#182I am busy rebuilding my music studio with only gear from the late 90s/2000. It's much more fun to relive my youth and with patience less expensive than I thought.
Oh those were golden years in the studio, hope you have a lot of fun.
Just casting my mind back to the setup we had in '99:
Juno 106, Korg Monopoly, TX816. Prophet 5, Seq Circuits Pro1, Novation bass station, 909, Korg Wavestation (rack), Korg M1, EMU sampler (EIII rack IIRC), Atari Mega 4 + Cubase for seqs, a IoMega zip drive for storage that killed every other project with click of death, and fucking midi cables and audio snakes running everywhere... great days.

#183I'm currently working on a new blockchain technology called Roughchain. Earlier today, I shared the whitepaper in this HN thread [1], and I’ve already received some valuable feedback.
The core architecture is split into two components: a timestamping signing service and a P2P gossip network. By decoupling the gossip network, I'm simulating its performance using a Monte Carlo approach. With a basic gossip protocol, the simulation reaches ~10k TPS on a 100-node, randomly connected network (not fully connected), and I see a lot of potential for further protocol optimizations.
Initially, I considered a more resource-intensive approach using Shadow [2] for more realistic node simulations, as outlined in this discussion on libp2p's Gossipsub stress metrics [3]. However, the Monte Carlo method allows me to simulate the network more efficiently without needing to deploy full nodes.
In parallel, I'm exploring game-theoretical concepts for selecting signers and ensuring the system remains open to new entrants. One paper I'm currently diving into is "Collusion, Efficiency, and Dominant Strategies" [4].

#184I'm working on https://www.ironcalc.com as a side project.
A spreadsheet engine with an open source permissive license. I have high hopes for it but I'm still in early stages of the project.

#185I've been working on https://wut.dev in my spare time. It's essentially a simpler, read-only, AWS dashboard where everything is a filterable, searchable, exportable-to-CSV table, with some extra features like multi-region mode, saved notes, and a debugger for access denied errors. It uses the AWS SDK for JavaScript, so everything is run client-side from your browser. I'm not 100% sure what direction I'm taking it yet…
are you designing the UI for every service by hand, or doing it programmatically somehow?
Thankfully programmatic. It’s a common UI table widget, essentially, and I’ve written some custom code to handle multi-region support, updating the AWS credential handler, pagination, and response processing. From there, it’s a matter of plugging in some common options for each AWS service: the service name, SDK method to call, pagination property (annoyingly, AWS API has numerous ways of paginating responses), etc. Takes about five minutes to add a new service.

Ohh this is awesome! Thanks for sharing! How much time per week do you work on something like this?

#187I spent a week building a website that is a repository of timeless content. It generally consists of old magazine articles (though not exclusively) that you can pick up at any time and will bring value to your life. I notice most of what we consume on daily basis is ephemeral and not all that valuable outside of the moment, whereas ever-present content is always valuable. The unique angle here is that each article in…
From that I’m guessing you don’t want to open it to random HN folk, but if you ever do, it sounds a great resource and something I’d love to participate in.
For anyone that wants access just shoot me an email (it's on my HN profile).

#188Working on validating a startup idea I had 12 years ago. It's like Pingdom for ads, periodically checking if your ads are being blocked by AdBlockers. I always thought the idea was somewhat weak, but not enough to discard entirely. So, along with a friend, I built a prototype over the last two weeks, and now we're trying to validate it: https://scanningfox.com/ I'm enjoying using Elixir for this project. As a long-ti…
Liveview is so much fun. I want to build more things with it.

I work a little bit on it every day. I guess somewhere around 15 hours per week. Glad you like it.

#190My primary project the past couple weeks has been applying the AI interpretability technique from Anthropic's famous paper this past summer (you know, the Golden Gate Claude one) to single-cell RNA-seq data. What works on one huge, inscrutible vector space ought to work on another, right? In either case, a fun way to keep in practice, both for comp bio and deep learning. My side-project, in essence, the bash '&' oper…
I may be misunderstanding what you're trying to achieve, but you can simulate the bash '&' operator for a running process by pressing ctrl-Z to suspend the process and send it to the background, then running 'bg' to continue the process in the background.
