"And so it happens that the person who reads a great deal — that is to say, almost the whole day, and recreates himself by spending the intervals in thoughtless diversion, gradually loses the ability to think for himself; just as a man who is always riding at last forgets how to walk."

There's nothing inherently insecure about a smart lightbulb. With studies like this proving the danger inherent even in a 100% perfectly secure bulb, then yes, people likely won't attach them to secure networks. _Without these studies_, they would, because nobody would know of any dangers.

You're thinking too current. There's no reason why an "industry" smartbulb won't exist in the not too distant future, with hardened security and professional use cases. This study is flagging up that even with hardened security there are new attack vectors.

Heritability of IQ is the term you're looking for. Wiki has a page on it here [1]. The numbers have not been pinned down and it was previously thought to be as low as 57%, but recent studies tend to show heritability rates upwards of 80%. There are a lot of complex issues that make study difficult. For instance there's the paradoxical issue that childhood IQ can be somewhat meaningfully influenced by environment, yet that notwithstanding, as children approach adolescence and especially adulthood their IQ becomes ever more a product of genetics.

That said environment obviously does play some role, but that role is already a minority player and seems to be getting smaller as we learn more about genetics.

It's an interesting phenomenon, perhaps worthy of study by propagandists or advertisers. If you tried to claim that a person's physical strength could be measured with a single number people would think you're mad, and probably most people in the world would think the concept of "IQ" is mad, and yet, in some countries, so many people believe in it.
> In social science research there is often a tradeoff between measurement quality and sampling quality. Do you want to measure your variables really well in a small sample, or measure them crudely in a large sample.

Wouldn't it be honest to just accept the fact that both methods don't provide data that's relevant and trustworthy enough for the research at hand? It sound irresponsible to draw conclusions (that will be picked up by newspapers and eventually policy makers) based on data that does not merit them, only because no beter data is available.
But the point isn't to develop skill but see your brain natural talent of resolving complex problems, mastery of one own psychology is advantageous also.
The property you want is beyond robust. You actually want the algorithm to constantly go beyond its comfortable prediction range and "fail" repeatedly. That's how you learn.
I don't understand either. If you have to write in C, and you have to compile, what's the advantage?
Fluid and crystallized intelligence (which is what IQ test measure) are the most robust ways of measuring intelligence, and IQ is the single most reliable metric ever discovered in psychology, in terms of making predictions. If you're interesting in measuring how smart somebody is, there's no better way of doing it than with that single number.
That is mentioned in the article, full separation is required on any road where the speed limit exceeds 30km/h (~20mph).
> Chen said air pollution was most likely to be the cause of the loss of intelligence, rather than simply being a correlation.

Why? You can't just say that and expect people to trust you. The fact that they followed the same people may reduce the chances of certain DNA traits having an effect but how does that rule out other commonalities in environmental conditions. If you're in a polluted city it seems likely that you're in a large city. So do all the common traits of a large city also reduce your intelligence?

I want to read the study but I don't want to subscribe. If there is logical proof in the study that this is not simply a correlation, the guardian piece does not represent it.

Why don't people start more private schools if their capacity is maxed? By assumption, there is more demand than supply, and the vouchers would increase the demand further.
Are there any good books about ideas or a history regarding how societal values and technological tools of the parent generation has influenced their children?

How did the philosophical insights of e.g. Kant or Humboldt influence western consiousness, and how did that influence the growing up period of the generation that followed, and what were some reasonable consequential attitude updates when those children grew up into adults?

It'd be interesting to see if there are models or any reasonable patterns that can be seen in the adult world view -> child upbringing and subsequent next-iteration adult world view, and what that might say could happen (or might not happen, contrary to what we suspect will happen) about the current generation of gamified children growing up with trump in the background.

> LiteTree is more than TWICE AS FAST than normal SQLite on Linux and MacOSX!!!

In my experience, claims like these usually end up showing that the author didn't understand the `PRAGMA synchronous` setting at all, or they chose to ignore it to juice their stats.

In this benchmarking test are the data durability guarantees the same for both LiteTree and vanilla SQLite?
What's really amazing to me is when you realise that the UK executive and legislative branches are based in London. MPs, Lords, and often their partners and children are all living and working in an extremely polluted environment for years on end. Even so, with the knowledge that they are seriously harming their own health and the health of their closest relatives, they persist in resisting and blocking attempts at actions to improve air quality in London.

Whenever somebody defends the quality of democratic representation in the UK, I just remind myself that these are people who would rather they and their own children suffered illness and premature death than take action that might piss off business and motorist lobbying groups.

