That's the same study I was referring to, though. They didn't provide the impact of any individual control variable, just an aggregate of about eight different factors that are both social and biological. Also, they didn't show that their control corresponds to marshmallow wait time specifically, but instead that it's at least as good a predictor of academic outcomes. (Which means the control and wait time must be broadly correlated, but not necessarily that their 'errors' are aligned.)

What I'm hoping for is something that specifically breaks out the relationship of family income to "marshmallow score", even without a long-term followup. I certainly believe that they correlate, but I'd like to see how strongly, and how it varies across what range of incomes. Even among people who agree that wealth drives marshmallow patience, explanations range from "wealthier families can consistently fulfill long-term commitments" to "food insecurity makes kids take food now". An obvious way to differentiate those theories is to see whether a wealth/time correlation remains strong past the point of food insecurity. (Since the original study was limited to relatively wealthy families, I expect it does.)

I agree that behavioral economists wouldn't be surprised by this result, but I'm not sure they're sold on "it's just wealth", either. While news stories are calling this a failed replication, I'm seeing economists argue that this was a successful replication of the test's predictive power, and only indicts some specific casual theories proposed to explain it. In particular, several of the control variables in the replication are measures of child academic performance, so without an individual-factor breakdown, there's a risk that this is effectively controlling for the variable being tested. I think the "patience makes you successful in life" narratives are laughably wrong, but I wish we had some clearer data on what the actual correlations are.

Google could bundle a real ad blocker that used internal only apis.

That's the real dishonesty. Disabling the public API, claiming "because privacy", and ignoring the most popular use case for those apis.

Fwiw, Google isn't disabling any ability to use the apis to record, store, and forward, everything you do on the web. The only thing being disabled is canceling a request, based on live heuristics, before it happens. What privacy hole does that close?

Ubisoft Massive | Site Reliability Engineer (Infrastructure Engineer) | Malmo, SE | Onsite, Relocation/VISA offered | http://www.massive.se

My team is looking for an automation focused individual to help us release AAA games with the highest possible reliability, while supporting the needs of the adjacent programming squad. Our team is comprised of classically trained sysadmins who have always had a brush with automation, we work very closely with C++ programmers so experience or willingness to learn classic development styles are helpful.

Our stack is primarily comprised of Saltstack/Python/terraform running on google cloud and bare metal.
To give you an indication of an ideal candidate: they would have enough Python experience to be able to investigate and fix bugs with us (in projects like saltstack; and contribute them back upstream) and would enjoy doing so.

We make heavy use of Windows, Debian and FreeBSD, but knowledge in those things specifically is not paramount, typically we look for expertise in practical use of systems and infrastructure, concepts that go beyond the implementation of a single OS. A full Jobspec is here: https://www.massive.se/job/online-infrastructure-engineer-si...

We have _many_ other open positions for C++ programmers, Animators, Data Managers: https://www.massive.se/career/ each offers a relocation package and an additional VISA if required.
We move very quickly, have interesting challenges and enjoy a great work/life balance, despite our industry.

Lie detectors are woefully unreliable, but PDs use them.

Forensic “matching” of bullets to guns is basically pseudoscience, but continues to be used in court to convict people.

Roadside drug analysis kits are less useful than dowsing rods, but get people arrested on a daily basis. People that can’t afford bail, and plead guilty just to get back to their lives, despite the fact that an actual defense attorney would have had the case tossed in the trash.

Previous experience suggests that police tech does not just “get better.” They can’t even progress past “disproven pseudoscience.” And the innocent people that have their lives messed with while waiting for the tech to catch up might not be indifferent to the process.
I'm not convinced that Google can actually solve this problem by just reviewing apps more closely. It sounds like it took a lot of work for Jadali to identify a smoking gun, a lot more than Google could reasonably do preemptively or even as a response to every abuse report. And if Google had shut down three very popular accessibility apps with anything less than a smoking gun, I expect that would have been just as controversial as Manifest V3.

"Unlike web SSL servers there is no need to send a certificate back to the owner. LF is a global shared data store and therefore makes use of itself to publish certificates."

