> Prosperity theology (sometimes referred to as the prosperity gospel, the health and wealth gospel, the gospel of success, or seed faith)[A] is a religious belief among some Protestant Christians that financial blessing and physical well-being are always the will of God for them, and that faith, positive speech, and donations to religious causes will increase one's material wealth.[1]

If you take a matrix of covariance or similarity between neurons based on firing pattern, and try to reduce it to the sum of a weighted set of vectors, the number of vectors you would need to accurately model the system gives you the dimensionality of the space.
The constant derision of journalists in tech circles (especially on HN) is kind of shocking to see. Did you read the article or did you miss that the journalist is relaying fellow researchers' apprehensiveness about Facebook being allowed to conduct an unethical study. This article [1] is linked in the second paragraph.

4000 exists, but there are only mobile chips in that line.
I liked the last line: ‘In California, the "daughter from California" is known as the "daughter from New York".’
Matter of taste I guess. I always disliked the linux way and prefer clear separation of concerns.
It's a good question. It looks like they actually specifically check for this and show that it's not two separate groups of neurons. Instead a subset of the neural population changes their representation of the input as it moves from sensory to memory, so it's more like a single group of neurons that represents current sensory and past memory information in two orthogonal directions.
deep neural nets are an extension of sparse autoencoders which perform nonlinear principal component analysis [0,1]

There is evidence for sparse coding and PCA-like mechanisms in the brain, e.g. in visual and olfactory cortex [2,3,4,5]

There is no evidence though for backprop or similar global error-correction as in DNN, instead biologically plausible mechanisms might operate via local updates as in [6,7] or similar to locality-sensitive hashing [8]

If you dislike a _b_ version of an a/b tested site to the point that you feel deeply dissappinted by it, were the people who designed the experiment operating with a malicious intent?

I don't think facebook engineers or data scientists care what people feel when they're adjusting their models, they only care about time spent on their platform or some other overly reductionist metric. One could argue that chasing super-efficiency will always result in abominations, but I think its hard to say that someone is doing something imoral by just doing the human equivalent of gradient descent in the optimization problem of driving engagement. That's not to say that we shouldn't have a conversation about this and not figure out ways to make these super efficient and powerful companies find ways to be satisfied with organic engagement.
I tried using nix on a Mac, because I really respect what they're trying to do and it seems like a "right thing" kind of platform which I want to support.

I wasn't able to get it to work, and it left a bunch of users (like ten??) and other various junk which was a pain to clean up. This was in 2017 I think.

I keep hoping someone will chime in and say "I use nix on my Mac, and it's dreamy, everything Just Works you should try it!" because until that happens I'm going to stick with brew.

While I'm on the subject, I was also a macports user until hmm, 2013 I think. Don't recall exactly why I switched, just that I was having some kind of intractable problem, messaged a friend who knows what he's talking about, and he said "just use brew dude". So I did.
Thanks!! Appreciate it
Odd to see this casual sexism thrown in at the end of a technical article. Imagine if I just randomly threw in how long women take to get ready or something at the end of a technical article. It would be completely bizarre and my sanity would probably be called into question.
In related news, to keep their job or occupy their time, journalists and social media commenters continue pretending that web users have self-respect.

For those of you wanting an explanation of what I meant here, this is a perfect example of it. I do actually have aerc installed now. I just think it's annoying that I had to change my perfectly good workflow that is enough to get me hired at large companies for this.

And I guess almost all of those Windows servers in the back offices of small businesses running Active Directory and Exchange are now also gone.
Oh how I wish I could do this on macOS. Yes there is a "reduce motion" setting but there is no remove motion setting and a whole bunch of animations remain most notably minimize/maximize of windows (I can at least change from the default Genie effect to Scale which is faster), opening an application it still "zooms" into the screen, etc.

I would happily pay for a third party app to nuke every single damn animation if I could but Apple make it impossible (or at least that is what is claimed).

