       | 2. Plowing through the "AI Agents in Action" book. I'm just
       | wrapping up the section on AutoGen and about to move into crew.ai

       | 
       | 3. Reading a book on Software Product Line Engineering.
       | 
       | 4. I have an older project that's Grails based that I let linger
       | without any attention for a really long time. I'm working on
       | updating it to run on the latest Grails and Java versions and
       | also writing some automated smoke tests.

       | Inspired by MathAcademy, I'm developing:
       | 
       | 1) a note-taking workflow in Obsidian (you take bite-sized notes
       | about a topic, then connect "prerequisite" notes in Obsidian's
       | canvas editor)
       | 
       | 2) a tool that uploads each note and graph data to a database
       | 
       | 3) a webapp that presents those notes algorithmically using
       | spaced repetition. This enables you to allow others to "traverse"
       | your note graph in a guided and self-paced manner.
       | 
       | You can add "challenge presets" to each note so that your mastery
       | of each piece of knowledge can be tested with simple flashcards,
       | multiple choice, free response, or some visual/actionable task to
       | force active recall. An algorithm uses your success rate and
       | spaced repetition data to introduce & drill more advanced notes
       | into your long term memory.
       | 
       | Here's some more reading I was inspired by:
       | 
       | https://www.mathacademy.com/pedagogy
       | 
       | https://www.justinmath.com/individualized-spaced-repetition-...
       | 
       | Even if there are a lot of imperfections and flaws about this
       | project (like the sheer difficulty of curating a good knowledge
       | graph to begin with), I'm hoping to make my note-taking in
       | Obsidian more structured and thorough, replace my Anki routine,
       | and make any of my notes into an automated + algorithmic course.
       | If someone has another similar project (combining note-taking
       | with hierarchal, topological knowledge graphs with spaced
       | repetition and testing all in one platform) I would love to hear
       | more about your approaches. Quick shoutout to one person I've
       | seen who is doing something similar:

       | Free Resume Builder
       | 
       | When I was looking for a job last summer, I got frustrated with
       | the current resume builders on the market and decided to build
       | one exactly how I wanted to use it.
       | 
       | - No signup, no login, and no payment.
       | 
       | - Suggest a professional summary (with highlighting) to match a
       | job description [0].
       | 
       | - Preview as you go.
       | 
       | - ATS friendly templates.
       | 
       | - Find relevant jobs for my resume.
       | 
       | [0] Recruiters skim through resumes, and highlighting the
       | keywords they look for has always helped me to get their
       | attention, so I decided to implement this feature using AI.

       | something around it.
       | 
       | So I put together a simple Digital Asset Manager (DAM) where:
       | 
       | * Images are uploaded and vectorized using CLIP
       | 
       | * Vectors are stored in Lance format directly on Cloudflare R2
       | 
       | * Search is done via Lance, comparing natural language queries to
       | image vectors
       | 
       | * The whole thing runs on Fly.io across three small FastAPI apps
       | (upload, search, frontend)
       | 
       | No Postgres or Mongo. No AI, Just object storage and files.
       | 
       | You can try it here:

       | Or see the code here:

       | 
       | Along the lines of predictionbook, metaculus - something that
       | helps you be "well calibrated", but more playful/fun than
       | metaculus.
       | 
       | It doesn't have a lot of upside - predictionbook actually went
       | offline due to lack of interest. But it was a good excuse to try
       | out some vibe coding, and learn react native (I've mostly been a
       | backend programmer).
       | 
       | In an attempt to make it more engaging and fun, I decided to have
       | it focus on sports picks. Also partly because calibration graphs
       | need to have a _lot_ of predictions to yield any reliable
       | information about your calibration.
       | 
       | I got it up in time for March Madness and about 25 of my friends
       | joined and it was a good time. I nagged and reminded them a lot
       | about about 15-20 of them predicted all 63 games, by picking the
       | winner of each match and what their percentage confidence was. I
       | had a leaderboard and live-blogged and gave silly awards.
       | 
       | I later added support for multiple "tournaments" and currently
       | have tournaments going for NBA Playoffs and NHL Playoffs, but
       | interest is waning. Of my friends, only 2-3 others are still
       | regularly predicting.
       | 
       | Maybe it'll be more fun for the NFL season but I might also let
       | it go a bit dormant.
       | 
       | Biggest challenge is that there isn't really a bulletproof way to
       | rank people if people only predict _some_ games in a tournament.
       | I 've tried all sorts of things, minimum # of games, bayesian
       | kernel smoothing, but it's ultimately arbitrary when choosing how
       | to penalize someone for not participating.
       | 
       | If I were to continue I'd be looking at things like automatically
       | integrating with sports apis and odds/bookmaking apis, allowing
       | users to create their own tournaments, etc. But ultimately, the
       | UX of the site isn't much more than making a prediction, and then
       | checking back later when the game is over to see your score. Not
       | much more reason to hang around on the site than that.

