I am working on SpreadsheetPreview.com, a subscription service that gives you PNG previews of your uploaded spreadsheet (xlxs files).

On the server it opens a headless browser, where it converts the XLXS format to OGF (Open Grid Format), which is then rendered by DataGrid Toolkit, the engine behind DataGridXL v4. It then takes a screenshot of this render and sends it back to the requester.

Try out a few renders at https://spreadsheetpreview.com

I'm working on a Personal / Family travel organizer. Started as tool to allow me and SO to plan a trip together. There's been steady progress over the last couple years. Focus on privacy and ability to self-host. Of course, there is a managed version if one doesn't mind me having access to their data.

Interesting! Maybe making this info avilable to local LLMs would be useful too. Side thought: when we plan big trips I tend to pre-populate google maps with loads of markers of interesting points. I would love to be able to save this offline and combine them with other sources like youtube/instagram clips offline somehow.

Been working on https://searchcode.com/ again which I bought back, albeit as code search tool for LLMs. It solves the “should I use this library” by allowing the LLM to inspect search and analyse it before integration. Can use it to compare multiple repositories before downloading. It comes with a large amount of token savings and can be really useful when wanting to learn about a codebase.

Since it does it anyway I added dossier pages to it as well https://searchcode.com/repo/github.com/rust-lang/rust Which is useful for humans, and shows what the system is creating.

Best part is that I get to use the tools I have built, so https://github.com/boyter/scc and https://github.com/boyter/cs to improve it which benefits anyone using those tools.

Since getting laid off in Feb, I've been spending my free time polishing up my word game Gram Jam (https://gramjam.app).

I finally finished the (monumental) Svelte 4 -> 5 migration that had been getting dusty for the last year. This unlocked a higher performance ceiling for me to polish my animations and UX. Now I'm revamping my onboarding experience and taking another crack at marketing and promoting it. Last year, I was focusing on setting it up as a PWA and integrating Sentry monitoring and Stripe integration. All important stuff but not what got me excited about the process.

I've been pretty tied up with maintenance and admin work, and haven't gotten a chance to work on the actual game design in a while, so I'm very excited to return to that part of the project soon. I have ideas for new puzzles and modes spilling out of my ears and I feel like with LLMs my prototyping can finally keep up with my brain, now that I have a robust foundation for the game architecture.

Been writing in my blog every day, reading more, created a poker equity calculator, and working on a city wide project where I document attractions, restaurants, and stays I've experienced in my city (very early stages).

I also created a couple of chrome extensions:

Created a small command line util to get earthquake data in the Philippines:

I am building Akariq which provides data eSIM data plans to 185+ countries and regions across the world. I am 2-3x cheaper than big brands in the same space. I also prefer local data routing i.e. I don't route traffic from US or EU to Hong Kong, they stay in your country / region.

Just curious, I have no idea how eSIM reselling business works: How can you offer 2-3x cheaper prices? Is it because others have very high margins, or because you have a secret optimisation method?

helloakariq 1 day ago||

Great question. Cheaper prices come from a mix of focus on customer value primarily. That includes making sure that the eSIM is high quality (low latency, data routing in the region) and also focusing on getting the best eSIM plan to the customer - transparency, better FUP etc. So there's an element of optimisation involved here.

I got my app in the Mac App Store! It's a layer based image editor, which as a developer has been a nerd's paradise to develop. How should disparate blend modes work with "merge down"? What does it mean to have one color channel selected when you move a layer? Should type layers use their Oriented Bounding Box or their Axis Aligned Bound Box with free transform? So much ambiguity to resolve and I'm loving it.
