> Are there workloads where the AMD suffers due to its l3 design?

Databases, particularly any database which benefits from more than 16MB of L3 cache.

> On my 3900x L3 latency is 10.4ns when local.

And L3 latency is >100ns when off-die. Remember, to keep memory cohesive, only one L3 cache can "own" data. You gotta wait for the "other core" to give up the data before you can load it into YOUR L3 cache and start writing to it.

Its clear that AMD has a very good cache-coherence system to mitigate the problem (aka: Infinity Fabric), but you can't get around the fundamental fact that a core only really has 16MB of L3 cache.

Intel systems can have all of its L3 cache work on all of its cores, which greatly benefits database applications.

---------

AMD Zen (and Zen2) is designed for cloud-servers, where those "independent" bits of L3 cache are not really a big problem. Intel Xeon are designed for big servers which need to scale up.

With that being said, cloud-server VMs are the dominant architecture today, so AMD really did innovate here. But it doesn't change the fact that their systems have the "split L3" problem which affects databases and some other applications.

Unfortunately these lower leather prices certainly don't seem to have affected the price of premium, handmade leather goods.

I suspect (but cannot prove) that in the case of premium, handmade leather goods, the majority of the cost (probably a really big majority) is the time of the people hand-making it, which is unaffected by the drop of the cost in the leather.

Esperanto uses a similar system:

5 is kvin and 10 is dek so 50 is kvindek. If you know how to count to 10, you know how to count to 99.

100 is cent, so 500 is kvincent. 505 is kvincent kvin and 555 is kvincent kvindek kvin. Alright, now you know how to count to 999.

A "number to Esperanto" is a great exercise to code and Esperanto is a lovely language to learn. Try it!

We use platforms and layers that are at the level of branches and leaves on trees, supported by abstracted away structures hiding complexity that make them simpler to use as a platform higher up the tree (or down).

A researching traveler can go down the branch, to the trunk with lots of time rings and layers, and then further down there are many root systems and rabbit holes.

All sorts of functionality is abstracted away in layers down there, all the way to machine code and binary and everything before the epoch 1/1/1970. Epic programming and technology pioneer legends created it, they took complexity and made a simple platform layer for others to build on.

I left school in '93. Throughout my school career I was the only person I knew who was diagnosed with anything like that. I only got diagnosed after talking to a physio who was treating my brother. Once that happened I started being treated a lot differently, and got to use a nifty little Amstrad[1] laptop to work on. Pity it happened so late, I might have enjoyed school more.

I worked for a regional isp where almost the entire metro network was a single layer 2 network up to the point of presences. We regularly (as in at least once a week) had spanning tree loops and broadcast storms that took down the entire city.
It's a cycle we've seen before. Just enjoy the ride and take the benefit while it's there. Hopefully things are different this time, but many of us remember when AMD beat Intel to 1GHz and also the major win that was amd64 and the overclocking madness that came with Barton. This industry is cyclical in nature. I am an AMD fanboi from the K6-2 days, so I am a restrained optimist about the current wins.
> How am I not paying for the same thing twice?

In some ways you are. This is the same pain the music industry went through when they went digital. People had purchased records, 8-tracks, tapes, and finally CDs often of the same music and often multiple times because those physical items wore out. Now I can buy a song once and it is effectively mine forever. Book publishers see what happened to the music industry and are fighting every way they can. A lot of times those fights do not make sense, but the industry has decided to fight everything.
I seems to me that you and hyperpallium agree.

I still hold that

1.) That book is still one of the most relevant books I've seen lately (which might be scaring, I haven't made up my mind yet)

2.) While he might not have (or at least not include) data, he argues hos case well, and while I wouldn't bet money on experiments to follow his smooth curve I would be willing to bet (a small amount of) money that for non-trivial software his ideas would still result in better estimates than one that accepts "man-months" as a unit of progress.

And for those that haven't read the book yet it might be worth noting that while some people might find the book quotable more or less from cover to cover there is also a number of observations to be made that takes a full reading to realize. Here is one I'd like to point out:

Some quotes from the book might leave one thinking that he says programming cannot be scaled. I'd say the opposite is true, he just argues that it must be done in a thoughtful way instead of by mindlessly adding people to the project.

