we all must learn that we live in a bubble in our own unique ways
aww, OWC will sell you 128TB of flash in a briefcase shaped computer with a handle on top, but it's all U.2

(it is in fact targeted for "video teams" though)

oh i bet it's HighPoint who will sell you the closest thing to this

...also U.2. dang. EDSFF still really hasn't reached the commercial video power user market yet. wow. clearly i live in a bubble!

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.

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!

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.

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! ✨

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

one of @bcantrill.bsky.social's recent blog entries, bcantrill.dtrace.org/2026/04/12/t..., really comes to mind here
You see, people in general are lazy.
The laziest of the lazy people then usually become programmers and the laziest of those then become the very good programmers.

This is because as a programmer, if you do it right, you only once have to teach a computer how to do something and after that it will just do its thing and you can return to doing nothing. But you can only do nothing in peace if you can ensure that the computer will actually do its work correctly.

Because of that, you'll try your hardest to build bug-free software that just works because the last thing you want to do is actually work in front of a computer.

This inherent drive to not work at all and especially not with computers is the feedback loop and incentive system that creates great software.

The court also stated that:

“In light of the Harrier Jet's well-documented function in attacking and destroying surface and air targets, armed reconnaissance and air interdiction, and offensive and defensive anti-aircraft warfare, depiction of such a jet as a way to get to school in the morning is clearly not serious even if, as plaintiff contends, the jet is capable of being acquired 'in a form that eliminates [its] potential for military use.'[7]”