       | Since I had so much trouble managing my entire digital
       | information universe [1], I decided to scratch my itch and solve
       | it for myself and maybe others as well. Here are my ideas about
       | my product:
       | 
       | - Manages the entire range of personal (and maybe business)
       | information/content: Documents, Media, Messages (email, instant,
       | etc.), Contacts, Bookmarks, Calendar, etc.
       | 
       | - Is tag based, so that where to put and find content is easy to
       | answer. Think of a set of flat folders, on one or more devices,
       | within which the files are stored with tags attached. Since
       | people often find navigating/browsing files more natural than
       | searching, virtual folders will be dynamically generated to guide
       | navigation. Also, entire folders can be treated as atomic, and
       | tagged/managed as one object (useful for repositories &
       | projects). And, heuristics (and maybe AI) will be used to
       | automatically tag files when they are imported into the tool,
       | greatly reducing the tedium of adding tags.
       | 
       | - Is file based, so that all information is physically stored as
       | individual files. This allows information to be more easily
       | managed on a physical level: moved around, backed up,
       | exported/imported, searched, navigated, etc. So in addition to
       | docs, each email/instant message, contact, scheduled task/event,
       | bookmark, etc. would ultimately be stored as a file, unlocking
       | all the things you can do with files.
       | 
       | - Has a local web-based UI launched from a local agent, so actual
       | file content does not usually need to move across the network and
       | stays local, and the tool is also easily multi-platform, with
       | consistent UI irrespective of platform.
       | 
       | - Provides a cloud web UI as well, that communicates with content
       | devices through the local agent, so that content stored across
       | multiple devices can be managed in one central location, even
       | without direct access to those devices, team/org features can be
       | provided. However, file content still stays local, except when
       | shared.
       | 
       | - Provides tools for exporting data as file from the data islands
       | of various apps and service, and backing up as files to cloud
       | storage services.
       | 
       | My vision is a situation where I am in charge of my own data
       | irrespective of whatever device, app, or service I use, can
       | ensure that it is always available and will not be lost, and that
       | I can easily navigate and search through it all to find whatever
       | I want, no matter how scattered and massive it is.
       | 
       | [1] Here are some of my issues with personal information
       | management affordances of current tech, which is driving me to
       | work on a solution:
       | 
       | - Our data is too bound to device and vendor islands. Can't
       | easily move my information across Apple/Google/Whatsapp, etc
       | accounts. Can't easily merge and de-duplicate either. I almost
       | always somehow lose data whenever I have to move to a new phone,
       | etc.
       | 
       | - Hard to own your data on many services: Discord, Slack, etc.
       | Can't easily export, search.
       | 
       | - Hard to have a 360 overview and handle on all your data assets
       | and query them in a consistent manner.
       | 
       | - Files as a unit of information storage and management is very
       | ergonomic; we shouldn't allow that concept to be buried by
       | vendors for their own gain.

         | - When they make mistakes, the mistakes tend to be different to

         | 
         | So it translates with the top 4-5 models based on my research,

         | 
         | It's more expensive than any one model, but it isn't super

       | spawned several interesting side quests. For example, the backend
       | is in Swift (as I started as an iOS dev) so that has been an
       | exciting space to work in.

