John Marc @ioloro.bsky.social · 27/07/2026The past two years I've made it out to Hala Kahiki with a small group from the conference. Great convos and beverages. 011
John Marc @ioloro.bsky.social · 18/07/2026Know it's little ol' me, but I just hit 1000 tickets created in Linear for @dewygolf.bsky.social; I'm astonished at the amount of work I've put in. 010
John Marc @ioloro.bsky.social · 03/07/2026Just booked my @deepdishswift.com ticket and so excited to attend again in 2027. 040
John Marc @ioloro.bsky.social · 24/06/2026Part of building out @dewygolf.bsky.social is building a process and task management system that is flexible, able to work on multiple machines/droplets. Seeing the system churn on ~40k golf courses has been rewarding and very excited to see new courses come "on line" daily. 010
John Marc @ioloro.bsky.social · 19/06/2026I’ve optimized the map collection process to the extent that what was initially expected to take 30 days for the entire USA can now be completed in less than 2 days. Still have more processing/learning to go, but most courses no longer need human intervention to create, understand and validate them 030
John Marc @ioloro.bsky.social · 18/06/2026@dewygolf.bsky.social continues to build out the v1 maps. Looking at this one honking course in Florida I'm excited by the results and the future of golf maps. All that hard work is starting to show up and cannot wait for what's next. 000
John Marc @ioloro.bsky.social · 17/06/2026If you’re in the Boulder area this evening, there’s boulderOS @ 7. Also fun is that it’s on Apple’s Community Events page. More information: boulderOS.com 000
John Marc @ioloro.bsky.social · 13/06/2026Got my first (only) 1 star review because they don't want to pay for an app. Think this is the correct way to respond... 220

John Marc @ioloro.bsky.social · 24/05/2026This morning, I had a meeting with my sister to discuss a new project she needed for a thesis/class work. (She’s a nurse; I'm not) I quickly used @heygenai.bsky.social's Live Avatar to create a mockup of an experience and test the idea. About 2 hours of work and up and running. 000
John Marc @ioloro.bsky.social · 23/05/2026Wild seeing Brazil/Portuguese overtake US/English for one of my side projects. Localization matters because people being comfortable in the app they use matters. 000
John Marc @ioloro.bsky.social · 19/05/2026Printing my v1 model for @dewygolf.bsky.social maps. Really jazzed to see the numbers improve and all the hard work (hopefully) pay off with clean results. 010

John Marc @ioloro.bsky.social · 12/05/2026Cont. adventures in annotation. Playing with "ISpy" (don't sue me), where each annotation has it's own frame (crop is user set) can filter on confidence level and then you're off checking "is/is not". Been pretty fun. A few standard of living enhancements like hide/unhide and zoom. 020
John Marc @ioloro.bsky.social · 03/05/2026Up early further refining my CV/scorecard parsing model. Hot Chip's In Our Heads is an excellent playing partner for that task. 000
John Marc @ioloro.bsky.social · 03/05/2026As I get deeper into maps, I keep learning new, cool things about how to represent relationships of items to one another. i.e. golf courses have (typically) 9 or 18 holes, each has a tee box, and green.algorithms.discrete.ma.tum.deThe Hungarian MethodThis page demonstrates the Hungarian Method for finding maximal matchings in bipartite Graphs. 110
John Marc @ioloro.bsky.social · 30/04/2026It might sound familiar from my @deepdishswift.com talk, but being part of or interacting with the community you intend to build apps or services for is likely the most significant advantage you could look for. 130

John Marc @ioloro.bsky.social · 17/03/2026Continued efforts to build out better detection and annotation tools. Using SAM3, creating first pass annotations, then validating before kicking off additional active learning. Created a "swipe" feature set to swipe to approve/reject/skip annotations. 011
