> I meta-analyze the >19 studies up to 2016 which measure IQ after an n-back intervention, finding (over all studies) a net gain (medium-sized) on the post-training IQ tests.
The size of this increase on IQ test score correlates highly with the methodological concern of whether a study used active or passive control groups. This indicates that the medium effect size is due to methodological problems and that n-back training does not increase subjects’ underlying fluid intelligence but the gains are due to the motivational effect of passive control groups (who did not train on anything) not trying as hard as the n-back-trained experimental groups on the post-tests. The remaining studies using active control groups find a small positive effect (but this may be due to matrix-test-specific training, undetected publication bias, smaller motivational effects, etc.)
I also investigate several other n-back claims, criticisms, and indicators of bias, finding:
payment reducing performance claim: possible
dose-response relationship of n-back training time & IQ gains claim: not found
kind of n-back matters: not found
publication bias criticism: not found
speeding of IQ tests criticism: not found

On the other hand carbon chemistry is the center of expertise for biochemists. They hardly know anything else.

As well, carbon chemistry is rich under earth conditions (temperature and pressure wise). We simply don't know for others.

Carbon is an essential building block to life and everyone seems to be against it which seems quite alarming. Without carbon the earth would look at lot like mars, and judging by most of the polices the elite seem to be pushing, that's really what they're aiming for.

>Higher carbon-dioxide levels will be beneficial. CO2 is an essential nutrient for land-based plants. The Earth’s biosphere has also experienced a relative CO2 famine for many millennia—the recent increase in CO2 levels has thus had a measurable, positive effect on plant life. Future CO2 increases will boost agricultural productivity and improve drought resistance, thereby bolstering food security and contributing to a greener, lusher plane

I used to do this bit back when i did standup comedy a few years ago, it was about how marijuana was a gateway drug and i went on to say the real gateway drug is oxygen, because think about it, without oxygen none of us would even be here, or to even get a light. So i went on about how if we really wanted to have a war on drugs we would have to nip it in the bud, and eliminate all of the oxygen on the earth.

But it seems to me that they had already jumped the gun and thought a further step ahead of me on this one, think about it, what produces oxygen? Plants, and what do plants absorb to produce oxygen? Carbon. you eliminate the carbon, there's no oxygen. quite genius when you think about it, and you get a bunch of people who want to seem like they're a bunch of do gooders and jump on a bandwagon everyone seems like is for a just cause at first glance without spending as so much as five minutes thinking about it. and really that is a dangerous thing to do, blindly follow narratives.

and the fact that this is being pushed by a company founded by a known eugenicist who wants to reduce the population of the world, "for the greater good" and it still isn't raising eyebrows, speaks of in itself.

It's becoming abundantly clear the real innovation from on-demand services (including ride-sharing companies), is their ability to transfer more money from labor to capital with complex pay structures. For many if not most of these companies, its their only means towards profitability. For instance, any rise in revenue Uber experienced in the last 3 years was exclusively due to cuts in pay for drivers. Tech has long lost the glow that prevented the public from scrutinizing whether a VC subsidized, underdeveloped business model is good for society. So far the answer seems to be no.
I remember seeing a list of domains which Firefox tracking protection explicitly whitelists (presumably to avoid breaking these sites’ functionality). Google and Facebook were in there. That told me all I needed to know about this supposed tracking “protection”.
actually, Linux uses at least two of these:

for security reasons (ASLR), the vsyscall page is implemented on modern kernels by unmapping the page, trapping the page fault, and emulating the system call.

the recently introduced io_uring interface provides an interface to set up a buffer ring which is asynchronously polled by the kernel for system calls to execute.
AirPods do seem to be popular.

They are a product I have no use for, and the way people leave them in constantly appalls me.

But, I must admit, friends who have them are impressed, and at least one has given me good reasons why.

So, AirPods serve as good evidence against my belief.

Of course, the reason I don't use Chrome is due to the stuff Firefox has - ad-blocking on mobile and tree-style tabs on desktop. Chrome's look and feel is specifically what I don't like about it.

It's more of an elaborate answer to the infamous ftp comment from when Dropbox did launch in 2007 here on HN (https://news.ycombinator.com/item?id=8863). At its root, the project tries to solve the Dropbox problem by abstracting the storage aspect so that you can bring your own backend by implementing a simple interface.

If California wants to prevent growth and keep repeatedly shooting itself in the foot for decades to come, it's a choice. It makes that market less competitive.

Removing the repos seems to be a bit much especially since he is planning on making them private and then deleting them.

Why not just leave them in place if you're burned out and see if anyone is willing to take over maintainership.

Impact assessments are generally contracted out via RFP.

As a government contractor myself, I have no confidence that a random environmental impact assessment has any semblance of reality to it. It's a crapshoot as far as which contractor is selected and if they focus on the right factors and come to the right conclusion.

Except that Firefox Preview in my experience is not. It's even quicker than Chrome or Bromite on my FP3.

