in said activity. When your whole body is in motion you instinctively flex your muscles to do things like balance, twist, bend, jump, etc. A body in motion is essentially in a more healthy alignment and supports your passive body parts (bones, blood, nerves, organs, etc).

When we are still and calm, our muscles relax (in general). This is basically a bad thing for our bodies because it stops the support that a lot of our body needs. For example, letting your neck sag forward or hunching over your desk over a long period of time can damage parts of the neck and spine, overdevelop your deltoids/chest and hurt your lower back.

When you're doing yoga asanas, this is all exacerbated as you intentionally put your body into positions that we don't naturally move into without lots of practice. So in effect, it's significantly more dangerous to sit on a mat if you're _not engaging_ your muscles or positioning your body in the correct way to support everything.

Yoga is dangerous in the way that every physical activity that requires skill to perform is dangerous, with one caveat: yoga asanas are dependent on the way you personally move your body and the state it's in. So really, it's only dangerous for people who naturally move their bodies in a way that might promote injury. This is why learning from a teacher how exactly to get into a pose, and practicing that regularly, is so important: it removes ambiguity and improves the entire physical act to not only be safe, but also be superior to how you might naturally do something.

But as a practitioner, I don't personally see how yoga is any more dangerous than skiing or wrestling. You can break an arm in wrestling, and a collarbone in skiing, if you're not careful. Just because sitting on a mat _looks_ easy doesn't mean it is.

<comment><USER17> I think it has something to do with hurling your body at 50mph down a mountain slope, that makes injury seem more normal.</comment></comment></comment></comment></comment></comment>

</comment></comment></comment><comment><USER5> The fun thing is that I found out that these 64-bit call gates are rarely used. Because it does not disable interrupts for example. Back when AMD was developing x86-64, they were probably focusing on Linux which did not use call gates.

<comment><USER6> The fact that call gates does not disable interrupts is usually the desired behavior. Linux (and NT for 32 bit code) does not use call gates because they are not that useful for OSes that target the Unix/C flat memory model. You can probably use call gates to implement particularly fast IPC mechanism with semantics similar to QNX's message passing. But probably only real users of call gates are DOS extenders and 32 bit windows for 32/16b thunking (which is to large extent the same use case of mixing 32/16b code in single process).

<comment><USER5> And yes, older Unixes also often used call gates too, for example Solaris.

Exceptionally gifted children: long-term outcomes of acceleration (2006) [pdf] - <AUTHOR> http://files.eric.ed.gov/fulltext/EJ746290.pdf <comment><USER3> I tutor some exceptionally gifted students as a side gig (for scale: calculus at 10, publishing research papers and learning graduate-level general relativity at 14), and I can say that the lessons of papers like these have been taken to heed. Today, there are tons of resources for kids like these, and the explosion continues every year. Professors are taking them for research projects, summer camps are bringing them together, and free online courses are spoiling them with knowledge. We're at the point where full courses are regularly put on Youtube in every field, with better teaching quality than almost all "real" courses! The kids seem to be quite happy for it, and I'm looking forward to the results in a couple decades.

My magnet high school was a smaller example of this. It had a reputation around the area for producing great outcomes for students with rigorous coursework, so people fought like crazy to get in. But once we did, we found that we had almost zero homework and spent half of each school day just sitting around. The real magic was in what we got to do with all that free time!

<comment> barry-cotter > I can say that the lessons of papers like these have been taken to heed.

This isn't true. Gifted and talented education receives maybe 1% of the funding that special needs education does, if that. In NYC de Blasio is trying to dismantle the existing system because the students are too Asian. Most of the US has nothing approaching that system. Normal high schools are at best indifferent to students who want to go higher than AP; they're certainly not going out of their way to help and encourage those capable of doing college work to do so.

Face it, at barest minimum 10% of 16 year olds could be in high schools like those associated with Bard College at Simon's Rock[1], where they graduate with an Associate's degree having completed half of the coursework for a Bachelor's. I don't know what percentage of 14 year olds could do the same or complete a Bachelor's before 18 but it's 100s of times greater than those who actually do.

