From the project README. That to me, is an emulator.

Companies that pay people to hit enter instead of using auto-approve/bypass are going to lose to companies that pay people to think and produce results, regardless of how much time they spend in front of the screen or how many prompts they input.

IMO LLMs are the best thing to happen to coding in my ~15 years of being in the game.

I wager they have probably added on another 5-10 years to my engineering career as I was contemplating getting out before they showed up.

Have also been convincing some friends that have "gone woods" over the years to put the woodworking tools down for a day or two and give them a go. So far so good, a few folks have found the spark again and it's been awesome to see them make digital things again too.

Rails niche was fast setup/low starting out costs and relatively constrained/medium maintenance costs. To get this you traded performance and type system. The latter usually resulted in increased maintenance costs as test suites ballooned to compensate.

These days fast setup is simply a product of AI, every ecosystem now offers fast setup. Maintenance costs are now about how token efficient it is to find and fix problems. Test suites are going to be huge everywhere now but there is some chance languages that require less to accomplish more will win on token efficiency and be favored.

Humans aren't the dominant factor in programming language design or selection anymore, that is a fact at this point it just hasn't sunk in for everyone yet.

We are only ~6mo in to agents being good enough to write code. A year from now our profession will be entirely changed. Agents will get better (how much? don't know) but importantly they will definitely get cheaper and access will be broader. Which is really the point DHH was trying to make.

Access and economics are finally going to do what no-code failed to do, which is democratise software. Maybe not to the point that everyone writes code or even that shit programmers are good, but it will enable shit programmers to write Rust which was literally impossible 6mo ago and they will have better programs as a result.

Which is the other thing he touched on. Good programmers are going to excel here and great programmers are going to dominate. I'm already seeing the 10x programmers hit 100x and 1000x with more access doesn't seem out of sight. It's also restoring the will to create in a lot of people that lost the passion for the mechanical part of programming, unlocking the experience and skill of these people that were otherwise considering cashing in the bag is huge.

So yes. Rails is done but what is coming next is way more exciting. I'm with DHH here, be glad it happened but get moving on where things are going to be instead of clinging to the past.

Logic is usually rated to run up to 110*C but DRAM processes aren't rated for such high temperatures and perform worse the hotter they get in terms of retention etc.

There are also some novel approaches here in terms of banking choices and impact on refresh times as a result.

The end result that matters for normies is that if this process is turns out to be a success it will challenge and perhaps beat HBM.

That in turn matters because this process is vastly more wafer efficient than HBM for the same bandwidth. Which in theory would ease supply on DRAM wafers.

Except it is also more efficient in terms of energy/bit/s so very likely what will happen is chips will still target the same TDP and just use even more of this rather than consume less wafers because that is just how AI is today.

Disclaimer: I work for a competing company that also makes AI inference chips.

I averaged around 18mo to either a promotion or a move in my 20s, mostly off the back of working harder (to get the promotions/comp increases) and working smarter (to work out when they aren't coming and jumping somewhere else).

If this makes sense for someone has a lot more to do with their ambition/desire and ability to work the system than anything else. It also helps a ton if you are also legitimately very good at what you do. Then it's pretty easy because you are just demanding you are paid commensurate with impact.

Simply doing overtime and having hustle doesn't cut it though, you actually need to be able to leverage it into career progress or it's just wasted life.

This is mostly an America problem right now because that is where everyone wants to build the DCs and it's the market with the most stagnant generation: https://en.macromicro.me/collections/26367/electricity/14247...

Back when I was running my own startup I moved to Mascot, Sydney to be near Equinix SY3 that was being built which we had bought a decent chunk of committed capacity in. Mascot was originally an industrial area but was gentrified a lot over the last 20ish years but the datacenters, meat packers etc are all still there. It really adds to the charm of the place in a lot of ways, warehouses/factories that have been converted to cafes and breweries. Which is to say I don't think living near a DC is bad at all, they aren't very loud and they just look like big warehouses with lots of lights, cameras and no windows. Oh and security dudes.

Anyways. Yes. The hardware I am working at $DAY_JOB is all direct liquid cooled. The coolant that actually cools the hardware is closed loop, it's not expended. Which means you don't actually use any of it and it's considered good for the entire life of the hardware.

I normally don't directly talk about $DAY_JOB things because there are pretty strict rules so I can only use publically referenced sources but you can read a little bit about the coolant we use in this article [1].

The facility loop though is usually what people are worried about. A lot of datacentres that were built in low humidity environments use evaporative cooling which does indeed use a ton of water. However most data centers in more humid environments don't and either use loops that recycle the water but dump the heat (i.e rivers/lakes) or use closed loop systems with radiators etc. It's worth mentioning though that evaporative cooling is extremely power efficient vs most closed loop solutions so there is a tradeoff here. I don't think Google could achieve their fleetwide PUE (Power Usage Efficiency, basically measurement of how much power goes to things in a DC that isn't a computer) numbers without relying on it heavily.

Given the difficulties getting DCs approved in much of the world right now and the backlog on generation capacity (i.e power) almost all modern DCs are being built to use as little water as possible.

To give you an idea I think evaporative cooling of the type you would find in a state of the art Google DC with a PUE of ~1.1ish might use 1-1.1L of water for every kWh of actual equipment load (this is a back of the napkin estimate, don't hold me to it).

Conversely true closed loop will use approximately zero.

So yeah, evaporative is a big waster of water especially at GW scale.

No datacenters isn't about AI or even resources like water or power, it's mostly about real-estate and housing prices as usual.

If we listened to NIMBYs we would have no new infrastructure, no high density housing, no public transport.... oh wait.

I work on very low level stuff (think RTL/FPGA, firmware, software where optimising for nanoseconds is just normal).

For me Sol is the only cost effective model available. Fable 5.1 is indeed good and vastly better than original Fable (which refused to work on most of my stuff for 'safety' reasons).

It's very good at this sort of low level stuff to the point that I really can't understand/relate to people having a good time with Opus (which comparatively performs extremely poorly on my particular workload).

I also just don't like how lazy Anthropic models are. They will do 10% of what is asked and then summarily declare victory.

Sol on the other hand is more like "one of us", slight touch of the 'tism, extremely pedantic, will go to the edge of the known universe if that is what it takes to prove/fix/build what you asked for or run out out of credits trying.

It's a personal and workload dependent thing. For me right now Sol for 99% of stuff because Fable 5.1 still burns through $5k in credits a day.

> 5 pilots were in the cockpit of this flight. In addition to the normal crew of pilot-in-command and co-pilot, there was an experienced relief pilot and two additional check captains; one was being trained as a check captain (CC) and the supervising CC, who was training the CC.

Captain Richard Champion de Crespigny had 35 years of flying experience at the time of the incident.

That is an insane amount of flight experience in the cockpit and all of the reports state this was a very significant factor. i.e by allowing distribution of the task load, plenty of time for one of the pilots to compute landing calculations manually etc.

THe A380 is a flying tank no doubt, but it wasn't the sole factor here - I think most people would agree this one was a shared victory.

However if everyone else stopped using AI we would be broke, so please don't do that.

Doubly so if they are mediocre to start with and triple so if they bring with them their legion of yes-men.

I was on a proper employment visa 8 years, never needed to leave the country.

Seeing this at $DAY_JOB already. I suspect soon at $DAY_JOB the only 2 low level languages approved for greenfield will be Rust and Ada/SPARK.
