There are many tells aren't there? There was clearly hard human work and experimentation here, but it's a shame the OP let AI do chunks of the writing. Once you see it, it's much harder to take the post seriously.

Show HN: CoreMem – Portable context for AI agents

20wenty — Fri, 22 May 2026 17:52:35 +0000

CoreMem lets you build collections of context, called a mem, and share it with any AI agent via URL, a Chrome extension, MCP, Cursor/VS Code plugins, a skill, and more. Instead of re-explaining your project or goal when you switch agents or start new sessions, CoreMem keeps your context centrally organized so that any AI tool can read it.

This originally started as a CLI I built that kept pieces of context (Project A/B/C details, my writing style, preferred tech stacks, coding style, etc) in a SQLite database. I could instruct various agents to “use my `coremem` CLI to retrieve details about [project A] before we get started.” It solved a problem for me b/c I am continually bouncing around between different projects and chat agents, and having to re-explain myself every time became an exercise in either repeating myself or copy/pasting summaries I’d saved from previous sessions.

I decided to make this a little more robust and portable, so I turned that original CLI into a SaaS. Tl;dr: You can create a “mem”, which is a collection of 1 or more pieces of related context, and share that mem with any agent to quickly get them up to speed.

Right now I’ve got integrations in the form of revokable share links, a Chrome Plugin, Cursor Plugin, Cursor/VS Code extension, Claude Code plugin, ChatGPT/Claude/Gemini/et al via MCP. Since I mostly work from the CLI, I use the Claude Code plugin or create 5-min share links I can drop into a chat, but I’ve tried to make this useful to people who mainly work from a browser or an IDE.

I’ve been coding for 30+ years, and I vibed most of this. I was able to use CoreMem to help it built itself as I jumped between various coding agents, having them grab context then start a new task. I’m sure my architecture and engineering experience helped, but building this in a few weeks confirmed for me that the barrier for someone to build a tool they need to solve a problem is incredibly low.

The rush I used to get from coding has mostly faded, but I’m getting similar rushes managing different agents to build things now.

"Google has made it really easy to create api credentials for own use, just follow these few steps..." As someone who's been through that particular gauntlet a few times recently, I got a chuckle from the sarcasm.

I second this -- I just found the Ben Eater series a month or so ago and put together his computer clock over the holidays. It really helps you understand clock cycles, logic chips, etc, and is a good foundation for the 6502 kit you build later in the course. And learning Assembly before BASIC is the right learning path IMO, if only to understand how CPU registers work at the electron level.

Show HN: I wrote a Christmas-themed Space Invaders clone in 8086 Assembly

20wenty — Wed, 24 Dec 2025 15:21:50 +0000

I've had a goal for the past three years to learn Assembly language. This December, I finally put some real effort into learning the language. I followed the tutorials in Oscar Toledo G's "Programming Boot Sector Games" and used Gemini as a tutor to help explain the concepts I was stuck on. It was tempting at points to vibe code some of the trickiest pieces, but I found resisting the temptation and using Gemini just to be an expert tutor to answer my ignorant questions brought back the joy of coding again. The result is a Christmas-themed Space Invaders clone written in 8086 Assembly.

The code isn't perfect, and neither are my line-by-line comments, but it's a good exercise if anyone else is trying to learn a language.

The game compiles to a .com file and runs in DOSBox. I'm not trying to fit it into a boot sector (512 bytes) like the original tutorial (https://github.com/nanochess/Invaders/blob/master/invaders.a...), so my code assembles to more verbose (around 700 bytes).

I have never made it to the end of a Wolfram post, or a David Foster Wallace book. I'm envious of people who can read AND understand these tomes.

Yeah it's confusing. They mention https://registry.modelcontextprotocol.io but it is just a redirect to https://github.com/modelcontextprotocol/registry/tree/main/d.... Like MCP itself there's still work to be done, it seems.

Do you have details on what "optimise for token usage" looks like in Cursor? Or is your point more about how Cursor manages the context window?

Thank you, thought I was going crazy. Maybe this is the new thing, adding grammatical errors so people won't think the content was written by AI.

If it gives any unfair advantage at all, the Astros will figure out a way to use them ASAP.

I like the idea but it will be hard to build a moat -- if that's something you care about. How about making it more general? "touch grass", "feel sand between your fingers", "hug a tree" ...

The damage is done. You can't overthrow the king (whether you pledge fealty to iTerm2, PowerShell/WSL, Putty, Hyper ... ) if you have to sign up to get past the castle gates. And in the two years it took to remove the signup, the townsfolk have realized their kings are good enough for what they want to do anyway.

Same opinion on 1Password's great service. I've found them to be responsive and accessible anytime I've needed them. I'm not seeing all the bugs and issues others are reporting, but I have noticed a couple of odd UI changes lately that feel a bit like a product manager is bored and looking for work to do.

For the most part this post was easy to read, and I could feel the collective excitement of the team. I came away feeling like I'd learned something and ready to try it myself. The only time the post gets a little fuzzy is "...store the quantized parameters in a selectable data type, where that storage data type is the same data type as the “computation type” of the mode". I assume "selectable datatype" is the float size of the quantization?

This is like looking at a painting and thinking "what's the big deal, I could paint that." I'm guilty of the same, and yet, I've never painted.

You're not necessarily wrong, but you may also be throwing stones from a glass (Substack) house. Barely made it past the fold before I was nagged with a Substack popup.