[1] [https://simons-rock.edu/](https://simons-rock.edu/)

<comment><USER4> > maybe 1%

Honest question, not snide in any way: what would be the right percentage? Surely not 100%? Special Ed folks, folks on the left end of the bell curve for instance, need intensive one-on-ones. But folks on the other end of the bell would not need that same level of support?

(I'm not saying 1% is OK. And I understand that you pulled that number out of the air.)

<comment> barry-cotter Acceleration as of right instead of enrichment should be verging on free, requiring almost nothing in new expenditure. I'd be pretty happy with that alone to be honest. An early college programme like Bard College at Simon's Rock in every metro area with over 100,000 people with provision for boarding for those outside commuting distance wouldn't get you past 2% of education expenditure. That's under 10% of what's spent on special education. That would make me ecstatic.

<comment><USER5> It's not about how much money, but rather how to spend it. Well, okay, to spend money some way you first need it, but the amount could be quite small.

Most of the knowledge is already available online for free. (There are still some gaps that would be nice to fill, for example lessons for small kids whose first language is not English.) The problem is rather navigating the abundance of information.

First, to distinguish genuine knowledge from crackpottery. Like, most of us probably know that 99% of videos on YouTube containing "quantum" in their titles are pure nonsense. But a smart 13 years old kid doesn't know that yet, and can waste a lot of time gaining negative knowledge (misconceptions that later require time and work to unlearn). We know that in case of doubt, the materials published by MIT are most likely solid. For that kid, even this is not necessarily obvious; it would be better to tell them explicitly.

Second, lessons have prerequisites. I can find an interesting lesson, only to realize that I actually can't follow it, because it uses symbols and concepts I don't understand, and I don't even know how that missing part of knowledge is called. It would be great to have some guidance of form "you can learn X by watching Y, but first you need to understand M and N which you can learn by watching P and Q, etc.". A tech-tree of knowledge, kind of.

For these two things, you don't actually need a school system. A website could be enough: a page for each topic, internal links to prerequisite topics, external links for educational resources checked for quality. You would need some budget for this, but I assume that for costs similar to running one school, you could serve the entire nation. -- And it wouldn't be only for the smart kids; the average kids could use it, too. Everyone could progress at their own speed. Actually, it would be even better if all the kids would use it, because then you wouldn't have to look specifically for the smart kids and advertise it to them, they would simply learn about it from kids around them.

Now you can add extra services, like a silent place to go study if you don't have such place at home, a computer with an internet connection is you don't have one at home. Places to meet people studying the same topic. Etc. This all would be nice to have. I am just saying that the minimum solution that could help maybe 80% of gifted kids could actually be made very cheaply.

<comment><USER6> Aren't you basically describing Khan Academy?

It has good education material - including exercises - that you go through at your own pace, and is organised as a tree of learning.

Last time I looked it didn't go into university level subjects though.

<comment><USER5> Khan Academy is a great project. At least as a general idea; there may be some small technical details (there is some criticism on Wikipedia that seems reasonable, but maybe it was already addressed). I only tried it shortly, so I am not sure how complete it is beyond math.

Now if I may dream, I imagine something like Khan Academy, but:

\- containing all lessons from all subjects of elementary and high schools (and optionally some university lessons);

\- somehow certified by the state, similarly how textbooks are certified, so you would have some official statement saying "this is at least as good and as complete as public schools" (and if something specific is missing or not up to standards, the problematic topics would be clearly listed);

\- with the consequence that if you complete Khan Academy (and take extra courses/exams in the problematic topics), you would get a certificate equivalent to completing the elementary or high school (perhaps after taking an exam to check that it wasn't e.g. your parents doing the tests for you), without having to attend a school, and regardless of your age (so a gifted kid could have high school completed as 10 years old);

\- maybe with an option that teachers could upload their own versions of existing lessons or new lessons, and the users would by default use the standard Khan Academy videos, but could choose the optional ones, and based on popularity and administrator decision, the new videos could become the default ones; this is how the content could continuously improve and new topics (e.g. the university lessons) get added; also, repetition is the mother of learning, but instead of listening to the same video again, you could now listen to an alternative version of the lesson;

\- with some way to create an individualized study plan, so you could specify e.g. "I want to be a lawyer, but I also want to make computer games", and the lessons that lead you there would be highlighted.

