In light of recent events, it’s worth remembering this isn’t the first time the US and Israel have jointly targeted Iran’s nuclear program.
Earlier instead of bombs they used something less spectacular but just as dangerous: a highly sophisticated piece of malware called “Stuxnet”.

Modules ftw!
One of the coding practices I dislike the most is grouping code into folders based on the type of code they contain. You know the ones: Views, Repositories, Functions, Interfaces, DTOs, Entities, Enums, Requests... the list goes on.

How did your organizations react to the change in licensing for Docker Desktop? Did they simply pay for the license or began looking for alternatives?

Conventions aren't bad, but with great power comes great responsibility to document them. I can recall a few cases where devs were unaware of some implicit features and implemented their own similar explicit ones. Not only a waste of time, but also a big mess!
It sounds so nice: you create a class, implement an interface, or annotate it with an attribute, and magically, everything connects. There was a time in the .NET space when this was a very popular practice. However, experience has shown that it often obscures the codebase. (cont'd)

What a clever idea! Using server latency to pinpoint user locations globally. While complete accuracy isn't assured, privacy might be at risk.
Proof of location for online polls - Network Latency Geolocation
Information about a device's physical location can be inferred by measuring the time it takes for signals to travel between the device and a known server location. As the speed of light cannot be exceeded according to the known laws of physics, a maximum possible distance can be established with certainty, based on the signal latency.

As a .NET dev on a Mac, I favor JetBrains Rider over Visual Studio. I'm fortunate to use tools I enjoy, unlike some .NET folks. Finding a .NET IDE for non-Windows OSes is hard as there aren't many viable options. I'm not considering VS Code because it doesn't provide a ready-to-use IDE experience.

Google rolled out Gemini to all Google Workspace customers. It's supposedly a smart assistant.
Yet to be able to ask a question to which the answer in not:
"I can't help with that. Do you need help with anything else?"
Good example of over-promise, under-deliver.

I wonder what other LLM exploits we will see in the coming years. Many surprises await us. This makes me even more cautious about using LLMs. They give us a lot of opportunities to create interesting software features, but they also increase the surface of potential attack.
