Demanding an estimate guarantees the estimate will not be useful to the business and will always drive costs up.
Software engineers all know that estimates are useless.

I'm not a fan of story points; I don't use or recommend them.
That said, they can have some value inside the team when used as originally intended. The original XP team invented story points to obfuscate time estimates from management.

“Too many GPUs make you lazy.” One way to address AI energy usage is to improve (and specialize) the models. Mistral is a good example of that: t.ly/6dTxd

The AI/LLM haters are legion, but they have a very real concern about the environmental cost of the tech. To say that all LLMs burn down the planet is simplistic, however. We have to evaluate the vendors and models and choose based on their commitment to clean energy.

Maybe the third time's a charm 😄. Yesterday, I posted that we could eliminate things like country-name dropdowns and replace them with free text, perhaps using an LLM to correct errors.

So, a few weeks ago, I posted about those ridiculous country-name drop-downs with 100 or more lines and similar 50-line ones for US state codes. (Don't get me started on year-picker dropdowns with 100+ sequential numbers in them 🙄.

I keep reading posts about people who wrote applications entirely with "zero coding." They say they don't read the code and instead refine the application using increasingly precise prompts. I have some questions:
* Is the application nontrivial?

I've noticed that the new way trolls discount ideas that make them uncomfortable is by accusing me of being an LLM. Since these comments almost always refer to me as "that guy" or "buddy," I can't help but wonder if they are LLM-generated 😄.

High school students using AI to write college application essays that are then graded by AI from admissions departments is a great example of how AI usage devalues systems while people can accurately point to “productivity gains” from using AI.

A few days back, I wrote about how AI can be useful, and that we ignore or reject it at our peril. Paradoxically, as several people pointed out, some not very politely, longer-term productivity in many (maybe most) shops that use AI code generation has gone down. That's absolutely true.

How do you measure productivity? Let’s start by talking about the engineering obsession with quantitative metrics. You can easily measure productivity on an assembly line. The faster a car comes off the line at a given quality level, the more productive you are.

Discounting a technology or process because the evidence is "anecdotal" is a straw man. There are no studies for most practices & tools, and when there are, the numbers are flawed. For example, you cannot measure productivity using PRs or KLOC. Generating lots of garbage quickly is not productive.

This is a common argument against AI. All the AI does is create code, which is the easiest part of software engineering. Humans are the architects. Humans assure the quality. It's like building a house with unskilled labor that requires supervision. No thinking is outsourced. LLMs can't think.
AI assisted software engineering is a horrible idea.
It's like building a house by asking a fortune telling automaton.
you outsource critical parts of your thinking and analysis, give up crucial abilities, and end up with houses that cave in on people.
Eventually.

Of the critical responses to this post that weren't just invective and name-calling (I've blocked those particular people), one important observation was that people complained about having to deal with AI-generated garbage that other people checked into the repo. 1/

I just read an article about "dumb phones." There is a class of people who have decided that smartphones are evil, so they've returned to phone technology circa 1990. No apps. No big screen or QWERTY keyboard. Just a phone (and txt).

Normally, I wouldn't hoist a post like this 👇 to the top level, but this is a great example of someone who can be easily replaced by Claude Code. When a machine can write the code for you, other factors become more important. Just sayin'.
I give no fucks about your compney "culture" your values or you personaly. I offer skills you offer a job that needs to be filled. Im not there to make freinds, not there to "be part of the family" i am there to WORK. then i GO HOME and never do those things mix.

Why is it that when I posted about culture, recently, very few people seemed to think I was talking about a culture of kindness, respect, trust, and inclusion? Judging by the comments, the situation in the software industry is bleak. Read Sheridon's "Joy Inc." There's a culture I can get behind!

George Floyd died in 2020, so the US said, "OMG! Racism is bad! We can change!"
In 2021, the US *talked about* some modest reforms.
In 2022 and 2023, white grievance against those reforms had reached fever pitch.
2024 saw record police funding, record cops killing Black people, and DEI rollback.🤷🏿♂️
