Wow, one of these should be at a museum or public institution.


Leibniz wrote "I have often said: 'Aurum latere in stercore illo scholastico barbarico'; {there is gold hidden in all that barbaric scholastic crap} and I wish that some skillful man could be found, versed in this Irish and Spanish philosophy, who would have the inclination and ability to extract what is good from it. I am sure his work would be rewarded with many beautiful and important truths".

I'm not pasting the walltext full quote, but there's also in it mention of Perennis quaedam philosophia. The first one? Don't have the book in digital, for the full quote in Spanish, Google sent me here: http://dx.doi.org/10.12795/Vico.2020.i34.03.

Yep while this manifest v3 ugly thing is putting me on the brink of jumping ship (I compromise by having two browsers), as for your concern I found that Chrome is going to allow blacklisting extensions for sites, so now I can turn them off for the few sites that I really worry to grant extension read access.

chrome://flags, "Extensions Menu Access Control" flag. https://developer.chrome.com/blog/new-extensions-menu-testin...


If you are fine with two browsers, maybe you could instead look into separate Firefox profiles with different sets of extensions. I have added "-p" to my Firefox shortcut so it always starts with the profile picker thing.


I concur. "Broken Code" book by Jeff Horwitz at the Wall Street Journal amply elaborates how business metric driven algorithms stir user attention at their convenience, that may or not agree with the user's. For one data point, I prefer to be gourmet than to be fed.


and mathpix


Wow. The Mathpix mobile app has support for reading two column PDFs as a single column.

You can't run it locally, though, right?


> The Mathpix mobile app has support for reading two column PDFs as a single column.

Mathpix is what gave the best results when I tried a whole bunch of OCR solutions on technical PDFs (multi-column with diagrams, figures and equations). It is brilliant.

> You can't run it locally, though, right?

Unfortunately, no. Which is a shame because I also have confidential documents to OCR and there is no way I put them on someone else’s cloud.


Did you try marker? https://github.com/VikParuchuri/marker

I haven't tried olmocr yet and I now realize my 8GB GPU probably won't cut it, as it used a 7B param VLM model under the hood.


> Did you try marker?

I did not, but I will. Thanks for the pointer!


The irony is that this will zero the e-book purchases of people that read only in unsupported devices.


There is also vintageish SCXML underwritten by the w3c, with the panoply of xml friends (an xsd schema hence validator, xpath queries and xslt transforms). Also being part of the uml chart family it should be xmi-borne, if you wondered.


This! you can default to it in Chrome: settings->engine->search engines, edit default one and insert udm=14 magic fragment in the query template.


It is an immune system overreaction causing inflammation causing then bronchial constriction and of more ramified aereal ducts reducing total air vol per breath. Inmune causes are routinely tested to be of allergic origin for external allergens and a test panel is common to be done measuring reaction to agents such as dust mitels, pollen, animal fur. Often one cannot pin a single cause. Bad air quality (smog) or cold can be triggrers, and contradictorially unusual physical effort demands can trigger it reducing O2 availability just when more is what the situation demands. It's a self-immune problem in the end, not that well understood.


Bohr was a big shot, Nobel prized establishment authority. In Weimberg QFT book he recalls a fragment of Dirac's memoirs:

"I remember once when I was in Copenhagen, that Bohr asked me what I was working on and I told him I was trying to get a satisfactory relativistic theory of the electron, and Bohr said 'But Klein and Gordon have already done that!' That answer first rather disturbed me. Bohr seemed quite satisfied by Klein's solution, but I was not because of the negative probabilities that it led to. I just kept on with it, worrying about getting a theory which would have only positive probabilities."


Is there a relationship between the negative probabilities of Klein and the negative energy of Dirac? Did his formulation just move the problem? If so, does it imply anything? Like are probability and energy related?


Klein-Jordan equation does have both problems, negative probabilities and energies. Dirac equation solved negative probabilities and now predicts positive probabilities for both positive and negative energy states. But the negative energies problem still exists and Dirac used different interpenetration to explain them and did not get rid of them (which we knew later that this was the correct things to do). So he came with the famous negative energy solutions interpreted as antiparticles.


It’s worth mentioning that, brilliant as Dirac’s “sea of filled negative energy states” picture was, no one believes that interpretation now. The Dirac equation is better seen as the classical equation of motion for the Grassmann-valued electron field (just as Maxwell’s equations are the classical eom for photon field). There are only positive-energy states (=quantized excitations of the field). I do think popular accounts should begin mentioning this in order not to keep reinforcing the old Dirac sea interpretation.


> no one believes that interpretation now

I know of at least one (tenured) person that does, at least to some degree: Felix Fenster at Regensburg University. When I met him years ago, he said taking the Dirac Sea interpretation seriously was what caused him to come up with his own program for a theory of quantum gravity, called Causal Fermion Systems[0]. I haven't looked into his theory in detail but I did find a reference to the Dirac sea[1]:

> In order to obtain a causal fermion system, we first have to choose a Hilbert space. The space of negative-energy solutions of the Dirac equation (i.e. the Dirac sea) turns out to be a good choice. […] As a side remark, it is worth noting that the Dirac sea vacuum is to be seen as an effective model describing a particular minimizing causal fermion system. It is one particular physical system that we can describe as a minimizing causal fermion system. But we should really only think of it as an effective description, in the sense that it describes only the macroscopic structure of spacetime, whereas its microscopic structure on the Planck scale is essentially unknown. […] The idea of the Dirac Sea did, however, play an important role in the conception of the causal fermion systems framework, and most of the existing literature is written with that point of view in mind. A more detailed motivation for why it is a natural starting point can be found here[2].
