I've been working on an offheap allocator for Go.

In contrast to the popular arena based allocators (which target quickly allocating/freeing short lived per-request allocations), I am targeting an allocator for build very large in-memory dbs or caches with almost no garbage collection cost.

There's a little no-gc string interner package in there as well.

https://github.com/fmstephe/memorymanager

It's somewhat on pause right now as I have just started a new job. (but it has been a very fun project, nerdy joy).

Related to the memorymanager, as in intending to support it are

https://github.com/fmstephe/fuzzhelper A library for setting up fuzz tests for complex data structures.

https://github.com/fmstephe/gossert A library for adding runtime assertions to Go code. It's developed so that when the assertions are switched off the compiler should be able to completely eliminate the assertions. But this requires build tags to switch the assertions on.

I'm working on Finzz; I like investing but was struggling with doom-scrolling across various platforms to find things that were relevant to me. So I created Finzz which on-demand creates a multi host audio podcasts focused specifically on my stock portfolio and investment goals. I tell it the reasons behind why I hold these stocks and it tries to keep me honest to these goals and suggest rough actions from time to time.

Here's a sample if you are wondering what its like: https://finzz.xyz/shared/rnl-oO955IPZN6Ux78E-l8DC

I’m working on Karl [ https://www.veloursdevices.com ], a MIDI controller. It’s quite unique because it features 32 encoders over a display, which allows you to have a fully customizable interface—like a touchscreen, but with actual knobs you can touch. I have a software engineering background, and I’ve been working on this for nearly 3 years now! I used to play with the Electra One controller before, but having the…

Wow! Never seen "encoders over a display" before. This could be revolutionary in so many different scenarios beyond MIDI controllers. First scenario that comes to mind are car user interfaces. Mixing screens with physical controllers is such an innovative idea. Thanks for sharing.

https://finalefeline.com I'm developing a small community focused on rating TV show endings. I've grown tired of investing time in series that get canceled and end on cliffhangers. Unless the show is really good, and even then, I prefer starting knowingly.

Curious how "Lost" scores on the scale of endings. It's not a cliffhanger and it didn't get cancelled but...

I've been trying to put the finishing touches on my daily word game Omiword (https://www.omiword.com/), but I've been waylaid by Stripe because they decided that a simple daily word game is a "restricted business," and they shut down my account.[1]

Now I need to figure out an alternate payment handler, or just give up on my modest monetization plan where players can pay a small one-time fee to unlock all of the archived puzzles. It was never going to make a fortune, but it would have been nice to offset some of the hosting expenses.

Don't use Stripe. They shit on you just because they can.

I am working on an agent that can tutor you in introductory physics. Beyond being a chatbot, it can summon and mutate several kinds of diagrams and graphs to teach concepts like kinematics, energy, momentum and hopefully much more down the line.

Here’s a very early version for circuits: https://www.circuit-tutor.xyz
