What Hacker News says?
Cool. The part that is released already is described here [0]. You can point at some code and give brief instructions, and it will ask the model to expand them, giving several options. E.g. if you point at a vector class and just "Distance()" for prompt, it will make assumptions like "you want to add a function calculating distance from (0,0)", "function calculating distance between 2 vectors", etc. It runs pretty f…

HN discussionThere's a pretty good sweet spot in between vibe coding and manual coding. You still think out all the classes, algorithms, complexities in your head, but then instead of writing code by hand, use short prompts like "encapsulate X and Y in a nested class + create a dictionary where key is A+B". This saves a ton of repetitive manual work, while the results are pretty indistinguishable from doing all the legwork yours…

HN discussionAdding entire files into the context window and letting the AI sift through it is a very wasteful approach. It was adopted because trying to generate diffs with AI opens a whole new can of worms, but there's a very efficient approach in between: slice the files on the symbol level. So if the AI only needs the declaration of foo() and the definition of bar(), the entire file can be collapsed like this: class MyClass…

HN discussionYou need to do it in smaller, incremental steps. Outline the overall architecture in your head, ask the AI to create empty structs/classes. Build it. Ask it to implement one part, leaving others empty. Test it. Ask it to add the next thing, and so on. Every step should only affect a handful of classes or functions, that you can still keep in your head and easily verify. Basically, same thing as if you were doing it…

HN discussionThis kind of project is really nice, there is a great design document which talks about issues building logic analyzers out of Cortex-M boards here: https://sysprogs.com/w/how-we-turned-8-popular-stm32-boards-... which you may find helpful as well. Of note, the Teensy-4.1 uses the Cortex-M7 which is even more impressive than the Pico in terms of raw computer. A long time ago there was a company called "boulder creek…

HN discussionYou probably want kgdboe for this kind of thing? http://sysprogs.com/VisualKernel/kgdboe/ On a embedded targets you'd have a JTAG port for full out of band debugging, but that's obviously not an option for your typical desktop scenario.

HN discussionhttp://sysprogs.com/VisualKernel/tutorials/kgdb/ It supports many VS features. The same people also sell a debugging program that claims to support everything debugging-related of Visual Studio, but I don't know if that's integrated into this VisualKernel product, or just a subset.

HN discussionI don't think it's sarcasm. It looks like VisualKernel is a real product that this company is selling. They also make VisualGDB and a bunch of other tools: http://sysprogs.com/products/ Here's the company's "about" page: http://sysprogs.com/about/
