Just published a new version of punyexpr : it now support hooks to modify the way the expression is evaluated. I need it for... reasons :-D www.npmjs.com/package/puny...

What’s amazing with AI is that I have tons of ideas but not so much time. With the help of LLMs I can go beyond my time constraints and develop way more than before !

I was today's old when I learned about this Node.js error : Warning: Detected unsettled top-level await Playing with streams & async iterator on a stream that does not end is a bad idea !

Playing a bit with vibe coding and testing agents. It's funny to see how a specification you hope to be clear can be interpreted differently by the models. I end up writing ASCII wireframes to "fix" the look of the UI. I would like to apologize to PO & UX people I worked with... now I feel the pain.

Had some fun this week end… it’s been a while I didn’t play with LEGOs but my heart melted when I saw this set !

Got my first test report out of ui5-test-runner@6... Still a long way to go through but this first milestone is exciting

Now I am questioning myself about which game I should play next ? I am looking into the Suikoden I & II remasters on switch or maybe one of the Dragon Quests ones. Any opinion ?

Radiance done… 103% in 62 hours … the last 5 hours on Radiance😅

Finished the « bad » ending of hollow knight. 38 hours, 84%. What a ride !

I am still waiting for my job offer at 400K/year ;-)

Working with Node.js' WorkerThreads, I learned few useful lessons: * Only the main thread has access to process signals and native stdout * As a consequence, not all packages are designed to be executed in a WorkerThread 1/2

These days, most ui5-test-runner problems I hear of are related to the execution being stuck without any explanation... This is a real pain to detect and troubleshoot in the current version. Version 6 will address this very specific issue using a different approach !

Useless? absolutely But I had to do it... new logo for the runner themed with UI5 colors.

Forget about ts-node or tsx, Node.js 24 provides convenient ways to execute "natively" TypeScript, see nodejs.org/api/module.h...

I am looking for a code name for the next version of ui5-test-runner. My hope is to go with "FTL" but "FTK" (Faster Than Karma) will also do it ;-)

Wouhou ! I created a multithreaded logger in Node.js... The goal ? * free up bandwidth for CPU intensive tasks, * have a synchronous (hence thread blocking) compressed (hence CPU intensive) trace storage, * implement a nice console output which does not block other threads. was a fun ride !

Playing with Node.js threads (i.e. Worker)... It's a brand new world...

"You're absolutely right! " ...thank you LLM...

It’s a big responsibility when you decide to completely rewrite a component. Yet, I take this opportunity to improve all the little details that were bugging me over the last 5 years. It will take time but it should be rewarding.

More than 80 different options for the ui5-test-runner command line. Quite some work to clean the mess and make it maintainable...

I gave a presentation tonight about MetaProgramming at JS Montreal. Got good feedback. arnaudbuchholz.github.io/decks/MetaPr...

I like refactoring: this is an opportunity to rewrite with the knowledge of all the faced challenges. Yet, this feels like a huge mountain to climb.

Sometimes I feel like when I want to ask a question to the LLM, I spend so much effort to formulate it the right way that I almost get the answer by myself...

Big release for [email protected] github.com/ArnaudBuchho...

Hmm... I'd remove #Ubuntu from that chart and replace it with #LinuxMint

My cat contribution

Tried to create a simple command line app with GEMINI to validate an idea... A bit disappointed (some mistakes) but got it to work. It certainly saved me a bit of time...

Using compression (& decompression stream) I was able to reduce the HUGE html report (168 MB) down to 9 MB... and it loads fine (& fast) in the browser !

So... you can actually decompress content inside a web page. Today I learned about DecompressionStream : developer.mozilla.org/en-US/docs/W...

Got it, trying to open a 168 MB HTML report is not a good idea...

OK QUnit is old... but it is good ! Believe it or not but I am currently mapping jest APIs to QUnit... and it works !

From 6 min to 4 min with a simple trick... Sometimes optimization really feels great !

2 hours to enable my apple device on my Windows 11... I had to extract drivers from an old version of iTunes to make it work... Just why ?!?

Working on automating OpenUI5 existing tests with ui5-test-runner (since karma is no more maintained). Some metrics on sap.ui.core tests : - 600+ unit tests - 17 minutes to execute (10 parallel executions) - 29+ tests failing (need to check) - A 172 MB HTML report (!) Room for improvement !

Something big is coming soon to ui5-test-runner... I never thought I would be able to achieve a bridge between jest and QUnit. The reality is that both JavaScript and QUnit are powerful tools.

Learning about meta programming: a programming technique where programs manipulate or generate other programs as data. That’s what I am doing !

Just released version 1.2.0 of punyexpr, a minimalist (5085 bytes) and safe expression compiler and evaluator. www.npmjs.com/package/puny...

I am currently working with Abstract Syntax Tree to manipulate JavaScript code... I feel like a surgeon trying to transplant an organ : tricky but fun !

I don't know why it happens now but I like the trend !

Just updated punyexpr, it now exposes types definition and can be used in a CommonJS or ESM project. arnaudbuchholz.github.io/punyexpr/sam...

🚀 Exciting news! Version 5.7.0 is here, introducing new options for test automation using selenium-webdriver and a docker running the selenium server. This update marks the initial phase in setting up test grids with ui5-test-runner. github.com/ArnaudBuchho...

Yesterday, I had the opportunity to present my personal project psbots at JS Montreal. I showcased the engine's capabilities through an online REPL and a PONG game, where the paddles were controlled by a compact PostScript program. arnaudbuchholz.github.io/decks/psbots.html

Cool LLM visualization bbycroft.net/llm

Fixed a bug that was preventing code coverage to work when doing library testing... The runner is more and more used ! github.com/ArnaudBuchho...

Est-ce qu’il y a une communauté JS en Français ?

Every day I'm learning... www.npmjs.com/package/happ...

Big ui5-test-runner release today : 5.5.0 ! Introducing the batch mode : it is now possible to test more that one project with a single command ! github.com/ArnaudBuchho... #ui5 #testing-ui5

Just released [email protected] : a lightweight web server configurable with regular expressions. I added the possibility to build responses directly through the custom handler result. github.com/ArnaudBuchho... (REserve is a core part of ui5-test-runner)
