New Style Signal/Slot Connection
Yes, I know. The last post on the assistants is rather boring. And yet these days I have been working on the snapshot docker, though it still seems a little (just a little, you see) unfinished as Dmitry is said to experience a relatively high delay when switching between snapshots. However this is not what I can reproduce on my older laptop, so I am really waiting for his test results in order to further investigate the problem.
But there is something interesting happening just when I am randomly testing things. From Krita’s debug output, I saw QObject::connect() complaining about the arguments I passed, saying it is expecting parenthesis. “Okay,” I thought, “then there have to be something wrong with the code I wrote.” And that was quite confusing. I remember having used member function pointers in those places, got a compile-time error since KisSignalAutoConnectionsStore did not support the new syntax, then switched back to the SINGAL() and SLOT() macros. KisSignalAutoConnectionsStore is a helper class to quickly (dis)connect a group of connections. One can use the addConnection() method to add a connection, and use clear() to remove all connections made before.
Well, everything good, apart from the fact that I missed the parenthesis, which I did not discover until I looked into the debug output. So I asked Dmitry why not add the new syntax to KisSignalAutoConnectionsStore, and he said we should.

Learn PyQt: Gradient
This custom PyQt5/PySide2-compatible widget provides a gradient designer providing a handy interface to design linear gradients in your applications. A new gradient can be created simply by creating an instance of the object.
gradient = Gradient()
The default gradient is black to white. The stop points are marked by a red box with a white line drawn vertically through it so they are visible on any gradient. -

5 transferable higher-education skills
As a developer jumping head-first into technology after years of walking students through the process of navigating higher education, imposter syndrome has been a constant fear since moving into technology. However, I have been able to take heart in knowing my experience as an educator and an administrator has not gone in vain. If you are like me, be encouraged in knowing that these transferable skills, some of which fall into the soft-skills and other categories, will continue to benefit you as a developer and a professional.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