Fair enough. Things are not black or white after all. There's infinite ways you can give feedback;
Just as humans require a differently level of manure and water to plants, we are also at our best with a different level of CO2.

The optimal CO2 level isn’t even constant between plants, but at the upper end “good for plants” is the same as “makes humans 25% worse in memory speed/accuracy tests”.

Sounds like the maintainer writes a lot of code using rust's "unsafe" keyword, and regularly gets issues raised about this (and versioning, and some other bits).

This last issue, which included a patch, has pushed them over the edge after it descended into disagreement.

Net/net they were repeatedly asked to change coding style, didn't want to, and have decided it's better to just avoid the arguments by not publishing code.
Sealed nuclear reactors [1] will likely play a big role here. They are much safer and far less expensive than nuclear tech currently in operation (which dates back to the 70s or earlier). The astronomical cost of building a nuclear power plant has been a huge barrier to adoption, but that should come down significantly over the next decade.

That’s what I’m getting at. Airport drives are usually the best, but if you aren’t told the passenger’s destination you could be forced to go all the way out to the airport to accept a tiny fare.

Great for me as a consumer; lousy for the driver’s income; and a reason why (to answer the question asked) some drivers / riders accept loss-making fares: they don’t get told in advance how much the trip is worth.

Based on some quick Googling, it looks like the pass band they used for voice (at least for Apollo) was 300Hz to 2.3kHz. Assuming that filtering was being applied in the audio gear and the RF side of things was a bit more permissive, that would allow them to keep the control tones outside the range of any vox transmission.

Compare a typical SBT build definition[0] or Cargo.toml[1] to a typical VS solution[2] or project[3]. Which would you feel the most confident about when modifying by hand?

So why couldn't Microsoft include a tool for that migration? That seems like table stakes for such a migration project. We're not exactly talking about 2to3[4] or rustfix[5] here...

Amazing how Microsoft are completely unable to even get close to what the Wine and Mono people did years ago.

Throw a dart and you'll find something. If you want the out-of-the-box live-in-your-IDE experience then JetBrains' stuff is miles better than VS. Personally I moved on to Spacemacs[6] after a few years each of VS and IntelliJ.

-Probably placed at the upper end of the passband so you could use a single high-pass filter in front of the detector to get rid of any noise on the line, easing detection.

Also, if you wanted to remove the tones from the passband for some reason or other, you could do that with a single notch filter if the tones were sufficiently close.

That's surely not clear from the blog post. I just read it again and I still can't find it; indeed, the only links to apps are links to the existing Firefox Preview (not even to Firefox Nightly, which is what the article seems to be talking about).

Searching the store turns up both "Firefox Preview Nightly for Developers" and "Firefox Nightly for Developers" which is consistent with your claim but is not necessary supportive of it.

The title refers to an app apparently called "Firefox for Android Nightly" but no such app exists that I can find in the store.

It is possible this is one of the worst public announcements ever. A link to the product they're announcing to would have made a significant difference.

Hi,

Forums where stocks, crypto, etc. are being discussed are almost always filled with polarized opinions – with an overweight of extreme optimists at times harassing people with more nuanced views.

We have launched a public beta of Empiricast, a forum/game/learning platform where people's score is based on actual forecasting accuracy. We hope this will lead to:

- More informative and nuanced discussions

- People becoming more accurate and calibrated in their predictions over time

Would appreciate any thoughts you may have. E.g. what do you like/dislike, how can we make it more fun or useful :)
At flying speed, the wind may have even helped to dislodge and blow away the remnants of what didn't get wiped off.
Maybe you're pushing yourself too hard? Academia isn't all it's made out to be. If you know you're not going to enjoy it or be able to focus, maybe you're right to think about leaving.
It sounds like you have good experience, more and more software jobs don't require a CS degree. You're in a good position to work and be professional in your work - a degree doesn't make you professional. In fact, a lot of people with degrees find themselves in very different work roles completely unrelated to their study.
Maybe you need some time away from work or the place you live - to put things into perspective.
But please, don't hold academia in too high esteem and don't put too much pressure on yourself :)

The fact that pretty much all thoughts from people outside the field are either obvious, false, or nonsensical... doesn't invalidate the idea that flashes of insight can come from anywhere. I get what you're saying and agree the odds of it happening are pretty much zero. But sometimes even things with a probability of pretty much 0 can happen. The eigenvalue thing is an example of that, in my opinion.

I won't pretend to know anything in detail about climate science but these alleged discrepancies don't seem to have raised enough alarms at any point to have warranted a serious rebuttal from the scientific community. Perhaps citing a handful of random cherry-picked sources isn't really the smoking gun you think it is? However, fwiw, here's a comment from a couple of years ago responding to some of those points.

Also worth questioning whether the test was sufficiently far removed from the game itself that improved scores mean anything. Unfortunately the article is paywalled, but here's a quote from the abstract:

> Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2).

Probably it was a card sorting test. This sounds to me like "people who practiced card sorting got better at card sorting."
