Update: it wasn't the ECB blocking gnome-calculator, it was an HTTP library regression breaking the connection to the ECB. Text in [] is incorrect, retained due to RTs etc.

[The ECB have remotely bricked gnome-calculator]

In the latest episode of "Why the 21st Century is impossibly stupid", GNOME calculator contacts the ECB on startup to get currency rates. It just hangs on startup if this fails, the whole calculator not just the currency stuff. [The ECB has blocked GNOME calculator].

To fix this, you can do "dconf write /org/gnome/calculator/refresh-interval 0", whatever tf dconf is, because when I tried it told me dbus-launch is missing, wtf that is, because it doesn't have a package. Turns out it's in "dbus-x11". I dunno why X11, because I use wayland, but I'm past caring at this point. I installed it and it worked.

Now I can calculate how much postage I need to pay for this parcel.

This is the color of infinite hotness.

This is the color something gets in the limit where its temperature approaches infinity. Of course you’d instantly be fried by gamma rays of arbitrarily high frequency, but this would be its spectrum in the visible range.

This is also the color of a typical neutron star. They’re so hot they look the same!

It’s also the color of the very early Universe!

This was worked out by David Madore, and you can find the details at my blog article, including a discussion of whether this is exactly the right color:

johncarlosbaez.wordpress.com/2…

Luckily, the alternative someone suggested is so close I can't tell the difference.

For computer screens and cell phones this color is approximately #98b5ff.

Two things I learned this week about #MSVC / #VisualStudio:

1. If vcvars64.bat is not behaving itself for some reason, you can set VSCMD_DEBUG=1 and it will print more diagnostics. 2 and 3 print more still: 3 is an "OMG redirect to a file and sort through it later" level of verbosity.

2. If you do this, the script stops for a noticeable time just after printing "Sending telemetry". One of the reasons it's so slow is that it's phoning home! You can set VSCMD_SKIP_SENDTELEMETRY=1 to turn that off, improving speed as well as privacy.

This is commented in one of the sub-scripts VsDevCmd.bat with the command
REM Send Telemetry if user's VS is opted-in
but, of course, I have no memory of seeing any opt-in box to tick.

today, i have IP-blocked the entirety of alibaba cloud’s IPv4 range (47.80.0.0/13, 47.74.0.0/15, 47.76.0.0/14). And you could ask - domi, what the hell, that’s kinda sorta a lot of addresses?

They’ve generated 9GB of access logs (!) and 230GB of generated tarballs (!!!) before I got to my laptop, investigated and ip-banned them. I’m positive that most forgejo deployments in existence wouldn’t survive this.

I've seen Alibaba too, had their IP range redirected to an infinite maze of garbage for a while.

They usually hit me with about 300 requests / sec from a few thousand IP addresses, with varying user agents, and happily ignore robots.txt, and don't care about 429 (with a Retry-After header) either. They just come and blast.

They seem to be very keen on ingesting garbage, though, and have made about 2 million requests against my system just yesterday.

Easily the most aggressive crawler I've seen, even worse than OpenAI, Claude, Google and Facebook combined.

Inside a combustion chamber, temperature fluctuations can cause sound waves that also disrupt the flow, in turn. This is called a thermoacoustic instability. In this video, researchers explore this process by watching how flames move down a tube. The flame fronts begin in an even curve that flattens out and then develops waves like those on a vibrating pool. Those waves grow bigger and bigger until the flame goes completely turbulent. Visually, it’s mesmerizing. Mathematically, it’s a lovely example of parametric resonance, where the flame’s instability is fed by system’s natural harmonics. (Video and image credit: J. Delfin et al.; research credit: J. Delfin et al. 1, 2)

There are definitely many real-world issues and problems where we could benefit from significantly more quantitative (and mathematical) analysis and thinking than we do currently. But, at the same time, there are certain dimensions of our modern society where we overcorrected for this, and allowed quantitative reasoning to dominate at the expense of other important modes of thought, or to be deployed in a highly imbalanced fashion.

As anyone who has encountered a word problem in their high school math classes knows, the first step in quantitative reasoning is to assign numerically precise metrics as proxies for one's goals, parameters, and variables. Most of our wants and needs are quite qualitative in nature: happiness, comfort, security, companionship, and the like. But these are too fuzzy to be optimized and analyzed by the mathematics of quantitative reasoning. Which, to oversimplify things, leaves us with basically two options: either use more qualitative modes of thinking, such as "gut feelings", emotional responses, or drawing on past experiences of similar situations, accepting any cognitive biases that result from doing so; or to create quantitative proxies for these goals, and then optimize those proxies in a more dispassionate (and hopefully more objective) fashion. (1/5)

1
Terence Tao mastodon (AP)

An ancient example is the invention of money, which allowed individuals and organizations to measure more and more of their capital in terms of a single number (in modern terms, one's "net worth"). Now, one could try to pursue one's material goals through the quantitative optimization of one's numerical net worth, for instance by analyzing different business strategies and selecting the one that would generate the most expected profit.

