> If psychology could make predictions to the 13th decimal place like we are able to do for the gyromagnetic ratio of the electron (and confirm via experiment), there would be no complaints.

That's not a fair comparison. Medicine struggles to make vaccines that are more than 95% effective. HIV tests are 99.97% accurate. The mind is even squishier, psychology will always look amateurish compared to physics.
> the number of "true believers" I'm seeing here is astounding to me.

Because maybe when you see crypto, you see scams (SBF, Terra, etc). When we see crypto, we see legit decentralized asset like Bitcoin or massively successful open source project like Ethereum.

> After a decade of use the tech hasn't found many real world uses

Or maybe, there are legit uses but you are ignorant because of your bubble? I compiled some examples here long time back: https://news.ycombinator.com/item?id=32406095 (and this has only grown since)

> money laundering, tax evasion, and other financial criminality

That just depends on your pov ("freedom fighter vs terrorist"). If someone is trying to protect their wealth from Venezuela, Putin, Taliban or other despotic regimes, that is still "money laundering" in those regimes' eyes. See my examples above.

> I have no trouble sending fiat money where I need to at the click of a button

My colleague begs to disagree. He can send fiat USD to his native country but official exchange rate is suppressed and he loses a lot of value through fiat channels.

> I don't understand how intelligent people can continue to believe this stuff is the future of finance.

I don't think this will supplant finance as much as augment it. Also, maybe you haven't yet had real conversations with intelligent people who believe in crypto?

> it's something something human nature

Yup. Wanting to escape oppressive regimes with your wealth. Or freedom to protest your government's tyranny (imagine the uproar if Trump had frozen assets of all the BLM protestors in the summer of 2020. Now see what happened when Canadian goverment froze the assets of truckers).
If I have an iPhone, Mac, Windows PC, and Android Tablet I want to know and talk about what I can do with Passkeys, not what could theoretically be done. After all, I'm not looking at Passkeys for an academic exercise. I'm actually looking to see how feasible it is for me to use Passkeys to replace my passwords today.

If that means "install BitWarden on all of your devices. The devices will work with it and you can backup/export your key locally" that's fantastic, I'd love to see a guide on how to get that going on all of my devices. However, if that means "according to the standards, something like a BitWarden could do what you want it to do, if they built it, allowed export, and the devices all allowed integration. Alternatively, you replace your devices with ones that do." then I really don't care what the theory says could be done, Passkeys cannot actually replace my use of passwords at the moment.
There's a ton of ongoing research on this and I don't think it's reasonable to ask for a summary in the comments.
This Jacob Wohl guy is a real class act. He's certainly nothing short of an aspiring propagandist.

I was thinking it was more of a Zuckerberg strategy. At various points in Facebook's early history, users would voice protest about new features, such as news feed. They pretty much ignored the feedback and let it keep growing beyond the size of the critics.

Reddit probably doesn't have as much growth as fb did of course.

Following the OP's assertion, they could have been even more successful if they weren't remote. Neither of these assertions (a general case assertion) nor a cherry picked set of anecdotes, proves the ideas.

Everyone is arguing about the age-old questions around productivity and how to measure it, in software development. Google's tracked metrics fell (probably after a time of instability or increase) and so the organization is reacting.

>I am a little surprised how much anti-Psychology sentiment there is on HN.

When you consider the extent it is trusted to produce truth and the extent that such 'truth' influences public policy and law, I think encouraging distrust of psychology is a social good. There is a difference between talking the details with the experts who recognize the limits of existing studies and talking about 'Psychology says we should do X' with the general population who aren't aware of the concept of reproducibility.

It is much like discussing the possible uses of crypto. If another friend in tech is talking about some possible benefit of crypto, I take a completely different approach than if my gram calls me up asking if I heard about new crypto tech X that will double her retirement.
That's pretty cool. It's still possible it was persuaded for the wrong reason but in my experiments I've also found it's more capable of reasoning than most people give it credit for.

In my experience, giving code preferential treatment is how you end up with complexity lunacy; so I’ll add an addendum to Conway’s Law:

“Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization's communication structure — and which mirrors the skills of its key creators.”

K8s is designed to solve Google problems. Your startup will not have Google problems. Your startup will have Pinterest problems, or Gitlab problems, or Reddit problems — at which point you do not need K8s; you need someone who knows infra (which I expect devs to be working on distributed systems to understand).

