#262Working on https://greatreads.dev/ A place to aggregate and find articles from developers' blogs. Right now, I'm building a submission form for people to submit new sources.
There is also a way to search for articles using vectors, it's called "Semantic Search". So basically you can ask, for example, "Postgresql and how to best optimize it." and it would search for articles touching that subject, or at least related to it.
Wondering about the best way I can add a weekly newsletter built on top of the content currently being ingested, and still looking for more sources to add to the database (let me know if you have any good recommendations).

#263I've been working on LLMParty for some months. It is a collection of experiments that use LLM under the hood. For each experiment I tried to play with something different, such interaction, LLM knowledge, use, etc

#264Residential solar PV+ESS w/net metering. Rushing to finish connecting it all for inspection on tuesday... if I'm lucky and get commissioned this year I can get the last federal tax incentives. Fingers crossed

#265https://PostalAgent.com – Send personalized postcards online.
Upload a CSV or circle neighborhoods on Google Maps to build your address list (consumers or businesses). Printing and postage included in one price.
In the last 30 days I've added an API plus integrations for Pipedrive, Zoho, and Follow Up Boss. If anyone wants to help test these new integrations, I'll set you up on a special plan and let you send mail at my cost (roughly the price of a stamp).

#266For the last 3 years, I have been working on a web tool to help me at work: debugging ASN1-encoded data (keys, certificates, Kerberos/CredSSP/SPNEGO/etc data structures, and more) and performing various cryptographic operations. This app is available online; you can try it [0] (no sign-in/up needed).
This December, I reached a huge milestone: I implemented ASN1 tree editing [1]. Now I can edit the ASN1 tree directly in the browser (read my blog post for more details: [2]).
I'm happy that I wrote this tool. I use it often to help me debug my protocol implementations and/or debugging. I know that some of my friends use the JWT debugger and ASN1 parser from this tool. Maybe some of you will find it helpful too.

#267I'm building a temperature controlled dough proofing enclosure based on ESP32, an IKEA Samla storage box and an inexpensive silicone rubber heater. It's delightfully impractical-- purely a first hardware/MCU learning project and a holiday gift for a relative who I think will appreciate it.
I'm impressed by how far I can get "vibe making". Most of my professional experience is in high-level software, but AI gets me unstuck quickly when I don't know something specific to ESP-IDF or the hardware. As of today I've got a circuit tested, firmware nearly complete, and a custom PCB en route from JLCPCB.
One limitation I’ve noticed: ChatGPT struggles with the details of part selection (e.g. choosing specific temp/humidity sensors or connectors). Adding datasheets to the context helps a lot, which makes me wonder why this isn’t something the model can do or at least ask for.

#268I'm working on WishKeeper https://wishkeeper.io.
It's a webapp that lets you create wish lists and share them with family and friends. The key feature is the claim system: when someone decides to buy you an item, they can claim it so others know it's taken, but you never see who claimed what or even that it was claimed at all. The surprise stays intact. You can also split big purchases. If someone wants a $400 stand mixer, multiple people can chip in allowing family tight on cash to feel like they're contributing without having family members feel like they have to put small items on their list just so everyone can contribute.
I kept it deliberately simple. No social features, no feeds, no ads. Just lists with items, links, prices, and notes. You create a list, share the link, and you're done. No group chat gymnastics required. It's free to use. I built this because I wanted it to exist, not because I had some grand monetization plan. You can sign up and create lists without a credit card.
Suggestions welcome!

#269For a long time I've been looking to solve the repetitive schema pattern issues in SQL. This week I created a DSL that allows parametric polymorphism for SQL, and I wrote a compiler for it.
Source code and playground here: https://github.com/BarishNamazov/gsql/
Background blog here: https://barish.me/blog/parametric-polymorphism-for-sql/
Feedback is super appreciated!

#270A Jellyfin client written in Rust, specifically for music. Most existing clients are electron or web based and I wanted something native.
