Fuzion May update: In April, an important issue with effects was solved: Where do default instances come from? A big bang singularity that instates them when the system starts! And an effect wormhole passes effects on to other threads. The details: fuzion-lang.dev/news/news_062

The Fuzion language April update is out. A focus of the current work on Fuzion is stabilizing the code base, removing engineering debt and fixing bugs while preparing for the development of real-time APIs through tool and API support. All the details: fuzion-lang.dev/news/news_061

The Fuzion language March update is out. Putting Fuzion code in production by switching to fzweb as the webserver behind fuzion-lang.dev is the biggest step ahead. A number of optimizations and base lib additions supported this step. All the details: fuzion-lang.dev/news/news_060

A major milestone for the Fuzion language has been reached: fzweb, the Fuzion port of the web server behind fuzion-lang.dev, has gone live earlier this week replacing the Java-based webserver. fzweb is, of course, also open source and available on github: github.com/tokiwa-softw...

The Fuzion February news are out! We are focusing our work on exciting performance improvements and cleanup work towards the Go Live of fzweb, a re-implementation in Fuzion of the web server behind fuzion-lang.dev. fuzion-lang.dev/news/news_059

The Fuzion January news are out. Improvements include new syntax for anonymous inner features and a number of performance enhancements and code cleanup. All the details: fuzion-lang.dev/news/news_058

#AdventOfCode Dec 12's puzzle in @fuzionlang.bsky.social: First thought this is impossible and put it aside, but the input data is so simple that there is no need to check actual present arrangements as long as the total size fits. The sources on github: github.com/fridis/fuzio...

The Fuzion December news are out. Next to many incremental improvements on the Fuzion language, libraries and tools, work has started on a new tool for runtime scheduler monitoring called feeze. All the details: fuzion-lang.dev/news/news_057

#AdventOfCode Dec 11's puzzle in @fuzionlang.bsky.social: I first did not expect simple counting of paths to be sufficient, but with memoization, that worked fine. The sources on github: github.com/fridis/fuzio...

Five days late with my #AdventOfCode solution in @fuzionlang.bsky.social. After part 1 was super easy, I struggled with the shear amount of work for solving the underspecified system of linear algebra equations in part 2. But then I found www.reddit.com/r/adventofco..., a very nice idea... 1/2

Today's @adventofcode.bsky.social in @fuzionlang.bsky.social started with a simple part 1: two lines after input preprocessing and defining a helper feature to calculate the area of a rectangle. Part 2 is more tricky, requires checking if a rectangle is contained in a concave polygon. 1/2

@adventofcode.bsky.social getting more challenging: Today's solution in @fuzionlang.bsky.social declares an orderable feature `pair`, cuircuits are equivalence classes identified by the first box. And reading comprehension: www.reddit.com/r/adventofco... The sources: github.com/fridis/fuzio...

Yesterday's @adventofcode.bsky.social solution in @fuzionlang.bsky.social: arrays used instead of lists to avoid quadratic performance. part2 was simpler than part1... The sources on github: github.com/fridis/fuzio...

St. Nicolas' @adventofcode.bsky.social in @fuzionlang.bsky.social required tricky transposing in part 2. Surprise for me: partial application of operators usually requires '('/')', not here: 'fold1 (if op="*" then * else +)' or even 'fold1 (op="*" ? + : *)'. sources: github.com/fridis/fuzio...

Today's @adventofcode.bsky.social solution in @fuzionlang.bsky.social: Instead of testing all the ways two ranges can overlap, just checking if they are completely separate and joining them if not helped a lot. And there is an existential operator ∃! The source: github.com/fridis/fuzio...

Finally an @adventofcode.bsky.social solution in @fuzionlang.bsky.social on the same day: Using an array2 2 slots wider and higher helps avoid many special cases. A bit cryptic, but convenient: ||>x,y->... defines a lambda on a tuple and destructures the tuple. Source: github.com/fridis/fuzio...

