I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups. Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those serv…

I'm super interested in this, I'm the developer of Kavita and would love to be able to extract metadata from ISBN from user's files.

Is there a Github/Site where I can follow you (or this project) on?

I'm working on a site that serves as an alternative to Hacker News. There you will find two relevant options (at least I thought so kkk)

1. A notification system. All posts that are commented on or voted on (positively or negatively) will generate notifications on the site for the owners of the respective posts.

2. Diversity of topics. On Comuniq we're not fixated on a single theme, so users who like topics such as health, politics, entertainment, art, etc. will be able to post there and generate very intelligent debates.

We're not trying to take power away from our monster hn, but rather to provide another option where we can talk about other things we love. Check us out at https://comuniq.xyz

Service isn't online yet, but you can find me on Sourcehut[1] and on GitHub[2], where I'll probably be posting the service soon. You can also email me[3] if you have a request or a specific use case I might be able to support.

Side project: https://healthymcp.com

At work we have an MCP that is mostly a proxy to our API and it was a little tricky to get it hooked into our regular CI/CD regression testing so I thought a dedicated service to track MCP server statuses could be useful.

Hacking away at it slowly. So far it has ping monitoring, tool validation, resource checks, SSL and DNS / HTTP header tests

Hoping to get protocol version logging, custom tool-call monitoring, response schema tracking in relatively soon.

Currently a one-man side project: https://laboratory.love Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe. This seemed like a solvable problem. Laboratory.love lets you crowdfund independent testing of s…

Wow, great idea, simple website and hopefully a positive impact, not often you see all three in one project :) Good job! I'm guessing it's limited to US products and US labs? Would love something similar in Europe and/or EU, but it isn't clear if you're limited to US/North America right now, would be nice if it was a bit clearer up front :)

Yeah, I should add something about this to the FAQ page, thanks for pointing this out.

I'm not technically limited to US products, but I can (currently) only test products that can be shipped TO the United States.

I suggest you xpost to Bryan Johnson's Blueprint community. I think might help you get a lot more food tested. That community is probably ICP and also can amplify the message.

Folks at Blueprint actually reached out to me when they saw this project at the beginning of the year and essentially tried to acquire it by hiring me as a contracted engineer. I politely declined.

Blueprint Quantified, which is linked in the below comments, went live after these conversations. Imitation is the sincerest form of flattery.

Wow! I'm a food&bev founder and absolutely love what you are doing! How can I submit my products for testing?

Products can be submitted anytime here: https://laboratory.love/add-product

It just needs to be a product that's available for purchase.

Love this! But I’m struggling to understand the results

Yeah, I will be doing some work to make the results more interpretable.

Jacobin, a JVM for Java 21 written in go Website: https://jacobin.org GitHub: https://github.com/platypusguy/jacobin

Cool! How far are you planning to take it? Interpreted mode only? Or do you plan on going the whole HotSpot nine yards with compiling bytecode down to native code?

Sorry for the delay in replying.

We want to complete the interpreter and then decide what to do moving forward. The two principal options (and both might be followed) are 1) performance and 2) a separate UI that connects to Jacobin via Websocket or other protocol and enables display/observation of JVM instructions as they're being executed (and of course many of the other observable events).

The biggest hurdle we've faced is the vast number of native methods called by the HotSpot JVM, which need to be reproduced in go for a go-only JVM. I think we've spent as much time working on the native methods in the various libraries as we have on the JVM proper. By our analysis, the JVM calls a total of 1800 native methods. Many won't be needed by us b/c we use go's garbage collector and we don't implement the security manager (which Oracle is deprecating)--but that still leaves quite a few.
