p-hacking is a research "dark pattern" where a researcher fits several similar models and reports only the one that has the significant p-value for the relationship of interest.

This strategy is possible because p-values are themselves stochastic and a researcher will find one significant p-value for every 20 models that they run (at least on average).

p-hacking could also refer to pushing a p-value close to the significant cut-off (usually 0.05) by modifying the statistical model slightly until the desired result is achieved. This process usually involves the inclusion of control variables that are not really related to the outcome but that will change the standard errors/p-values.

Another way to p-hack is to drop specific observations until the desired p-value is reached. This process usually involves removing participants from a sample for a seemingly legitimate reason until the desired p-value is achieved. Usually identifying and eliminating a few high leverage observations is enough to change the significance level of a point estimate.

Multiple strategies to address p-hacking have been proposed and discussed. One of the most popular ones is pre-registration of research designs and models. The idea here is that a researcher would publish their research design and models before conducting the experiment and they will report only the results from the pre-registered models. This process eliminates the "fishing expedition" nature of p-hacking.

Other strategies involve better research designs that are not sensitive to model respecification. These are usually experimental and quasi-experimental methods that leverage an external source of variation (external to both the researcher and the studied system, like random assignment to conditions) to isolate the relationship between two variables.
Are you saying, "no he didn't in theory" or "no he didn't in theory or in practice" ?
Related question: I am reading a book by an author whom I know socially. The book is very good, but I have noticed a few minor typos. I also noticed that one example is explained backwards — that is, it mixes up the causes and effects for two phenomena. I have not independently researched the phenomena, but based on the earlier description (which is logical and I believe to be correct), the conclusion of a section is clearly mistaken.

Is it appropriate or helpful to point out any of these issues? The book came out a couple years ago, and I imagine other people who know the author may have pointed them out already. I don't want to make him feel bad (no one likes the bearer of bad news), but if it were me I would want to be told so that future print runs and digital editions could be corrected. (The book is popular and will likely remain relevant for years or even decades.)

Perhaps I should shoot him an email from an anonymous email address?

Yep - thanks to services like these. Just telling people "not to burnout at work!" or "take time for yourself!" is shortsighted as it is not just work that causes burnout, but lots of people have responsibilities as well as their work life. You name it - single parents, carer responsibilities, multiple-jobs, etc these are not things that can just be opted-out of to get some "me time" to avoid burnout.

Where did I say "the world hasn't progressed since then"? That's a hallucinatory misreading & misrepresentation of my comment.

But also: those successes are attributable to mobile apps in general, not Apple's self-serving policies.

Plausibly, all of these should be possible as zero-install web apps – but as Apple (& others) have started raking in the App Store money, their investment in competitive open web technologies that could match proprietary-platform native-apps has languished.

Further, the App Store's market power is now being used to limit the functionality of such apps – banning competitive payment mechanisms, or entire classes of disfavored speech and content, or product benefits that compete with Apple offerings.

And the App Store plus iOS power is being used to torpedo the business models of Apple competitors – as with the changes in tracking defaults that have kneecapped Facebook revenues, mafia-style.

Flat Jobs and Thick Desires
I'm building a little platform to experiment with embodied / real-time multi-modal learning. Basically I have an old boom box that I gutted, stuck a USB power bank and a USB charger in there, along with a Raspberry Pi. The Pi will connect to one or more cameras, one or more microphones, and a handful of other sensors to let it sense its environment to various degrees. The main ones I want to work with are accelerometers so it can sense motion, temperature, and possibly GPS.

The form factor was intended to allow for portability (it has a handle and I can carry it around with ease, and the Pi can run off of the battery when then AC supply is disconnected) and to have enough space to allow for positioning multiple cameras for binocular vision and multiple microphones for stereo "hearing", as well as room for the other random sensors. Oh, and I'm re-using the existing speakers for the audio out so I can work on integrating speech synthesis into the whole kit and kaboodle.

For the software, I'm looking at starting with a super-simple BDI interpreter for the basic "cognitive loop", using an RDF triplestore for semantic knowledge, neural network models where appropriate (object recognition for example), and then start trying to build up from there. Also looking at systems like SOAR, ACT-R, OpenCog, etc. for inspiration.

Of course most of the "heavy lifting" from a computational viewpoint will need to happen on a server somewhere, since a single Raspberry Pi can only do so much. So there's a corresponding server backend piece that will work in conjunction with the remote portion. For now it'll be a fairly low-end server that's physically here at home, but if/when I start needing to scale things up I'll probably switch to using cloud resources on AWS as needed.