Also, I'd like to see a competitor or two, of comparable quality.

</comment></comment></comment></comment></comment></comment></comment><comment><USER7> I remember some of my best memories were being in a GT program at my middle school where about 30 kids in my grade took the same core classes together every year for all 3 years. I didn't appreciate it then, but in hind sight being separated from most 6th-8th graders who barely care about school and being mostly around kids that did, had a tremendous impact on driving me through high school and college. Most of the kids were way smarter than me and are doing incredible things now.

Years later, when I studied in Sweden, I became great friends with a public school teacher there. I told her about AP classes, and GT and magnet programs and it was quite literally, a foreign concept. She said that in Sweden it would be discriminatory for children to be separated like that. I'm worried that the world is moving more and more in this direction, but I hope not!

I felt extremely lucky to be put around peers that pushed me and had shared goals because most of the kids where I'm from don't have that, and I could have easily ended up on a different path.

In college, I realized I was in an entirely different league when all of my classmates were in the top couple of graduates from their huge high schools, and I could barely hang on. Around that time I met a couple of 14 year olds in my dorm that were dual majoring in computer sci and math, and then I realized that there are so many different levels of intelligence in the same age buckets, schools have been doing it wrong for so long! In an ideal world everyone could be grouped at the appropriate level regardless of age, but then again, there is a huge difference in 14 year olds vs 18 and 19 year olds, so there seems to be some merit to the age bucket system. All that being said, the only thing I know is that world is a complicated place :)

</comment><comment><USER8> I'm currently 35 and I was ID'd as a gifted child, so this paper caught my attention. There's a section that discusses outcomes based on whether gifted children were allowed to skip grades or not, and my personal experience largely matches what is described for what would be my group, the nonaccelerands:

"Several of the nonaccelerands have serious and ongoing problems with social relationships. These young people find it very difficult to sustain friendships because having been, to a large extent, socially isolated at school, they have had much less practice in their formative years in developing and maintaining social relationships. Six have had counseling. Of these, two have been treated for severe depression. If educators were made responsible to ethics committees, as are researchers, such developmentally inappropriate educational misplacement would never be permitted."

I wonder how this group is doing these days. I wonder if the runners of the study ever considered introducing members of this group to the others to form a support group.

<comment><USER9> I'm 36, had a recorded IQ at school in the 180s, and was refused acceleration until I "socially adapted" to my classmates, which was challenging, as their interests (eg. football, wrestling, lads mags, pop music, sport, sport, sport) barely intersected with mine (eg. sciences, philosophy, coding, art, jazz & classical music). I was accelerated, eventually, but only by one year - at my prep school, I had been two years ahead, but I spent a regrettable year in the American "educational" system which meant I entered secondary school with my age cohort, as a commoner rather than a scholar, as scholarship exams were not available for overseas entrants at the time.

This was at boarding school. I was in detention incessantly, as I was bored out of my wits, and would do stuff like wandering out of an exam after 15 minutes, as I was done and damned if I was going to spend another three hours twiddling my thumbs, and I would disagree with teachers when they were flat- out wrong - that _really_ pissed people off - I wasn't such a blowhard as to vocally disagree over debatable or tenuous points, just factual error.

I would fake illnesses so I would end up in the sanatorium, where I would have time to read, and the opportunity to hang out with the several other bright kids from other houses who had established the same methodology for respite. Fond memories of hanging out in our dressing gowns, playing chess and having actual conversations with people I could relate to. Sadly, of the four of us, one is dead, one is in an institution, one is me, and the other survivor fled for the hills and writes children's science books.

School was an education in contempt. I remain convinced that the majority of people are idiots, with the equivalent of a flickering strip lamp for a mind, and nothing I see in the world around me dispels that thought. I am somewhat socially isolated - I have precious few friends near my age, instead most of them being three or four decades my senior - as, in similar fashion to my experiences at school, I have little in common with my supposed peers - <USER2> have not started businesses, or travelled extensively (package holidays to Marbella do not count as travel - hiking to Turkmenistan does), or stopped to think about the human condition. Older people of moderately high intelligence have at least had the time to gain some experience and perspective, and I can relate to them - but this means my "in-group" is scattered to the winds, and I see them annually at best.

