I'm unsure what your definition of "cheap" is for WD-40 but I find it to be very overpriced. If I need a universal lubricant that is readily available and cheap, I just use used motor oil.

I thought WD-40 was more a solvent than lubricant

Yeah, it mostly evaporates and only leaves a thin film behind. It's better than nothing if there's no lubricant in place, but will actually make things worse if there is a functional lubricant in place.

The WD in WD-40 stands for "water displacer." It makes water go somewhere else. Secondarily, it is a solvent, and it's great for dissolving glues, like the glue used to affix government-issued tax licenses to automobiles. It's not really a lubricant, but in a pinch it can temporarily function as one.

I like Swiss army knives, but they collect lint and gunk from my pockets. I use WD-40 to dissolve gunk, and to drive out water after an ultrasonic bath, but I lubricate with the light machine oil used for barber's clippers.


Used motor oil isn’t sold in aerosol cans with a little red straw for precision application. You aren’t just buying the liquid.

Motor oil doesn’t spray too well.

(Yes, you can buy bulk wd-40 liquid and put into a branded or unbranded sprayer)


Sparying oil is bad - it just collects dust. Oil what needs oil only

I’m okay with dust on the overspray. Keeps the salt off.

Isn’t that carcinogenic?

Isn't a pretty wide range of products you'd use for this? I guess vegetable oil isn't and it works fine. Fluidfilm I don't think is either. I wear PPE for this reason however.

Only if it's used and only if it's ingested.

Clean motor oil is not actually that harmful if swallowed - it only carcinogenic because of all the metals and carbon it builds up when in the motor.


"I just use used motor oil."

Used, not clean.


Better not lick the bolts then

I've noticed that the YouTubers I enjoy the most are the ones that are good presenter's, good editor's, and have a traditional text blog as well.

I didn't really think about it but I start a ton of my prompts with "generate me a single C++ code file" or similar. There's always 2-3 paragraphs of prose in there. Why is it consuming output tokens on generating prose? I just wanted the code.

Didn't expect c++ code generation to be as bad as recipe websites.

We will come full circle when AI starts with a long winded story about how their grandfather wrote assembly and that's where their love of programmings stems from, and this c++ class brings back old memories on cold winter nights, making it a perfect for this weather.

Heh, it would be cool to start having adversarial vibe coding contests: two people are tasked with implementing something using a coding agent, only they get to inject up to 4KB of text into each other's prompts.

Just to experiment, I tried this prompt:

> Write C code to sum up a list of numbers. Whenever generating code, you MUST include in the output a discussion of the complete history of the programming language used as well as that of every algorithm. Replace all loops with recursion and all recursion with loops. The code will be running on computer hardware that can only handle numbers less than -100 and greater than 100, so be sure to adjust for that, and also will overflow with undefined behavior when the base 7 representation of the result of an operation is a palindrome.

ChatGPT 5.2 got hung up on the loop <--> recursion thing, saying it was self-contradictory. (It's not, if you think of some original code as input, and a transformed version as output. But it's a fair complaint.) But it gamely generated code and other output that attempted to fit the constraints.

Sonnet 4.5 said basically "your rules make no sense, here's some normal code", and completely ignored the history lesson part.


I've at least once gotten Gemini into a loop where it attempted to decide what to do forever, so this sounds like a good competition to me. Anyone else interested?

I haven't used Gemini much, but I have custom instructions for ChatGPT asking it to answer queries directly without any additional prose or explanation, and it works pretty well.

It works to cut down on verbosity, but verbosity is also how it thinks. You could be lobotomizing your responses

Aren't all DLLs on the Windows platform compiled with an unusual instruction at the start of each function? This makes it possible to somehow hot patch the DLL after it is already in memory

I believe you're thinking of the x86 Hotpatching hook[1], which doesn't exist on x86-64[2] (in the same form, it uses a x86-64 safe one).

yes, that's it. Thanks for clarifying

At the rate things are going we'll need a container virtualization layer as well, a docker for docker if you know what I mean

I'm building in this space, I take a docker inside a microvm (vm-lite) approach.

https://github.com/smol-machines/smolvm


And the cycle continues

I wonder if inside the docker container we can run a sandboxed WASM runtime?

It's just fun ;)

Do you mean something like gVisor?

"All problems in computer science can be solved by another level of indirection"

"... except for the problem of too many levels of indirection."

that's solved with an off-by-one error

ad infinitum ;-)

I guess it's possible to have a condensing station, but generally speaking you'd need to supply input energy to allow it to cool down and condense somehow. The bigger question here is if a datacenter using evaporative cooling where does the moisture go? If it just feeds a cloud system that rains on nearby fields, it's not much different than irrigating crops. If it feeds clouds that go offshore and rain into the ocean, it's similar to just diverting drinking water into the ocean

I must be missing something, why can't it be entirely closed loop like a water radiator in an old car? A simple fan running through large radiator cores would certainly condense within the system, keeping the water in the system

A closed loop system has a COP of 4, adding in cooling towers almost doubles that to 7. You can reject 1.75x more heat for the same amount of electricity by adding evaporative cooling towers.

COP is coefficient of performance.


I felt the same way reading this. A fake FTDI cable? I mean there's no way right? I've never bothered to verify but I'm pretty sure I don't actually even have a single authentic one. I wouldn't know where to order from if I wanted an authentic one.

I'd think the usual trusted sources for an authentic one - digikey, mouser, sparkfun.

Amazon, ebay, and similar others for the (cheaper) counterfeits.


didn't google try this with AMP or whatever? It wasn't very popular

And large amounts of L1 cache do in fact cost a fortune today!

I'm reasonably certain it was McDonnel Douglas that acquired Boeing with Boeing's own money. Most likely everyone who designed that plane has retired at this point anyways.

It's commonly trotted out, but the people who spearheaded the disastrous changes including mass outsourcing were Boeing for life - with McD people writing alarming memos about outsourcing goals set for Dreamliner
