  • 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.");
    }

    “Observable universe” isn’t how much we can see, rather how much it is theoretically possible to observe by any physical means.

    I also don’t think that water drop fact is correct. The estimated number of stars in the observable universe is 10^24, which is about an order of magnitude more than 1 mol, and 1 mol of water is about 18g, which is quite a bit more than 10 drops.


  • 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.