Anyway. This member of that group is doing ok - I struggle with depression and anxiety, but a hyperactive 15 years has allowed me to exit the bullshit-mill and live the life I want - in the countryside, learning new things about nature daily, with mountains of books, and _time_ to do what I want.

As it happens, I made my escape with one of the few people I could relate to at school - moderately smart guy, somewhere in the 150s, but a hard graft type who brute forced his way to knowledge - admirable in his own way. We drifted apart after school, but fate or somesuch brought us to a nexus where starting a business together was practically inevitable.

In all honesty, if I hadn't been able to escape the manufactured world, I don't think I'd be writing this now, I would have killed myself by this point.

As to a support group - problematic. Part of the impact of being surrounded by idiots is to take your intellectual supremacy for granted. I find myself sparring with anyone remotely my equal, as my identity is inextricably tied to being the smartest guy in the room/building/city.

I do, of course, dissemble, and very, very rarely speak my mind as I have here - and I thoroughly expect this to be an unpopular post.

Prideful, no, but self-protective, yes - when there's no other social identity available to you you take what you can get.

<comment><USER10> How can an attitude of intellectual superiority amount to any good? I too was identified gifted (and while I've never had an IQ test I was probably never in the 180s) and while I share your frustrations with normies, dwelling on my _perceived_ intellectual differences with the world has done me no good. It certainly didn't help win me any friends. Being intelligent isn't all chess and quantum physics; there are lots of people in your ballpark that wouldn't come anywhere near fitting your description of a like mind.

I've found life to be much more enjoyable by intentionally avoiding people like myself. For highminded intellectual stuff there is plenty conversation to be had here on the net. Befriending and hanging out with a diverse group of misfits from all manner of backgrounds has proven to be much more fulfilling and while, yes, sometimes they can be stupid, and sometimes it is hard to find things in common outside of the reasons the group stays together, I've learned to see it as opportunities for further interpersonal growth.

If someone dedicates their life to filling their head with obscure knowledge they're just a nerd, no matter how much more intelligent they are than those around them. People may, collectively, be morons, but most individuals are surprisingly perceptive in at least a few areas, and while the prodigies in my life are indeed smart, I've spent enough time around them to know they would still be fish out of water for 90% of what life could possibly throw at them. I hope that your lamentations are formed _after_ you've sussed these qualities out of the folks you lament.

<comment><USER11> "I've found life to be much more enjoyable by intentionally avoiding people like myself"

Sure, that is a smart thing to do. That way, you can always feel superior, if you do not meet intelectual equals in daily life...

(I know, you did not mean that. I was a bit self mocking, whether this was sub consciously a decision for myself, but may apply to you, too?)

<comment><USER12> It's common though right? There worst thing you can do is tell a kid they are brilliant. They think they always have to be brilliant and escape hardship because it might mean they aren't brilliant.

<comment><USER5> > There worst thing you can do is tell a kid they are brilliant.

Other approaches also have their problems. I was raised in a very egalitarian spirit, and thinking of myself as somehow better than others was a taboo for me for a long time.

As a consequence, I had a few blind spots. For example, I noticed that in some situations certain kinds of people become hostile to me, for reasons I couldn't understand. I didn't know what I did wrong, and when I tried to be nicer or more open towards them it usually just made things worse.

Then one day a friend with good social skills explained to me: "They see that you are better than them, so they feel threatened, and they attack you to feel safer. And when you respond with kindness, that makes them feel even more threatened, because it seems their attack didn'd hurt you at all (although it actually did)." My mind was completely blown, because I didn't see myself as better, so I didn't realize others could see me that way. But the explanation matched the facts, for example that the hostility usually increased after I have succeeded at something (even something unrelated to them).

