- > You will have a switch at home (perhaps in your router) with more than two ports on it. At layer 1 or 2 how do you mediate your traffic, without CSMA? Take a single switch with n ports on it, where n>2. How do you mediate ethernet traffic without CSMA - its how the actual electrical signals are mediated?
CSMA/CD is specifically for a shared medium (shared collision domain in Ethernet terminology), putting a switch in it makes every port its own collision domain that are (in practice these days) always point-to-point. Especially for gigabit Ethernet, there was some info in the spec allowing for half-duplex operation with hubs but it was basically abandoned.
As others have said, different mechanisms are used to manage trying to send more data than a switch port can handle but not CSMA (because it's not doing any of it using Carrier Sense, and it's technically not Multiple Access on the individual segment, so CSMA isn't the mechanism being used).
> That's full duplex as opposed to half duplex.
No actually they're talking about something more complex, 100Mbps Ethernet had full duplex with separate transmit and receive pairs, but with 1000Base-T (and 10GBase-T etc.) the four pairs all simultaneously transmit and receive 250 Mbps (to add up to 1Gbps in each direction). Not that it's really relevant to the discussion but it is really cool and much more interesting than just being full duplex.
- New coal data is out just a few days ago [1], it's plateaued globally and expected to start to decline.
China's consumption this year was about the same as last, and looking to drop a bit, so likely old coal plants were being retired at about the same rate as newer ones were built, and that will start to go the other way (more retired than built).

- Grid forming inverters for providing virtual inertia are only going to get better and better, there's no reason that as those control systems improve why synthetic inertia won't be able to be basically identical to real spinning mass. In the meantime while that technology matures, synchronous condensers can provide grid inertia without needing nuclear or coal, we already have about four in Australia supporting our grid and will probably have another dozen or so built over the next decade or two.
- I have one machine that runs Windows (apart from one Windows 11 VM on my Mac laptop I use for work), all this nonsense has got me to install Fedora on a separate M2 drive on it, and I haven't booted up Windows in a few days now. Will be an interesting experiment, I've run it before but more for fun, but will try to go as full time on that computer as possible.
- I do agree, but there is still a valid logic behind what is shown because it's only using the pigments that there is direct evidence on the statue for - but to stop this confusion, maybe there should be three versions of each statue at these kind of exhibitions (assuming these are all replica castings and they're not re-painting the originals!) - a blank one to appreciate the unpainted form, the reconstruction of the base layer that only has the pigments found in the crevices (what this article is complaining about), and then an artists impression of what it probably looked like properly shaded (given that we have the evidence of painted statues as shown in the article).
Then you could still have the evidentially "pure" one, but also have a more likely rendering to reduce confusion.
- As a data point, I had mostly only seen what the author is complaining about in the past, with articles having more of the "you won't believe what ancient statues actually looked like" angle and implying that it's just our taste that changed.
So I definitely feel that I was misled by what I had read and seen about painted statues (though I was always a bit sceptical), even though everything I'd seen was from secondary sources (news sites etc.), and not articles or papers written by the reconstructioninsts themselves, so I don't blame them directly.
- As if nobody else ever did that (like Microsoft with DirectX, and almost every single games console)?
- It says in passing As the Metal backend is only supported on Apple Silicon devices, GPU and CPU share the same memory in the part talking about the differences between the Direct3D and Metal render pipelines.
Not sure why though, because Metal 3 is still supported on a bunch of Intel Macs...
- Streaming video from camera? In general the newer Mac Minis in general were fine already just because the M-series chips are very fast, but hopefully this should make it much more efficient
- Yes, I wonder if the rise of the Web Platform Tests have made browser behaviour much more consistent?
It happens so rarely, I don’t keep Chrome installed and have to download a new version of Ungoogled Chromium when I need to see if something only works in Chrome, which I can only remember doing about twice in the last year!
- Yeah, otherwise it’d weird the new CEO had such a precise idea of the amount of money it could bring in. It makes it sound like Mozilla definitely had either considered offers from advertisers or done the maths themselves to work out potential revenue.
And for the record, as a Firefox user, count me in with the others who would switch and just use Safari on my Mac if they went through with it!
- I have the same air to water heat pump HWS that Dave has - it's a split system so you can put the tank inside the basement and the heat pump outside. You just need to run two insulated water pipes between them and a temperature probe cable. There are of course systems where the heat pump is attached directly on top of the tank but lots are split. They should easily work at -10 °C so no issue having the heat pump outside.
- I'm sure it should help bring down the background levels of airborne pollutants, which should help as kind of a layered defence. But I expect it would be unlikely you could get it low enough to be in the same ballpark as a laminar hood, just because of the huge difference in air volume (the room is huge in comparison to the space the hood covers, so you need to filter way more, unless it was extremely well sealed in which case you'd just have to filter for long enough)
- Even as someone who is still a Firefox user - the browser now has about half the browser market share as Edge... Absolutely nobody needs to be paid to write these kind of comments!
Honestly the last 5-10 years has been a disaster for Firefox...
- Yes, Translate is the only one I want - and we already have that!
The worst is anything that tries to suggest stuff in text fields or puts buttons etc. to try and get you to "rewrite with AI" or any nonsense like that - makes me just want to burn anything like that to the ground.
- Longer term this shouldn’t be the case though - a fridge is just a heat pump, and an air-to-air or air-to-water heat pumps aren’t that much more complicated, nor should they be any less reliable.
It’s something that will become more of a commodity and eventually won’t be any more sign of wealth than owning a fridge.
I mean, we can see it already in air-to-air systems - I’ve had mini-splits supplied and installed here in Australia for something like 20% of the cost I’ve heard quoted for equally sized units in the US, for example - just because basically every electrician has a license to install them here because they are so incredibly common (for cooling even more than heating, but they can basically all so both here). Air-to-water I expect will be the same in cold climates - in 15 years basically any plumber will be able to do it and they’ll be far cheaper than today.
- They could very much force it on you, for new units at least - depending on what micro is on the boards, they could potentially very easy start shipping them with locked bootloaders (and disabled JTAG/SWD porrts) that would only run binaries that are signed by them.
They could potentially have their software load a unexpectedly re-flash existing units with a locked bootloader too, it would just be harder to keep the key secret (because the tool flashing the new bootloader on the first time would need to know it)
- > LLMs produce better writing than most people can and so when someone writes this eloquently, then most people will assume that it's being produced by LLM.
I really don’t think that is what most normal people assume… And while LLMs can definitely produce more grammatically accurate prose with probably a wider vocabulary than the average person, that doesn’t necessarily mean it’s good writing…
- As someone wanting to play around with it - is Vapor still the framework people recommend, or is Hummingbird the new hotness?