This strategy is initially very successful; below a certain threshold, there is a strong correlation between net worth and one's general happiness and wellbeing, and increasing one tends to increase the other. But as one gets closer to fulfilling both of these these objectives, the qualitative goal and the quantitative proxy begin to pull in divergent directions: pursuit of the next incremental increase in net worth can lead to increasing dissatisfaction, stress, and conflict in one's broader life. One begins to fall victim to Goodhart's law that metrics lose their effectiveness when they are targeted too strongly; after exhausting the "low-hanging fruit" of actions that improve both the metric and the underlying goal, one begins to perform increasingly unwise trades in which one gains in the direction of the metric at the expense of one's more fundamental goals. (2/5)

Terence Tao mastodon (AP)
One can counteract this to some extent by making metrics more accurate for (or at least, more correlated with) the actual goal; and, when inaccuracy or discorrelation is inevitable, to quantify the uncertainty in the metric and identify the sources of discorrelation as much as possible. For instance, in the early days of finance, only tangible physical goods could be assigned monetary value; but our increasingly sophisticated financial system is able to also monetize financial capital (e.g., stocks and bonds), intellectual capital, and even some very partial measures of social capital (e.g., "likes" on social media), although it still struggles with other types of capital, such as environmental capital. At universities such as the one I work in, there are attempts to update standardized tests for admission to better reflect the diverse ways in which students can learn and demonstrate potential, and adjust their weighting in admission criteria. And so forth. At the level of an individual human or organization, improving metrics can be an advantageous thing to do: all other things being equal, it is better to be guided by a more accurate metric than a less accurate one. But it can lead to longer term problems if only some of the members of a community are using sophisticated metrics, and others are not. (3/5)
Terence Tao mastodon (AP)
Take for example the activity of gaming. Fundamentally, the purpose of a gaming event is for the participants to have fun. But this is a qualitative goal, not directly measurable by a numerical quantity. One can then create more quantitative proxies for this fun: number of games or trophies won, score achieved, and so forth. A certain amount of emphasis on such quantitative metrics can initially increase the enjoyment of all participants. But one could always make the metrics more precise, focusing on ever more granular statistics: competitive ranking algorithms, "damage per second", and other measures of strategic efficiency. If all members of a gaming session are in agreement to compete on optimizing such metrics, this can also be an enjoyable activity (though of a somewhat different nature than casual play); but if only a portion of the players are playing this competitively, and others just wish to play casually, then the dynamics of imbalanced metric optimization can lead to a net decrease in the fun to be had by the players (most obviously for the "losers" of the game, but the "winners" would also experience some opportunity cost of fun, for instance through the reduced number of players available for future gaming sessions). (4/5)

Terence Tao mastodon (AP)

The ongoing process of "enshittification" in corporations and other institutions can also be viewed through this lens. Companies (and other complex organizations) have gained access to increasingly sophisticated metrics to measure their user activity, and now have the technology to optimize those metrics for their own benefit (in the near-term, at least). Initially, this sort of optimization can add value for both the provider and consumer of the service; but the majority of their customer base are not playing the optimization "game", and many would have initially signed up for an experience that was more qualitative and less optimized, and containing more of the intangible benefits that even the most advanced metrics fail to capture.

So, are metrics good or bad for individuals and communities? It is a very complex question. In some areas, we are under-using metrics; in others, we are over-using them; and in yet other areas, they are being deployed in too imbalanced a fashion to be beneficial in the long term. Perhaps what we need is more of a discussion of meta-goals and meta-metrics: not just how to pursue a goal or to optimize a metric, but to try to analyze (both qualitatively and quantitatively) how similar or distinct these two objectives actually are, and to locate a stable balance between them that can be broadly accepted within the community in question.

Kilian Stahl mastodon (AP)
I think this is a framing that is very... "problem theory" style, meaning it assumes everyone in society wants the common and we are merely disagreeing about the methods to achieve that. The term "enshittification" as defined by Doctorow describes a much more "conflict theory" idea: it's the result people acting in predictable incentive gradients. Publicly traded corporations have the incentive to extract the maximal amount of short term growth of revenue out of their users.
Terence Tao mastodon (AP)
That's true also, and designing metrics and incentive structures to reduce or mitigate such conflicts is certainly one of the "meta-goals" I alluded to. But I guess I wanted to focus on a slightly different point, which is that even when everyone's interests are aligned, one can still be led astray by an inappropriate under-reliance or over-reliance on metrics.
Questa voce è stata modificata (9 mesi fa)
Kilian Stahl mastodon (AP)
I suppose I don't see how the over- or underreliance of metrics is really a problem here, the actual issue seems to me orthogonal to that: companies are using metrics they need to optimize what they care for. Now there surely are cases where people use metrics badly, to disguise their lack of understanding behind mountains of data. But that's not really the issue here, even if everyone uses quantitative metrics exactly as much as needed to help their goal, enshittification would still occur.
Terence Tao mastodon (AP)
@KStahl I'd say that perverse incentives and inappropriate use of metrics are both contributing factors. For instance, there are certainly examples of companies who have acted against their long term interest by enacting changes to their service that improved some metrics (e.g., their stock price) at the expense of other qualities, such as consumer satisfaction and brand loyalty, that are arguably of much higher long term value to the company even if they were working purely in their own self-interest. It is also true that this self-interest may also genuinely come in conflict with the interests of their customers (or the environment, etc.), especially with a badly designed incentive structure and regulatory system, but I view this as a somewhat orthogonal issue.

