There are now a few sync engines that tackle this problem. Rocicorp Zero, Electric SQL, and one or two others. By no means a crowded space, but there are options now.

Have you had a chance to use either of these yet? Electric looks like an obvious mature choice — curious if you think Zero's approach is compelling enough to be worth trying in alpha

Hello! I wrote this simple prime number grid visualiser last night, just for fun. It is inspired by the "Show HN" post https://news.ycombinator.com/item?id=44888548 that I stumbled upon a few days ago.

My tool uses the Miller-Rabin primality test with prime bases drawn from https://oeis.org/A014233 to determine whether a number is prime. This allows it to handle numbers up to 3317044064679887385961980.

For example, https://susam.net/primegrid.html#3317044064679887385961781-2... shows the upper limit of the numbers this tool can check. The three circles displayed there represent the following prime numbers:

  3317044064679887385961783
  3317044064679887385961801
  3317044064679887385961813

I hope this is fun for you too!

Thank you for making and sharing this! It's fun to quickly increment the column counter and spot repeating patterns over time — little spiral movements, big swinging lines.

Growing up I loved math's logic puzzle elements, but it got tough when presentation of the subject became more abstract in late high school and college. Visualization tools like this would have gone a long way toward making the concepts concrete and keeping me curious about the relationships behind the symbols.

To the point of the paper, it has been a somewhat disturbing experience to see otherwise affable superiors in the workplace "prompt" their employees in ways that are obviously downstream of their (very frequent) LLM usage.

I started noticing this behavior a few months ago and whew. Easy to fix if the individual cares to, but very hard to ignore from the outside.

Unsolicited advice for all: make an effort to hold onto your manners even with the robots or you'll quickly end up struggling to collaborate with anyone else.

Has anyone tried Basement's typed xmcp framework [1]? I rolled my own mcp server implementation earlier this summer and it works but it's very basic.

I'm considering migrating, but time is limited and I'd love to avoid a dead-end if I can :p

I dunno about that, the HN community has had a curmudgeonly streak as long as I've been a part of it (~15 years). Not exclusively, but... persistently!

At least from the outside, OpenAI's messaging about this seems obnoxiously deluded, maybe some of those employees left because it starts feels like a cult built on foundations of self importance? Or maybe they really do know some things we don't know, but it seems like a lot of people are eager to keep giving them that excuse.

But then again, maybe they have such a menagerie of individuals with their heads in the clouds that they've created something of an echo chamber about the 'pure vision' that only they can manifest.

shredprez · 2 months ago

Ehh, this take feels ungenerous to me. You don't have to believe a private firm is a holy order for it to benefit from a culture filled with "we believe this specific project is Important" people vs "will work at whatever shop drops the most cash" people.

Mercenaries by definition select for individual dollar outcomes, and its impossible for that not to impact the way they operate in groups, which is generally to the group's detriment unless management is incredibly good at building group-first incentive structures that don't stomp individual outcomes.

That said, mercenary-missionaries are definitely a thing. They're unstoppable forces culturally and economically, and that could be who we're seeing move around here.

Yes. That would be great info.

It is infuriating that they keep using the median household income compared to the average upfront cost.

shredprez · 2 years ago

Where broker’s fees are concerned, up-front cost is typically first and last month’s rent, plus the broker’s fee, which can be as low as one month’s rent or as high as 15% of the annual rent total (almost twice the cost of a single month’s rent).

Apply the rules above to whatever the average rent is for a given neighborhood, and there you go.

Another insidious element of these broker's fees are "good faith deposits." In my case, this was the full brokers fee paid via zelle,lease unseen, and with no contract in place other than an email stating that I would not be refunded the money unless my application was rejected.

I gambled and got away with it relatively unscathed. There's no way though that an exorbitant good faith deposit should be legal.

shredprez · 2 years ago

A good-faith deposit equal to a typical broker’s fee is WILD, very glad the unit worked out!

Pitchfork is not dead ass now but close. 15 years ago we were in lockstep. I find Gorilla vs Bear best of playlist retains that OG Pitchfork vibe the best.

Is that available on spotify? I desperately check gvb every six months or so, but it seems like a husk at this point