Also, the theory is that if you don't tell your kid they are brilliant, they will attribute their success to hard work, which will motivate them to work even harder. What happened instead was that people around me who didn't perceive me as brilliant, attributed my success to pure luck (because they saw I actually wasn't working that hard). So no matter how often I won the math olympiad, I was always told that I am not really good at math, that I merely got lucky, but soon the regression to the mean would teach me my place (and that if I actually understood math, I would know what "regression to the mean" means, and I wouldn't argue back). This was very frustrating, because it seemed that no matter what I do, people will find an excuse because I do not fit their stereotype; and that thought definitely didn't motivate me to work harder. (Actually, only now as I write this comment, it occurred to me that maybe I didn't fit their stereotype because perhaps I was smarter than the usual math-gifted kids they used to work with.)

I would recommend telling your kids the truth according to your best knowledge. Manipulation can backfire, even well-intentioned one.

<comment><USER12> I'm not arguing for manipulation, just the truth. But we have to realize that children are not small versions of adults. They have different cognitive abilities and processes than adults.

</comment></comment></comment></comment></comment></comment></comment><comment><USER13> Two main possibilities to match the curriculum to the needs of highly gifted children:

1) Put them together in a special class composed entirely of students with similar level of giftedness, taught by specialized teachers using a gifted curriculum.

2) Move them to a higher grade, which means they will need to study with (possibly much) older students.

Option 1) is superior for their social development since they are not more mature in all respects. It should be pursued whenever possible.

Option 2) may also subject the kids to bullying and jealousy by their older peers, some of whom might do worse than the gifted one in many academic subjects despite age difference.

Early grouping by ability is also more desirable. From the paper:

"In both Australia and the United States, schools tend to delay acceleration and ability grouping until the middle years of elementary school. This policy is fundamentally flawed. It is in the early years of school that we should be identifying exceptionally and profoundly gifted children and developing programs of acceleration and grouping to provide a more effective response to their accelerated intellectual and emotional development."

It is in the interest of society to develop highly gifted students fully since they have more potential to invent groundbreaking technologies or contribute to society in an extraordinary way.

Source: I have taught many gifted and highly gifted students over the years.

<comment><USER14> There is another option that would be progressive "inclusive" approach: allowing more flexibility in teaching content and materials so that teachers can provide different exercises, challenges, etc to different students in the same class. This is a matter of having a trust-based (rather than Control- Bäder) system with highly qualified teachers and high autonomy for those teachers. The evidence indicates that all - gifted, special needs and any other students and teachers which enjoy increased autonomy. This is the approach in eg Portugal, Finland, Estonia, Norway, ...

<comment><USER15> This is not how it's done in Norway.

</comment></comment></comment><comment><USER16> This always leads to discussions of "what kind of school is right?" and not of "is school right?"

Perhaps the answer is always yes, but it'd be nice to see it discussed.

Marcus Aurelius said 2000 years ago to "spare no expense on private tutors" \-- this is going to be cost prohibitive at the very least, but it's also worth thinking about.

Another thing worth thinking about is every extra minute you spend building another this-or-that at work and not with your kids is an advantage you give your employer while simultaneously depriving your kids of your care, knowledge, and enthusiasm for subject matter (to a degree). There's a balance to be found, of course, but it's something I imagine people struggle with. Work always wants one more thing, but it can wait until Monday.

<comment><USER17> > Marcus Aurelius said 2000 years ago to "spare no expense on private tutors"

Taking parenting advice from people thousands of years ago is not the wisest idea. Let alone Roman child rearing advice. Let alone from an emperor. Let alone from Marcus Aurelius. His son, Commodus, was one of the worst emperors. I'm not saying that Aurelius was wrong, but his record on child rearing is clearly terrible considering the lives of his children.

Getting into working more or less for the benefit children is very individual. Each family is unique and changes over time. You raise your kids, yes, but they raise each other and themselves too. They are real people too.

<comment><USER16> Sometimes we draw a bad hand, and no amount of parenting can save some of the mentally disturbed, like Commodus -- you can't read Meditations, though, and say it's not full of startlingly relevant advice to modern life. From education to work ethic to reflective, thoughtful consideration of one's actions, to coping with trauma.