Yes, and a related thought: as a physicist, I've always found it very hard to understand why anyone would think that they can express everything in monetary units, or any other single unit (like CO₂-equivalents). Some problems are inherently multidimensional, so even if someone does think it could all be quantified (and the non-linearity straightened out by using, e.g., abstract utils instead of dollars), it *still* doesn't make sense to collapse it all into a single one-dimensional metric.
Terence Tao mastodon (AP)

In principle, an efficient and liquid market does provide precisely this dimension reduction (and is one of the key distinctions between an economic system and a physical system). If one possesses a multidimensional vector of various goods and services, then by trading in such a market, one can exchange this vector for other vectors. If one makes the (sometimes justifiable) assumption that the efficient frontier of such exchanges forms a differentiable hypersurface around one's current state vector, then the normal to that hypersurface naturally determines the "price" of each good, and one can then measure (marginal) increase or decrease in one's effective wealth (modulo this efficient market) by the one-dimensional metric of taking the dot product with this state vector.

But for goods that are illiquid or only available in inefficient markets in which arbitrage opportunities exist, then this dimension reduction is no longer available, and price becomes a much more complicated notion (for instance, there can be non-trivial spreads between bid and ask prices). In particular, problems can arise when some goods are priced in a liquid fashion, but others (e.g., environmental goods such as clean air and water) are not; then optimizing value using market prices can lead to one sacrificing illiquid goods for liquid ones in a non-beneficial fashion.

@SylviaFysica - on a vaguely related note, I'm enjoying some ideas in Will Storr's book "Status Games", which posits that after satisfying some basic needs we're primarily motivatived by the search for status, which he loosely divides into:

• Dominance games: Status is imposed by force or fear.
• Virtue games: Status is awarded for moral behaviour and adherence to group norms.
• Success/competence games: Status is given for skill, talent, or achievement.

I think he'd claim the quest for money is, once basic needs are satisfied, largely a proxy for status - so, maybe some sort of mixture of a success game (money as a way of demonstrating success) and dominance game (money as a means to achieving dominance).

As with all pop psychology/sociology, there's lots of criticize about this, but I think a lot of economics could use a bit more attention to the underlying psychological/sociological aspects. More here:

Tony Vladusich mastodon (AP)

@SylviaFysica
I recently learned about the fallacy of the average pilot, which somehow eluded my awareness until then!

Collapsing complex multidimensional systems into single dimensional metrics is almost certainly always a bad idea. The representational volume of defined ranges over the space will occupy an exponentially smaller volume of the total space as the dimensionality of the space grows linearly. It follows that the inverse is true: a single metric can capture only an exponentially vanishing proportion of the total variance of the system as the dimensionality grows linearly.

mastodon.gamedev.place/@demofo…

Terence Tao mastodon (AP)
@TonyVladusich @SylviaFysica This connects with my previous post about effective dynamics. In situations where the law of large numbers applies, so that many of the fluctuations in the system largely cancel out, then it is possible for a low-dimensional secular component of the variance to dominate the high-dimensional random fluctuations as far as the effective dynamics is concerned, and so low-dimensional models are reasonable to assume in some circumstances. But certainly not in all cases.
Michael Chavinda mastodon (AP)
this reminds me, in part, of the argument in prosperity without growth.

"Given the opportunity, gamers will optimize the fun out of your game."

Thanks for sharing your thoughts, professor! Another banger post, as usual.

Terence Tao mastodon (AP)
@juanrloaiza @KStahl I would still argue in such cases that while that corporation may well be locally optimizing various metrics such as quarterly profit, they are not globally optimizing for "success" (however such a fuzzy term is defined). In particular, there is the substantial opportunity cost of the company not pursuing the alternate path, in which they maintain high quality standards and build a fervently loyal base of customers who are willing to donate their time and labor to promote the brand and improve the product, which could well lead to a theoretical company that is far larger and more successful than the profit-maximizing actual company. But such opportunity costs are almost impossible to measure - they require analyzing a system state extremely far from the actual state - and so would not be picked up by any existing metric used today.