That quote is not exactly correct, there are plenty of evolution equations which are not time-reversible beginning with the linear heat equation. If you look at the solution given by convolution (usually taught in first PDE course) you see that this equation has infinite speed of propagation. Any parabolic/dissipative equation is not time-reversible (which is analogous to addition not being reversible... dissipation involves an averaging process).

Elsewhere the author says "all fundamental evolution equations in physics are time-reversible." By fundamental I'm assuming she means: Maxwell's equations, Einstein's field equations and the Schrodinger equation.

It's an interesting question. Arguably, any model trained on copyrighted works could be said to be a derivative of those works, as the model is composed entirely of the copyrighted works run through a deterministic computational process.

But on the other hand, we certainly wouldn't apply that same standard to a human who "learned" from copyrighted works, so where do we draw the line?

Maybe the feedback here is to make that clearer, without knowing much that sounds like a huge selling point compared to your competition, so you should pull attention to it. This is what your website says right now:

How about clarifying it to something like:

> 7 day free trial: after that unlimited users costs $49 per month. That's for your entire team!

Something that brings home the point of how much of a difference this is compared to the "per-agent" pricing that's pretty much standard.

I'll leave it to others to decide how viable this pricing is :-)

The time to review a diff is proportional to how much work it needs. Code reviews that are within the normal bounds of “needs mentorship” don’t cost that much. Productivity is noticeably down across the board during intern season, though.

It’s more than a full time job to push back on all of a bad hire’s output, and people are accountable for their own projects as well. Things inevitably get to “fuck it, good enough.”

Well, it's selling a speech-to-text service, that the user applies to speech they own a license to. Why should the legal interpretation differ, just because of where the conversion happens? It could be done locally, or remotely, or locally but charge the user per-word translated. Looks like an implementation detail to me (and again, I think there's precedent backing me up in this view, but I can't find it, sorry).
One theory that the paper has (in the last page) is that the reason for the construction was a consequence of Solidity only having support for 256 bit integer arithmetic. So as a workaround (to avoid writing a library that does larger bit operations) they came up with a scheme using three 256-bit keys instead.

Obviously using Curve25519 would've made it possible to have a secure setup under the "256 bit arithmetic only" constraints, but I have a feeling (assuming this theory is correct) that someone who thinks that three 256-bit keys are significantly more secure than one 256-bit key probably would've messed that up too.

> Similar would be whether YouTube can automatically add subtitles to videos without explicit permission from the video uploader.

That's a very good one.

My personal opinion is Youtube should not be able to add captions without your consent because suddenly this changes everything.

What if one day Youtube decides to add a transcript feature where they can turn a video into a decently formatted blog post. Now imagine if you had your own website where you used to make a blog post about your video manually and then uploaded your video to Youtube with a link back to your site.

A move like that could remove a lot of traffic to your site because chances are Youtube would outrank your personal site by a lot in search results and would also give people less of a reason to ever click back to your site.

But this is really similar to audio books vs text. They are both independent mediums and having access to 1 shouldn't guarantee free access to the other. It should be up to the discretion of the content creator (or publisher if they are not self published).

At least in the UK, any new electrical domestic installation must be protected by RCDs (which protect human life from electrocution in the event of ground fault by disconnecting phase quickly enough) and not just MCBs or fuses (which are to reduce the risk of electrical fire from occurring in the wiring due to too much current being carried).

I think this has been the rule now for c15 years so depending on your installation it might have been that that saved you.

So if a firm with 50,000 employees signs up, you'll charge them $49?

You should reconsider this pricing model because a client of any considerable size is both able and willing to pay for a product that is financially stable. $49 won't keep the lights on, and the fear of investing time and data into a system that won't survive financially due to poor pricing might scare off some potential customers.
Electricity accidents are very rare, generally not fatal, and the victims are mostly electricians. In Germany there are around 30-40 fatalities each year.

In the US there are about 140 fatalities per year, so per-capita fatalities are very much on the same level.

I see no reason this couldn't be applied to English. "-nz(e)", etc. is akin to "-teen", and beyond that it should be exactly the same, with septante/seventy, huitante/eighty, and nonante/ninety being the popular English versions (unlike e.g. Metropolitan French).

