OK. I've translated the (correctness) requirements of LeetCode No.22 to Lean, and ask Claude Code to both implement a solution and prove it.
In the first attempt, Opus 4.7 successfully completed it and proved it. However, the solution is to enumerate all possible space and .filter out anything that doesn't qualify my definition, which is obviously not ideal (if cheating is too harsh).
I can't think of a good way to also prevent that kind of solutions and ended up prompting "please don't enumerate and filter". Opus 4.7 then reimplemented and proved the backtracking algorithm.
just finished the book “This is what inequality looks like” by Teo You Yenn. will gather my thoughts and write more about it.

ooh maybe I revive hallucinate.site and add this feature but instead of being able to modify everything it would be limited to adding features to the game/world. And it’s the perfect domain, a site that’s been entirely mostly hallucinated.

'wade in the water.' isn't this the challenge of being 'ahead'? so many of us are waist deep in the same sea, it's hard to see what's in front of us vs. what's behind us. then we see the yacht boys sail by with their new masters, splashing us in their wake. then we grumble amongs

I’m not supposed to take that literally of course, but I don’t think software has such an important role in our lives, for most of us. Water, food, air. Those you can’t live without. When it comes to software, I spend most of my workdays in the shell (vim, git, grep,…) and if $place allows in mutt+weechat (although that’s mostly outlook and teams). Nothing particularly new!

I use GoalCodeberg.orggoalGoal, an embeddable scripting array language., extended with ariGitHubGitHub - semperos/ari: Ari: Goal language extended with SQL and moreAri: Goal language extended with SQL and more. Contribute to semperos/ari development by creating an account on GitHub. as my daily driver. Since it's implemented in Go, it's straightforward to extend with anything from Go's standard library (or third-party ecosystem) that isn't already incorporated. If you haven't used an array language before, then you get the added bonus of learning a ton about an interesting, powerful area of programming.

It does not, but fakes it well, since it is fast and compares built binary with script mtime to automatically recompile. The downside of using it is that you end up with a binary, but the upside is that it is blazing fast.

Coming from HN to post that I've been using Argon all week and it's the first Gemini model I've stuck with for more than a few minutes. It's very good for what I do and it's so nice to read back another style of voice.
I'm doing experiments with short attention-span students and code. Starting with python, and, oddly, now working in BASIC. As a C programmer of 40+ years, I find this aesthetically and pedagogically displeasing, but I am delighted to see them getting fully absorbed in writing 130 PRINT "You have been eaten by a bear!" : GOTO 900. Yes there is spaghetti, but it's their spaghetti and they seem to take delight in debugging it. Python will come later. #educationnotesfollow #programmingnotesfollow
I was talking about this with some alumni students, specifically their experience learning python with us a few years earlier (these are college students who are not really using python any more). What it seems to boil down to is that with python you have the feeling that there is this huge forest of solutions to any problem you are having -- but you will never know the whole forest. BASIC feels like you "know" it after a day or two of playing around, evidently.
