dangom commented on Building Document-Centric, CRDT-Native Editors   blocksuite.io/blog/docume... · Posted by u/rapnie
PaulRobinson · a year ago
Document-centric workflows were once the great promise of the future, and inspired Microsoft's OLE, Apple's "Publish and Subscribe", and then OpenDoc.

I remember reading a computing magazine in the early 1990s that promised a future where we would decompose applications and the OS would only really worry about a file, and you would bring functionality to the file.

You would in essence be able to build your own perfect word processing environment (for example), by bringing Company X's editing tools, Company Y's grammar checking and spelling tools, perhaps some embedded spreadsheet tables from Company Z if you were writing business reports, and so on.

We kind of have this a little today with browser extensions, in that we can extend functionality onto a webpage we're viewing, but our environments are still very application-centric and not workflow or content-centric at all.

This article shows an application that _might_ be interesting (and the CRDT is a mandatory requirement in today's environment), but while the OSes we use require us to do this sort of work in a windowed application, it won't quite appeal to me as having the full potential.

I often think back to that article as it made me quite excited about the future of user interfaces and how operating systems could support workflows tailored to the individual and the task they wanted to achieve. This was all in a time when we had moderately novel ideas in OSes popping up (Windows NT, OS/2 Warp, NeXT, etc.), and just before the web was starting to get popular.

I think the content-centric model you are describing has been alive and thriving since at least the late 70s in Emacs.

But they've worked very hard at shielding most users from that complexity. And the end result - making multithreading a truly viable alternative to multiprocessing for typical use cases - will open up many opportunities for Python users to simplify their software designs.

I suppose only time will tell if that effort succeeds. But the intent is promising.

Do you have any references or examples that describe how this simplification would come about? Would love to learn more about it.

I don't have any science behind this, but it makes sense that training more complex motions would trigger greater brain improvements.

Dance vs basketball or some other high coordination/skill activity might have less disparity than say dance vs. exercise bike.

dangom · a year ago
Depends on what you mean by "improvements". Is it coordination? Is it sustained increased blood flow? I would imagine that different bike exercise regimens could induce more variation in fitness than the comparison dance vs exercise alone.
dangom commented on Short-term fasting induces profound neuronal autophagy   ncbi.nlm.nih.gov/pmc/arti... · Posted by u/Frummy

One can always find positive and negative outcomes related to any intervention to a biological system. Fasting is no exception. The question is when and where is it beneficial, and what are the trade-offs. I'm sure if one has a clean, healthy diet, and consistent sleep and routine, it likely does not matter in the long run at what time one decides to eat or not eat. If the effect size were noticeable we'd have seen it already in smaller samples.

If one is overeating, or eating garbage all the time, then I'd hypothesize fasting to be beneficial by giving the biological system a break to try and bring itself back to a better steady-state without so much forced external input.

This keeps coming up. Is this depth story not simple to fact check with simulations? Are we missing something?

This is neat, but (and I say this as a 14+ year diehard Emacs fan and average-skill elisp hacker) this seems like a classic example of things in Emacs world being overly complicated.

I almost didn't comment because I hate to take a cool thing the author did and turn it into a negative, but I've been thinking a lot about this complexity lately because of a recent foray back into the Vim world.

I've been moderately Vim proficient for most of my career, and decided to give things another try now that Neovim and Lua-based configuration is so popular. I was astounded by how simple and straightforward it was to get an LSP + Treesitter + DAP + Telescope, etc setup working, and with a clean and relatively compact amount of code.

It just felt so uncomplicated, and everything just worked. No using temporary bridge packages for treesitter modes, while still needing to copy over your mode hooks and set parent keymaps. Fuzzy completion that is consistent and doesn't depend on which company backend is in use. DAP mode layouts that consistently work as well as e.g. VS Code (I still cannot get Python's Rich library progress bars to show up in dap-mode output on emacs).

I still prefer Emacs, but am glad I went around the block with Neovim. It's inspired me to start a ground up rewrite of my Emacs configuration in the quest for simplicity, so maybe there's hope for my config yet.

Nice. Love vim too, but letting go of org mode is too much of a negative to justify a switch. I know I could use Emacs just for org mode, and vim for everything else, but that seems like even more overhead.
dangom commented on Contraceptive pills might impair fear-regulating regions in women's brains   blog.frontiersin.org/2023... · Posted by u/geox

I appreciate that people are looking into this, and I think more research of this kind should be funded. However, one needs to be cautious when claiming an "impairment" in fear regulating regions from a measure of cortical thickness with MRI. For once, there is no evidence that a slightly thinner or larger cortical thickness means better or worse regulation of any kind. Second, morphology studies are susceptible to many sources of biases which are not really addressed in this study. For example, anything that affects hydration levels or causes a redistribution of blood and cerebral spinal fluid volume can lead to significant changes in measures of cortical thickness, since they will change the contrast between gray and white matter that drive cortical thickness measurements.

Changes in thickness have been found even when comparing people scanned in the morning and in the evening [1]. Any drug intervention could be expected to cause physiological changes that could act as confounds. Also, in the discussion one reads: "Interestingly, no lasting effects of combined oral contraceptives (COCs) use were detected when comparing the four groups." This suggests that the changes could be driven by physiological changes instead of permanent changes in brain circuitry.

It would be great to see a follow up study controlling for potential confounding effects (for example, measuring baseline perfusion, blood pressure and controlling for time of day effects and usage of other drugs), and expanding the study with functional tests that involve fear regulation.

What are the best practical ways of keeping away or killing mosquitoes, midges, black fly and house flies etc?

I've heard of propane burners called 'mosquito magnets', I've heard of chemicals you spread or leave out in traps, I've heard of sprays and tape. Obviously different things work for different pests. I've seen people wearing face nets and hoodies.

Anyone got any real experience and recommendations?

Does anyone know why the decision to ban it? Was it a move that had a relatively higher injury rate compared to other high difficulty moves?

Why does an suv not have visibility in front of it?
dangom · 2 years ago
Because we can safely assume that under normal atmospheric conditions and within the distances we are talking about, light travels in straight lines and the SUV is too high thus blocking some of it from reaching the drivers eyes. I can't pull the sources now, but there was a study discussed here on HN a couple months ago showing an analysis of how this plays out.