And of course this doesn't even touch on how laggy resizing many applications on macOS is (yes even on the shiny new M1 models). The Microsoft Office suite, Chrome and a whole bunch of other applications are horrible when resizing. It isn't often an issue with Apple's applications for what that's worth.
Why did you make this comment? Is it what you believe happened?
Thanks for taking time to check and comment. It will be nice if you can provide suggestions that can help in making the platform which you think will make it reach and/or go beyond your level of expectations.
Same boat here. Wife deleted her account. I keep mine only to use the market (currently, the best place to sell bicycle parts locally). I'll probably delete my account once I do my next round of parts bin purging.
I'm skeptical of the author's premise because there were plenty of barbarian tribes outside Rome's borders, who made almost no progress in their civilization for the thousand years that Rome stood. If Europe had fallen entirely to them, why should anything have changed? Even the simple (re)invention of writing may have not come for another thousand years (by which point all of Europe would have been conquered by Arabs anyway). The point is: the iron age is slow.

Rather it all seems to depend on the crucial fact that the barbarians immediately adopted the culture, religion, and especially the (highly written) language of the Romans. Which is highly peculiar: not often in history do the conquerors adopt the customs of conquered. But without this transformation, I don't believe Europe in the West would have become anything but tribes of illiterate savages, like it was in the North.

So if the fall of Rome was for Europe's benefit in the long run--and it may have been--then it's because we got very very lucky. In the meantime, don't be too hasty to throw away today's great civilizations. I do not think it is usually so easy to revive them.

P.S. The author's insistence on pausing every few sentences to needlessly scourge "colonialism" and "slavery" and "white supremacy" and other assorted buzzwords is very irritating.
I think this might have changed a bit over the years. I can’t remember last time I had to tinker to build a port. But you’re right, it wasn’t uncommon around 2010.
Instead of BFL, I only buy products that I'm ok with getting destroyed or products I have a laid out upgrade plan for. Example: All of my pants are Levi's 501s. I can get them for 50-60 bucks, which is nothing. They last a really long time, but they're not made in America nor do they have a lifetime warranty. BUT I don't have to worry about spilling stuff on my pants or going through the tedious process of filing warranty claims every time a button breaks. I just get on the app and order a new pair.

What's more important to me is narrowing down the list of brands I buy from so I spend less time thinking about shopping and more time being productive.
A SDR + some sort of "stream deck" from the parent article could be a potential "offline" solution. You could even wire a couple mechanical keyboard switches to Rpi's GPIO pins for selecting preset channels and avoid the stream-thingy all together.

Surely, people understand that Facebook makes changes to their website, and that these changes are based on data. That is all an experiment is. If Facebook wasn't allowed to experiment, they would never be allowed to change their interface or recommendation engine at all.

Agreed!!! I mean, there have to be limits, right? :)
I don't understand how there is no sensor to shut off the motor when it detects a jam. That's like basic safety protocol there.
Exploring the New Features of CUDA 11.3
ZSDOS provides replacements for two of the three parts of a CP/M system: BDOS and CPR. The existing BIOS should work perfectly with these replacements, and the BIOS is the only part that is machine specific.

IOW it should run just fine, unless the simulator is written to hook into CP/M itself. I have my own z80 based system emulator where the BIOS is basically breakpoints into host code, and I didn't need to change anything to switch from DR's OS to ZSDOS.
> that address the firestorm of hate that anonymity has brought down upon us

I disagree with many (most?) of your underlying assumptions about social dynamics, but this one in particular stood out to me. Have you not seen the vile things that people post to Facebook under their legal name, typically to groups consisting almost entirely of people from the local community?

It isn't anonymity that's the problem. It's the intent behind and incentives provided by the social interaction in question. There are deep systemic issues (IMO) with the interaction models of most social media today.
Yes but only in aggregate, like how adding a column to a database table is also adding a "dimension" to said data.

I'm not convinced the author's analogy of cross-writing to fit more information on a page is actually going to be helpful to most people's understanding. It led me at least to try to imagine visually what's going on, to picture the input being physically rotated. This is more akin to the more abstract but inclusive concept of rotation from linear algebra, where more dimensions (of information, not space or time) makes sense.
> Substitute the girl using the treadmill with one of the parents. The kid with the ball still gets caught, although the treadmill could get stopped sooner.