       | 
       | For older kids I've been making it easier to write games in Godot
       | using TypeScript:
       | 
       | https://breaka.club/blog/godots-most-powerful-scripting-lang...
       | 
       | I'm building tooling using this technology which allows kids to
       | create their own games, this is itself presented as a game kids
       | can play through. Basically, imagine if Roblox actually delivered
       | on its promises to kids.
       | 
       | Most of what we're building will be open sourced, so that older
       | kids / young adults will be able export their projects and share
       | their creations stand-alone.
       | 
       | Of course, telling kids they can create their own game is only
       | relevant is kids want to do that. We're not locked into one way
       | of thinking. We've also modified Overcooked 2, a traditionally
       | co-op game and introduced a visual scripting platform which
       | allows kids to code their way through levels:
       | 
       | https://www.youtube.com/watch?v=ackD3G_D2Hc
       | 
       | Overcooked 2 won't be the only game for which we do this.
       | Introducing coding to existing games is a fun way to teach kids
       | to code, without yet burdening kids with too much creative
       | freedom. Kids already want to play these games, so this approach
       | allows us to bring educational tooling to kids rather than vice
       | versa.

       | I used to be Head of Engineering at Ender, where we ran custom
       | Minecraft servers for kids: https://joinender.com/ and prior to
       | that I was Head of Engineering at Prequel / Beta Camp, where we
       | ran courses that helped teenagers learn about entrepreneurship:
       | https://www.beta.camp/. During peak COVID I also ran a social
       | emotion development book subscription service with my wife, a
       | primary school teacher.

       | Now that Claude 4 is out, I'm making some updates to the project
       | I've built primarily just with Claude Code:
       | https://github.com/mwalkerr/BookmarkCanvas
       | 
       | It's just a basic IntelliJ plugin which provides an infinite
       | canvas to add code bookmarks to. I work on a large code base and
       | often have to take on tasks involving lots of unfamiliar areas of
       | code and components which influence each other only through long
       | chains of indirection. Having a visual space to lay things out,
       | draw connections, and quickly jump back into the code has been
       | really helpful
       | 
       | The canvas and UI is built using Java AWT since that's what
       | IntelliJ plugins are built on, but it occurred to me that I could
       | just throw in a web view and use any of the existing JS libraries
       | for working on an infinite canvas. React Flow has seemed like the
       | best option with tldraw being what I'd fallback to.
       | 
       | But then.. if the canvas is built with web technology then
       | there's no reason to keep it just within an IntelliJ plugin vs
       | just a standalone web app with the ability to contain generic
       | content that might open files in IntelliJ or any other editor.
       | I'm pretty sure the "knowledge database on a canvas" thing has
       | been done a number of times already so I want to also see if
       | there are existing open source projects that it'd be easy enough
       | to just add a special node type to

       | I analyzed 7 years of Armorgames.com data (999 games) to
       | understand web gaming market trends.
       | 
       | Key findings that might interest fellow developers:
       | 
       | User standards are rising: Average ratings dropped from 7.02
       | (2018) to 6.45 (2025), but the percentage of high-quality games
       | (8.5+ rating) actually increased from 12.3% to 14.7%. This
       | suggests quality polarization rather than overall decline.
       | 
       | Genre trends: Rising: Idle games, Strategy, RPGs (deeper gameplay
       | mechanics) Declining: Traditional arcade/action games Stable:
       | Puzzle and Adventure (web gaming staples)
       | 
       | Innovation wins: The highest-rated "hidden gems" all had one
       | thing in common - innovative mechanics rather than genre
       | variations. Games like "Detective Bass: Fish Out of Water" (9.3
       | rating) and "SYNTAXIA" (9.1 rating) show originality still pays
       | off.
       | 
       | Market maturation: The correlation between rating and popularity
       | is surprisingly weak (0.126), suggesting quality [?] virality.
       | However, play count strongly correlates with favorites (0.712).

       | I just shipped a camera app for iPhone dedicated to Bayer RAW

       | noise reduction, etc).
       | 
       | https://bayercam.app
       | 
       | I had fun with the interface - it's themeable, and inspired by
       | classic cameras: lets you quickly switch between full auto/half
       | auto/full manual modes with dedicated dials.
       | 
       | Going to add more features in the coming months, but the #1 focus

       | 
       | Given that virtually all processing pipelines these days stack
       | multiple shots to create a photo, as far as I'm aware this is the
       | only way of getting a "traditional" single-exposure photo on
       | iPhone, where the shutter speed is actually meaningful.
       | 
       | There are other camera apps that support Bayer RAW capture, but
       | those support a bunch of other formats, and you probably don't
       | want Bayer RAW for most of your shots anyways, so for my own
       | workflow it's better to have a dedicated app that I can launch
