Very natural also in money/investing applications. Passing to log scale asset prices follow random walks in several finance applications and behave much better in this scale. Options price formulas by rote memory are a bit of a mess because one does a log-calculate-exp kind of thing that distorts the streamlined rationale of the inner simpler calculations. Geometric means (used in CAGR, compound aggregate growth rates, for yearly returns) become just means (=arithmetic means) in log scale.
Agreed. Any stock app that doesn't plot stock prices in log scale is considered by me to be an amateur app. My favorite litmus test for stock apps is to view the ten-year price history for UVXY. If it doesn't look roughly like a straight line the app is for amateurs. The iOS built in stock app fails this test. The Schwab app passes this test.
I've heard of people who have basically converted all their financial or investment spreadsheets to use log scale, but I've never seen an example or a demo.
Our lab pcs run about that, with password protected BIOS. DOS has some filenames wired to devices (con, aux, prn)... as in linux /dev. Don't recall why but one time I summoned "echo kk > clock$" and not only did the real time clock lose sense of time, but upon reboot the bios was struck with bios checksum failed, bad crc, password protect forgotten and bios open to any mischief.
Much agreed, and this is prompting me to experiment with other search engines to see if they cut off also the interesting humans sites. With todays google I feel herded.
Have you dug a bit in the concept under wolframphysics.org? Discretization of PDE equations is interesting and some generating-functionology/combinatorics can be spotted more or less over there. CAs can enter anything under the computational umbrella, question being how sleekly. Have they achieved something already, do you share their interests? (you said "ama")
Ha, well, I've mostly successfully dodged the various Wolfram-science questions so far. I just finished reading a book on cosmology -- VSL theory -- but honestly a lot this kind of thing seems to be way too far above my personal abstraction ceiling. I can't tell whether some of these ideas really even mean anything at all, or if it's just somebody who is better at waving words around than I am.
This is wandering off of the Wolfram physics project a fair distance, but it's hard to see how space could be quantized in a Fredkin "Nature is finite and digital" kind of way, without the underling "grain" of the universe becoming obvious in some kind of experiment, and/or without causing deep contradictions in various experimentally well-supported relativistic effects that require that there isn't any such thing as a unique fixed frame of reference.
But quite possibly that's just a failure of imagination on my part, not anything wrong with the actual theories in question -- I'm probably complaining about some apparent implausibility two levels above or below where the information is actually flowing. And there are certainly all kinds of properties of our physical universe that are quantized in one way or another, for utterly mysterious reasons.
Long story short, there is certainly still room for some big surprises in theoretical physics, and I'm not about to claim that I'm clever enough to rule out any of these wild options.
I want all local, future proofish things. A pdf library and a heap of markdown notes. Windows, once prepared, gives me a local search engine of contents and metadata queried via Flow Launcher. I use a custom protocol handler to have file URIs relative to a configurable basis (so URIs remain valid if synched elsewhere). Use files of URL extension that are text files but intepreted by Explorer as symbolic links (being text makes them play well with sync), so the same file can appear in many places of the file tree hierarchy (ground organizational principle).
Now that djvu JBIG2 patents expired I jotted a script from parts to convert djvu to pdfs much better than earlier alternatives (with converted file size swolled a typical mild 66% more than djvu). I read pdfs with sumatra that has customizable external "viewers", that means invoking stuff on the pdf page with alt_f + key. One "viewer" copies a link to the current page in the clipboard. Now sumatra supports pdf annotations, made a couple scripts to convert annotations to pdf clickable hyperlinks (and other to undo that). So basically I have a pdf folder and a markdown folder (managed via Obsidian, if you ask) all interlinkable. I read, and copy and paste into markdown, and paste also a link to return to the source from the note. Pay mathpix suscription, there starts to be free would-be replacements. Use Mozilla reader mode chrome extension and print to pdf to save neat pdf versions of blog posts. Finally I have an e-ink e-reader (2nd hand sony dpt-rp1) and am just writing scripts to sync it with windows via an always-on NAS (the e-reader registers itself via zeroconf, and in the NAS via python one can hook a listener that will call unison two-way sync tool). Add also Omnivore.
This e-reader is quite dumb and only talks to the world via propietary GUI app so I don't think it had a friendship with a selfhosted Calibre. There is a hacked python module to pilot the e-reader but some extra glue would be needed. In my case my data model is laptop first and then have backups on other places including NAS, after, so I prefer to have Calibre in laptop. I can map a NAS path to a laptop folder and Calibre sees it as a device, with a nice send-to-device button. So I just need to end the glue to sync the e-reader with the NAS. Calibre automatically converts EPUBs to pdfs. Having bought a Kindle DX back then, I can even setup a Calibre DRM plugin with the Kindle serial number, buy an e-book in Amazon, click on the AZW file, and have a PDF generated automatically :-) For papers, I prefer to manage them separately.
For what I tried is like rclone bisync but without cloud awareness. Useful in a LAN context and with all maturity one can ask for. Rare it hasn't got more good rap.
I was almost amazed when instead of launching windows 3.1 running win.com one could run Borland DPMI host (that they used in their own 32-bit compiler toolchain), that stayed resident offering its API, and then one could run windows' KRNL386.EXE, that hooked with the DPMI host and booted windows.
None concrete I can think about, apart from understanding better the innards of windows boot with a whacky experiment. DPMI was an open spec, so this validated that in principle you could write your own DPMI host to make windows think it was running on top of a protected mode whose view to clients you could control and customize. But again can't answer to what avail.