Using K8s in a startup context is a sign of conformist thinking, detached from any critical aspect.

Most (all?) german train stations don't have barriers. So even though the ticket has a barcode on, there is a good chance that many journeys that barcode will never be scanned by anyone and there will be no central record you ever got on that train.
"Digital-only" = By smartphone app OR by smartcard, i.e. a card like a credit card with a chip and your personal unique ID stored on that.

In other words: You cannot get a plain old paper ticket without personal information, the ticket is like a cookie which identifies you as a user and thus allows you to be tracked.

While I'm also unhappy it's not being offered as a physical ticket, I can say from roughly 10 trips between 200 and 500km and a lot of local metro/bus riding that the frequency with which your ticket is actually checked shouldn't be enough to provide enough data for sophisticated tracking (esp. in comparison to "the normal amount" of GPS/tracking/movement data that smartphones already produce throughout the various apps we all have installed and that are being used on during trainrides)
Not understanding how many letters are in a word or exactly which letters are in a word reminds me strongly of the experience that I had when I tried to play hangman with chatGPT back around Christmas time
I think it's incredibly accurate. Humans can misinterpret some internal inputs as external inputs and we hallucinate. This is doing the same, erroneous interpretation leading to nonsense interactions.
I find it really wild that anyone would ever recommend ECS. A developer deploying a service involves:

- Setting up certs (managed as TF)
- Setting up ALBs (managed as TF)
- Setting up the actual service definition (often done as a JSON, that is passed into TF)

Possibly other things I'm forgetting.

Some other things. It requires a *developer* to know about certs and ALBs and whatever else.

With EKS, this can all be automated. The devops engineer can set it up so that deploying a service automatically sets up certs, LBs etc. Why are we removing such good abstractions for a proprietary system that is *supposed* to be less management overheads, when in reality, it causes devs to do so much more, and understand so much more?
> It’s also the first map made from a bird’s-eye view, which suggests a kind of sophisticated and abstract symbolic thinking that typifies modern humans.

Aren't modern humans largely unchanged for the past XY,000 years?

Wouldn't it be more accurate to say that this is the kind of sophisticated and abstract symbolic thinking that typifies modern human cultures?

People aren't going to think (as much) in abstract symbolic ways, if their culture doesn't.

Phasing out PFAS over a 5-10 year period or imposing a steady-increasing tax on its usage (to the point that eventually it became an apocalyptically high tax) would drive supply chains to adapt and move to alternatives.

My services usually produce around 2GB of log data per day. From quick read on the CH I beleive it should not be a problem. Not sure how big the database it is but zip compressed log data is around that size for entire month.
Thanks for the feedback. We know we're tackling a big problem here. Our ultimate goal is that if you use Infield we keep you on the latest version of every dependency, automatically. The road to get there can go a number of ways.

> My biggest pain isn't with the plan. It's with the actual upgrade process. Things _always_ break. Every single time we do a major upgrade, there's this long tail of things we need to fix. Even worse is the undocumented changes that break. This gives me nightmares.

Planning is one way to make those major upgrades go wrong less often. Our idea is that we can break large upgrades down into incremental changes that are individually safe and mixed in to your regular dev cycles, so that when you go to do the large upgrade you're not making such a big change all at once. This means things like fixing every deprecation ahead of time and making sure all the other dependencies you use are compatible with the version you're upgrading to.

We're calling this "upgrade paths" in our tool. Something like a major rails version upgrade is terrifying because of all the moving parts. Often you may have a dozen other gems that need to be upgraded in order to upgrade Rails. You said "If I can incrementally upgrade one package on every PR until I'm up to date, that'd be amazing.". We want to make that the flow for major framework upgrades, so you're merging in incremental improvements in the blocking dependencies ahead of time.

Undocumented breakages are for sure on our roadmap. We have two types in mind today:
- Changes that are missing from the changelog
- Incompatibilities across gems (for instance there was a time recently where if you had both datadog and newrelic installed and used elsaticsearch upgrading the newrelic gem would break prod)

We have some ideas on how to figure this out automatically (like reading code diffs with GPT rather than just changelogs), but the best way is to see upgrades out in the wild. As we see more and more upgrade experiences from our customers we'll be able to catch these issues and build this dataset.

I'd love to hear other ideas for making major framework upgrades safer.

> * It ran the repo's test suite against progressively newer versions of dependencies. Showing when and where unit tests fail.

