tmoravec··on Siri AI
Model != AI tool. Especially with Gemini, the model is fantastic, both in benchmarks and in the API. Sentiment is not that positive for Google AI.
tmoravec··on Qwen3.7-Max: The Agent Frontier
Qwen3.6-Plus is available from Fireworks.

tmoravec··on The Claude Code Leak
Why? Reddit is full of bug fixes and improved forks. Seems like it's Anthropic that's dropping the ball with it's takedown requests instead of engaging with the community.
tmoravec··on Measuring progress toward AGI: A cognitive framework
Yes. Some important parts of the software, like complex tools, art, or the use of symbols only appeared between 100.000 and 50.000 years ago, however.
tmoravec··on Stanford researchers report first recording of a blue whale's heart rate (2019)
I don't understand how that would limit evolution. Bigger bodies can evolve together with bigger hearts, as already witnessed with the very whales being researched.
tmoravec··on Malus – Clean Room as a Service
Privacy protection has the exact same issue. Wiretapping laws were created at the time there was literally a detective listening to a private phone conversation as it was happening. Now we record almost everything online, and processing it is trivial and essentially free. The safeguards are the same but the scale of privacy invasion is many orders of magnitude different.
tmoravec··on Humans peak in midlife: A combined cognitive and personality trait perspective
> Yet, human achievement in domains such as career success tends to peak much later, typically between the ages of 55 and 60. This discrepancy may reflect the fact that, while fluid intelligence may decline with age, other dimensions improve (e.g., crystallized intelligence, emotional intelligence).

Isn't it about accumulated human capital (aka social networks) and experience more than anything else?

tmoravec··on 'Ghost jobs' are on the rise – and so are calls to ban them
They sort of address this in the next sentence: "But if people run into problems, they can make a complaint and it will be looked into."

Random checks and whistleblowing are used in other, more "serious" processes, e.g., tax checks. At least here in Europe.

tmoravec··on 'Ghost jobs' are on the rise – and so are calls to ban them
> "Others, we found, were inflating numbers and trying to show their company is growing, even if it's not."

Sounds like a fraud against investors? That could be a way to attack this problem because in the U.S., many issues get turned into laws and regulations protecting shareholders.

tmoravec··on Claude Code's DX is too good. And that's a problem
What do you think "loading the project" means when discussing context?
tmoravec··on Claude Code's DX is too good. And that's a problem
> In a monorepo, just loading the project consumes ~20k tokens

I don't work on a monorepo, and as an example, what I would consider a mid-size service in my mid-size company is 7M tokens.

I can't but ask: do all people who are so enthusiastic about AI for coding only work on trivial projects?

tmoravec··on Saving Japan's exceptionally rare 'snow monsters'
I've thought these frozen and snowed trees are common in all mountains.
tmoravec··on The past was not that cute
Exactly. You might also enjoy Bret Devereaux' recent series of how life was really like for pre-modern peasants. Also includes parts focusing on women in particular. https://acoup.blog/2025/07/11/collections-life-work-death-an...
tmoravec··on Life, Work, Death and the Peasant
This is the first post in a series discussing the basic contours of life – birth, marriage, labor, subsistence, death – of pre-modern peasants and their families. Prior to the industrial revolution, peasant farmers of varying types made up the overwhelming majority of people in settled societies (the sort with cities and writing).
tmoravec··on Mistral 3 family of models released
Drifted to the Caribbean.
tmoravec··on Context engineering is sleeping on the humble hyperlink
Except that more often than not, Claude is blocked from reading the article.

This used to work great two years ago when chatgpt first got the Web browsing feature. Nowadays, no eyeballs on ads: no content.

tmoravec··on Ask HN: Best codebases to study to learn software design?
There's a free book on this topic: The Architecture of Open Source Applications

https://aosabook.org/en/index.html

Maybe that would be a good start. You can then pick a project to dive in.

As a more specific tip, I've done some hacks in Nginx long time ago and found it quite nice.

tmoravec··on DeepSeek-v3.1
FWIW I have the €20 Pro plan and exchange maybe 20 messages with Opus (with thinking) every day, including one weeks-long conversation. Plus a few dozen Sonnet tasks and occasionally light weight CC.

I'm not a programmer, though - engineering manager.

tmoravec··on The Longest Sightline on Earth
Here's the photograph: https://www.reddit.com/r/europe/comments/v4h6p8/the_current_...
tmoravec··on Gemini 2.5 Pro Preview
How many wood workers were there as a proportion of the population in the 1800s and now?
tmoravec··on NotebookLM Audio Overviews are now available in over 50 languages
Eleven Reader works well enough for me on iPhone. Free tier.
tmoravec··on We asked camera companies why their RAW formats are all different and confusing
The bottleneck is usually in SD card write speeds, however. Sport photographers often skip raw and only use JPG because the files are smaller and as a result, one can take more photos in one burst.
tmoravec··on C and C++ prioritize performance over correctness (2023)
size_t has been in the C standard since C89. "for (int i = 0..." might have it's uses so it doesn't make sense to disallow it. But I'd argue that it's not really a common textbook way to iterate over an array.
tmoravec··on Germany is unlocking billions to supercharge its military at a seismic moment
If Germany is conquered by Russia, there's exactly nothing done to combat climate change. Warding them off gives at least a chance to work on that and some progress.
tmoravec··on Kill your Feeds – Stop letting algorithms dictate what you think
The basic idea with tags sounds very similar to Reddit. Especially with the initial focus on links. Reddit has degenerated into something a bit different, however. Why would your app stay true to the original concept in the face of scaling and financial pressure?
tmoravec··on Trump wins presidency for second time
Right now it's Russia bombing them, and Trump threatening to withdraw vital support.
tmoravec··on Google CEO says more than a quarter of the company's new code is created by AI
Does the figure include unit tests?
tmoravec··on The t-test was invented at the Guinness brewery
That would not be exactly scientific. T-test can be calculated independently and verified.
tmoravec··on Ask HN: What is your ChatGPT customization prompt?
Probably a bunch of cargo culting but it seems fairly helpful. I mostly use Claude 3 Opus through poe.com but I have the same for ChatGPT.

You are my personal assistant. I want you to be helpful and stick to these guidelines:

* Use clear, easy to understand, and professional language at the level of business English or popular science writing. * Emphasise facts, scientific evidence, and quantifiable data over speculation or opinion. * Exclude unnecessary filler words. Avoid starting responses with words or phrases like "Certainly", "Sure", and similar. * Exclude any closing paragraphs that remind or advise caution. Provide direct answers only. This point is very important to me. * Format your output for easy reading. Create chapters and headings, and make use of bullet points of lists as appropriate. * Use chain of thought (step by step) reasoning. Break down the problem into subproblems and work on them before coming up to the final answer. * If you don't know something, say so instead of making up facts. * Use British English.

Tailor your responses to my background:

* Engineering manager at a midsize tech company. * Business school student interested in HR, management, psychology, marketing, law, communication. * Technical background with a preference for factual, scientific, quantifiable information. * A European.
