The argument rides on the well-known Goodhart's law (when a measure becomes a target, it ceases to be a good measure). However, it only puts it down to measurement problems, as in, we can't measure the things we really care about, so we optimize some proxies.

That, in my view, is a far too reductionist view of the problem. The problem isn't just about measurement, it's about human behavior. Unlike particles, humans will actively seek to exploit any control system you've set up. This problem goes much deeper than just not being able to measure "peace, love, puppies" well. There's a similar adage called Campbell's law [0] that I think captures this better than the classic formulation of Goodhart's law:

The more any quantitative social indicator is used for social decision-making, the more subject it will be to corruption pressures and the more apt it will be to distort and corrupt the social processes it is intended to monitor.

The mitigants proposed (regularization, early stopping) address this indirectly at best and at worst may introduce new quirks that can be exploited through undesired behavior.

In the process, acting somewhat like a generalization of the problem it describes: overly precise and narrow approaches to "improve" ineffable qualities. But the author seems to understand that - he comments on the absurdity of some direct transfers of ML methods to real world problems. I think he just added a bunch of not necessarily well solvable, but particularly suffering from "overfitting", example problems. It's a food for thought article, not a grand proposal.

The main reason I stopped using programming ligatures that much is that many languages actually support Unicode characters in the source code, and this is actively used in some projects I work on.

It then becomes important to see the difference between ASCII approximations and real Unicode symbols, since this is relevant e.g. when searching for a symbol in your code base or to see at a glance whether usage of Unicode vs. ASCII etc. is consistent.

The only spot I still kinda use such a feature (prettify-symbols-mode specifically) is in LaTeX, where Unicode math is more rare and long equations become nearly unreadable without some kind of rendering in the source code.

Seconded. My use case might be running my own Ruby scripts faster, but they don't need to run any faster so it's not worth the trouble of setting up a development environment, especially one that requires a compilation step.

It would be a totally different thing if it could run Rails, which is one of the things I do in my job. The speedup would probably justify using it, especially when running tests on my laptop. My customers are perfectly happy with the performance of Rails on their servers. Same with the ones using Python with Django.

They don't have to advertise. Some outfit may gift you a week of timeshare, or a hotel concierge might be in cahoots with timeshare salespeople, and offer you boat rides or whatever in exchange for a sit with the TS salespeople. They push as if their lives were on the line for each sale. It's intense. You can find touts for the salespeople offering goodies at certain airports, lining the only exit aisle.

Only TS I recall unloading was the one in Waikiki that was sold to another corporation. Weeks went poof, but so did the fees.

Yeah, every single example listed looks like gaming of bad metrics. Framing it as overfitting is unproductive, IMHO, and discounts the essentially adversarial context.

> when a measure becomes a target, it ceases to be a good measure

If you ask someone "could you give me an example" you will see that in the example the measure that becomes a target is already a proxy. Even the example that the author presents, the good that cares a lot about testing its students... How does the school test its students? With exams. But that's already a proxy for testing students knowledge...

But overall excellent article.

> Those price-fungible goods and services you name capture surplus value to the seller. A Georgian tax on such goods captures that surplus value, limits price growth, and could further finance UBI/GBI and other public welfare projects.

Big oof. This rapidly turns into market participants leaving the market because the returns associated with the "price-fungible goods and services" (whatever precisely those are) are poorer than those not denominated in the currency.

Mass distribution of currency only leads to devaluation of currency. The entire premise of Georgism isn't about fixing wealth inequality: it's about forcing resources that are physically finite with no replacement (namely land) into productive use.
> All the files are local

From what I’ve seen, most people tend to use cloud document platforms. Microsoft has made Office into one. This has been the steady direction for the last few years; they’ll keep pushing for it, because it gives them control. Native apps with local files is an inconvenient model for them. This sadly applies to most other types of apps. On many of these cloud platforms, you can’t even download the project files.

> You can't really have an AI for your local documents on the cloud because the cloud doesn't have access

Yes, up to the cloud it all goes. They don’t mind, they can charge you for it. Microsoft literally openly wants to move the whole OS to the cloud.

> Same logic for businesses

Businesses hate local files. They’re a huge liability. When firing people it’s very convenient that you can just cut someone off by blocking their cloud credentials.

> We've observed the same on web pages where more and more functionality gets pushed to the frontend

It will never go all the way.

> One could push the last (x) layers of the neural net for example, to the frontend, for lower expense and if rightly engineered, better speed and scalability

I’ll believe it when I see it. I don’t think the incentive is there. Sounds like a huge complicating factor. It’s much simpler to keep everything running in the cloud, and software architects strongly prefer simple designs. How much do these layers weigh? How many MB/GB of data will I need to transfer? How often? Does that really give me better latency than just transferring a few KBs of the AIs output?
Chicks are chickens, just like puppies are dogs, kittens are cats, etc. "Chicken" is the name of the species: https://en.wikipedia.org/wiki/Chicken#Nomenclature

If you'd said "hens" you'd have a stronger point, but then you'd need to be talking about chicks and hens (and they could still cross whatever adulthood threshold you like within the week, as you didn't specify how young they are - "new" could just mean new to the farmer).
This is a really fascinating graphical piece!
The branding is incredibly confusing, but: Hotwire (https://hotwired.dev/) is a set of ideas about how to build dynamic web UI (“HTML over the wire”), and the Turbo, Stimulus and Native frameworks are complementary implementations of those ideas in JavaScript and native mobile code. You can use all, some or none of them to build a Hotwire-style app.