Would this be something like `git bisect` for upgrades? We run your CI to figure out where you can upgrade to without something breaking? We're trying to figure this out statically by reading changelogs and building up a database of breaking changes. Our roadmap is to make this database better over time by pulling in more and more undocumented changes (by seeing customer upgrade experiences and by sourcing information from places like github issues). In my experience it's more common (and much more dangerous) that things break when your dependency changes in a way that wouldn't be caught by CI.
I asked Claude[1]: "in linear algebra, is the following true? (A) = C(AA^T)"

and it answered:

Yes, that is correct for appropriate matrix sizes. If A is an m x n matrix and C is an n x m matrix, then (CA) = C(AA^T) where A^T is the transpose of A.

This comes from the property that for any matrices A, B and C of appropriate sizes:

(CA)B = C(AB)

Applying that to your example, with B = A^T, we have:

(CA)(A^T) = C(A(A^T)^T)
= C(AA^T)

So in short, yes your statement (A) = C(AA^T) is true for matrices A and C of the appropriate dimensions.

Then I asked it: "in linear algebra, is the following true? C(A) = C((A^T)A)"

and it answered:

Yes, that is also true for appropriate matrix sizes. This follows from a similar argument as before.

If A is an n x m matrix and C is an m x n matrix, then:

C(A) = C(A^T(A^T)^T)
= C((A^T)A)

So the statement C(A) = C((A^T)A) is true for matrices A and C of the appropriate dimensions.

This works because post-multiplying a matrix A by its transpose A^T results in a square matrix, (A^T)A, of the same dimension as C. So C can be multiplied with that resulting square matrix.

In summary, both of the statements you provided are true linear algebra identities for appropriately sized matrices:

(A) = C(AA^T)
C(A) = C((A^T)A)

Hope this explanation helps! Let me know if you have any other questions.

I have two male cats, brothers, of which one becomes very needy and whiny after I'm gone for a few days (hes a needy little guy). He stays close, follows me around, whines and mews for attention, and sleeps on the bed with me or next to it. After a week this behavior dies down to normal levels of attention and he goes back to sleeping in the basement or the living room. His brother doesn't exhibit this behavior even though he is equally affectionate.

Rate of Jira tickets closed does not equate to "quality product". It (optimistically) means "lots of work done". The numbers you're looking for would come from user product feedback and bug reports, but it also comes subjectively from the product owner/leader's assessment of the product's performance. That's the nuance that leadership deals with every day and which we often overlook as good little Jira closing robots.

Assuming you're joking, ECS here stands up Elastic Container Service.
And we'd all keep drinking coke products as long as they express the correct opinions and put flags on their pfps when appropriate on twitter.
I was not convinced by this article that ECS was the right choice. It felt more like a contrarian choice.

> ECS is also relatively simple and not so far from their Docker-compose setup, but much more flexible and scalable. It also enables us to convert their somewhat stateful pets to identically looking stateless cattle that could be converted to Spot instances later.

Have you ever built something in ECS? I have, and it is missing HUGE SWATHS of the convenient functionality that EKS provides. It lacks the network effect of being a widely-used product, so searching for issues is a constant issue. It breaks and nobody knows how to help.

"Not far from their docker-compose setup..." What are you even talking about? ECS is massively more complex than docker-compose and the main similarity I see between them is that they both run docker. It's similar to docker-compose if you ignore the fact that you need permissions, load balancers, networking, etc. Which is the hard part, NOT running some containers on EC2, by the way.

It has it's own bizarre and verbose container deployment spec that is less portable, less flexible, less feature-ful, and less widely used than EKS.

> ECS will also offer ECS container logs and metrics out of the box, giving us better visibility into the application and enabling us to right-size each service based on its actual resource consumption, in the end allowing us to reduce the number of instances in the ECS cluster once everything is optimized.

Something you also get with EKS. So half of the reasons you have claimed ECS was the right choice are now in the garbage.

What you DON'T get with ECS is awesome working-out-of-the-box open source software like External Secrets, External DNS, LetsEncrypt, the Amazon Ingress Controller, argo rollouts, services, ingresses, cronjobs... I could go on and on.

They are going to try and hire DevOps engineers, and they will all have to ramp up ( and likely complain about ) ECS instead of having people walk on already prepared and ready to start implementing high quality software on a system they already know.