All in all, the basic idea is to have an "AI bot" that is alert, observing, and (hopefully) learning all the time and that will learn more like a child learns, compared to the way we train ML models today. That's not to say that there might not be some batch mode training as part of this but I'm hoping to experiment mainly with learning modalities than can happen in real-time. There's no fully fleshed out theory that I'm working off of, but I plan to tinker with a variety of things - Hebbian Learning, Reinforcement Learning, etc. Maybe I'll learn something interesting, maybe not. But it should be fun in either case.
Lightning network on bitcoin has fees that are a few cents at most, is this still a problem?
Yeah I understand that. I was trying to put it nicely as talking about US immigration and border patrol policies make me very sad to be from the US.

It’s a complex issue but at the end of the day current policies end with people not being treated like humans.

My wife is from another country and the mental tax that going through the US immigration system has had on us took two years to recover from. The entire system is meant to be punitive and humiliating.

It doesn't "follow" anybody.

The uniswap "algorithm" has no other choice but to follow the "market". Otherwise, it would do no trades.

Binance's trading volume is 40-50 times that of uniswap. What Binance does affects the price on uniswap --- way more than the other way around.

If Binance mints USDT and uses it to buy lots of BTC, what happens to the price of BTC on uniswap? Once the price on uniswap and other exchanges starts going up, others see it and jump in to avoid getting left behind --- driving it even higher. What happens when Binance then sells BTC?

This is a classic "pump and dump". It happens all the time because there is nothing to stop it. Binance is the one controlling "the market". Uniswap with their "algorithm " just plays along.
You can certainly fine them until they do, which is generally how this works.

It basically is how you say it should be, with the pre-sorting distributed to the leaves of the tree (banks and funds).

When a client approaches you, broadly, you have to sort them into low risk, medium risk and high risk.

Low risk you waive through.

Medium risk you do some digging on but if you’re then happy, you continue.

High risk, you alert the authorities. Then they take care of this. You put the client on hold. The authorities may later give you a formal go-ahead. At least this is how AML works in Europe, I’m less familiar with US.

So if the institution is concerned enough to refuse services, they absolutely must alert financial supervisors too, and it’s up to them how to proceed. They give you the go-ahead or the red light.

Strictly speaking you could still refuse a client then, eg if you think they could be on a sanction list soon enough, but that’s business reasons, not supervisory.
Semantics aside - the Act does allow for the suspension of civil liberties that should be troubling to everyone. The ability for a government to unilaterally lock people out of their bank accounts without a court order or any form of recourse is virtually unprecedented in Western society. Likewise, retroactively labelling a behaviour as a crime, then punishing individuals for it is explicitly against the Canadian Charter of Rights and Freedoms. Being 2022, most financial transactions are electronic. Locking people out of their bank accounts is severely restricting their ability to buy essential goods such as food, shelter, transportation, etc.

Remember, it's not about the individuals, it's about the precedent it sets. If the government can do it to those you disagree with, they can (and will) do it to you.
I wanted ECC, got a 2015 Xeon 4c/8 Thread E3-1230 v5 (cheaper than the i7 of the time), 32gb ECC ram, gtx1070, and a SSD. It's been reliable and fast. I think I paid $1,500 for it (not including 2 27" 2560x1440 monitors). I do admit to upgrading from a small SATA SSD to a larger M.2 NVMe SSD which did seem to make boost some things nicely. Especially working with large directories of audio, video, photos.

Had a few friends buy $2k-$3k laptops around then, all of which have been replaced years ago.

Building software (unless it's a big Rust project) is quick enough to not care. Occasional gaming (random steam games, warzone 2100, even valheim) seems fine full screen. Even watching 4k downscaled to 2560x1440 seems fine.

Sure 7 years later I'm considering an upgrade, but not sure I'm going to notice. A zillion terminals and chrome tabs don't seem to slow it down at all. Looking for PCIe-5, DDR5 (twice as many channels), and a mid range Alder lake, or the coming out later this year zen 4. I would like ECC so I'm leaning towards an alder lake flavored Xeon (when they come out), or a Zen 4 desktop or laptop. Or maybe a SFF (typically laptop parts in a small desktop case with a integrated GPU). The new "zen3+ and RDNA2" chips sound like plenty for the next 8 years.
It would be more admirable if Atlassian weren't a $5B company with a history of paying zero tax.

I consider this at best a decent attempt at making amends (assuming tax dollars go towards the greater good, which they largely do in Australia), and at worst just virtue signalling for something which was never going to happen in the first place.
For sure, it's a balance, which is why back to work legislation is used sparingly. It also has been given a very high bar by recent Supreme Court rulings.
I’m typing this on an iPhone 8+ because I’m unwilling to move to faceid only. So I admit I’m coming from a position of ignorance, having never relied on faceid day to day. Part of my reluctance is that I want to authenticate when I choose to. FaceID feels like I can’t do that. Hold my device in front of my face and it will unlock whether I want it to or not. I’m already staring at the phone when an app asks to authenticate. I like the fact that I have to deliberately move my thumb to the reader to authenticate.