Catching up with this year's @adventofcode.bsky.social, here is a fairly concise solution for yesterday's challenge using @fuzionlang.bsky.social: A recursive function joltage(n,v,l) did the trick for length n, current result v and remaining list l. The sources: github.com/fridis/fuzio...

Still lagging behind with Dec 2's @adventofcode.bsky.social in @fuzionlang.bsky.social: very useful was Sequence's unique feature to remove repeated ids. Source: github.com/fridis/fuzio...

A little late to the show for Dec 1's @adventofcode.bsky.social in @fuzionlang.bsky.social: Went for a simple, fully functional solution using 2 nested folds that perform single clicks of the dial, optimizing this resulted in uglier code with too many cases. Source: github.com/fridis/fuzio...

The Fuzion November news are out. Our base library profits a lot from the work on the fuzion webserver fzweb: added functionilty, better usability and performance! For the Fuzion language, type-safe variadic functions are an major addition. All the details: fuzion-lang.dev/news/news_056

The Fuzion October news are out. We are making fast progress implementing the webserver behind fuzion-lang.dev to Fuzion. On the Fuzion language, handling of lambdas and variadic type parameters and value argument is becoming more powerful. All the details: fuzion-lang.dev/news/news_055

The Fuzion September news: An efficient and type-safe mechanism for variable argument lists for functions is one of the exciting things we are working on. All the details: fuzion-lang.dev/news/news_054

The Fuzion August news: Major news for the Fuzion language are support for loop correctness checking via loop invariants and faster static analysis. Here are the details: fuzion-lang.dev/news/news_053

The Fuzion July news: Last month brought some nice language improvements for destructuring, nullary functions and automatic unwrapping together with a number of enhancements in the base library, bug fixes and code cleanup in the tools. Here are the details: fuzion-lang.dev/news/news_052

The Fuzion June news are out: Progress on the foreign function interface is now demonstrated with an example calling the GTK toolkit. Support for right associative operators make infix operation like piping to the left <| more natural. Here are the details: fuzion-lang.dev/news/news_051

The Fuzion May news are out: Last month saw a large number of minor fixes in the Fuzion language, compiler and base library combined with some larger progress towards native library interfacing via value types and callbacks. Here are the details: fuzion-lang.dev/news/news_050

The Fuzion April news are out. The focus shifted towards a Fuzion language improvements, generally turning experience we gain using Fuzion into language improvements. Meanwhile, important progress is happening on the native interface. Here are the details: fuzion-lang.dev/news/news_049

The Fuzion repository reached the milestone of 5000 issues / pull requests. Fuzion is still in an experimental state, but it is moving ahead quickly!

The Fuzion March news are out. Loads of minor cleanup and improvements are ongoing, while major work on improving the data flow analysis engine is on the way. Here are the details: fuzion-lang.dev/news/news_048

The February Fuzion news are out. A lot of work went into the stability of the Fuzion tools, in particular case of earlier errors and making the Fuzion intermediate representation more robuts. Here are all the details: fuzion-lang.dev/news/news_047

A first version of the slides for my FOSDEM talk on effects for error handling in Fuzion are uploaded and I got onto my train just in time. The examples can be modified and run interactively online: fuzion-lang.dev/talks/fosdem...

Just a week to go until @fosdem.bsky.social! Let me know if you are also there. I will be in the Free Java dev room on Saturday. Sunday, I will talk about effects for error handling in @fuzionlang.bsky.social in the Declarative and Minimalistic Languages devroom. fosdem.org/2025/

January Fuzion news are out. Progress on all fronts: From base lib work like easier meoization (one of many issues triggered by #AdventOfCode), fixes in the front end middle end down to native support for file io operations in all backends. The details online: fuzion-lang.dev/news/news_046

Very late with this month's Fuzion news, #AdventOfCode and the Holiday season kept us too busy. Work focus was on performance of the fz tool, in particular DFA analysis, and loads of base library work applying effect handlers. All the details: fuzion-lang.dev/news/news_045

The Christmas Day's #AdventOfCode puzzle's solution took only three lines of logic using combine, zip, ∀ and count in @fuzionlang.bsky.social. src: github.com/fridis/fuzio... I am happy to have solved all 25 puzzles in Fuzion this year. The main goal was to improve Fuzion. 1/4

Late with yesterday's #AdventOfCode in @fuzionlang.bsky.social: A mixture of o-o and fp code: A parent `Wire` with abstract inner feature `state` and children `inpt` and `gate` that implement `state`. Sneaked in monadic bind operators >>=, just for option.and_then. srcs: github.com/fridis/fuzio...