Doesn’t seem likely. His parent would either fall because the treadmill slowed down, running into him and injuring them both or they would have told them to stop it because it’s clearly dangerous
My impression is that even reasonably well-selling non-fiction books typically do not sell a lot of copies. To make it onto a best-seller list you only need to sell in the tens of thousands of books.
Edit to add: Sorry, I should have commented on the original article. I like this article and think it presents a good basis for the early part of the process for many people... I wrote the comment below because my book largely picks up after the point covered here.

I'm in the midst (about 18k words in) of writing a book about publishing specifically for technical people. I do talk about traditional publishing and self-publishing, with most of the words focused on actionable advice to avoid common pitfalls when self-publishing.

I've been previewing some of the information (not in the form in the book, but just some of the topics) on my newsletter:

woodworking projects. I have never said anything about woodworking or joined any wordworking groups on facebook. They are just making a guess that someone like me would find those interesting.
It's nothing personal against journalists, but the economics of the business mean that they have huge incentives to make things seem more outrageous or nefarious than they actually are.

I did read the whole article, and that doesn't excuse the BS clickbait title of "Facebook deliberately made people sad."

I find the fact that the article is complaining about emotional manipulation by Facebook, while using a deliberately manipulative title, to be more than a tad ironic.
In that case they will never guess: "If your fetish is geriatric alzheimers, then you are 120% right"
So memory and sensory get multiplexed?
Wait.. why is it significant that vscode has the sandbox disabled? Isn't executing (curated) arbitrary code part of its core functionality as an IDE? I am thinking extensions and ability to define tasks including arbitrary commands and so on.
You are correct about the dictionary definition of the word, but in popular parlance the phrase "conspiracy theory" has a massive negative connotation. I have literally never in my life seen someone use the phrase without intending to imply "crazy/unprovable/etc".

Yea, would love a ThinkPad with amd and 32gb of memory (looks like they now can go to 32gb, but think they were all soldered 16gb last time I checked). Not quite as pretty as a Mac, but probably they best laptop keyboard I've used.
Doesn’t that suggest professional ethics are immoral? They block a temporary, one off experiment which could suggest how to avoid sadness.

The alternative is relying on intuition only and possibly making people permanently sadder. Or is there a way to achieve this knowledge consistent with the field of research ethics?

We saw this with challenge trials in the pandemic where ethicists fretted people would reject them and concluded challenge trials are immoral. Meanwhile opinion polls suggest people view challenge trials as virtuous and the current method of waiting for infections as immoral.
Guess why you need to opt in to a drug trial.
This makes much more sense than having secret memory cells in neurons.
> but I've never read a book that "solved my problem". Of which, I assure you, I have many.

Curious of your unsolved problems.
Same. Especially sharing any binaries between applications. For a single user desktop system it just seems like a backwards idea.
I checked my treadmill and it doesn't as well. I also googled trying to see what they look like. They seem to be used on treadmills that sit higher off the ground.

My guess is that the Peloton design is more dangerous due to the treads, the thickness overall and how to high it sits off the ground. Perfect design for sucking things under.
I agree with you. It looks like it made it onto the site because it has a lifetime warranty. Still, I’m not keen on eating flakes of PFAS aka Teflon as these types of products wear out

How would it have been ethical?

If their current process was already suspected to be the worse of the two, and their goal was to improve peoples' moods per se, what is the ethical thing to do? Keep people feeling more sad?

Or, perhaps, stop being algorithmic in what people see, or else put people in full control of simple sorting (prioritize my "starred" category and sort by date)?

I think there's a business opportunity around people who aren't tech literate and want what tech they have to stay the same, but every time I think about what an ecosystem that could handle everything from photo sharing to email to even the TV, it seems like a fool's errand because the market seems small, it keeps shifting to people to are comfortable with somewhat newer things, and I don't think enough people would actually pay for it.
I collected coins avidly when I was ~10-13 and the hobby just re-ignited itself with me again, now 30 years later (I can't exactly explain how or why, but here we are).

I went to a coin show today on a whim and what I discovered was that there are ALL types of collectors, and everyone should really understand that:

* There's 10 year old me that was obsessed with finding the rare die varieties hidden in the $1 bins,

* There's 42 year old me that is now getting deep joy buying the rare gems (1790s silver dollars, $20 gold pieces, etc.) that were beyond out-of-reach of 10-year-old me

* There's folks who obsess over filling every date of a specific series

Etc. etc. etc.