I have had to unlock my phone while driving so my partner can get something. Her finger isn’t authorised. :) I can touch my phone and unlock it without looking away from the road. FaceID seems badly suited for the car, unless you just have your phone unlocked all the time or CarPlay.
Can you expand on the gates (using many more of them) that work off the fpv video signal? You can add cameras detecting motion and not worry about which drone is which (getting that from fpv signal as it passes the gate).

Then interpolate with accelerometer data from the drones telemetry?

Dunno seems hard anywhich way but having more than one tech involved to cross check seems like it might help.
That's how I've personally felt since I first encountered ORMs a decade ago at a data intensive startup where ORMs were a burden. Yet I keep running into ORMs.

Luckily, they are better implemented at my current job. I still think it gets in the way quite often, but I recognize that it enables some outsized returns on effort. Entire REST APIs can be generated with things like Spring Data. SqlAlchemy can be pretty slick in Python.

I still write raw SQL on my personal projects, but I recognize that I have to spend a lot of time doing that.
Boring Company seems clearly focused on hyperloops as the long-term goal.

They determined that construction of tunnels would be orders of magnitude faster on approvals than above-ground construction.

With that approach, tunneling construction is the key technological block. With SpaceX and Tesla's know-how, the actual construction of a hyperloop is rather de-risked.

By keeping laser-focused on tunneling tech, they build the muscle around the regulatory process, get cities and states to trust them, and show operational competence in operations.

Once they do a intra-state system in a friendly regulatory environment (FL/TX, ala Austin -> San Antonio or Tampa -> Orlando), they'll built a corporate machine that's tunneling dozens of underground highways across the country.

At that point, building new tunnels as a hyperloop will be a reasonable mid-term goal.

A student would be optimally correct in trusting authority as far as believing the axioms of the electromagnetic theory goes.

This comment reminds me of Carl Schmitt's observation that nothing in a Liberal Democracy prevents it from becoming totalitarian (or otherwise.)

His books are more relevant today, as the state is re-establishing its authority to define "friend" and "enemy". "Good" and "evil".

Tolerating the "other" side's views is no longer acceptable.

The state is re-establishing its authority (and monopoly?) to determine public "friend" and "enemy".

In 2011 I gave a talk in Germany at the Chaos Communications Camp entitled "Financing the Revolution" which makes the argument that uncensorable payment systems are an essential prerequisite for a free society, as without them, you cannot exercise basic rights:

https://media.ccc.de/v/cccamp11-4591-financing_the_revolutio...

I cited the banking blockade by Visa, Mastercard, and PayPal used against Wikileaks/Assange as evidence that, at the very least, publishers need to be able to send and receive payments that the state does not wish them to be able to send or receive.

Last week, I wrote about how we as a society need to be prepared specifically for user-friendly, widespread unstoppable payments, as the technology now exists for actually private, uncensorable payments to reach a wide audience.

Most new products are positioned to grow into a form of locked-in market that you can extract value from, drawing a box around their customers for the sole purpose of squeezing it in the future. This business strategy is a mind virus and has even overtaken the aspirations of bright-eyed entrepreneurs. The aim has fallen from the simple "get rich by selling a $1 item to 10 million people" down to "create a product where customers are trapped in a dependency relationship with the product by design, give it away below cost to push out alternatives, then flip it and squeeze them for as much as possible" (where the last part is omitted from the initial business plan but still implied, and enabled by outsourcing the dirty work to new management via buyout).

The primary goal should be to maximize value, and within that a balanced tension between maximizing delivered value vs maximizing captured value. It's reasonable to be compensated for the value you add, but it needs to be in service of maximizing value in general. If the correct hierarchy of goals is inverted and capturing value becomes the primary aim then it inevitably devolves into this antisocial, monopolistic, lock-in behavior.

Canadians have a right to protest. Canadians also have a right to the enjoyment of their property. The former does not override the latter, and the latter was severely infringed upon by the occupiers.

These protests caused hundreds of millions of dollars worth of damage. There is a $300M lawsuit against the occupiers in Ottawa, similar ones will happen against the occupiers of the Ambassador bridge.

The bank accounts have been frozen via two different mechanisms -- by the use of the Emergency Measures Act, and by a preliminary ruling in the civil court.

The freezing via the EMA would thaw after the EMA expires in a few days. The freezing by the civil court will not, and will likely result in the loss of those bank accounts.
The parent commenter brought up “drag on human progress and welfare” and keeping the topic to Tech companies I was pointing out there are far worse.

There are studies that show social media causing mental health issues and issues with spreading misinformation, many have shown up here on HN. I was stating my opinion which should be obvious, but maybe it’s not, every comment where you type into a comment text box is an opinion. I don’t have a grudge, just think the contributions to humanity by social media companies are far less than the problems they cause.

The hypocrisy on HN is funny sometimes, many times articles/comments about startups are about monetizing and charging customers more, raising capital, etc. and then for large companies they charge too much and it’s a “drag on human progress and welfare”?
