    @snaums Yeah, I also thought this should work well with tools that do a "reverse lookup" from your binary to a software package!

    You mean it won't be fun because you can't easily modify the source code and then use it immediately? That's probably right…

    @blinry If you limit it to python, it could be fun. C/C++ code has to be compiled and that can take _a while_. Maybe it would work better on something like Gentoo. Or maybe you'd have a system, where in a special environment, everything is built from package-source once, then can be edited and recompiled in seconds.

      @agowa338 @blinry Wasn't C# simply a MS repackage of MS J++, the MS version of Java, because they were sued by Sun?
      Years ago I used to peer inside Java "jars" on XP and Ubuntu.

      I found C# far better than VB.net, but both inferior to VB6 for quick GUIs on SQL or simulating keypad and LCD of a microcontroller and prototyping the code.
      Then I went back to RF design and mostly abandoned programming apart from JAL on PIC18.
      But view source is very niche. You only want the overhead on a Dev's PC.

      @raymaccarthy @blinry

      don't know. Was before my times.

      And btw, there is basically 0 overhead from "view source" in C#, as the JIT will at runtime optimise the code and cache the compiled code until it is invalidated by you changing the source or something. In fact if you're writing powershell and the interpreter hits a loop the first few passes will be interpreted while it is in the background compiling it. And once it is done it'll on-the-fly switch over to the optimised compiled code.

          Yeah, I've often wondered about that myself. I understand that you can install the Sugar DE on Linux, generally, and get that "view source" button. But it seems specifically designed to oppose multitasking, too.

          @TerryHancock @blinry The idea of Sugar (apps full screen one at a time) in a sense is like Android. Suited to small screen which OLPC had. It's only good for certain kinds of workflow or browsing. I upgraded from 1 x QHD to 1 x 4K and then 2 x 4K and use the screens like a large desk. I need reference materials.
          I used virtual desktops on 1600 x 1200 XP over 20 years ago. I hate full screen applications except watching video / movies.
          I have a portable 17" QHD screen extending 11" laptop.

                Remember the "One Laptop Per Child" project, that developed a low-cost computer for children in developing countries? I was always amazed by a certain feature: The "View Source" button.

                When you pressed it, the source code for the currently running application would open. This was supposed to encourage tinkering with the software on your device! ❤

                I've been pondering what it would take to build that button on modern machines. Has anyone seen something like that?

                (Prototype in next toot.)

                  Oh and if you've done anything with REST-APIs or transforming file formats (aka mapping objects and such) then PowerShell is definitely killing it.

                  That's where it shines and even outperforms python in my eyes. Everything else it is kinda on-pair with python. Except you actually get working explicit typing (should you want to explicitly type something)

                  + interop with unmanaged code is easier.

                      But I agree that this can get really hairy, depending on the application.

                          Well not just that. The community also for long asked for it and the development team also eyed with breaking out of the corporate Microsoft release cycle if I recall correctly.

                            Yes, J++ was. The C# (2004?) was very much a repackage of J++, but I tried both and stuck with VB6. I had used C++ from 1987.
                            Later I did some cross platform Java designed to maintain look & feel of what ever theme of XP or Vista used, whichever desktop + theme on Linux and for Mac, though I didn't personally test the Mac. Baffles me how badly Mozilla does; should know better. The Java app talked to a device driver for a PCMCIA based 4G card (not LTE or Wimax).

                              Except I couldn't get Silverlight to run on any browser on Linux. The company I was advising did most of their work online using Silverlight.

                                Because Silverlight was shit, even when compared with Flash and Java browser plugins. But all three got replaced by HTML5 (and when apple denied them on iOS)

                                  For myself, ideally, the script would set up a #Nix flake with all dependencies in it, and activate it using direnv. Which would probably mean transforming the nixpkgs package into a flake?

                                  The script could also give you some aliases to run the nixpkgs phases like configure, patch, or build, from your current shell – I like using the fish shell, but the stdenv assumes bash. I haven't found a reasonable way to invoke the phases "in a subshell"… Getting errors like this: https://github.com/NixOS/nix/issues/15282

                                  @blinry in the Old Days, one could attach a debugger to any running process, and step through it … if the debug symbols were where the debugger could find them, you would step though the source, if not, the machine code … I gather GDB and LLDB can do similar today, tho maybe only in text mode; I’d think a distro could package everything with debug symbols and make some of that much more accessible, even adding a version-specific repo link to the debug info

                                    Is it possible to find out what shared library is responsible for some windows? I often wonder which project is actually behind the file browser or print dialog that I'm using and whether I can change it. My understanding is that these are usually delegated to an SO?

                                    @TerryHancock @blinry that sounds like information a window manager (widget manager?) would have, tho I have no idea how discoverable it is

                                      @HeptaSean Yeah, that doesn't really seem possible to figure out. For non-web applications, maybe the button could show you the tree of processes that are involved in your "current application", and allow you to pick?

                                      For expert users, I guess they could provide the name of the desired component directly.

                                      @blinry @HeptaSean for web applications, I wonder if there’s something equivalent to the debug symbols for WASM

                                        Or have the entire system built around being interpreted like Python or C#. Maybe C# would even be a better option as it's JIT compiler is better in my eyes. And it integrates better with that XML based GUI definition language Microsoft had.

                                        Edit: WPF XAML was it.

                                        @agowa338 @blinry I used to have the dream of a runtime that worked like a dynamic language interpreter, but rather than being specific to one language each call could invoke a different interpreter for whichever language was needed for the method being called. My original goal was to not have to recreate every library in every language, but the more I thought about it the more other potential benefits I saw. Even wrote my undergraduate thesis about how it might be done

                                          @blinry @korenchkin some other unsolicited advise: if the directory already exists and you decide not to delete it, change to it.
