It is easy to compute on vectors. It is possible, but complicated and unintuitive (I have written code to do it in the past), to compute it on multivectors.

I'm arguing in favor of most of GA's language. I just keep finding that the wedge and inner product parts are fantastic, and the geometric product part isn't. And I think the reason people keep finding GA appealing is because they didn't have the wedge product before, so having that in their conceptual toolkit fixes a lot, while having the geometric product doesn't fix much on top of it. Anyway I've studied GA a lot and I still have basically no idea what 'AB' means when both are arbitrary-grade multivectors, and as far as I can tell most sources don't even try to explain it.
If you reversed the trajectory, the earth would still be falling towards the sun, but reversed orbit. i.e. orbiting counterclockwise instead of clockwise from a fixed observation point.

My thoughts exactly. A plain black box without any windows or lights is a refreshing change of pace. Wood grain just seems like kind of a joke on a PC.
You mean like the Serval? Or the Gazelle, if you want a slimmer version of the same thing? Both have upgradeable RAM, lots of non USB-C ports, and replaceable batteries. Both are quite handy systems.
To be perfectly clear, is this testing how antimatter and matter interact gravitationally, or is it testing how antimatter and antimatter interact gravitationally?

Negative gravitational mass is supposed to attract other negative gravitational mass and repulse positive gravitational mass. In your example time inversion makes both Sun and Earth negative mass so they still attract each other.

As others have said, it’s a question of what you want to get from learning.

Haskell primarily tries to answer the question, “What are static type systems capable of, and what new relationships can we achieve between code representation and code execution?”

Clojure primarily tries to answer the question, “How can we write programs more efficiently in the (relatively) short term?”

I do occasionally, but usually it's ViM over an SSH connection, and it's out of desperation.

As others have said, the keyboard, small screen, and other phone-specific issues prevent me from doing anything intense on my phone. I've tried several apps, and none have convinced me that programming on a phone isn't the worst idea ever.

However, I do quite a bit of development on my phone. For example:

- brain dump ideas
- resolve/update bugs in a bug tracker
- code reviews
- read documentation
- answer email
- IM

My phone is quite good at those things, it's just really bad at code. I'm still looking for a decent markdown editor for my blog, but other than that, I think I'm pretty happy where things are at in terms of mobile development. In fact, I've spent entire days working strictly from my phone.
Yes of course. I just mean, conceptually that is what is required. You can replace a bunch of the multiplications and additions by FMA instructions as well.

Tangential: Back in 2000 there was some debate about dropping quaternions in favor of a set of equivalent operations on plain matrices. https://www.gamedev.net/articles/programming/math-and-physic... The debate petered out when the proponents finished optimizing their implementation and found they had produced exactly the same code as the existing quaternion implementations. The only difference was the approach used to derive it.

The rear fan appears to be shared with the CPU fan. This is actually not a bad design in my opinion, many Dell OptiPlexes from around 2002-2009 were built with a similar design. By putting the fan farther from the grille, they can reduce the effects of noise from the blades passing by the stationary grill.

The fan appears to point inwards, which seems to make more sense for BTX Dells with the fan at the bottom than this with the fan on top.

The site mentions the power supplies are 80plus certified or something with (iirc) 90% efficiency or so.

Quality of the case wise it does look like quite some effort was put into it, given the top appears to be one piece and it certainly looks harder to manufacture than a standard PC case.

With that said, as much as it is nice, I think it's just more of a standard PC with a nice case.

It's beautiful to see that the logarithm of a rotation matrix is a skew-symmetric matrix. The skew-symmetric matrices correspond to angular velocity, which behave like vectors. You can add and interpolate as you expect. Rotation matrices multiply. Skew-symmetric matrices add. The logarithmic and exponential map moves between the two spaces.

Just letting you know that I think it's valuable to bring up matrices into this discussion, even if they do have problems in practice with rounding errors and efficiency.

Not sure I see the justification replacing postfix (which with simple configurations can be configured with just a few lines in a config file) with haraka written in javascript.

Unbound seems generally respected, is nice and simple, written cleanly, and does MUCH less than bind. However it has had at least one memory corruption bug that plagues most c/c++ applications of non-trivial complexity. It also does seem to hang and I ask around and other people have seen similar. It's no longer what I consider reliable enough to be installed on every client. It's scary that it hangs, because if it gets that wrong there's likely other issues as well.

