    i is still a value type, that never changes. Which highlights another issue I have with the explanation as provided. Using the word “reference” in a confusing way. Anonymous methods capture their enclosing scope, so i simply remains in-scope for all calls to those functions, and all those functions share the same enclosing scope. It never changes from being a value type.








  • C# .NET using reflection, integer underflow, and a touch of LINQ. Should work for all integer types. (edit: also works with char values)

    // this increments i
    private static T Increment<T>(T i)
    {
        var valType = typeof(T);
        var maxField = valType.GetField("MaxValue");
        var minField = valType.GetField("MinValue");
        if (maxField != null)
        {
            T maxValue = (T)maxField.GetValue(i);
            T minValue = (T)minField.GetValue(i);
    
            var methods = valType.GetTypeInfo().DeclaredMethods;
            var subMethod = methods.Where(m => m.Name.EndsWith("op_Subtraction")).First();
                   
            T interim = (T)subMethod.Invoke(
                null,
                [i, maxValue]);
    
            return (T)subMethod.Invoke(
                null, 
                [interim, minValue]);
        }
        throw new ArgumentException("Not incrementable.");
    }
    


  • I’m the primary developer for a third party tool for Elite Dangerous and this is basically my entire thought process when I want to work on it.

    I could work on Observatory…

    Or I could play some Elite…

    Or I could just stare at my screen ineffectually for several hours.

    Staring at the screen wins frighteningly often.



  • Half Life Alyx, Lone Echo, and Asgard’s Wrath are all incredible experiences that actually feel like “real games” that made meaningful and justifiable use of VR.

    Beat Saber and Robo Recall get honorable mentions from me as well because while neither is groundbreaking, both execute their particular niche more or less perfectly.

    Browsing various VR software storefronts now you find basically nothing like any of the above. Everything seems to be trying to mimic the mobile game “quick distraction” approach and shovel out as much garbage as possible rather than creating anything engaging. For anyone who believes that VR has genuine potential for exciting new experiences, as I do, it’s incredibly disheartening.







  • In Force of Nature (S07E09) they discover that high speed warp travel can damage the fabric of space and a speed limit of warp 5 is set by the Federation for non-emergency travel. It gets referenced a couple of times in the final season of TNG but doesn’t come up much after.

    Though arguably Voyager’s situation and the Dominion War could both be reasonably considered “emergencies”. It’s also been suggested that the Federation was very quick to develop warp drives that didn’t cause this damage (this is one official but never-published explanation given for the Intrepid Class variable geometry warp nacelles).
