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)
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:
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.

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.

Also, I've been reading up on the history of the first digital computers (ENIAC, etc.). It sure seems like females had a big impact, although little credit. And yet there's Adm Hopper, who was a leader from nearly the beginning, and had great influence on the field. In her NSA lecture, she mentioned that she hired young people and told them to "try it!" instead of waiting for approval.
Why she's not more central to the history is a mystery. But a great role model.

Announcement: Firefish will enter maintenance mode
For those who have been supporting Firefish and me, I can’t thank you enough. But today, I have to make an announcement of my very difficult decision: As of today’s release, Firefish will enter maintenance mode and reach end-of-support at the end of the year. The main reasons for this are as follows.
In February, Kainoa suddenly transferred the ownership of Firefish to me. This transition came without prior notice, which took me aback. I still wish Kainoa had consulted with me in advance. At that time, some people were already saying that “Firefish is coming back”, making it challenging to address the situation. Also, since there were several hundred active Firefish servers at that point, I could not suddenly discontinue the project, so I took over the project unwillingly.
Over the past seven months, I have been maintaining Firefish alone. All other former maintainers have left, leaving me solely responsible for managing issues, reviewing merge requests, testing, and releasing new versions. This situation has had a significant impact on my personal life.
Frankly speaking, there are numerous bugs and questionable logic in the current Firefish codebase. While I attempted to fix them, balancing this work with my personal life made it clear that it would take ages, and I’ve started thinking that I can’t manage this project in the long run. Additionally, vulnerabilities have been reported approximately once a month. Addressing vulnerabilities, communicating privately with reporters, and testing fixes have proven overwhelming and unsustainable. Moreover, a certain percentage of users have made insulting comments, which have severely affected my mental well-being and made me fearful of opening social media apps.
I will do my best to refund the donations made to Firefish via OpenCollective, but that’s not guaranteed.
firefish.dev and info.firefish.dev will remain operational until the end of February 2025, after which they will return a 410 Gone status.
Server admins may downgrade Firefish to version 20240206/1.0.5-rc and migrate to another *key variant, or may fork Firefish to maintain.

reminds me of a MAXQ DSP I read about described as "opcode-less"
Every part of the chip would do something every clock cycle, so the "instructions" were nothing but a set of operands for all the units
Seems like quite a rare design now -- probably because scheduling, pipelining, and speculative execution have beaten it in total throughput
Amazing how silicon design has changed