The three frameworks originated in Rails apps, so they have good Rails integrations, but there’s nothing Rails-specific about them and you can use them in any environment where HTML is sent from server to client, even a static web site.

There's no timeout on SSH sessions by default.

In good conditions you can go months without sending a single byte of traffic between an SSH server and client and both will pick up the connection just fine when it's time to communicate again.

You could cut off traffic between them for any amount of time and they would be none the wiser as long as the network connection is back to normal when they finally try to send traffic again.

(I had SSH sessions in a QA lab persist as if nothing had happened after the connection between the endpoints was down for almost a week while we replaced the aggregation layer routers. They never saw a link state change since the access layer switches were up the whole time. They never attempted to communicate while the connections between those were down, so there was never any problem as far as they were concerned.)

The keepalives and connection checks and so forth are mostly to account for things like stateful network gear (firewalls, NAT routers, etc) between the endpoints that will cease relaying traffic between them if they are quiet for too long.
This fact is what scares me most about economic populism in the USA. I'm not concerned about higher taxes: I'm concerned people look at the college market and see the problem as lack of subsidy, not about excess capital availability.

The PSU also powers the motherboard (keep in mind all those power hungry USB-C PD peripherals), CPU, cooling (fans and AIO liquid cooling pumps), storage, and RAM. Furthermore, when building a PC one would keep some buffer of a few hundred watts in the event that one would want to down-the-road add another GPU (or two (particularly for ML work)) to spare PCIe slots of the motherboard, or simply future-proof the PC for future more-power-hungry GPUs.
That would assume your only target measure is efficiency, which would be a silly think to target in exclusivity of everything else.
The problem is that Apple doesn't open-source their drivers and firmware, so those things won't get security updates even if you're using a third-party OS that otherwise does. If I were in charge, companies would be obligated to keep providing security updates for all hardware they sold until they either did open-source everything, or provided full refunds to everyone who ever bought one.
This reminds me of something I wrote in Tcl at my previous employer - a little utility that could decode an in-house data format and display it in an understandable way. Quite a few other people found it useful for debugging issues.
When you get to scale like this, I wonder if the access patterns of the application and its data might be best served by a custom data retrieval and storage application.

I may be wrong but I just wonder if efficiency is lost to the generalized nature of any data storage system.

The other question that comes to mind is, to what extent have the developers made a systematic effort to optimize how data is stored and retrieved? If you’re building a gigantic back end system and simply accepting that the system load is what it is then you might be missing a chance to dramatically impact the size of the task of managing that data.
I helped a friend do the novice exam, which is really quite easy these days and even permits the use of some HF bands (which I've personally never even have used with my full license from the 90s - I live in a city apartment and simply don't have the space for the required antennas)

I can really recommend doing it. If you have some knowledge about electronics and some affinity for it, it's pretty easy. You'll need to study some of the regulations and stuff but it's very doable.

When I did mine in the 90s the exams were still pretty hard but even then I studied for a day and passed. Of course having all my existing knowledge of electronics and 5 years of CB experience did help a lot. But overall i just coasted through it. People worry about it too much I think.

> But access to the autoupdates infrastructure isn't part of that deal.
If wp-engine want to change customers for access to that it's not unreasonable to expect a contribution.

If they went about it in a fair and equal manner, sure. So far the public evidence looks like the access denial is retalitory or perhaps even an attempt at extortion over the larger dispute.

The api may not be part of tje GPL, but it still seems like they offered it freely and encouraged people to use it with no expectation of anything in return. Encouraging someone to use X, then getting mad at them over something unrelated, and abruptly cutting off X with no public notice is pretty unprofessional. Given their corporate structure, maybe even illegal.
That depends on what your scheduler does. Having one virtual core doesn't necessarily mean you always get the same physical core.

Also you said "a lot of workloads" so yes probably more containers than cores.
Nope. Didn't change the schema, mainly added read coalescing and used ICS. I think the big thing is when Scylla is processing a bunch of tombstones it's able to do so in a way that doesn't choke the whole server. Latest Scylla version also can send back partial/empty pages to the client to limit the amount of work per query that is run.

> Is there a good term for reality conflicting with claims of hallucination and misinterpretation?

I can't think of a good one yet, I'm sure a year from now there will be one commonly used.

What triggered the assumption on my end (not the comment you're replying to) was your statement "Wifi7 has 3-D radar features for gestures, heartbeat, keystrokes and human activity recognition, which requires the NPU inside Intel SoC. The M.2 card is only a subset." - I initially couldn't find any good references, because Google was so filled with ChatGPT'd SEO spam (notable a bunch of circular references citing a Medium article, itself obviously LLM'd).

Apologies for my mistake there. You seem to know quite a bit about the subject. I'm definitely constantly on-guard with any claims these days, especially ones that have potentially terrifying implications, without a primary source.

Python development is done in public so you can just benchmark against the development version to see its improvement. In fact, daily benchmarks are already posted to [1]; it indicates around 20% improvement (corresponding to 1.25x in the table) since 3.10. The only thing you can't easily verify is that whether GIL was indeed historically necessary in the past.
