<p> In short, after a Linux kernel update (6.5.8-200.fc.x86_64 on Fedora KDE), I can't use the top button of my pen on my tablet. This is really affecting my digital painting workflow! </p>

schestowitz

<p> Right-clicking on the pen is an essential part of my workflow. Right-click on a layer in Krita to get the menu, right-click while using the Transform tool to get the transformation options, right-click on the canvas to get the pop-up palette! ...And I'm not even talking about how difficult it is to handle files and the D.E. without right-clicking. </p>

<p>This tiny computer is the Mars CM. It's the exact same size and shape as the Raspberry Pi Compute Module 4. It should be a drop-in replacement. And on its box it says it supports 4K, Bluetooth and WiFi, and has gigabit Ethernet. It's also supposed to have PCI Express! </p>

<p> In the previous part of this series, I got the Acorn Atom working. But I don’t just want it working, I want it in a good, usable condition. So, there is a little more work to do. Here is where I am at.</p>

<p> The other day I had to dive into the ksmserver code, the core of session management in KDE Plasma, but found it all a bit difficult to read. If only I could get a callgraph I thought… </p>

schestowitz

<p> Turns out it actually is possible! </p>

schestowitz

<p> In fact it is almost too easy with clang/llvm. There are already solutions that attach LLVM bitcode to existing binaries. e.g. gllvm. gllvm basically is a shim sitting between ninja and the actual compiler and injects some behavior for us. This enables the use without having to refit anything in our existing code. You might note that clazy, our most excellent code analyzer, works in a similar

fashion. </p>

"As to the second question, the term 'objective technical problem' is not in itself a hard rule and the EPO in fact applies a balanced approach. The problem must be objectively solved by the claimed subject matter compared to the closest prior art/starting point document (T20/81). On the other hand, a purely objective approach does not work well in the field of chemistry, where patent monopoly applications with only compound claims and

only disclosing new compounds and their preparation, without indicating any use, do not serve the technology dissemination purpose of patent monopoly publications well (I understand this was an episode from the German national case law). G2/21 confirms that the EPO applies a balanced approach by requiring that the application as filed provides sufficient support for the technical effect in the application as filed (my analysis is that G

2/21 leaves the height of the threshold open to the Technical Boards of Appeal to decide in each case but for saying the threshold can not be zero).<'