I'm hopeful that SDNS is more reliable and secure. I just want a local caching resolver that understands DNSSEC.
The SQL with dot notation is nice, and something other databases have failed at doing with JSON. As for updates, it looks like _id is set automatically, and there's no UPDATE endpoint listed in the docs, so how is data mutated (by key)?

And my comment was more about the price, because at low volume of 10M records, any database system can already do fast queries. From the whitepaper, it looks like the indexing is intensive and that's where most of the cost is coming from, and explains the active/passive storage and tiered rocksdb-cloud setup.

Interesting use-case for prototyping but I don't see how it is cost-effective for higher-scale usages. Congrats on the launch though.

I will give you an example (from my recent work) where actually knowing what the components mean was useful.

I had to calculate misorientations between many pairs of orientations. If I treated quaternions as a whole, I would find their quotient and then get the angle. But since I know what the components mean, and I know I can get the misorientation angle from just the cosine (the scalar component), and I know that I can get this value from a simple dot product, I can easily save a few operations to calculate every misorientation. And since I have to calculate many of them, this change supposed a big speedup.

Black boxes are nice when learning or thinking at a high level, but if you frequently use a black box, knowing what is inside will probably become useful at some point.
On the one hand, interesting, but I don't think there's a worldwide conspiracy to prove global warming.

The most freedom is in IT, because you can go remote, there is no licensing (change markets at will), and starting your own venture is always an option with relatively low barriers to entry. Also, the norm is that you get paid, unlike - say - pure art type creatives. Try thinking outside of the traditional wageslave context and see if you can save on living expenses, tax or get extra holidays by configuring your life around longer term remote projects, etc. instead of doing the mortgage in a major city thing. It's worked out well for me, YMMV.

Even within the statistics community, there's a spectrum of quick-and-dirty vs fully rigorous. People with the ability and inclination to be fully rigorous often get treated as pedants and perfectionists (in the bad sense).

I often get that with business partners. "The data says <likely X, but with caveats/nuance/uncertainty/under certain assumptions we can't justify>" to which they respond "Can we just say X?" Or "can we get numbers on Y to support a presentation on Z?" when Y seems to support Z, but actually you can't draw that connection, so it's misleading.

Stuff like this happens because people treat extra rigor as pedantry and are comfortable making supporting assumptions that aren't supported by data. The people making fraudulent requests aren't aware that they're fraudulent (usually). In my experience, they just think they're being practical.
Yes, and I would recommend always assuming so on HN.

But if the argument is "let's replace quaternions in 3D engines!" then the question is really more "Okay, so do they outperform quaternions, then??" because if you're writing the 3D engine, the underlying code only matters insofar as that it has to do what it's supposed to do. You don't need to understand why it works, just that known operations will lead to known intended results. And if you're _using_ a 3D engine, you shouldn't even care. You just want rotation to work in the least amount of time, with the fewest function calls. What happens at the engine level, hidden by those functions, is entirely irrelevant.

And I don't see a case being made that demonstrates that for the purpose of a 3D engine, this actually "makes more sense". It's just a different way to compute the exact same results. If I'm writing a game, or simulation, or 3D visualisation, I literally don't are how the engine does what I tell it to do, as long as it does it.
I’m telling you that after a few years working with the geometric product a whole bunch, the wedge product really doesn’t cut it.

> I still have basically no idea what 'AB' means when both are arbitrary-grade multivectors

Any mathematical language (or any natural language) can express a bunch of nonsensical and useless things. What is the sine of the square root of the logarithm of the tangent of some polynomial applied to a scalar? Who knows?!

You can certainly make up nonsensical expressions using matrices, differential forms, etc.

In a concrete problem, sometimes you have to think a bit to figure out what the geometrical meaning is of a particular multivector, but if the problem came out of a physical situation, I haven’t yet found a case where I couldn’t explain it.

Your multivector might be an electromagnetic field. It might be a rotor. It might be a representation of a sphere in the conformal model, ...

To be clear, I don't think the wedge product is sufficient either; I just think it's the real reason most people end up finding GA to be appealing.

I think there's work to do to clean the whole space up. Particularly, the wedge product is a 'join' or 'union' operator (amusingly, it has the wrong symbol). The 'meet' operator is not widely known but should probably be equally prominent. I haven't figured out for myself where the other holes are yet.

I started programming professionally back in 1990 on IBM mainframes. I used to daydream about buying an old machine to run in the basement.
