Same class of bug hits the JVM, Go (GOMEMLIMIT) and Python with big allocators. Any runtime that autotunes off host memory needs telling when it's inside a cgroup.

'Both versions are equally present and equally plausible' is the clearest description of this I've read. Moved my plan into a file this morning.

Split the two things into two turns and two commits. Turn one: fix. Commit. Turn two: "now, if you think this file needs refactoring, propose it." Half the time the proposal is good and I take it, as its own commit with its own review.

The problem isn't that it refactors, it's that the fix and the refactor arrive in one diff and you can't approve one without the other. Git solves that, not prompting.

That's a legitimate mode and I use it for anything subtle. It isn't faster for boilerplate though, a 200-line CRUD handler I'd have typed in 25 minutes takes four to review. The skill is knowing which category you're in before you start.

It threw me too the first time. Naming it made it much less frightening.

Yes, this is very common and it has a name - the postdrome, sometimes called the migraine hangover. It is a recognised phase, not you recovering badly.

What it looks like for most people I know: fog, word finding trouble, feeling physically bruised or hollow, occasionally a strange flat euphoria, lasting from a few hours to a full day. The clumsiness is a common one that people rarely say out loud.

What helped me manage it, rather than shorten it:

• Treating the day after as part of the episode when I plan. Clearing the migraine day and then booking meetings for the next morning is setting yourself up to fail.
• Not making decisions or sending anything important. I have written some genuinely strange emails in postdrome.
• Eating and drinking early even without appetite.
• Gentle movement, a short walk, rather than either a full day flat or trying to train.

Whether it shortens varies. Mine got shorter as the attacks themselves got better managed, which suggests it scales with how rough the attack was. Worth raising by name with your doctor - it is a real part of the burden and it very often goes unreported.

Concrete thing worth adding regardless of policy: a dependency check. Model-written code adds packages, and a diff that quietly pulls in a new transitive dependency is invisible during a line-by-line review of application code.

CI fails if package.json or the lockfile changed and the PR description doesn't say why. Cheap, and it's precisely the category where line-by-line review catches nothing.

Photos, but with rules, or they are useless. Same corner of the same room, curtains open, no overhead light on, phone propped at the same distance, same time of day, once a week, no expression. I keep them in a dated album and only compare week one to week eight rather than looking at consecutive weeks, because week to week your skin is mostly telling you about sleep and salt. When I started doing this properly I dropped two products inside a season that I would otherwise still be buying.

Reasonable, and worth trying first. The thing to watch is that the context is shared across slots, so eight users with long contexts is where it stops being a fair fight and the batching engine wins.

Put it in writing and keep a copy. Not adversarial, just how these things get remembered six months later.

Numbers, since it decides which tools pay for themselves. Count the jobs you paid a shop for last year, for most people it is a couple of punctures, one gear adjustment, a chain, and a set of brake pads. A shop charge for one of those is roughly what the tool for it costs, so the tools break even in the first year and everything afterward is free. The exception is anything you do once every three years, where the shop is cheaper and you should keep paying them.

Letting 340 cards die feels like setting money on fire, but I take the point.

I used all four in one evening for about five weeks and destroyed my barrier so thoroughly that plain water stung. It took three weeks of nothing but a bland cleanser and a ceramide moisturiser to feel normal again, and I threw away most of an unfinished vitamin C serum because I no longer trusted it. The cost was not the products, it was two months of no progress at all while I recovered.

Before the count, sort the flight path and the water, because those are what turn a hive into a neighbour problem. Put a hedge, a fence panel or even a tall trellis a couple of metres in front of the entrances so the bees have to climb immediately, and they will be well above head height by the time they cross your boundary. Then give them water on your side, closer than the pool, and keep it topped up from early spring before they establish the habit of going elsewhere. Bees fix on a water source and are hard to move off it once they have chosen, so being first matters more than being closer.

This is the whole trick for most codegen honestly. One good example beats three paragraphs of instructions.

The four day experiment is the classic mistake. Nothing about this settles in four days.

Both variables you named, and they compound.

Caffeine first: three coffees on weekdays and none until 11am on Saturday is a substantial withdrawal and the timing lines up exactly. For a lot of people that alone is the whole pattern. What worked for me was not quitting but moving to a consistent smaller amount every single day including weekends, at roughly the same hour. Two cups, same time daily, and my weekend mornings changed within about three weeks.

Sleep second: a three hour lie-in is effectively jet lag. Sleeping past about 90 minutes over my usual wake time was reliably a bad idea for me.

Change one at a time, three weeks each, so you learn which it was. Start with caffeine because it is easier to control and the effect shows up faster. And mention the pattern to your doctor - a clean weekly rhythm like that is genuinely useful information for them.

Letting her do the last two is the part I would have skipped and it is obviously the part that makes it stick.

The thing that changed my aura window was deciding in advance rather than in the moment. When the zigzags start I am not in a good state to make decisions, so I have a written list on my phone and I just do the list.

Mine is:

• Send one message to the person who most needs to know I am about to go offline.
• Save whatever I am working on and close it. Not finish it. Close it.
• Water, and something small to eat if I have not eaten.
• Dark room, phone face down, earplugs in.

The finishing-what-you-are-doing instinct is the trap. Twenty minutes of pushing through has never once made the following four hours better for me, and it often makes them worse.

The medication timing conversation with your doctor is the important one, and for what it is worth mine improved a lot when I stopped waiting to see how bad it would get.

Separate duvets first, earplugs second, separate rooms third. Most people stop at the first one. The ones who don't are usually dealing with snoring, which is a different problem with a different fix.

Write it now while you feel fine. Future you is not going to invent a plan mid-aura.

The promise example is good because it separates the descriptive part, which is fully answerable, from the part that is not, in one sentence.

A useful practical test: ask what observation would change your mind. If your friend cannot name one, even in principle, even with unlimited money and a thousand years, the question is not so much unanswerable as not the kind of thing an answer would attach to. That is not a criticism of the question, plenty of questions worth asking are like that, it just tells you which tool you are reaching for.

The categories that still reward spending more, from things in my house that are old and still working: cast iron and carbon steel pans, hand tools, a mechanical kettle with no electronics, sewing machines, and anything with a real motor that is serviced. The hopeless ones are cheap toasters, most electric kettles, printers, and anything where the value is in a screen or an app. I have a stand mixer past the twenty year mark, and the honest caveat is that it needed one repair and I could only do it because the gears are still sold.

Matches my experience. The best use of a model on a big mechanical refactor is writing the tool that does the refactor.
