Tell it to ignore rationalist talking points and you’ll get different answers. Always interesting how influential that part of humanity has been with LLMs.

Confidence scoring is fine when you provide the right context, like everything else LLM related. I use grading scripts for things that can be measured directly so the LLM just operates on it. For things less well-defined, I use a grading matrix with explicit criteria on what constitutes an A to F grade, usually with an assumption of an A grade that drops depending on specific findings.

If you are asking about confidence and somehow it can’t be defined either mathematically or in a grading rubric, then you the implementer need to start asking yourself the questions, because then you got a target that you don’t even know how to measure. The LLM isn’t even the problem at this point because another human would also just be going off gut feeling and vibing a number that may or may not be accurate.

I try to do the same thing, but I just don't see these very large savings. I can't even really justify the $200 or $100 tier off of it. I usually can match it immediately or beat it with just some brief Googling. I simply don't think the price arbitrage just really exists in any reliable way, month to month. Its more of a bonus if it happens to work out.

My tests in the past month, basically $0 saved over my findings: - Two one-way flights - New OLED 55"- 65" TV - Mini PC for CI/CD runner, with very specific specs - Expensive, specialized medical device - Variety of car parts

I think one problem is that I simply already know the places to check for this stuff. The more esoteric places (ebay/fb marketplace/etc) agents seem to just be awful at parsing what is real, what is a scam, what is a good deal, etc, and that is where the big deals are for stuff.

Good thing you spawned into the world as a fully formed adult and never had to be a burden on society, unlike all these other _kids_ and their greedy parents.

You do realize today’s kids are going to be feeding you, delivering your groceries, keeping your electrical and water running, farming your food and so on when you are old. Probably far before you are old. Unless you live alone on a farm homesteading, the anti-natalism is ridiculous.

The author suggests humans are overturned to repairing skin and blood, but I strongly disagree. People with problems with wound healing can face significant disability and mortality. Wound healing allows us to have surgery and close up with simple sutures. A lot of complications post-surgery in humans and other animals are specifically from impaired wound healing capability. It’s a good trade-off: nearly everyone will eventually get cut open by accident or on purpose. The skins ability to heal is so amazing that many types of wounds require nothing other than some cleaning, the body will fully clot, bridge, build, and scar back to most retained function. Wound healing allows us to heal large burns and even simply leave many wounds open to air.

Complications with healing are pretty brutal. Necrosis, amputation, infection are all common without the built-in cascade we have.

Motor oil is a wear product with a lifespan. It will become saturated with microscopic particles of metal and end up with lower lubricity. You are just slowly grinding away all the metal off the moving parts. Eventually the tolerances will fail, usually a rod bearing, leading to self-destruction of the motor.

Any magic tool that declares a savings of over 10% can be immediately classified as snake oil. You can check yourself, load any of those projects up in GitHub and notice the math is always extremely misleading. It will be something like theoretical input bytes, or amount of command stripped off, or some other lie.

If the tool won’t be upfront about those things, they are not worth looking into any further. It’s used car salesman strategy.

A bunch of sections of the README are nonsensical as well. I'll just file this under "magical token-saving project #481 of 2026 that probably performs worse than the harness" for now.

3d printed guns are just a fancier pipe gun. Physics is the real enemy here. Make thing go fast out of tube is too simple of a design.

The building is cheap, the labor is expensive. I built a much larger shed in volumetric space last year for 1/4th the cost.

Not frictionless, so it will also slowly degrade over time. It just has so much mass built-in that it’s not obvious.

Not really. Private health insurance would still exist alongside for the more wealthy (including nearly everyone on HN) that doesn’t want to wait a year for their public system MRI. Same thing that plays out in other countries. The U.S. already has a form of this in so-called concierge / premium providers too. Lots of profit to be made.

This is where I landed too. Basic skill for a Jira-like task board and another for keeping an orchestration ledger. Let’s me arbitrarily clear context without losing big picture knowledge.

This wording is inaccurate. It isn't about "modern" heat pumps, its about if another $2-3,000 of electronics and clever injection systems are worth letting the refrigeration cycle work at the extremes. For a lot of the U.S. there is just no need to have a system that is a lot less repairable just to get that efficiency below 50F. The complexity differences between a variable speed system that can work over a 100F degree range and a standard single stage system with just a reversing valve are pretty big. The cost is basically never regained in savings in large parts of the southern U.S. so you just don't see them unless they are overseas models made with cheap labor; meant to be thrown away when they break.
