Hidden input fields are input too and require the same level of server-side scrutiny ... "hidden" does not mean safe to use as-is.

Switched from ASPNET MVC to Razor Pages ... lighter and the code that tends to change together is closer together.

I've been slowly tapping into more and more MCP servers for the front-end work I do. The output is stable by design (the irony) for a lot less tokens.

New post: Event-sourced Claude Code Workflows This is an experimental / proof-of-concept follow-up to my previous posts about Claude Code workflows. Blame @yves.reynhout.be nick-tune.me/blog/2026-03...

Iconify MCP if you are into icons.

The ability to move a computation from the query side to the projection side for charts has been invaluable both in reducing the amount of recompute but oddly also in the amount of storage needed.

Inline chart.js data delivery in ASP.NET MVC is now another trick up my sleeve.

Just had a phisher trying to scam me … wishing them better luck next time 😂

House of Cards, late to the game, but here we are.

ContextFlow is now multiplayer. Share a URL, edit the same context map in real time. No account, no setup. Projects sync to the cloud automatically. Also new: drag-and-drop team assignment, DDD tooltips on every canvas element, and a visual color legend. Free OSS: contextflow.virtualgenius.com

Waiting for the “oh noes, my LLM is down!” much like “my hosted git provider is down”.

I got fed-up with the primitive-obsessed way ASP.NET handles forms as a model, its take on validation and the sprinkled attributes. Inherently HTML form input is a collection of strings, so I stopped pretending. I created a small library that embraces composition, allows me to set

Working with Agents is just mob programming with very apologetic co-workers.

Always amazed by the speed of duckdb.org on top of parquet.apache.org (and by extension github.com/aloneguid/pa...)

One of the challenges I've been tackling lately is to create immutable sets of data that serve both display and calculation purposes. Traditional historical data modeling (using either history tables or history rows) are not particularly useful, given that it's really about the "set" at the point in

I've been using a lot of classic MVC lately. HTMX is what is making it enjoyable and reduces JS to the bare minimum. The SSE extension is icing on the cake: htmx.org/extensions/s... - all node-less, npm-less, spa-less, ...

One of the recent features of KurrentDB is its ability to perform docs.kurrent.io/server/v26.0.... What is overlooked is that it's an easy way to enforce set-constraints, one stream governing the set, the other stream governing the specific entity that wants to claim its place in the set.

Dad jokes be like …

One thing that's really a sore spot in event sourced systems is bringing in "data" from a legacy system. Most implementations I've seen seem to drop down to the technical level: summary events with "Imported" in their name. I don't have a good answer to this myself. State based systems don't have

Been using AI to both detect and fix a lot of data quality issues in historical data. Targeted, useful, which gets me to roughly 90% of the journey.

Winter 🤷‍♂️

The pendulum of message abstraction is an under discussed topic.

There are a lot of nice attributes to classic ASP.NET MVC, but the way it handles validation and errors sticks out like a sore thumb. Luckily, you can work around that.

Really appreciated your talk @maartenballiauw.be on Htmx (www.youtube.com/watch?v=Nkog...) as well as @khalidabuhakmeh.mastodon.social.ap.brid.gy 's work on github.com/khalidabuhak... - came in handy at just about the right time.

It takes creative thinking to design a system backwards. I've often started somewhere smack in the middle of things, honing in on the core / complexity. But incrementally back-tracking to the very beginning of a flow, that's a first (this isn't about outcomes, mind you). Constraints like this cater

Blind Sherlock was not worth the watch.

Steal (Prime) is well worth the watch.

I've been treating my MVC more like my MVU.

My modus operandi seems to be that whatever project I’m on, I live and breathe it. Deep entrenchment, hoping for new insights along the way, aka the reward.

A pattern I found useful in calculation heavy domains is to report intermediary results as part of the computed result, making it easier for end users to verify them, as it ultimately embodies a developer's understanding.

Finished The RIP and season 1 of The Peripheral.

Creating a visual DSL to represent inputs, calculations, rules, computed outputs (intermediate or final) as a DAG. Was looking for prior art of Visual Excel but could not find it.

One of the harder problems in design is whether to remain specific or to become abstract. It's easy to see what it should have been in retrospect but near impossible to forecast. Making the wrong choice causes extra labor in a lot of places. Being specific usually means more typing, more code.

Somebody already made "is claude down or is it me"?

jsonquerylang.org ♥️ the simplicity

Integrating with 3rd party systems in your own system comes with its own challenges. Fundamentally, there's a choice on the table of how deeply one integrates, how much of the integration language we allow to rub off on our own. In my experience, the answer is very context specific and often boils

Knowledge crunching in a legacy context with a lot of manual tribal rituals is something else. My modus operandi is to attack the problem space from many different angles to form a mental picture and instill common understanding. Then, partitioning one flow at a time, iterating in each compartment,

Venturing into a new domain, a recurring model "candidate" is "simulation". The ability for end-users to try something before deciding on something, a small loop of multiple drafts before committing to an outcome, is perceived as valuable.

My beef with "modern" design and modeling techniques is that they've become the center of attention, not in the least by their proponents. If you can't concede that it is a means to an end and that what you are modeling is more important than your petty modeling technique, than I have no use for it.
