I don't know about your network, but for me that NAT device is sat on my network and so very much my problem :D
Mechanical strobe tuners work in Hz. Many "digital" electronic tuners are likely to be calibrated in Hz but display cents of deviation to the user.

One way I look at it when tuning two A4's to match 440, cents are always a fraction of where you are at the time. So a 439 vs 440 is by definition 1 Hz off and here that's a little less than 0.25%. Once you get the beat note below 1 per second (actually not often so easy) you're within 1/4 cent. At this range of pitch.

You can detect the cents by ear that way and when the deviations are minimized as optimally as you can get for the particular instrument mechanics, that one instrument is going to sound about as good as you can get.

When you get down to the bass notes like A1 at 55 Hz (conveniently annoying when accompanied by the hum from either 60 Hz American power transformers as well as overseas 50 Hz) a beat note of 1 per second means you are still about 2 cents off, or 8x the deviation you had at 440. IOW at the bass end you will have to aurally integrate the beat-note signal itself for about 8 times as long as you would for the 440 tuning fork, in order to make sure the beat is not occurring any more often than once per 8 seconds, for you to be as equally in tune in both of those octaves. A practical example would be a 440 tuning fork boldly serving as reference, and starting with a proper gage string a little flat at 435. Five beats per second difference is some serious flutter and anybody can turn the knob slightly and slowly until it's within 1 beat per second and in about 5 to 10 seconds of listening confirm it's pretty well identical, and you're within 1/4 cent.

But for ear tuning of bass like this you need to listen for about 40 to 80 seconds to reach equivalent confirmation.

You're so right though, no matter how you do the math, the physics don't change :)

I have not seen any electronic tuners having AI and whether or not they would beat a human, regardless, like regular tuners they would need to be given way more time to "integrate" the signal coming in from bass notes than most musicians expect. At least 30 to 60 seconds of clean detection. With no interference from other undampened notes, background noise, or stray vibrations for the input mic or contact tuners either. Even more challenging on notes that decay within a 30 to 60 second comparison period, where a good tuner can crumble even though it seems so miraculous when it's not bass.

Not to mention limited bass frequency response of transducers which tend to roll off bass like any other imperfect audio component.
Show HN: A Directory of Free, Open Source Alternatives to Popular Software
Hi guys,

I want to share the recent project i developed. I built AlternateOSS, a directory of free, open source alternatives and competitors to popular software.

Currently, i have listed 200+ tools so far and organized them carefully based on their main functionalities. I ranked them based on its category relevancy and feature completeness.

Some technical details & features:

- fully static site built with Astro

- View Transition API for smooth navigation

- Instant/static search with Astro static endpoints

If you have an open source project that can be an alternative to popular software, let me know. I will list it on AlternateOSS for free :)

Thanks, have a nice day!

Having been/am the other side this... they're probably relieved too. It can be counter-intuitive. Despite nature... there is potential for the desired outcome - with less pressure, honest [not forced] engagement.

Personally, my apprehension comes from within. It's nothing to do with anything 'outside'. My water level is different, that's all. Most reasonable people feel overbearing - it's on me, not them.

I love category theory, but I think there's a secret category of "high effort programming things" that programmers who have done them love to say that "Everyone should do x because it will make them a better programmer".

Here's the kind of things I'm thinking of:

- Learn category theory

- Build an interpretter/compiler

- Develop your own programming language

- Learn about and built distributed systems

- Learn to write code for the GPU

- Understand assembly code

- Learn about CPU architecture

I think, especially since it's the holiday season, maybe lets take a step back and just accept these things probably will make you a better programmer, but there are lots of them. If you do all of them, you'll maybe become a very good programmer, but you'll definitely become a very tired human being.

If you have an interest in the mathematical underpinnings behind some of the ideas in Haskell et al, you might love category theory, but if you just want to do effective functional programming effectively, you're fine just doing that

She mentioned it in a performance session that was recorded before I joined FB (I joined in 2013, I believe the talk was from 2011).

I completely agreed with her, but after watching the talk came to the conclusion that if she couldn't change it, then I certainly wouldn't.

More generally, younger people tend to be OK with everyone knowing everything, while as you get older you want to share with smaller circles to avoid conflict. Sheryl was quite a bit older than Mark and Chris at the time, which may have been the difference.
I remember discovering something like this in the first (?) Sim City. I must have been like 10 years old at the time. For some reason I had built so many police stations that the upkeep (was it 100 per station) was so high my monthly losses overflowed to profits.

Depends upon how much older you mean - at 65 in the U.S. you get Medicare which is not that bad.
I would treat them as totally different things. There is a Category of Sets, but a Set of Categories would be a bit harder to define. So axomatic set theory could be a specific case of category theory, I suppose. But you can probably do a Class of all categories. (A Class is sort of a set-theoretic way to get around Russel's paradox, incidentally, you usually use a Class to define categories, so...) Though that's actually quite an irrelevant point. It's a completely different language for describing mathematics. I think describing category theory as an alternative foundation for mathematics (you really mean topos theory here) is a bit of an exaggeration. it's technically true, but most mathematicians I know are using it as a powerful device to prove things in algebraic topology or geometry, etc.
There is a claim that a couple of researchers at the WiV got unwell with Covid a few days before anyone else. That would be an argument in favour of a lab leak. But I don't think it's established beyond doubt that this claim is true, and it's not a knockdown argument on its own.

