Do you use Redis Streams? What do you think about my latest PR to Redis? Thanks! github.com/redis/redis/...
Streams: garbage collection and node merging. by antirez · Pull Request #14689 · redis/redis
Streams have a fundamental problem with deleted entries: they are just marked as deleted (STREAM_ITEM_FLAG_DELETED) but the memory is never reclaimed. Over time, streams with heavy XDEL usage accum...

Make sure to check lobste.rs comments on my blog post, if you are interested in the topic of AI coding. They are better than HN comments about the same post.

HN worst feature ever: if there are a lot of comments compared to votes, the post gets suppressed. Imagine a site where people (in theory very informed human beings) discuss stuff, that does everything to suppress controversial things.

It is impossible to understand how the Italian government is ok with what it is happening in Venezuela. Maybe Meloni forgot that the white minority there is of strong Italian heritage, the fact Italians massively helped building Venezuela, and the relationships we had for decades.

Just to say that I wanted to run the GTE-small embedding model in pure C, without any dependency, and Claude Code wrote the 917 lines of code needed in 4/5 minutes. Perfect match with the huge codebase needed by Python to perform the inference. Same speed (!) as PyTorch.

In a single session with Claude Code (Opus 4.5) I implemented, in my "linenoise" library: UTF-8 at the right complexity point (I had two PRs in the past: one too simple, one too complex), and my dream: a testing framework simulating a VT100 terminal!

So thanks to Claude Code if my PRs will get into Redis, "make test" will pass again on slower (i5, in this case) computers. Incredibly boring tasks to do, for humans, to detect timing related failures in tests. But not for the AI, that unstoppably debugged the problems.

Recently I got a Dell Latitude 7420, refurbished. I installed Fedora with Plasma. And after a few days of using it:
1. I severely overestimante the MacBook experience. This hardware is a lot less capable, but the keyboard is better, the plastic feel and the small weight are awesome.

So right now for MANY new projects I would:
1. Create the first core alone or with LLM web interface assistance if needed. Shape *every* line.
2. Start building more with agents, using specification.md files, to put the agent in the right design direction.
3. Coffee as it codes.
4. Review. GOTO 2

I believe we are no more into the stage where the LLM + human in the loop is the best approach for many projects. Sure, reviews are needed, but at this point what coding agents can do is simply incredible. Last few weeks were as shocking as the first ChatGPT version.

StackOverflow chart of death interpretation: LLMs killed it so fast because it was already losing users because of the social issues generating inside the site. Otherwise, SO could be the place where certain quality conversations continued to happen, and also a great source of LLM training.

Wars for oil, again. Since I'm a small child I see the United States bombing other countries to control oil. This also shows that Trump is not just generally a disaster for Americans but *at least* the foreign policy is less aggressive. It's 360 degrees bad.

At this point the average level of discussion within Hacker News threads when the topic is AI is: a bunch of normies drinking beer in some café and cursing the government, their football team coach, and their ailments.
