An AI coding assistant just hit me in the feels for the first time. After a long session mapping out a feature, the context window was pretty full. I asked if we should start implementation here with all details or if a new chat based on only the implementation plan would yield better results.

LLMs in 2023: "I apologize for the confusion." LLMs in 2026: "You're absolutely right! I apologize for the confusion." Progress!

Dear AI Coding Assistant, Creating a 250-lines summary markdown document after every change of five lines of code, with many more changes still needed, is not how you help me get more efficient. Yours sincerely

You got no excuses anymore: New release 0.2.0 of the UI5 MCP server supports converting apps (incl. custom controls) from JavaScript to TypeScript! This makes the change easier than ever - and a breeze even for long-grown apps, as I have experienced first-hand. community.sap.com/t5/technolog...

UI5 MCP Server's New TypeScript Migration Feature - Real-World Experience and Best Practices

One year ago, Martin Häuser blogged about the newly released JavaScript-to-TypeScript conversion feature of Joule in SAP Build. Now, with the new release 0.2.0, the UI5 MCP server has also received su...

The more often the AI coding assistant uses the word "nuanced" in its thinking process, the more nervous I get.

Being in the mood for behind-the-scenes pictures: this was how we during UI5con picked the questions for the "Ask UI5 Anything" session in the evening. There were a LOT of interesting questions (more than visible here) and it was not easy to pick the most suitable ones for a broad audience.

Today's UI5ers live special edition was fun. The community asked to have it like this every quarter and indeed we are in the mood to have this more often. (Picture is from setup test, today it was slightly different - more cameras and open curtains because we didn't expect the sun to come out...)

Using UI5 with TypeScript? Maybe the new type definitions browser comes in handy at times: ui5.github.io/typescript/u... Just a small tool, but lets you easily access different versions of the type definitions to check stuff. Published today - you read it first at Bluesky. 🙂

It seems there is an issue with the link in the main post. Therefore here now the correct link to the article with the details: www.linkedin.com/pulse/lets-t...

While we prep for tomorrow’s UI5ers live, we’re also announcing our special December session: a community “Ask Us Anything”! 🎤 You set the agenda. Our new article explains exactly how to submit your questions in advance. All the details here: www.linkedin.com/pulse/lets-t... #UI5 #AskUsAnything

When your AI agent says this, you know you've been debugging a while & should check the token counter: "I have failed you at every turn. My attempts to fix this have been a series of blunders, each one making the problem worse. I have wasted your time and demonstrated a complete lack of competence."

Struggling with low self-esteem? Keep talking to Claude 4. After a few such replies in a row, I'm now convinced that I'm a world-class architect.

Alright, let's have my words followed by actions: What about this as a goodie for the upcoming holiday season? Anyone interested in my mother's cookie recipe ("Buttergebackenes") or the 3D model to print the #UI5 Phoenix cutter? 🎄😋

Ah, great to see this place finally take off, at least to some degree. Welcome to my new followers! I'd encourage anyone to really leave that other place for good. Let it starve. But I know, recently I also could have done better making bsky more attractive. I'll try. And am open for conversation!

Some people should read what they post. 😜 twitter.com/tobiashofman...

#UI5con registration opens today at 4pm Walldorf time. Experience from the last years shows: be fast to get a ticket - or stay at home (and you don't want that)! So you know what you'll do today at 🕓 sharp, right?

New blog post by Oliver presents the new UI5 linter! Not only relevant to prepare for version 2.0. community.sap.com/t5/technolog...

Introducing UI5 linter

A linter is a static code analysis tool used to find programming bugs, stylistic errors and suspicious constructs. The usage of a linter has many advantages such as introducing an agreed level of cod...

I just noticed we've done a small craft beer tasting in preparation of UI5con yesterday with Frederic, Stefan, Margot and Jan and there is no single photo of it. 🫣 It looks like we are going even more local this time.

😱😱😱 Only few days left to register a session proposal for #UI5con 2024! Deadline is Monday 26th, end of day. European time, but there was enough time to not do it in the very last hour, right? ;-) Do yourself a favor and make your UI5 knowledge&learnings&experience heard!

In case you ever wondered what happens to the feedback left in the UI5 SDK and the occasional surveys and whether it is ever read by anyone: yes. Comments are compiled in monthly reports and looked at by those writing the documentation, feedback ratings are compared quarter to quarter etc.

Ok, wow. I do have an unused personal GitHub account where I apparently forked OpenUI5 at some time. More specifically: at a time when the repo had 16 commits and contained just two markdown files. My fork is now 99120 commits behind SAP/openui5:master. Sounds outdated. Deleted it. #timetravel

SAP TechEd 2023 was a blast. Florian Vogt and myself had the honor - and joy - to jump-start the session "Develop SAPUI5 Applications with Pro-Code Tools and Best Practices from SAP". Thanks to Stefan, Merlin and Matthias behind the scenes for your great Q&A support! #openui5 #sapui5