Also, that isn't Marcus Aurelius theory on parenting, he said he learned it from his grandfather, which eventually led to him being one of the Five Good Emperors, so how does that change our analysis?

Anyway, pretty much every single study ever done says the smaller the class, the more direct the instruction, the better the academic result, from 0AD til 2020AD, the way we're wired hasn't really changed.

It's not likely that receiving 1/30th of the attention of your teacher is going to be as valuable to you as 100% attention, or 50% attention, or 25% attention, vs 3% in a normal school.

If kids raising themselves and each other was reliable, we wouldn't have disadvantaged youth. Poverty means busy parents (2 jobs, etc), busy parents mean less time with the kids. It's going to be hard to convince anyone that more time with your kids is going to be anything but beneficial.

<comment><USER17> Commodus was not the only sibling with a checkered life, the family was wracked against wealth and privilege. Again, the parenting advice of Roman patricians is not necessarily wise advice. And yes, some of _Meditations_ is great stuff, but some of it is also mediocre, and some of it is bad or just wrong. We've had 2k+ years of new work done in stoicism and other philosophies.

Each family is unique and spending more time with a tutor or parent is not always the best. There are ~7.5m reports for abuse of children in the US annually and ~65k cases of sexual abuse of children. There are ~75m children in the US total. Each one of those cases, horrible as they are, are real and society needs to take them into account. It's nearly 10% of kiddos that get abuse reported annually. Digging into these grim statistics is very worthwhile. [0] Hand-waving them off is not helpful or realistic to most educators, parents, or policy makers.

I'm _not_ saying that larger or smaller classes are more or less ideal or that abuse is related to stoicism or families. I am saying the solution is unique to each child and that many solutions exist simultaneously. Each family and each person is unique.

She used this term because she worked in a highly competitive district where parents were constantly harassing her to consider their children "highly gifted". Once she used this term, it became easier for parents to accept that their children were doing fine in "normal" class, which was quite good anyways because of the average aptitude of the students.

<comment> barry-cotter > Once she used this term, it became easier for parents to accept that their > children were doing fine in "normal" class, which was quite good anyways > because of the average aptitude of the students.

Your child could be doing work three grades ahead, learning things that would challenge them and help them grow intellectually. Instead we'll keep them here with the normal children where at best they'll learn to shut up and not bother the teacher.

<comment><USER19> The GP is talking about competitive parents whose kids aren't genuinely exceptionally gifted. The parents are just looking for bragging rights and/or another edge.

<comment> barry-cotter Keeping children who're perfectly capable of doing sixth grade work doing fifth grade work isn't as bad but it's still a waste off their time and a lesson in the actual priorities of the school system, which certainly don't have learning among the top five.

<comment><USER19> Some parents don't really have the best interests of their children at heart. "Hot housing" children does not make for better future outcomes. It just deprives children of their childhood.

<comment> barry-cotter > "Hot housing" children does not make for better future outcomes.

I would welcome any research to that effect if you have it to hand. I am not an expert but if you search gwern.net for "gifted education", "acceleration" "SMPY" or "Study of Mathematically Precocious Youth" you'll find many papers on this general topic. There's nothing there showing negative effects and quite a bit that's positive.

<comment><USER19> It's a term coined by researchers and I believe it was used in the name of a book at some point. I can't readily find the book, but I found this article:

[https://www.verywellfamily.com/hothouse- children-1449187](https://www.verywellfamily.com/hothouse-children-1449187)

I was briefly Director of Community Life for The TAG Project and was a low level presenter at, I believe, a Beyond IQ conference one year a long time ago when my kids were still kids. I'm fairly familiar with the research.

Yes, holding back kids that are actually gifted is harmful to them. So is putting a child on a treadmill to satisfy the ego of the neurotic parents.

<comment><USER20> No. It isn't fundamentally harmful to children. It depends on how it's done.

One of the major differences between effective programs and harmful ones are the attitudes of the children in those programs. Both the hothouse parents described, and programs for kids "behind standards" push really hard with rote learning, high-pressure, and often punishment. On the other hand, effective programs, both for kids ahead, behind, and at grade-level have richer activities which build love-of-learning.

