STIPENDI NON PAGATI DA 2 MESI, EDILI OCCUPANO GRU DIETRO DUOMO

Oggi una trentina di operai edili si sono presentati nel cantiere di via Silvio Pellico, dove è in corso una ristrutturazione, per protestare contro il mancato pagamento degli stipendi da due mesi. Quattro di loro hanno occupato una gru mentre gli altri li sostengono da sotto.
Si tratterebbe dell'ennesimo caso di catena di subappalti che farebbe capo, in questo caso, a COIMA, gigante immobiliare e vero "padrone del vapore" di Milano.
La goccia che avrebbe fatto traboccare il vaso sarebbe stata l'intimazione fatta agli operai da parte dell'azienda subappaltatrice di non presentarsi in cantiere oggi.
La pratica dei subappalti ha lo scopo fondamentale di ridurre selvaggiamente il costo del lavoro e deresponsabilizzare i datori di lavoro di tutto ciò che non funziona.

This is wild.

❝In 2008, a Mexico City metro station was the site of an hours-long fight between emo, punk, and goth groups.

In the mid-to-late decade of the 2000s, subcultures in Mexico were often referred to negatively as “urban tribes,” and many were united by considering emos, the newest tribe, as their enemy. The emo subculture that reached its peak in this decade differed from the “original” emo movement of the 1980s and many of its characteristics were seen as having been plagiarized from early subcultures. Glam rock pioneered the androgyny, the dark and frizzled hair owes a lot to new wave and goth, while their music was similar to the pop-punk of the turn of the millennium.

Hatred against emos was widespread in many countries, mainly by other “tribes” such as goths and punks, but in Mexico and its capital city, the animosity was particularly commonplace and strong. The aforementioned androgyny might have been crucial in the reaction towards this group of people, as homophobic slurs and attitudes were often incorporated into anti-emo sentiments. Two years before the “war” in 2008, another well-publicized altercation occurred in the Metro Insurgentes roundabout between emos and punks, which led to police intervention.

The Metro Insurgentes roundabout is one of the main transport hubs near the City’s Zona Rosa (Pink Zone). For decades, it has been a crucial meeting point for countercultural and LGTBQ+ movements. While generally peaceful and tolerant, on March 15, 2008, a large gathering of people belonging to the emo subculture found themselves attacked by a group incorporating members of the city’s punk, neo-rockabilly, and goth tribes (locally known as “darketos”).

The conflict was estimated to have lasted up to five hours, on and off, but its definitive end came about in appropriately absurd fashion. While there was police intervention to prevent any major injuries, the actual end of the confrontation came about when a group of Hare Krishna followers entered the roundabout, inviting both factions to join in with the chanting and dancing. Even if they did not manage to fully incorporate the crowd, their presence did help in calming and dispersing most of the people involved.❞

There's a trick I pull on my #ADHD brain that works every time.

Whenever there's a task I don't really want to do, I tell myself "okay, we just have to START the task, and then we can stop after <small timespan>" And then, without fail, I end up completing the task, or at least making serious headway on it.

This is because I have a huge problem with task-switching. Once I am ON task, I find it difficult to stop, but I have to get there in the first place.

I hope this never stops working.

Lars Wirzenius mastodon (AP)

I'm not ADHD, but I use a similar trick: I sometimes find it really difficult to do some tasks, but I can often get around them by identifying the smallest step to move that task forward, however little. Like, to pay a bill, my first small step might be to find the envelop that contains the bill. Not open the envelope, not even put it on my desk, just checking that the envelope still exists.

Or find a pen with which I can write "paid" on the bill, once I've paid it.

A little bit of math can go a long way. The design of a system can be hampered not only by having too little mathematical analysis go into it, but also too *much*.

One familiar example of this is with password requirements in cybersecurity. Mathematically, the more complex that a password is required to be - for instance, by mandating minimum length, special characters, or no reused passwords - the more secure the password becomes. However, make the requirements too complex, and users and service providers will then seek workarounds to the complex requirements, such as easy ways to reset or recover the password, or storage of such passwords in insecure systems - that in fact can serve to *decrease* the security of the overall system, rather than *increase* it. Overoptimizing on just a single metric - the security strength of the direct user/password login system - can serve to compromise the broader objective - a textbook example of "Goodhart's law" in effect en.wikipedia.org/wiki/Goodhart… . Roughly speaking, the security of this direct entry method should be strengthened to be comparable to the security of alternate entry methods, but beyond that any further strengthening tends to be counterproductive. There is little point putting in more locks on the front door of a building beyond the first one, if the windows are unsecured, and in fact doing so may even lead to a dangerous false sense of security. On the other hand, if the windows are harder to access than the front door, then putting at least one lock on the front door makes excellent sense. (1/3)

In AI, one instance of this principle is in Rick Sutton's "bitter lesson" incompleteideas.net/IncIdeas/B… . It is intuitively obvious, and initially somewhat successful, to automate a task by carefully designing mathematical algorithms tailored to the specific domain knowledge of the task at hand. However, for a surprisingly large number of tasks, we have learned that even more progress can often be achieved by applying relatively low-tech but general purpose mathematical methods, such as gradient descent and backpropagation, but with large scale investments in data and compute, rather than in tailoring. One example I have seen recently is in the development of cheap analog-to-digital converters (ADC) for sensor networks. Traditionally, ADC circuits are designed from classic electrical engineering principles, using mathematical results about ODEs, resonances, Fourier transforms, and so forth to obtain reasonably efficient circuits with theoretically guarantees on performance. But in environments (such as sensor networks) where some failure rate is tolerated, and the goal is to obtain fast and cheap analog-to-digital conversion at scale, it turns out to be better to simply train a neural network to design an ADC circuit without inputting any domain knowledge (such as Fourier analysis), and use the resulting circuits in the sensors. This is not to say that domain knowledge is completely useless - for instance, physics-informed neural networks can greatly outperform standard neural networks in many physical contexts - but one has to know how much of it is appropriate to apply. (2/3)
Terence Tao mastodon (AP)