It sounds like nested error handling will be the abnormal case and the "default" error handling will often be normal. That is, all you will notice in common use is that the boilerplate "if" is replaced with a "check".

It also sounds like the nesting does not escape the function itself. It always either returns error, or doesn't.

"!g" is a fallback, not a default action. Seems to me pretty reasonable. Using it you're actually skipping ddg, not using it.

IQ tests are not generalised measures of innate intelligence at all and your IQ absolutely increases with education.

My girlfreind is currently doing a doctorate psychology study, of which a small part is a standardised IQ test (though I dont know which standard; there are several). She asked if she could practice the process on me.

There are several sections, but to pick 2.

For language acuity, I scored OK. This section basically asked you to define a series of given words. Your knowledge here absolutely would change depending on your environment, job and education.

For pattern recognition, I scored fantastically. But I know this is because of years of studying geometry in math classes. I know exactly what my thought processes were, "Count the vertexs, count the edges, count the bisections, are some things odd, are some things even, do some things add together, do the shapes mirror once/twice, are they rotated". I know exactly where I picked those ideas up.

In the UK you can drop Maths and English/Creative Writing at 17. If you finish a pHD at 26 you havent regularly explored those ideas in near on 10 years, but you absolutely could still achieve it, so I do think its a better measure.

Sure, but much of that process isn't customer facing. I tend to draw inferences when I read "website" as opposed to "web application".
I prefer the bottoms up expense buildup of people as opposed to a broad percent of total calculation as it introduces more discipline to the forecast and reduces risk of weird situations where sales go up by x% and all of a sudden you’re hiring 3 half people (in models I expect to see expenses go up in steps because that’s how they work in practice). Also gives insight into the mindset of the forecaster. For example do they assume 2 sales people can cover 300 accounts while building a pipeline without SDRs? I am an operator, not a VC so perhaps it’s an audience preference.
Speculation: Assuming the VM has no bugs it is sandboxed. The code run can't access the file system or freely allocate memory. Thus code from less trusted sources can be executed.

If there's one thing in the field of psychology that is actually science, it's IQ tests. Empirically, IQ has been shown to not change much at all over time, and is the single most reliable factor for predicting outcomes that psychology has ever produced. The big 5 personality model is the next best tool psychologists have, but it's not nearly as reliable as IQ.

That said, it's still not an excellent measure for basing predictions on, by the standards of "traditional" science. But if you don't put any weight in IQ, then there's nothing in the entire field that you should have any faith in.

Could this all plausibly be explained simply by buyer's market vs sellers's market for the respective jobs? I mean: if there exist far less good programmers than demand for them on the market, employees will easily become entitled (side story: for example in Germany, the job market for programmers is very different from what I read about the situation in the Silicon Valley on HN). On the other hand, if employers have lots of potential employees to choose from, the power dynamics is entirely different.

Because a tape is relatively cheap, the drive is not. With a hard drive robot you lose the (small) cost of a SATA/SAS controller per drive, but you add the cost of the robot. If you're going to get disks you might as well just hook them up.
Valuable Lessons from My Second Year of Freedom
You can't teach this in the classroom: it's not school's mission, plus it sometimes goes against its agenda.

Teaching this can only be done by somebody close to you. Family or friends.

However, two conditions make it rare that it happens: said relatives must know about it, and they must be willing to teach it.

Very few people actually know about this: either they do it without understanding that they do it, or they don't do it. It's a rare combination to have somebody acting in this way, and understanding deeply the ins and outs of it.

As for the will: teaching it means it does not go against the person agenda. It means the person must have the ability to teach. And the desire to invest the time and energy to do so, as it's a long process that involves patience, failure, and a lot of leading by example.

Bottom line: it's hard to be a good parent. Damn it, who knew?

However, if I decided to teach it to somebody (I decided not to have children), I wish I would be able to do do the following thing:

- Be extremely honest. Half of the problems in this game is about all the lies we tell each others. That adults are always right. That schools is always here to help you. You have to be nice. They are wrong and you are right, or vice versa. Justice exists outside of the human mind. Being a child is easy. I'd talk about the pain I had, I listen to their pain.

- Talk about cost. A lot. Social cost. Punishment. Long term consequences in life. Being hurt. And hurting others. This must be demystified. It's not something special. It's life. It's ordinary. It's not the end of the world and it's the same for everybody. You can find happiness between those. But you need to make conscious choices about the costs, and not let them happen to you.

- Be patient. Accept failure. Talk about it. My father used to double anything the school would punished me with. So basically, if a bully kicked my ass and I defended myself, I would pay 3 times for basically minding my own business. This is the opposite of what you want.

