It would be neat if it there were an option which added distance and elevation gain, but minimized the grade.
For example, a route from SOMA to Nob Hill can be made flatter by approaching from either the east or west. Technically the "flattest" as measured by elevation gain between the two is straight up Taylor from Market, but it's much nicer to bike to the top of Nob Hill by going out of the way (e.g. Polk → California, Embarcadero → Broadway, etc.)
I suspect that this would result in absurdly long routes. Imagine trying to go up a mountain while minimizing grade... you'd end up zig-zagging back and forth endlessly.
Isn’t that exactly how you build a trail up a mountainside? They are usually a series of switchbacks.
Most people on most bikes can only take so much grade before climbing becomes impossible. A maximum grade setting would be very helpful for that exact reason.
Oh, yeah, I interpreted the parent comment as "minimize the grade" but if it's instead "keep grade below threshold" (for reasonable thresholds) that would make more sense.
I feel like even if the distances are equal, it's faster to walk a bike up a steep grade and bike the rest flat than it is to bike up a moderate grade the whole way. This topic has probably been discussed somewhere else.
People can generally only output their max power for short durations. The output level they can sustain is generally much lower. I bet you could try to model higher limits for short distances, but what those should be could vary greatly depending on personal fitness.
I think that too favors walking the bike up the incline. Anyone able-bodied should be able to do it, some faster than others, but biking up an SF incline is more hit or miss, especially when considering different bikes.
My reasoning for the bike-hike being faster is that legs are designed for it. Legs are only inefficient on flatter ground because you have no equivalent of high gear (like extendible legs), so all that torque is going to waste.
That's some of it too, but in a way legs aren't all that different from wheels in how they work. Most of it is the gearing. Like there's a gear on every mountain bike that will make your feet go down at the same intervals as walking. That sucks on flat terrain. Legs are also not perfectly designed to push pedals, especially for people who don't bike often.
Unless you are on foot (and even then) the route needs to follow existing roads, you can only zig zag as much as existing roads do it not endlessly.
And almost any practical routing system will have a mechanism for tradeoffs of different aspects. Often there is a distance/time tradeoff which directly relates to speed on corresponding segments. But the tradeoff can also be in the form of "on average x seconds spent waiting green light in each intersection or time to stop before railroad crossing. So there is no reason for a system optimizing grade to completely ignore all other factors, it's just a question of weights and curves of each of them.
Like the ascent to Mt. Hamilton (southern Bay Area). You can see the peak for like an hour but so much twisting back and forth, going mostly perpendicular to the max gradient. It is an old road and hence graded for mules to carry up telescopes.
your example (from market & taylor to the top of nob hill) is a nice illustration: (1) straight up taylor is 229 ft of climbing at 25%, (2) via polk and california it's 251 ft at 13%.
as you probably noticed, we only look at the total elevation gain, so taylor "wins"... but I see the argument for preferring an extra 20ft of a more gradual climb.
In their case, it's motivated by a desire to keep copyrighted code out of the SQLite implementation, but I'm sure it has a nice benefit of making it so that an extremely widely used project doesn't get drive by, low effort code review requests while still allowing the community to engage.
Asking that "random people on the internet" don't sent code is not altogether a novel, post-AI idea.
> Additionally, some repos can be configured to automatically merge PRs when all requirements are met, one of which might be your approval.
If anyone at GitHub is reading this, I’d love a fourth checkbox in the “leave a review” modal that is “Approve but disable auto merge” (alongside Comment/Approve/Request changes)! Even just surfacing “this PR has auto merge enabled” near the Approve button would be great.
This feels like a suboptimal solution to me because I personally like to keep comments in "unresolved" state so that they remain visible and other folks can weigh in on them if they want, but in a way that doesn't block the PR. Basically I wish that GitHub would either separate the "collapsed" and "resolved" concepts, or add this "approve without merging" button.
I want the same mode, but on iOS! Imagine carrying nothing but the phone in your pocket, sitting down at your desk, plugging your phone into the monitor, which has your keyboard and mouse docked, and you have a full development environment.
Partially there on Android Pixels with "Linux Terminal". With the rumored convergence of ChromeOS and Android, it should be possible to have a desktop ChromeOS pKVM VM with accelerated vGPU graphics on Android mobile devices that have enough RAM.
Even in Vim, the editing experience falls over when making markdown tables that have non-trivial content in their cells (multiple paragraphs, a code block, etc.). I recently learned that reStructuredText supports something called "list tables":
Where a table is specified as a depth-2 list and then post processed into a table. Lists support the full range of block elements already: you can have multiple paragraphs, code blocks, more lists, etc. inside a list item.
This syntax inspired the author of Markdoc[1] (who came from an rST background) to support tables using `<hr>`-separated lists[2] instead of nested lists (to provide more visual separation between rows).
I have found various implementations of list table filters for Pandoc markdown[3][4], but have never gotten around to using any of them (and I've tossed around ideas of implementing my own).
reStructuredText & AsciiDoc are so, so much better than Markdown since they have rich feature sets to actually build documentation, blogging, & so on. It’s a massive shame everyone would prefer _yet another Markdown fork_ like the OP.
Damn, there really are no original ideas anymore. I have been working on essentially the exact thing that Spektrafilm is doing. I'll check that out to see how I can improve my setup.
Still the only thing I miss about the Firefox right-click context menu coming from Chrome is that Firefox doesn't have a "Look up '<selection>'" in the menu on macOS, to look up in the macOS dictionary, for looking up words I don't know.
A more complicated version of this problem exists in TypeScript and Ruby, where there are only arrays. Python’s case is considerably simpler by also having tuples, whose length is fixed at the time of assignment.
In Python, `x = []` should always have a `list[…]` type inferred. In TypeScript and Ruby, the inferred type needs to account for the fact that `x` is valid to pass to a function which takes the empty tuple (empty array literal type) as well as a function that takes an array. So the Python strategy #1 in the article of defaulting to `list[Any]` does not work because it rejects passing `[]` to a function declared as taking `[]`.
For example, a route from SOMA to Nob Hill can be made flatter by approaching from either the east or west.
