   You're right, gdb has had some reverse debugging support since version 7.0 released in 2009. https://www.gnu.org/software/gdb/news/reversible.html

   Are you trying to dispute that compilers are large and complex? It seems like you are saying that if the language is simple, a non-optimizing compiler for it can be simple, which seems somewhat obvious. I think the "microcosm of comput

   Is it possible the NN is just memorizing each course? I don't think he mentioned in the video what the train/test split was.

   Xamarin.Mac is the project emcompassing bindings from Cocoa (i.e. native macOS) to Mono/.NET, the interface with Xcode for building Cocoa UIs, and Visual Studio for Mac (previously called Xamarin Studio). Essentially, Xamarin.Mac allow

   I've had good luck so far with Xamarin.Mac + traditional WPF for macOS and Windows respectively, with a PCL containing 90% of the shared code. Xamarin.Mac doesn't seem neglected to me, and the forums are decently active for suppor

   For your example, a regular expression with named capture groups would be all you'd need, e.g.: https://pythex.org/?regex=%5E(%3FP%3Cuser%3E.%2B%3F)%20(like... If you start to need more complex features in your grammar

    I think implementing a simple text editor with undo/redo support is a worthwhile exercise for everyone to do at least once in their career. It's a great example of something that on first glance seems simple, but has quite a bit o

    Pixel-perfect is hard to do in SVG (at least in my experience). You have to be careful to align path geometry to half-pixel values so that whole-number stroke widths end up falling on a pixel boundary. And once you start scaling the SVG to

    Currently, there's no mechanism to do that. However, I'm intrigued -- can you explain more about the use case you're thinking of?

    Not confidential -- Vexlio's written in C#, and uses Xamarin.Mac for the bindings to the Mac world. PDF and PNG are both generated by the Skia library (skia.org).

    A while ago I wrote a tiny language (called bish) that was an attempt at finding a middle ground for this problem. Essentially, you write your shell scripts in bish, with sane syntax and semantics (example: function return values, which are

    I used the ShareX screen recorder ( https://getsharex.com/ ) to record each GIF at 30 fps. I believe underneath ShareX is using ffmpeg to do the encoding. They were a bit of a pain to make, as it's a very manual process

    You can already export to SVG, which is a widely enough supported graphics format that there are quite a few standalone tools to perform various transformations on it. In fact, the .vex file format is a just very thin wrapper around SVG con

    I won't rule it out, as it would probably be a (relatively) small extra bit of work to load a C# assembly which interacts with the same API exposed via NLua, but Lua plugins will come first.

    The legalese states that you are allowed to install and use Vexlio on up to 3 machines per license key.