Even within pure mathematics, we have learned that sometimes the best way to solve a problem is to abstract away information that one would intuitively think to be highly relevant. Much of the progress in analytic number theory, for instance, has been obtained by adopting the perspective that strongly number-theoretic structures, such as the set of primes, should in fact often be treated as much less structured objects, for instance as a rather arbitrary set of numbers obeying some minimal set of combinatorial properties. Abstract too much, and one no longer has enough information to solve the problem; but with just the right amount of abstraction, the problem can move into sharper focus, suggesting the right set of techniques to attack it, and also exploiting the freedom of the setup to perform additional transformations that would not have made sense in the initial setting.

I sometimes like to joke that applied mathematicians need to know the first two chapters of every pure math graduate textbook, but after that the subsequent chapters may have little (or even negative) value to them. On the other hand, the quest to locate Chapters 3-12 are often what made Chapters 1-2 the perfectly polished and useful gems of mathematics that have such broad utility... (3/3)

I really like the thread that you're pulling on here, which aligns with your blog post on "stages of mathematical development", and i think both are true of all specialisms

All progress seems to have two stages, accrue -> consolidate, which repeat (or don't) through time. We tend to confuse accrual (and accrual alone) as *real* progress; when it is the consolidation stage which matters more, because consolidated form is more stable, in that we can build upon it. which is *real* progress

The first stage of specialisation (the second of your post) is accrual, of special details, which we deem existentially significant, and subsequently tend to parse everything by those forms, almost exclusively. But the territory of specialisms is not isolated -- in nature nothing exists alone

The second stage (the third of you post) begins when we learn the plurality of significance of form -- that other specialisms/ ways-to-interpret the same form (or parts thereof) exist; and with each additional interpretation, an essence, the intersect of both, equates to a new generalisation, which is simpler, and which allows us to notice that the surface detail obsessed over by specialists is only part of the whole story

In this way, we can think of all special-domains as delta, to a respective/ relative general-domain, of relative simpler forms

And the interesting thing is that, essences being general, are fewer, and common across different phenomena: so a universal general-domain of essential forms, which all special-domains recontextualise

The implicit point, is that the path to unifying knowledge, is not by union, but by intersect: radical simplification

Which is cool

going to fawn over Standard Ebooks site standardebooks.org for a minute here

So aside from providing beautiful ebooks of public domain books, the site is blazing fast serving pages for so many books, and it's all static pages:

alexcabal.com/posts/standard-e…

Then look on a page for a book. There's a render of a book with the cover, the books at like an angle and if you hover over it the book floats a little.

Turn off javascript and the pic still renders and floats a little. If you right click and say open pic in new tab just the unaltered cover comes up.

Which means all the magic to take the cover and turn into a render of a book with a floating animation is all done in CSS.

And even better, go to a typical book. Typical thickness in that render. Then go to a big book, like The History and Decline of the Roman Empire.

standardebooks.org/ebooks/edwa…

Look at that chonk of a book in the rendering. So each book rendering is rendered the relative thickness of the book. Just such a cool detail.

edit: Oh, and go to the feeds for books:

standardebooks.org/feeds

There's OPDS (the catalog feed format), and RSS and Atom. Normally, you make the mistake of going to a feed URL in your browser instead of a specific program to read feeds, and you're punished with horrible XML.

But click on any feed link here and it's the nice looking HTML like the rest of the site. Is the server determining dynamically if a browser is reading the feed or a different program? But wait, isn't the site static?

That's right, all those feeds are also good looking HTML. Just brilliant work.

Turns out that LLM summaries are actually useful.

Not for *summarizing* text -- they're horrible for that. They're weighted statistical models and by their very nature they'll drop the least common or most unusual bits of things. Y'know, the parts of a message that are actually important.

No, where they're great is as a writing check. If an LLM summary of your work is accurate that indicates what you wrote doesn't really have much interesting information in it and maybe you should try harder.

«All’apice del suo potere, l’azienda fotografica Kodak impiegava più di 140mila persone e valeva 28 miliardi di dollari. Inventarono persino la prima macchina fotografica digitale. Ma oggi Kodak è fallita, e il nuovo protagonista della fotografia digitale è diventato Instagram. Quando Instagram è stato venduto a Facebook per un miliardo di dollari, nel 2012, impiegava solo tredici persone.
Dove sono spariti tutti quei posti di lavoro? E che cosa è successo alla ricchezza creata da tutti quegli impieghi della classe media? [...]
Instagram non vale un miliardo di dollari perché quei tredici lavoratori sono straordinari. Il suo valore nasce invece dai milioni di utenti che contribuiscono al network senza essere pagati. Per generare un valore significativo, le reti sociali hanno bisogno che moltissimi individui vi partecipino. Ma, quando ciò accade, solo un ristretto gruppo di persone viene pagato. Il risultato è di centralizzare la ricchezza e limitare la crescita economica nel suo complesso.
Invece di espandere l’economia creando più valore quantificabile, l’ascesa delle reti digitali sta arricchendo una minoranza relativa, spostando il valore creato dai molti al di fuori della contabilità.»

Yesterday was an important anniversary that supporters of #Russia (Soviet Union) do not like to remember:

September 17, 1939 was the day when the Soviets enthusiastically joined the Second World War, on the side of their ally - Nazi Germany.

That's why in Russia they don't like to talk about the Second World War, which they helped start.They prefer to talk about the Patriotic War, that is, the events after they were betrayed and attacked by their former ally.