Find your joy and run with it, and definitely don't try to tell someone that their joy is the wrong one.
In a couple of lectures on translation, Hilaire Belloc acknowledged the use of the historic present in French, but cautioned against it in English. I think that the historic present is fine in fiction. However, it sets my teeth on edge in history--though the only time I've ever encountered it was in Bill O'Reilly's Killing the Rising Sun. (It was a neighbor's pick for the local book club.)
One really nice thing about safety-critical activities is that the equipment tends to be made to extremely high standards and usually lasts a very long time.

If you buy equipment for climbing, shooting, scuba diving, etc. you can reasonably expect that it's made to a very exacting standard (almost certainly in the US, Japan, or Europe) and will last many years (with well-defined consumable components and maintenance requirements).
Think of it less as n-dimensional in meat space and more of n-dimensional in how it functions.

Also, “managing out” is one way of coddling a team but it’s not a choice. At best it convinces team members these people quit, but that’s hardly the reality of what’s going on.

The commentary is more on the clickbait title, which very likely could have been written by someone other than the article’s author. (NB: journalists do A/B testing to pick the title that incites the most clicks from outrage[1].)

Further, the article you link appears to have commentary by a single researcher.

Here’s a writeup by researcher who thinks it wasn’t unethical at all and that it would have passed IRB as performed. It, of course, does not end the discussion, but it does demonstrate that the issue is more complex than a company deliberately making people sad:

He is a worldwide treasure.

For all the negativity that modern internet has brought, we forget that a poor Indian kid with a cheap smartphone can watch Stanford lectures on astrophysics. Just think how crazy this was even 20 or 30 years ago! Anyone with an internet connection has access to more books than she could ever read in a lifetime, lectures and videos from the best learning institutions and the best teachers in the world (such as 3b1b), they can ask questions to knowledgeable people and fellow students... Magical, for millenia this was inconceivable.
You should see how much made in America Levi's cost.
I like this definition too; the advantage is it scales with advances in technology. What has medium a decade ago, might be considered small (ish) now.
Sounds like cope to me ;) don't worry, the insitutionals will jump right in to prop it up.
I just found this out the hard way. After playing acoustic for ~15 years, I decided my birthday this year was the time to join the world of electric guitars. I joined several guitar related FB groups, expecting them to be as civil as the tabletop gaming groups I belong to (my other hobby). I quickly found out how wrong I was, it seemed there was no topic too mundane to turn into a mud slinging gate keeper competition. Not sure what it is about musical instruments that makes it that way.
This really would have been harder for me to understand had I not taken linear and abstract algebra courses a few years ago. That area of maths reused common words like "rotation" but with more generalized definitions, which made it was jarring and confusing to hear and take in at the time. When someone said the word "rotate" my mind as if by reflex was already trying visualize a 3d or 2d rotation even when it made no sense for the problem at hand. Being an English speaker my whole life I thought I understood what a rotation was or could be but I didn't.

Same goes for what's being alleged here: Is there even a way to visualize this that makes mathematical sense?
What will be the corollaries to this discovery simply as a result of what the mathematics of rotations will dictate?
Cocaine, MDMA and LSD seem to be favourite drugs around town, here in BC. I mean, besides the usual marijuana, tobacco and beer.

I probably lean more towards your side of things (or even just outright agree with you), though I can see how RMS's position isn't inherently inconsistent.

There's a difference between the legal construct of copyright and the technical enforcement measures foisted on buyers or computing hardware. Wanting to rely on the legal construct while avoiding the later strikes me as excessively idealistic... but we're talking about RMS here.

It's not exactly analogous, but it seems somewhat similar to supporting enforceable stop signs and being against using a camera to do so.
Value of Time
Do you mean due to the thickness of each connection, they would occupy too much space if the number of dimensions was too high? Not necessarily 4 or more, just very high because there are on the order of n^2 connections for n neurons?

In the visual cortex, neurons are arranged in layers of 2D sheets, so that perhaps gives an extra dimension to fit connections between layers.