As a footnote, I looked at the web site you linked to. It cites a bunch of widely discredited Piagetan nonsense.

</comment></comment></comment></comment></comment></comment></comment></comment><comment><USER21> > If educators were made responsible to ethics committees, as are researchers, > such developmentally inappropriate educational misplacement would never be > permitted.

This is a recurring theme. For example, when doing education research with a control group. Sometimes, while the study is still in progress, the benefit of the intervention becomes so clearly dramatic, that by IRB standards, continuing to deny the intervention to the control group becomes ethically fraught, suggesting the experiment be stopped. Even though by education standards, the intervention is unlikely to be widely adopted any year soon.

Similarly, part of why science works, is researchers' fears of being embarrassed in front of their peers, by getting things carelessly wrong. This doesn't always exist - my favorite example being astronomy education content that gets the color of the Sun wrong. So there's a question of what community characteristics are needed to support it.

Awareness of ethical issues in education, such as "equity", seems greater now than in decades past.

So looking ahead, might a perception of embarrassment, or of ethical failure, be encouraged and leveraged to improve content and pedagogy? And what might that look like?

</comment><comment><USER22> I wonder a lot about how much giftedness matters, for children below exceptionally gifted. My IQ was measured at about 150 twice, at age 3 and 15. I am definitely not exceptionally gifted - I was able to be on the cusp at some programs that had exceptionally gifted participants and I was in awe of them.

But as an adult I've never really felt limited by intelligence, but instead by motivation and social skills. So I don't know what to stress for my children. I was deeply unhappy through public school. Would I have more motivation and better social skills if the public school had been less boring and had less bullying? Would I just be more of a jerk?

My kids are in early elementary, and they are also not exceptionally gifted, but they are easily 2-3 grade levels ahead in math, and a little ahead in reading. The other stuff at school could certainly be better for them, but in ways that I suspect would be better for all the kids there.

I think I'd be happy with their school if they had more recess, the kids were nicer and the math were more advanced, but I don't know where to find that for them.

<comment><USER23> I was GT in my very mediocre public school - shit was still hard for me, academically. I got a B in calculus 2 in high school. I constantly feel limited by intelligence and social skills (which harms motivation). Most of this thread is just bragging - "dumb" people like me don't get the benefit of the doubt and don't receive any of the societal benefits either.

</comment></comment><comment><USER24> Can anyone recommend any tried and true, globalist/international perspective distance education / homeschooling groups? Less focused on base academic outcomes (assume this is covered), more focused on co-exploration and organic learning with distributed friends in a semi-structured or periodically adult- stimulated fashion. We don't need to download rote learning worksheets or lesson plans, we'd prefer to explore real world subjects freely, asking questions and allowing one subject to function as a lead-in to others. Unsure if this exists.

</comment><comment><USER25> I can relate to studies like these in many ways.

Growing up in India, I faced a hell lot of issues. At the age of 2, I was able to remember names and faces of all my relatives, at 3 I was able to read fluently. By the time I was 5, thanks to my relative I was made to repeat a grade because I was born on a certain month. By 9, I was able to do 10th grade math with ease. My mom observed this and asked the school things can be accelerated. I was placed in 10th grade and just got myself bullied. School's verdict was I was that I am socially inept and hence I must have cheated to solve 10th grade problems. School saying that broke my mom's heart, and mine. I was eternally depressed (was not aware of it though) from then onwards till college. Throughout my school life all I faced was bullying cos I don't share the same interests as the others.

College wasn't any different. I grew up watching OCW physics and thought college would be similar. Turned out wrong. I have ruffled feathers with every faculty there that I wanted more work, to be challenged more. And all I got was "you should be more humble and patient. You should wait for the other students to catch up. Go with the pace, don't run, walk. blah blah" After 4 years, I came out as a person with no motivation, mentally lethargic, depressed, just wanted to coast through life. It had been hammered into me that _I_ was the problem, not the system.

