We don't use CO2 to make cement, we use limestone, and CO2 is the byproduct of heating the limestone to make reactive calcium.

Not at any scale that counts. There are a whole bunch of companies _trying_ to make zero carbon cement, but it's all very early stuff. The lifetime of a cement plant is 30-50 years…

Yes! Likewise for grinding: offload excess power to industrial plants so they can grind rocks when it's windy. If you look at the problem in the right way, a silo full of ground ro…

I work on decarbonising cement production, and the cement producers are betting _heavily_ on carbon capture as their "get out of jail free card". I think they're likely wrong, but …

Concrete absorbs co2 while curing. It's the calcination process, where we heat limestone up until the co2 burns off, that has unavoidable emissions. Since this concrete is recycled…

The emissions trend is slowing. We have the technology we need in order to change course, we're just not deploying it fast enough. The worst projections, at least, are off the tabl…

If you're new to programming, steer clear of design patterns. If you're a working python programmer who's curious about how other ecosystems use design patterns, try https://www.co…

I'm starting a new job doing exactly these things in order to reduce the carbon intensiveness of heavy industry, specifically cement production. I'm hyped because I think the techn…

And they're free to continue their speech elsewhere. Cloudflare and Voxility are within their rights to refuse service to a client on the basis that the client is persistently asso…

The difference is that every single one of your counterexamples is something that society depends on. Nobody depends on 8chan. 8chan is not comparable to "air". This point is so in…

Yes. Reasonable people "exclude the middle ground" on support for domestic terrorism.

Your comments here aren't helping. The clear implication is that Dr Bouman is receiving "undue credit" in order to push a "feminist narrative". If that's your honest reading of eve…

I had issues with depression when I was younger. Self-harm, severe depression, suicide attempts, the whole gamut. Wasn't hospitalised, but that was the next step. Looking back on i…

We use nginx-vts ( https://github.com/vozlt/nginx-module-vts ) to get metrics out of our nginx servers, and then we send them over to our Riemann stack with a Collectd module: http…

I'm running Arch on a Dell M3800, most of my colleagues are running various Ubuntu flavours on the same hardware. Works well, up to and including the touchscreen. Battery life is p…

Heuristics. Really complex heuristics that defy simple codification: the feeling that a particular group of stones just isn't quite safe yet, the feeling that there is weakness in …

The same arguments were made about object orientation: I've never needed it, it's useless baggage with no real world benefits, it sounds great in theory but has no practical use...…

It's really not, I'm sorry. State is carried by the client, the client traverses links to find out what it can do, the responses are described by a published content type, and the …

I don't see much use for this project over, say, Compose, but I use dockerised services for development in my current day-job. I'm an architect helping to move a a cluster of monol…

So much fear and loathing in this thread, which puzzles me. Anyone who sets out to write a hypermedia API in JSON is going to end up with a structure not dissimilar to this one. If…

I get the sense that you're concerned you won't be able to keep up with technology trends. This is a non-issue. 95% of what you read on Hacker News is essentially froth, the epheme…
