Why then confuse users with the first dot? The second dot having a meaning makes it even more confusing. Just drop the first dot like Chrome and Firefox did.

Personally I use the word "MEOW" because a) it's easy to search for and spot in logs b) it will (hopefully) never be a legitimate string in the kind of things I work on c) fairly unlikely to cause offence (unless the customer is a dog)

Our testers (China and India) know that when they see KURWA or DUPA in logs that to send it straight to the polish site, we are considering adding a hook to check for those
ithinkso commented on Is running a more efficient way to travel than walking?   joehxblog.com/is-running-... · Posted by u/freediver

Another way to think about it--i.e. hoofed animals can only walk or sprint. Humans can jog, so as long as a human hunter can pick up the trail after the animal sprints out of sight, the jogging will eventually win out.

> i.e. hoofed animals can only walk or sprint

I did horse riding for a bit, that is not true. There is a lot of speed ranges you can choose from

This problem was treated with a bit more sophistication by Harvards Lieberman in „A story of the human body“ and the corresponding nature article [0] establishing persistence hunting as an ancestoral hunting technique of homo sapien. See figure 2b for the plot you were looking for. Running faster is less efficient but only slightly so and walking is a U-shaped curve like most mammal gaites.

It shows that in contrast to most animals, the efficiency curve of humans for running speeds is extremely flat, ie, we are about equally efficient at many different speeds, while the kind of game that we hunted was not.

The discrepancy allowed us to find a speed where we could exhaust the animal after 10-30km (as I understand) provided we were also excellent trackers.

I don't doubt the results but I cannot imagine how that can be true, I'm not fit but I've had many 20+hours hikes to the high mountain peaks but if I run to a bus stop when I'm late I'm tired beyond belief and I just cannot maintain running, have to stop

Well, I can write a definition that is both easier to understand and shorter than yours:

A tensor is a multi-dimensional array.

:)

ithinkso · a year ago
This is actually a harmful definition, both (1,1) and (0,2) tensors can be written as a matrix but they are very different. It's like calling vector an array but vectors require vector space and arrays are just arrays. It doesn't help that std::vector is very common in CS but 'pushing back' to a mathematical vector just doesn't make any sense
ithinkso commented on A worker from Berkeley's Urban Ore has opened a museum celebrating wingnuts   berkeleyside.org/2024/08/... · Posted by u/cainxinth

Whenever I look at something like this I'm always a bit astounded by the variety and styles of similar-purpose objects. I would love to see a deep dive on the evolution of these designs; it always seems like there is untold history lurking in these -- why not make the wings shorter or longer, thicker or thinner, curved vs bicurved vs straight, some hollow and some solid. Was it a question of the amount of material used, or how many could be manufactured in a batch, casting the threads vs tapping them, hand sized or sized to openings, maximizing torque or limiting torque to prevent stripping.

One of my most annoying memories of a museum was visiting the Cooper-Hewitt design museum where they had a wall with imprints of coffee cup lids, and I was thrilled at the idea of reading about all the tradeoffs involved -- how much cup strength is offloaded onto the lid to save costs on that end, etc. But it turned out that the wall was just an Art with no deeper meaning. And then they had a car that they said was well designed and my reaction was just -- how can you show me good design without showing me either bad design (all the ways it can go wrong) or the evolution of that design?

If anyone knows any museums that would scratch this itch, please give me recommendations!

ithinkso commented on Git-PR: patch requests over SSH   pr.pico.sh/... · Posted by u/steventhedev
quectophoton · a year ago
GitHub's greatest win has been convincing everyone that "pull request" means having a web interface for code review as well (conflating sharing code with reviewing it) and can only be done by creating accounts in websites; and that patch-based workflows can only be done through email.

They even convinced people that repository clones are called "forks" when they have a web interface but not when they're local.

I like that this project is trying to remove those misconceptions.

Of course if the contributor already has their own publicly available repository, then they can send you a pull request through HackerNews if they want.

    Hey I made some performance improvements, they are at https://example.com/git-pr.git on branch `improvements`.
That was a pull request. You can check out changes with `git pull https://example.com/git-pr.git improvements` and review them.

I've also done ad-hoc patches through Slack, using `git diff` and `git apply` but the idea is the same.

And yes I've also done stuff like this but with just `git push` instead of `git format-patch | ssh` (you want to look at pre-receive hook) messing around with friends on IRC. The problem is not how possible or easy it is, the problem is "just" gaining traction and having a good plan for moderating The Stuff People On Internet Will Upload.

See GitTorrent for another (unrelated) example of a good idea that never gained traction.

maybe there is a reason why github gained traction

ithinkso commented on How the continuum hypothesis could have been a fundamental axiom   jdh.hamkins.org/how-ch-co... · Posted by u/FillMaths
jerf · a year ago
That sort of argument makes me a nervous. One of my favorite mathematical quotes is a sort of related one about the Axiom of Choice, referenced and explained at https://math.stackexchange.com/a/787648: "The Axiom of Choice is obviously true, the well-ordering principle obviously false, and who can tell about Zorn's lemma?" That sounds like the "obviously false" branch of a similar debate about the continuum hypothesis.

Take your favorite hash function, and view it as inducing a directed graph on the set of its possible outputs. Finding a cycle is hard! (except, most hash functions map 0->0 for "nothing up my sleeves" appeal)

But also, it's ridiculously hard to answer simple questions about such graphs, such as listing its nodes.

ithinkso · 2 years ago
> Finding a cycle is hard!

I mean, it is easy in the size of the graph, you constructed implicitly an exponentially large graph, I don't think it's in the spirit of GP point where the hamiltonian cycle is exponentially (in the size of the graph) hard to find
