I was an avid GReader user and then lost all of the feeds when they closed down. I've been setting up miniflux lately, but the biggest problem is that over the years I've completely lost all blogs I used to follow (and many of them stopped writing anyway), so it's basically starting from zero. But it's already more interesting than trying to scourge Reddit for a non-marketingslop post to read.

I also configured it to fetch Hacker News with some filters to get rid of AI related posts, and it's actually a good way to follow this also.

Articles like this always make me wonder "there could be something interesting about this", but they always assume I know more math (or something) than I do.

Does anyone write about these kinds of topics in a more approachable manner, or is the math just so inherent to this, that I need to learn that first? (And if so, what do I need to read to learn that?)

In some ways I like the concept. Making interesting papers easier to find and easier to digest seems like a good thing.

But the popularity metrics and AI aspects seem like they will cause a bias towards certain types of papers, making potentially useful ones not get found.

New comment by jhartikainen in "Read Programming as Theory Building"

jhartikainen — Sat, 09 May 2026 18:30:42 +0000

In theory maybe in some sense, but if we read Naur's definition of "theory" in a more strict or philosophical way, they can't in full. An LLM can't build a theory, because it doesn't have "real" experience, it's essentially just following rules. It also can't really argue or justify its choices like a person can.

This is discussed in the "Ryle's Notion of Theory" section of the original essay.

This is too realistic, I'm super stressed out now because I didn't have time to answer everything right. Next thing I know, there's probably going to be something embarrassing on my FB timeline!

http://www.ribbon.co uses Angular both for checkouts and creating/editing products.

Disclaimer: I worked with them implementing that.

Would be interesting to hear if you discovered any downsides to Angular. I've been working with it a lot lately, but it seems to be a really good solution and the only issues with it is it can be hard to set up to be compatible with googlebot and the slightly tough learning curve

New comment by jhartikainen in "Why would you want to own a car if you could avoid it?"

jhartikainen — Thu, 15 Aug 2013 09:57:51 +0000

Living in a country with less population than in New York pretty much means you can own a car and won't have to worry about traffic jams and stuff. And in less populated parts of the country you need a car in order to get around to begin with.

Plus some of us enjoy driving as pointed out in a few other comments too

I think it's going to be interesting to read about this as I'm sort of building a SaaS myself as well. Subscribed to the blog feed

This might be a bit disturbing if used by teams who work from home...

I'm not sure what posts like this look to achieve. It's never going to change the main problem crowd: angry kids who get pissy about the tiniest things. They're the ones being abusive on forums etc. as well.

Looks interesting, but I get the feeling using something like ScreenHero would work better. I've used ScreenHero for sort-of pair programming and it works extremely well + it's not limited to editors.