Thank god I met my wife, we both were very similar and had experienced very similar situations in life. It took a long while to understand that the problem is not me. We identified as gifted children, reading up on articles, matching traits. My mom regrets that she didn't know about any of these "gifted stuff". All of us recognize the negative intentions of the people who grew up / lived with us. Both my wife and myself are trying to get back into the groove, finding ways to challenge each other, to learn to work hard, to motivate, to get back the lost years from when we could have been accelerated. Hopefully we catch up on time.

I am positive that my kid will most probably be a gifted child. I will be doing everything in my power to take care of him in a proper manner.

I relate to so many people in this and many other threads in HN. You all have my deepest support and sympathies for your bad experiences. Please don't let go of life. You can still be the smart person you once were. Being smart isn't being entitled, it's just who you are.

<comment><USER26> What will you do if your kid isn't a gifted child and falls below your expectations? Hopefully you'd still love them and treat them in a "proper manner" right? Just be prepared for that very possible outcome.

<comment><USER25> I'd still love them. I really hope I didn't imply that in my comment. The kid would just be surprised to have quirky parents when it is very "normal". In the end we'll just be a very happy family.

</comment></comment></comment><comment><USER27> A lot of people in this thread thinking they are Terrence Tao, Karl Frederick Gauss, Leonhard Euler, John Von Neumann, etc. Nope you don't have the faintest idea of what it means to be exceptionally gifted.

<comment><USER28> ... have you known any of those personally?

<comment><AUTHOR> _'... A bunch of hype probably inspires you to deliver a little more, but beyond that it seems pretty risky ...'_

Maybe they don't want to release because they know how much _more_ they have to work on it. So far the biggest thing I don't see yet is a feedback mechanism ie: usage. Do they do have a beta program that someone has signed up & used?

Spock could also learn from this. My favourite feature in spock is _"add an acquaintance"_ If you select a name (any name because there is bound to be others with the same name) and they don't have a photo, your forced to add by name alone. 9/10 times it's the wrong one.

The main (official) reason for the new cable is to decrease latency and costs, and also to decrease the almost total dependency on the US links.

Ask HN: How much do you put in your 401k? - <AUTHOR>

I'm 25 yo with a CS degree from a top school in the US. I have plenty of experience and I don't think I'll ever be out of a job or not want to code for a living.
A lot of people my age, in a similar situation, tend to not put any money into retirement savings.
I think part of that stems from the skepticism we millennials have about the uncertainty that the future holds, stock value, etc...
i.e. "Why should I put in 6-10% of my salary when I don't know what 25 years from now look like?"
Personally I'm putting in 6%, but I can probably do 12%.
I'd like to know what other people's stance on this is.
Are there better ways than a 401k to invest 6-12% of my salary? <comment><USER2> The most important bottom line is: Maximize your employer's match. Whatever the maximum match you can get from your employer is, go for it. That is money that is a part of your salary plan that you don't get at all if you don't contribute your share of.

Beyond that, a good 401k Provider is going to give you the option of HOW you invest that money you are "forced" to save. It's a stock account that you ultimately own and control. The only difference between that and say a Scottrade account you set up on your own without your Employer's involvement is the way taxes on your 401k work: Money that goes into the 401k is BEFORE your income taxes are calculated and if you manage to wait to your retirement age to withdraw from that account you NEVER pay income taxes on it. (This is why there are people that try to minimize their income taxes by maximizing their 401k contributions as much as they can afford...)

That said, you can withdraw from your 401k at any time if an emergency were to happen and you need access to those funds. It's your money. You just have to be sure to set some aside for Uncle Sam and the IRS when you do. (A good 401k Provider will even help you with that.)

I am not a Accountant, and you may want to ask one for specific advice for your lifestyle, but I had the same question when I was trying to figure this stuff out at 25. Hopefully this helps.

</comment><comment><USER3> "Why should I put in 6-10% of my salary when I don't know what 25 years from now look like?"

To me that's even more of a reason to put money aside. in 25 years social security may be bankrupt.

I personally put 10% aside in addition to the employer's match (so in effect 13%) and I'm 28. Note that there is a yearly limit (somewhere around $15,000 I think, not really sure).</comment>
