Re:Why LLMs Can't Build Software on Thursday August 14, 2025 @12:47PM (#44902672)
It's not that they can't build a mental model, it's that they don't attempt to build one. LLMs jump straight from text to code with little to no time spent trying to architect the system.

The same is true of humanity in aggregate. We attribute discoveries to an individual or group of researchers but to claim humans are efficient at novel research is a form of survivorship bias. We ignore the numerous researchers who failed to achieve the same discoveries.

Re:LLMs are mirrors of operator skill on Wednesday June 04, 2025 @11:27AM (#44181796)
A thing people miss is that there are many different right ways to solve a problem. A legacy system might need the compatibility or it might be a greenfield. If you leave a technical requirement out of the prompt you are letting the LLM decide. Maybe that will agree with your nuanced view of things, but maybe not.

We're not yet at a point where LLM coders will learn all your idiosyncrasies automatically, but those feedback loops are well within our technical ability. LLM's are roughly a knowledgeable but naïve junior dev; you must train them!

Hint: add that requirement to your system/app prompt and be done with it.

Well I'm certainly not saying that AI should generate more corporate spam. That's part of them problem! And also a strawman argument!
Re:My AI skeptic friends are all nuts on Tuesday June 03, 2025 @01:59PM (#44172764)
A big challenge is that programmers all have unique ever changing personal style and vision that they've never had to communicate before. As well they generally "bikeshed" and add undefined unrequested requirements, because you know someday we might need to support 10000x more users than we have. This is all well and good when the programmer implements something themselves but falls apart when it must be communicated to an LLM. Most projects/systems/orgs don't have the necessary level of detail in their documentation, documentation is fragmented across git/jira/confluence/etc/etc/etc., and it's a hodge podge of technologies without a semblance of consistency.

I think we'll find that over the next few years the first really big win will be AI tearing down the mountain of tech & documentation debt. Bringing efficiency to corporate knowledge is likely a key element to AI working within them.

Wouldn't the fact that another group researched ABCA1 validate that the assistant did find a reasonable topic to research?

Ultimately we want effective treatments but the goal of the assistant isn't to perfectly predict solutions. Rather it's to reduce the overall cost and time to a solution through automation.

The thing with vague requirements is that the real problem is that making decisions is hard. There are always tradeoffs and consequences. Rarely is there a truly clear and objective decision. In the end either you or the LLM are guessing what the best option is.
Re:The Northeast is becoming fire country on Wednesday November 20, 2024 @03:48PM (#42197954)
I'm not sure about that but in that scenario polar regions would be 75-85F and life would be very harsh just about everywhere else. The one period in time where temperatures were that high, the Paleocene–Eocene Thermal Maximum, diversity plummeted, mammals were smaller and migrated to higher latitudes.

> All those diagrams, when they are complete, correct and up-to-date, do convey what they are supposed to convey.

I spent a bit of time prototyping this recently. It's definitely possible. Rational Rose also had the capability to generate diagrams from code though. I don't remember how good it was at the task though. Was Rational Rose just a very bad implementation?

I find the hate in this chat strange because diagrams are incredibly useful when working through complex problems* and then conveying that information to other engineers. My experience over 20+ years is that a huge portion of engineers can't grok complex problems from code alone.

*Most of my projects are optimizing billion+ row databases, micro-service architectures, and various other scaling challenges.

If you get to use a tool, then so does the LLM.
You're focusing too much on what the LLM can handle internally. No LLMs aren't good at math, but they understand mathematic concepts and can use a program or tool to perform calculations.

Your argument is the equivalent of saying humans can't do math because they rely on calculators.

In the end what matters is whether the problem is solved, not how it is solved.

(assuming that the how has reasonable costs)

I've noticed a big trend by commercial entities claiming to be "Open Source" but actually charging for licenses. Just because your code is in a public repo on github doesn't mean it's open source. If it's not an open source license it's not open.

This is especially true of AI projects.

Re:Ask HN: What is your opinion of “unlimited” PTO? on Wednesday January 11, 2023 @11:46AM (#34340593)
Usually when a company is moving from PTO to DTO they are just trying to get the liability off the books. Management knows that most employees, especially new hires, don't take all of their days. It does nothing to help employees but that is how it is pitched.

If employees were actually utilizing unlimited DTO the company would switch back to accrued PTO. I've seen this happen with an explicit claim that employees were "abusing" the generosity of the company. Said company later switched back to DTO to force employees a few years later to burn down their accrued PTO balances.

That's not a friend, that's a co-worker doing their job. There's a big difference between a friend and someone you get a long with well in a professional setting.

I've seen systems that use waste heat from central A/C to heat a swimming pool. In addition to the condenser they have a heat exchanger connected to the coolant line. Pool water is pumped through the heat exchanger and back out to the pool.

Re:Iron Cycle based energy storage and generation on Wednesday April 13, 2022 @04:25PM (#31019807)
I've wondered whether you could pump heat from a solar panel into a swimming pool.

I've seen systems where heat from A/C is used to heat swimming pools. Mostly just needs an extra exchanger on the A/C coolant line that transfers the heat to the pool water. You generally run both system at the same time when it's hot out. (assuming you are fortunate enough to have a pool)

Re:Senior devs. Is anyone else insulted by coding exams? on Wednesday March 09, 2022 @03:33PM (#30619593)
An algorithmic question is a coding problem that focuses on problem solving, and may include questions/constraints related to time & space optimization.

The test should never rely on rote learning (e.g. implement Dijkstra's algorithm from memory) or require a "magic" solution (e.g. Project Euler)
