<p>I have been looking for a spec language to write guitar tablature and chord diagrams, mainly with a focus on being able to quickly type out diagrams or chords during a lesson (i.e., I am personally more focused on speed than expressiveness, though I'm interested in other options!).<p>I've found vextab [1] though it doesn't seem to be maintained anymore, and of course there are plenty of ASCII-art formats (GuitarPro et al) though these are really renderers, not markup (in other words, I want to _generate_ renders, not have to type them).<p>LilyPond [2] is neat, but of course much too verbose to jot down in semi-realtime.<p>I've started writing a language spec [3] and renderer [4], but surely someone else has had this idea before??<p>```catl
# chords:
X554X5
```<p>```catl
# tabs:    # ↓chord
0A 0D 5e 7B 3e+0D

<p>This is neat — I do think this is relevant to more than just the software engineering space. See also, healthcare and law (I wrote more at length here, not to derail this comment thread [1]). Our junior training on-ramps for a lot of knowledge-work fields are in some semblance of equilibrium, but it's an unstable one.<p>[1] <a href="https://blog.jordan.matelsky.com/AI-doctors-bum-me-out/" rel="nofollow">https://blog.jordan.matelsky.com/AI-doctors-bum-me-out/</a></p>

<p>Hi HN :) If you've ever played a game like scrabble or bananagrams you probably know the gratifying feeling of packing your letters into a dense little grid.<p>blueblocks gives you letters and assigns points for the _bounding box_ of your valid-words solution; smaller area is better!<p>every day has a "perfect" dense solution... NYT-style, mondays are easiest, sat-sundays are hardest!<p>feedback welcome! hope you enjoy :)</p>

<p>no worries, good to know this would be a useful feature! I'll add it to my backlog.<p><pre><code>    pip install 'git+https://github.com/j6k4m8/frof/'

and then<p><pre><code>    frof myfile.frof
</code></pre>
should work!<p>Was thinking about rewriting it in Go recently... :)</p>

<p>here they'll probably be executed simultaneously, since they both have zero dependencies and the machine can run multiple jobs at the same time. (can be disabled with `--max_jobs=1` or `-p=1`).<p>Here's another illustrative example:<p><pre><code>    A -> B
    B -> C
    Z -> C
</code></pre>
In this situation, frof will schedule `Z` to run in a parallel thread ASAP, so it will likely run alongside A... and if Z takes longer to run than A, Z will continue running when A stops and B starts. But C will wait for all other jobs to finish before it can schedule.</p>

<p>You write the file and ALL steps are run in topological order so that a job never runs until its dependencies have run. i.e., in a tool I'll have `build.frof` as a separate frof file than `download-dependencies.frof`, perhaps. (If your preference is that those belong in the same file I'd be down to have PRs that support that! Should be very easy, I'm happy to try implementing this if there's interest.)<p>So for a file with those contents called `mygraph.frof`, you can (after installing) run `frof mygraph.frof` to kick off the jobs in the current shell (inheriting env vars etc).<p>[edit] maybe a clarifying example here:

<p>I wrote frof [1] for exactly this purpose :)<p>Designed to be ultra-simple and with minimal "config-file acrobatics".<p>It looks like this [edit, formatting]:<p><pre><code>    write -> analyze
    build -> analyze

    write:     echo 1 2 3 > data.txt
    build:     compile_tool.sh > tool.sh

<p>That's a question more suited to a microbiologist or bacteriologist than to me, but my educated guess, at least in the electron microscopy case, is that you'll see the bacteria inside the depth of the slices, rather than sitting "atop" the slices. i.e., if you cut open an apple and find half a worm, the worm was in the apple. If you cut open an apple and then see a worm on top of the slice, it's possible it arrived post-cut.</p>

<p>Very hard to clean a blender!<p>More nitpickfully, one of the big things we care about is if the bacteria are living _harmlessly_ in the brain. i.e., site of microbes, and a lack of inflammation, will answer more than just "are there microbes around".</p>

<p>Microbes are CRAZY. They're everywhere. Thermal vent-friendly microbes. Space-friendly microbes. Vacuum-resilient, heat-resilient, acid-resilient. Microbe-free-environment-friendly microbes [1]. It seems hard to imagine that a blood-brain barrier could really keep the brain sterile.<p>We're lucky to live in a scientific era during which a "gut microbiome" is taken for granted (heck, even FDA-approved treatments depend on it! Google FMT, but don't click "images" from your work laptop), but it wasn't so long ago that we felt microbes were unlikely to live endogenously and harmlessly anywhere in the body.<p>There were also some hypotheses (untested, if memory serves) that COVID-19 influenced olfactory neurons through direct infection. Don't tell the blood-brain barrier, but if I were a bacterium, the nasal palate would be my ingress strategy. Or maybe the gums or gut — one of the cranial nerves, certainly.
[edit] I should clarify — covid is viral, not bacterial, but it does show that this is a potential entry vector.<p>The central nervous system is incredibly complicated, and our symbiotic relationship with microbes is extraordinary. I think it does a disservice to bacteria to suppose they DON'T get involved in an organ :)<p>[1] <a href="https://www.space.com/ryugu-asteroid-sample-earth-life-colonization" rel="nofollow">https://www.space.com/ryugu-asteroid-sample-earth-life-colon...</a></p>

<p>A few years ago my team mounted what I think was the largest-(to-date) scale search for this in electron microscopy brain tissue volumes [1].<p>I STRONGLY believe there is a substantial central nervous system microbiome, but (spoiler alert) no evidence found in that search :)<p>If you're excited about this work, the datasets are all freely available from BossDB [2] — well over a dozen petavoxels of it! I'd be so curious if models these days could pick up on something we missed!<p>[1]: <a href="https://www.biorxiv.org/content/10.1101/2022.07.12.499807v1" rel="nofollow">https://www.biorxiv.org/content/10.1101/2022.07.12.499807v1</a>

<p>raw data is O(petabytes) (single-digit); synapse-neuron graph will be probably order 100GB.

<p>The reMarkable company has been super adversarial to a lot of these tools, and the file standards and API have been moving goalposts for years. MOST of the tools on that Awesome list are defunct because the primary open source tools for getting data to the reMarkable cloud (rmapi and rmapy) are no longer maintained — the primary maintainers both cite reMarkable's moving target API as the final dealbreaker. SUPER sad.<p>I've been hoping to write my own now that the dust has settled, but it's definitely a MAJOR project yet to be done by the FOSS community.</p>
