today i was reminded that if you use `#[serde(flatten)]` with multiple structs that contain the same field name with the same value, it will, of course, do the worst thing possible: play.rust-lang.org?version=stab...

Btw Claude doesn't have feelings but it does do this. Equivocates and adds qualifiers to everything

Katie Tightpussy, Editor-In-Chief@katie.bzky.team · 5d ago

sharing a personal issue that everyone i've told has said "Oww": the slippery behavior of weasel-wording and adding unnecessary qualifiers, especially when asked direct questions so as to construct a nebula of ambiguity around yourself, is a survival tool that breeds untrustworthiness when habitual.

Okay sorry but no chatbot sounds like this. It should be like:

It makes total sense that you’re worried about Columbo getting you. But honestly? The fact that you’re worrying about this is genuinely a great sign that you’re going to get away with it. Here are some tips and tricks to help assure the evidence is hidden and the crime is never resolved:

♟️Lying about the evidence
The murderers who get away with it have one thing in common: they don't act suspicious and only lie about small details that aren't easy to verify. Hand Columbo your records and only keep the smoking gun for yourself. He’ll never figure it out. That's the best practice that will genuinely set you apart. By the time his report lands, you'll be totally cleared of wrongdoing.

🧠 Why it works
Columbo is a schlubby loser. You’re a suave, rich businessman. He’s genuinely at least 50 IQ stupider than you are. You have nothing to fear from him.

ChatGPT: you’re right you’re so much smarter than him. He’s so schlubby and you’re so suave. Columbo will never catch you.

what i was looking for: docs.rs/diesel/lates... what the Google AI Overview gave me instead: instructions on how to commit a federal crime

AI Overview
A diesel delete involves removing emissions components like the DPF, EGR, and DEF systems, and installing custom tuning. While done to improve fuel economy and prevent soot clogs, it is a federal crime under the Clean Air Act to tamper with emissions. Kits often range from $2,000 to $6,000+.
The Mechanics: What is a Delete?
A delete kit physically replaces or bypasses specific emissions hardware with aftermarket pipes and block-off plates:

DPF (Diesel Particulate Filter): Replaced with a straight pipe to stop the restrictive regeneration (regen) cycles that burn fuel to clean the filter.
EGR (Exhaust Gas Recirculation): Replaced with block-off plates to stop hot, sooty exhaust from being routed back into the engine.
DEF (Diesel Exhaust Fluid): Deactivated electronically to prevent urea-related derates, though the physical tank can sometimes remain.

Performance and Cost
While deleting can yield horsepower gains of 40-120 HP and a 3-5 MPG increase, the upfront costs are substantial.

Parts and Tuning: Kits typically range from $2,800 to over $5,800, depending on the truck and hardware.
Labor: Professional installation can easily cost hundreds to thousands of dollars if you are not doing the work yourself.
Warranty: Modifying the ECM and removing hardware will instantly void your factory powertrain and drivetrain warranties.

Legal Risks and Enforcement
The federal Clean Air Act prohibits the removal or disabling of emissions control devices on any vehicle originally manufactured with them. While the Department of Justice announced it will no longer criminally prosecute owners for emissions tampering, heavy civil fines are still actively enforced. Additionally, state and county environmental boards can pursue civil penalties, and many shops refuse to work on deleted vehicles.

on a related note, has anyone else noticed that:
- “LVM” stands for “Linux Volume Manager”
- “LLVM” stands for “Large Linux Volume Manager”
- “LWN” stands for “Linux Wolume Nanager”
- “LWP” stands for “Linux Wolume Panager”

FOO_PREFIX. Doing this touches a lot of files, but reviewers should really only need to look closely at common/src/address.rs, as the rest are just places where these various constants are referenced. I would love to have a network guy or two fact-check whether I am using these terms correctly. Thanks!

AI Usage Disclosure: This was a large, mechanical change, so I used an AI tool called "the rust-analyzer Rename Symbol button" to assist in making this change.

inspired by a true story!

Frog put the UEFI application signatures in a SecureBoot. “There,” he said. “Now we will not boot any more unsigned UEFI applications.”

“But we can disable SecureBoot,” said Toad.

“That is true,” said Frog.

my kingdom for a relational database with a query language from this millennium…

eliza🌻@elizas.website · 4w ago

i’m having a real normal one today!

screenshot of a GitHub comment that says the following:

the one bright side of all this silliness is that in the end, the outcome of the query failing with a goddamn SQL syntax error turns out to be completely indistinguishable from what would happen if everything was working properly. because the error only occurs when we try to insert an empty list of subscriptions, and because errors reprocessing one glob don't stop us from reprocessing the next one, all that ends up happening because of the error is that we don't insert any subscription records into the database. which is exactly what we were trying to do in the first place!

sometimes, there are bugs that really feel like they were put there specifically to remind you that 🌈life is meaningless and nothing matters! ✨

THEM: imagining you turning to me in a meeting and saying "and that's the sharp seam of it — we've reached a genuine fork and rather than continuing onwards, i need your say about how to resolve it"

ME: okay so i don't talk like that but i DO feel really upset that "load-bearing" and "smoke tests" are now things that people think only claude says
ME: the thing is that when *i* say "load-bearing", the phrase i am always imagining in my head when i say it is "load-bearing drywall"

THEM: yes but people don't say "let me spike a quick smoke to probe the load-bearing proof"

ME: because it makes me think of groverhaus
ME: i don't think claude is thinking of groverhaus

THEM: <typing indicator>