Dec 23 #AdventOfCode was a fun graph problem of finding cliques in graphs. My @fuzionlang.bsky.social defines types for vertices, edges and cliques to work with. To find the largest clique, it helped to start with smaller ones and add vertices one by one. Sources: github.com/fridis/fuzio...

After almost giving up, #AdventOfCode today was easier, but not trivial. Using memoization and arrays to speed up the code in @fuzionlang.bsky.social. The sources on github: github.com/fridis/fuzio...

Almost gave up on yesterday's #AdventOfCode: First, I did not want to believe that taking different paths on the small keypads really would make a difference, got convinced after peeking into other's solutions. Concise solution using effect-based memoziation APIs. Src: github.com/fridis/fuzio...

Dec 20 #AdventOfCode reading comprehension exercise: A feature point with many inner helper features, including infix + and - operators helped to create a clean solution in @fuzionlang.bsky.social . The sources: github.com/fridis/fuzio...

Happy about a clean @fuzionlang.bsky.social solution for today's #AdventOfCode challenge: arranging towels to match designs. Caches did the trick. A nice gimmick: Added a new feature `suffix` to be called on `String`, just to make the code a little cleaner. The source: github.com/fridis/fuzio...

Dec 18 #AdventOfCode started with a path search in a maze. In part 2, the maze gradually becomes denser until unsolvable. In my solution in @fuzionlang.bsky.social, instead of re-solving each maze, I track walls from bottom/left and top/right until they connect. src: github.com/fridis/fuzio...

Had fun with today's #AdventOfCode in @fuzionlang.bsky.social: Part1 An interpreter for machine code, managed to use only pure functions. Part2 is hacky, basically guessing input 3 bits at a time. Almost tried to change the dir of time in the part 1 interperter. src github.com/fridis/fuzio...

Today's #AdventOfCode was a fairly standard shortest path finding in a 2D grid, but it turned out to actually be 3D since turning has a hefty extra cost. Here my solution in @fuzionlang.bsky.social on github: github.com/fridis/fuzio...

Today's #AdventOfCode in @fuzionlang.bsky.social requires memoization / caching of results. Since caching a value performs a state change, we need a mutate effect. We use a local mutate `M` in our `blink` function that itself remains pure. The sources on github: github.com/fridis/fuzio...

Today's #AdventOfCode solution in @fuzionlang.bsky.social is compact and fully functional. Part2 is simpler than part 1. The solution starts backwards: From the highest points creating an array of distances in a recursive function down to the starts. The source on github: github.com/fridis/fuzio...

Today's #AdventOfCode in @fuzionlang.bsky.social using mutable arrays created using a local mutate effect. Some type casts since Fuzion is not yet consistent in the index variable type for arrays (i64 vs. i32). The sources on github: github.com/fridis/fuzio...

User defined operators and type parameters in @fuzionlang.bsky.social enable a nice #AdventOfCode solution today: Adding an infix ++ op too all integer types made part 2 a one line change. Small optimization: t >= v to stop once v is too big. Sources: github.com/fridis/fuzio...

#AdvenOfCode today requires mutable two-dimensional arrays, so I enclosed the @fuzionlang.bsky.social code with a local mutate instance. The ||> operator came in handy today to destructure tuples. The sources on github: github.com/fridis/fuzio...

Today's #AdventOfCode in @fuzionlang.bsky.social defines a relation operator <? that is then used to check the conditions and to sort the pages. Tricky: Using ∀ in is_ordered to check condition on an option and get true if the option is nil. The sources on github: github.com/fridis/fuzio...