- Teach about basic grooming, fashion, language and social conventions. Show them as tools instead of constraints. You can change clothes and wording to match occasions: formal when needed, fashionable when required, personal when with loved ones. Once you master them, you can actually use them less and less and be yourself more and more without friction. Life is funny that way. But as long as you reject them as artifact of our sick societal system, they will be a burden to you.

- Have the "boundaries" talk. How to respect others. How to make others respect yours. By body language. Verbally. Physically if needed. It's weird to have something that artificial to deal with, and so it's even more important to highlight it.

- Lead by example. Speaking only helps so much. You must show. And involve.

"after one week of exciting sleepless nights of work (which explains the lots of typos you will found ahead), the darkriscv reached a very good quality result"

Not commenting on the actual quality of the code, but I wonder how can one make typos due to sleep deprivation, and yet produce "good quality results" in software.

>But we shouldn't act as though high packet loss rates at the IP layer are to be expected, they are avoidable. And fixing them will do a lot more than just enable HTTPS to work better.

At that distance the very physical latency limit is almost a second. You can literally not go below. The high latency will have a lot of protocols simply time out or consider the packet lost.

At that distance you need some well engineered ground equipment to handle the signal losses. A dish and a high powered transmitter that need to be within a degree of the target. If you're off by a degree you're likely going to hit very bad packet loss. A degree is not much and you could be cause by the ground below stretching and twisting over the day due to temperature changes. TV doesn't have to deal with sending data up the link other than using the massively more powerful and expensive dishes from TV networks.

Lastly, from ground to geostationary orbit you may find that your 40MHz band is full of crap. Not because someone else is sending but because you're sending through a solid belt of radiation and magnetic flux. You'll find that for a wide range of bands they either suck at penetrating the atmosphere, penetrating the magnetic field or get sucked up by interference from half the universe.

The layers above IP have ways to handle packet loss for a reason (although the reason was bad copper cables and bad MAC). Also, the MAC is another problem; you're not the only one who wants to use the very limited resources of the sat. One of the most common and effective forms of bandwidth limiting is dropping packets and it's normal. Packets drop all the time, every TCP connection drops packets. It happens and almost all protocols deal with it on one level or another.
Not OP, but worked in science before. What you want is not to work in science on software dev ;) Scientists usually write extremely ugly, messy code, just to make it working and finalize paper for publishing. Remember, their focus is paper not code nor properly workable program.

Things like testing, agile, tickets, code indentation, patterns - none of that you'll find there.

If you aim for serious environments like Wolfram Research or MathWorks, that could be different. If you aim for quantitative firms, usually you'll find there scientists writing prototype in mathematica/matlab/r/python (messy again) and devs who will re-write it in c/c++/java/asm.

I've been followed home and threatened in the US for giving a driver who was tailgating the middle finger. Are you saying that in the UK this would never happen? I certainly wouldn't risk provoking random strangers, especially those who are not following traffic codex.
There's a bunch of emotional exercises/practices that enable you to connect with unresolved traumas held in the subconscious mind, learn about what they are and how they're affecting you, and let them go. Which as far as I know is what MDMA enables, but they don't require you to have access to MDMA, and are safer for frequent long-term use. The practices all work in different ways too, so I'm sure they enable you to have experiences/insights that are quite different to what MDMA activates.

Some practices I'm familiar with include Holotropic Breathwork (developed by Psychiatrist Stan Grof, who was a pioneer of research into LSD before it was banned), EFT/tapping and Milton Erickson Hypnosis. A friend of mine frequently does Family Constellations workshops and finds them highly beneficial, but I haven't tried that yet.

There are others that are more left-field than I'm willing to go into here but you're welcome to email me (address in profile) if you want to know more.
Three or four man college teams do cubesats all the time, so I’m guessing it’s entirely doable by an individual. In the US I know you have to get FCC approval, and do so you’ll probably need to plan on an orbit with a short lifetime.

"The new work [...] analysed language and arithmetic tests conducted as part of the China Family Panel Studies on 20,000 people across the nation between 2010 and 2014. The scientists compared the test results with records of nitrogen dioxide and sulphur dioxide pollution."

While I admittedly did not read the science paper, the newspaper indicates that they used test scores as the actual number, and the "cognitive drop equivalent to one year of education" phrase is just a way to explain the results, presumably anchored by how people in different school grades score in those tests.
I have on online.net and vulr. The problem is backups and autoscaling. If you know your work is constant and you have a cloud based backup that can spinup, then you're fine. Otherwise, you run the risk of going down due to anything from running out of bandwidth, RAM, etc.