Nice! Thinking a bit about this - this sounds like it has real potential vis-a-vis traditional CA. With a (many) globally trusted db - it sounds quite feasible for eg Mozilla or Debian to simply store (or "bless"/trust) any number of root certs - and record that in lf.

And the same could be done for signing binaries (whether via x509 or some other scheme - "all" that is needed is some way to "discover" trust of the signing key after all - be that a gnupg key or a x509 cert etc).
It is a matter of personal responsibility. Just like obesity, smoking, and often type 2 diabetes.
There’s a lot of redundancy between class files in Java and zlib only has one feature for that and nobody uses it. It would require coordination that doesn’t really exist.

For transport, Sun built a dense archive format that can compress a whole tree of files at once. It normalizes the constant pool (a class file is nearly 50% constants).

Many Java applications run from the Jar file directly. You never decompress them. But you also only see something like 5:1 compression ratios.
a lot of people mentioning "thing," and it's simply not used that way. That said, "ting" of Jamaican Patois origin would be appropriate.
Unsure of it's intended or not, but the comment comes off really dismissive of what's been accomplished in the meantime. Studying Mars with "fancy RC car[s]" is vital for both visiting it and long-term study of the planet without unnecessarily risking lives. Our current technology also raises questions about mental health during such long trips.

The comment also glosses over the ~70 currently active missions on NASA's plate[0]. NASA also had some major success with good media coverage for other missions to Saturn[1], Jupiter[2][3], and Pluto/Kuiper Belt[4].

Please don't belittle the amazing work that has been accomplished by all the people involved over the decades just because it's not part of pop culture. They've accomplished those things despite having to walk the political tightrope and nearly anemic funding.

SEEKING WORK | Remote Part-time/Adhoc | Golang/Python/Java/devops

I'm seeking some adhoc/short-term Golang/python/devops (AWS/K8s) contracts over the summer while I work on other projects. Perhaps I can help with code reviews, architectural advice, as a sounding board, small scripts, etc. I've spent 4 years working as a big data engineer (ETL + analysis with Hadoop/Java, spark/scala, Google Cloud/AWS), another 4 years as a devop (AWS/Jenkins/Terraform) and several years as a full-stack web developer (python/django). I've most recently led a devops/SRE team building a K8s platform on AWS.

I'm the creator of sugarkube (https://github.com/sugarkube/sugarkube / https://sugarkube.io) - please see that for golang samples.

Please contact me on hn@sugarkube.io. I'm based in the UK but looking for fully remote work.
> Sacrificial PoW (as in LF, hashcash) only has value if reorgs happen.

That's assuming you need a reorg to adjust values. The original purpose of hashcash was anti-spam. That lends itself to allowing variable work factors and having the recipient's classifier regard higher work factors as a stronger not-spam signal, with the baseline set by the recipient administrator, or the mail daemon packager setting defaults for this year's distribution, as a trade off between false positives and false negatives.

Meanwhile a sender default of e.g. calculating hashes for ten seconds per message would cause the amount of calculation done to automatically rise over time as people buy faster hardware, but someone with slower hardware can reduce the false positive rate for their messages by increasing the time spent per message. Or someone with a high message volume but widely known and sterling sender reputation could reduce computation per message and rely on their good reputation instead, while less well known senders avoid spam classifications by doing more computation.

It works because it's all probabilistic anyway and having non-zero false positives or false negatives was already the status quo, so something that gets you closer to true is valuable even if it only solves 99% of the problem and not 100%.
Thanks Dustin :)

I was interested to see this other post show up on HN

At this early stage, I haven't started using any matrix factorization techniques since scaling isn't a huge issue when you only have two active users, but it'll be very relevant later on.

But is does have more and more easily used land. And while it looks very similar from outside Scandinavia it doesn't look quite so similar close up. Culturally similar but far from the same.

Topographically they are quite different, timber is more profitable in Sweden for instance because the country is much flatter and transport is much easier.

The two countries have different challenges to overcome and different histories that still affect the way people think.