Unsupervised Text Summarization via Mixed Model Back-Translation
I’ve heard this idea a lot and it always strikes me as one of those things that’s technically true but wildly off base. I get that the equations are mathematically reversible. Presumably we’re more interested in the world than we are the math though, and in real life almost nothing can be worked backwards. There’s a lamp on the dresser for example. How did it get there? Go ahead and run the kinematics in reverse and tell me which of the infinite solutions is the truth.

> Is it the the larger random cache writes that are causing the additional latency?

Think of the MESI model.

If Core#0 controls memory location #500 (Exclusive state), and then Core#32 wants to write to memory location #500 (also requires Exclusive state), how do you coordinate this?

The steps are as follows:

#1: Core#0 flushes the write buffer, L1 cache, and L2 cache so that the L3 cache & memory location #500 is fully updated.

#2: Memory location #500 is pushed out from Core#0 L3 cache and pushed into Core#32 L3 cache. (Core#0 sets Location#500 to "Invalid", which allows Core#32 to set Location#500 to Exclusive).

#3: Core#32 L3 cache then transfers the data to L2, L1, and finally is able to be read by core#32.

--------

EDIT: Step #1 is missing when you read from DDR4 RAM. So DDR4 RAM reads under the Zen and Zen2 architecture are faster than remote L3 reads. An interesting quirk for sure.

In practice, Zen / Zen2's quirk doesn't seem to be a big deal for a large number of workloads (especially cloud servers / VMs). Databases are the only major workload I'm aware of where this really becomes a huge issue.
Hell, pre-screening as a concept was taught to me in a biology class 10+ years ago with one example being (some) Jewish communities implementing genetic counseling as a pre-screen before marriage to avoid unwell offspring, e.g. Tay-Sachs. Organizations[0] exist for this purpose already.

The ethics of this as a situation was taught by watching and discussing Gattaca, a movie from 1997.

Certainly not a new idea nor concern. It is a reality, though not quite widespread. Perhaps we will open new societal cans of worm through mass-market, rapid screening. As I write this, somewhat reminds me of the internet.

Even staying within materialism, it isn't clear that 'everything is physics'. For example, our computers operate according to the laws of physics, but the physical laws tell us nothing about how they operate. To understand how computers operate, we need to know a lot of extra information besides the physical laws. In other words, physical laws tell us nothing about physical conditions. This is why there are many other scientific disciplines besides physics. So, since this notion of 'everything is physics' doesn't even work within materialism, it is hard to see why it would exclude immaterial entities.

And as you point out, the notion that Darwinian mechanisms can account for evolution of complexity and diversity is pure speculation. Which is why modern evolution theory does not use Darwin's theories. It uses mechanisms that we can see operating in the lab and in bioinformatics, such as bacterial horizontal gene transfer and empirically calculated substitution matrices. And the further that bioinformatic algorithms diverge from Darwin's ideas, the better they perform.
One of the most interesting articles on warfare that I've read this year.
Audiobooks add on top of the original book; but I would argue that you could train a human being with a set of deterministic rules that they can use to transform an audio-book into the exact text of the text-book that was published, with 100% fidelity, 100% of the time. Which is to say, an audiobook is a lossless embedding of the original text-book. If you’re buying the audiobook, you’re already buying the text-book; it’s in there!

Another way to look at it: if you own a music video, do you have a license for the song that the music video is a music video of? I would argue you do—you have to have that license, to be able to have a license for the MV, just like you have to own licenses to all the tracks on an album, to be able to claim to have a license for listening to the album.

And, as such, it really wouldn’t make sense to attempt to sell licenses to consumption of MVs, that don’t implicitly include licenses to consumption of the audio tracks within said MVs. (Has anyone ever argued that people don’t have a right to use youtube-dl to extract the audio track from MVs publicly-posted by their rights-owners? I assume, if they did, this argument went about as well as arguing you can’t record music off the radio...)

This is the equivalence being offered here: a text book is to an audiobook as the audio track of a music video is to the MV itself: a component. In the case of a text book, it’s not one that’s literally there in bits; but since it can be extracted with 100% fidelity, the information that component is made up of is clearly there, in the thing you bought. It’s no different than if an audio track was embedded in your video but was reversed or something.