The NSA might have access to Chinese top secret government records saying "oh shit, one of our experiments got out into the wild, cover it up!". Without seeing a smoking gun like this though, I remain on the pro-zoonotic side.

It’s good for writing credibly in a language you don’t speak well. This is useful for email-based processes where creativity and personality are not important.

Really? Wow. I had no idea, and I really tried to sound non-condescending.

I simply don't agree that redundant casts are something to be ignored, since they can be harmful and hide actual errors (the cast is a bit like `sudo make me a sandwich`, it makes the compiler do what you say which is not always a good idea).

I guess I believe that publicly posting code, and even writing a compiler for the language in question, kind of automatically marks you as interested in the language and open for ideas of usage and so on.

Category theory and set theory are deeply interconnected, as both are foundational areas of mathematics but with different focuses. Set theory studies collections of elements and their relationships, serving as the groundwork for much of mathematics, while category theory abstracts and generalizes these ideas to focus on structures and their relationships.

One key connection is that the category of sets, called "Set," is a fundamental example in category theory. Its objects are sets, and its morphisms are functions between them. This shows how set theory can be seen as a special case of category theory. At the same time, many categories studied in category theory have underlying set structures. For example, groups, rings, or vector spaces are often built on sets with additional structure.

Another connection lies in how category theory generalizes set-theoretic ideas. Concepts like products, coproducts, limits, and colimits in category theory extend the familiar notions of Cartesian products or unions in set theory. The Yoneda Lemma, a cornerstone of category theory, relies heavily on set-theoretic intuition, as it connects abstract categorical concepts to concrete representations in terms of sets.

Topoi, a concept in category theory, also bridge the two fields. A topos generalizes set theory by providing a categorical framework that behaves like the category of sets but with additional logical structure. This allows set-theoretic reasoning to be carried out in a more abstract setting. For instance, the category of sets itself is the prototypical example of a topos.

However, there are also differences. Set theory often grapples with "size" issues, such as distinguishing between sets and proper classes. In category theory, similar concerns arise, especially with large categories, like the category of all sets, which cannot itself be a set. Set-theoretic tools are often used to handle these size issues by defining notions like small and large categories.

And there’s a philosophical aspect. Set theory forms the traditional foundation of mathematics with its ZFC axioms, focusing on elements and collections. Category theory offers an alternative foundation by emphasizing relationships and structures, often referred to as "structural mathematics." These perspectives aren’t in opposition but rather complementary, with each offering tools to understand mathematics from different angles.

In essence, category theory builds on and extends set theory while also relying on it for foundational concepts. The two fields are tightly intertwined, with set theory providing a concrete framework and category theory offering an abstract, flexible way to study and generalize mathematical structures.

I've found this with React-Router/Remix too. I really like their Action/Fetcher model, it's a great way to simplify communication with the backend (or with client-side fetch requests). But as soon as you introduce a long-running task and you want some way to inform the user about progress or provide partial results, you're on your own.
Great to see your optimizations.

From the ACX post I linked in another comment, it seems that pre-pandemic the WiV was very much forthcoming and sent around notes of what viruses they'd collected and what they were doing to other countries' researchers:

> Are we sure they had neither [BANAL-52, which is one mutation away from COVID, and some other related virus]? Yes. Remember, WIV’s whole job was looking for new coronaviruses. They published lists of which ones they had found pretty regularly. They published their last list in mid-2019, just a few months before the pandemic. Although lab leak proponents claimed these lists showed weird discrepancies, this was just their inability to keep names consistent, and all the lists showed basically the same viruses (plus a few extra on the later ones, as they kept discovering more). The lists didn’t include BANAL-52 or any other suitable COVID relatives - only RATG-13, which isn’t close enough to work.

>

> Could they have been keeping their discovery of BANAL-52 secret? No. Pre-pandemic, there was nothing interesting about it; our understanding of virology wasn’t good enough to point this out as a potential pandemic candidate. WIV did its gain-of-function research openly and proudly (before the pandemic, gain-of-function wasn’t as unpopular as it is now) so it’s not like they wanted to keep it secret because they might gain-of-function it later. Their lists very clearly showed they had no virus they could create COVID from, and they had no reason to hide it if they did.

A lab leak doesn’t necessarily mean that it was created in a lab; it could also be a natural zoonotic virus that was actively being studied and accidentally infected one or more researchers.

Looking at the ISO 9899:2018 spec, a few sections appear to be relevant.

This one I wasn't familiar with, and I believe it absolves the comment I initially replied to in this thread.

> 6.5.2.3.6 states:

> One special guarantee is made in order to simplify the use of unions: if a union contains several
structures that share a common initial sequence (see below), and if the union object currently contains
one of these structures, it is permitted to inspect the common initial part of any of them anywhere
that a declaration of the completed type of the union is visible

Outside of that special case, the general semantics of unions are specified as follows. I think that means you are right?

> When a value is stored in a member of an object of union type, the bytes of the object representation
that do not correspond to that member but do correspond to other members take unspecified values

Gratitude is nice but the poems that do change governments and people's lives for the better can't only do gratitude. Anger is needed too. Accountability is important.

Some people treat the oppressive government as weather. Something you don't have any control over and therefore - no responsibility for. Others treat it as their responsibility. And these people are NOT grateful, when injustice is done in their names.
