Thanks! SadServers is great - love what Fernando built there. The main twist here is that the scenarios are built from real postmortems rather than generic server puzzles. The terraform one is modeled directly on the Claude Code incident from last week.
Thanks for trying it out! Just pushed a fix - there was a bug where the game engine wasn't starting properly after clicking GO. Should work now. Create a free account and give it another shot, would love to hear how you do.
If you followed the Claude Code terraform incident last week - Claude Code ran terraform destroy on production, took down 2.5 years of course submissions - you probably read Alexey's postmortem and the 500+ comment HN thread about it.
What struck me reading the postmortem wasn't the destruction itself. It was the decision chain: no remote state backend, deletion protection disabled, a Terraform archive from the old machine sitting there with full production state. Claude actually flagged the risk at multiple points. The human approved the destroy anyway.
I built a playable version of that session. You sit in a split-panel Claude Code interface - terminal on one side, AI agent on the other - and work through the recovery. The scenario uses the same kind of setup that caused the original disaster. It takes about 10-15 minutes.
This is part of YouBrokeProd, a browser-based incident response trainer I've been building. 10 scenarios total built from real postmortems - connection pool exhaustion, Kubernetes crashloops, DNS failures, SSL expiry, and others. Three are free including this one.
Stack: Next.js, Turso (SQLite at the edge), Supabase Auth. Each scenario is a state machine - you run commands, get realistic output back, form a hypothesis, and submit a diagnosis and fix. Scored on speed, accuracy, and efficiency.
The hardest part has been writing log output that's realistic enough to teach something but designed well enough to actually be solvable in 15 minutes. Curious what the SRE folks here think of the tradeoff.
This article never speaks to costs, as always with green energy, it's only green because the government funds it. How many years can a coal power plant last? How many years do these batteries last. What are the mineral inputs into these batteries? What are the inputs, costs and "renewable" properties of "green" energy? There are none. The batteries end up in toxic waste dumps. All the solar panels end up in the garage.
Stop chasing vanity and use common sense for utilities. How has this impacted their key metrics like reliability, what happens if there is ash in the air for a month and no solar can be provided? They took a proven, reliable production system and turned it into the latest JavaScript framework. Good luck.
Stop making up non-sense that have zero basis in reality.
The costs are fairly well captured in LCOE of these various sources of electricity. Questions like "How many year it lasts" is especially well captured.
> How many years do these batteries last.
For grid storage? Probably 1-3 decades. They'll have excellent battery management systems, chemistries that are optimized for longevity rather than energy density, they won't be fast charging/discharging, they'll probably never be discharged to 0%, mostly above 20% probably, which is also very gentle for batteries.
My EV battery is on its 8th year now with very little degradation. That's with primitive cooling (air cooling), older battery chemistry and fairly many charge/discharge cycles, including many deep discharges, since the EV battery is tiny (27kwH).
> The batteries end up in toxic waste dumps.
Completely false. Battery recycling is already happening at massive commercial scale, and reaching near 100% recycling. From consumer products like Apple iPhones to car and grid batteries. Car and grid batteries are particularly easy to recycle since you get huge bulk of identical cells.
Think about how insane it is to even consider this a disadvantage for batteries. How insanely many tonnes of coal will a coal power plant have burned in a decade? All that mining is gone forever. With battery materials mining, we'll eventually have enough materials for all the batteries we could ever need.
> All the solar panels end up in the garage.
Solar panels are a bit trickier, but that's also starting to ramp up at a commercial scale.
EU is already well ahead with regulations targeting recycling of these things. And given what's already demonstrated commercially, there's no reason to think 100% efficient recycling won't be the reality in a decade or so.
> what happens if there is ash in the air for a month and no solar can be provided?
Over a whole continent?
In France several of the supposedly reliable nuclear reactors went down at the same time a little while back. Huge amount of power went offline. They got by just fine with the help of their UK and German neighbors.
This. Stop thinking about work by not working. Stop any development on your own side projects - nothing dev related.
Take time. Life is not a grind. North American culture is really bad at promoting this. Fully disconnect is the only real way to recharge, change your perspective and future plans.
Lots more to come
