How to select the best words to guess in Wordle?

Here's my strategy:

1.  Find the frequency of letters in words for five letter words:

AESORILTNUDCYMPHBGKFWVQJXQ

2. Now going left to right find words that contain the most frequently used letters.

AESOR ILTNU DCYMPHBGKFWVQJXQ

How to find what words contain AESOR?

We can use the tool "grep" on unix with something like this which finds all five letters words with AESOR.

[Trigger warning: actual unix tools code😱:]

grep "^[a-z]\{5\}$" /usr/share/dict/words | grep a | grep e | grep s | grep o | grep r

One word pops out: “AROSE”.

2. Now look at the letters that are next:

ILTNU DCYMPHBGKFWVQJXQ

Fortunately one word fits the bill, "UNTIL"

3. Looking at the next letters, we don't have a word that contains "DCYMP", so we get as many as we can and then get the next most frequently used letters:

DCYMPHBGKFWVQJXQ

Which produces "DUCHY".

Then the next word is "GAWKY".

Enjoy.

So when you get a "w", it's usually in the first two letters, and a "y" is near the end.

How to Programmatically Add Tags to Files in OS X on a Mac Using C# Without Libraries

While working on photos, I wanted to programmatically add tags to photos. The tags would be read from a file. I formally used Finder to do this, but it can be tedious for a large universe of tags and there's no record of the association. Here's my solution which is really awkward and brittle. Surely there is a better way. Please add your comments on that way. Until then, I'll use this code.

using System;
using System.Diagnostics;

namespace ImageDescriptions
{
    public class Utilities
    {
        public static string? executeShellCommand(string scriptFile, string arguments)
        {
            var processInfo = new ProcessStartInfo()
            {
                FileName = scriptFile,
                Arguments = arguments,
                UseShellExecute = false,
                RedirectStandardOutput = true,
                CreateNoWindow = true
            };
            string? result = string.Empty;
            Process process = Process.Start(processInfo);   // Start that process.
            while (!process.StandardOutput.EndOfStream)
            {
                result = process.StandardOutput.ReadLine();
                System.Console.WriteLine("result: " + result);
            }
            process.WaitForExit();
            return result;
        }
        /// 

        /// Sets tags on a file in OS X.
        /// This is really awkward and brittle.
        /// 
        /// Comma separated list, e.g., "red,black,green"
        /// file to which we add tags
        public static void SetTags(string? tagCsv, string filename)
        {
            System.Console.WriteLine($"SetTags: '{tagCsv}', '{filename}'");
            var tagXmlString = string.Empty;
            if (tagCsv == null || String.IsNullOrWhiteSpace(tagCsv)) { return; }
            var tags = tagCsv.Split(',');
            foreach (var tag in tags)
            {
                tagXmlString += "" + tag.Trim() + "";
            }
            var scriptFile = "/usr/bin/xattr";
            var arguments = " -w"
               + " com.apple.metadata:_kMDItemUserTags"
               + @" """
               + @" "
               + tagXmlString
               + @" """
               + " " + filename;
            System.Console.WriteLine($"executeShellCommand: {scriptFile}, {arguments}");

            Utilities.executeShellCommand(scriptFile, arguments);
        }
    }
}

Here's a program that reads a data file and then calls "SetTags()":

using ImageDescriptions;

public class ImageDescription
{
    public static void Main(string[] args)
    {
        if(args.Length < 1)
        {
            Console.WriteLine("usage: ImageDescription ");
            Environment.Exit(1);
        }
        string filename = args[0];
        FileStream file = File.OpenRead(filename);

        var lines = File.ReadLines(filename);
        foreach (var line in lines)
        {
            Description description = new Description(line);
            Console.WriteLine(line);
            Console.WriteLine(description);
            Utilities.SetTags(description.tags, description.name);
        }
    }
}

A line from the data file looks like this:
