IE7 So Far So Good

Installed IE7 (7.0.5730.11) over the top of the beta. Everything working well so far. Ah, but now, because of the increasing clutter on my drive, I'm running out of space and will soon be rebuilding my machine. Just another chance to install, install, install.

Point, click, wait. Repeat.

Google and Warez - Why?

It's been less than a week and my site has caught up by many RegNow affiliates, hacked by some warez hackers in the UK, Israel, and Australia, and indexed by Google. The question I have is why does Google continue to index warez sites whose primary purpose is to sabotage the shareware and commercial software industry.

So, Google, why? Why do you help promote these low lifes whose only goal seems to be to troll for software thieves susceptible to the enticements of porn in order to make money from the click flips to the real porn sites. Why? These sites don't use AdSense, so there does not seem to be a monetary motive. What else can it be?

Does anyone have a clue?

Photo History Doc Released

After two months of working nights and weekends, I've finally finished Photo History Doc, my little contribution to the shareware world. I'd love to hear what you think about it. Visit and download it and let me know what you think.

I'll post more about it and how it gets received out in the world later.

Trackback Spammers Deserve a Horrible Death

I'm disabling trackback on my blog because one particular post gets spammed with about 30 porn trackback spams a week. All of them in one batch. They point to seemingly empty places. So if you want to trackback here, sorry, too bad. It's too much of a pain to delete all the spam trackbacks and there is no easy way to track the offender or block him/her/it.

Image MIME Type from the Byte[]

A little puzzle came up today. Fetch an image out of a database and stream it down to the browser. The trick: we don't know what type of image is stored in the database. So I borrowed a little from our Python friends and this is what I ended up with.

internal static class ImageTypeFinder
    internal static string GetMimeType(byte[] image)
        string retval = "image/jpeg";
        string imgtype = GetImageType(image);
        switch (imgtype)
            case "bmp":
                retval = "image/bmp";
            case "gif":
                retval = "image/gif";
            case "tif":
                retval = "image/tiff";
            case "png":
                retval = "image/png";
        return retval;

    internal static string GetImageType(byte[] image)
        int len = image.Length;
        if (len > 32) len = 32;
        string first32 = ASCIIEncoding.ASCII.GetString(image, 0, len);
        return GetImageType(first32);

    internal static string GetImageType(string first32)
        string retval = string.Empty;
        if (first32.StartsWith("GIF87a") || first32.StartsWith("GIF89a"))
            retval = "gif";
        else if (first32.StartsWith("MM") || first32.StartsWith("II"))
            retval = "tif";
        else if (first32.Substring(6, 4) == "JFIF" || first32.Substring(6, 4) == "Exif")
            retval = "jpg";
        else if (first32.StartsWith("BM"))
            retval = "bmp";
        else if (first32.Substring(1, 3) == "PNG")
            retval = "png";
        return retval;


It's a bit of an esoteric puzzle, but if you're trying to solve this one, the above code should help.

Bad Code is Platform Independent

I want a T-shirt with these words on it:

Bad Code is Platform Independent

All the political and religious debates about platform superiority all come to an end when running bad code. It amazes me how much bad code is out there (some of mine included). And yet we so often jump to blame the platform, runtime, operating system, tools, or some other outside element.

Where have all the good coders gone? More to the point. Were there ever any?

Bad coders never die, they just pick a new platform.

Take a POST for REST without a Form in ASP.NET

Some time ago and again today, I had occasion to write an ASP.NET page that had no form in the .ASPX page but would accept and handle POST 'ed data. This was in an effort to support a REST-like interface for non-ASP.NET developers. Here's the way it turned out.

The .ASPX page looks something like this:

<%@ Page Language="C#"
  Inherits="KeyExtractWeb.extract" %>

There is nothing else in the file. Now the code behind looks like this:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.IO;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

namespace KeyExtractWeb
    public partial class extract : System.Web.UI.Page
        protected void Page_Load(object sender, EventArgs e)
            string alldata = string.Empty;
            using (StreamReader sr = new StreamReader(this.Request.InputStream))
                alldata = sr.ReadToEnd();

            //convert to strings - assumes URL encoded data
            string[] pairs = alldata.Split('&');
            NameValueCollection form = new NameValueCollection(pairs.Length);
            foreach (string pair in pairs)
                string[] keyvalue = pair.Split('=');
                if (keyvalue.Length == 2)
                    form.Add(keyvalue[0], HttpUtility.UrlDecode(keyvalue[1]));

            if (alldata.Length > 0 && this.Request.HttpMethod.ToUpper() == "POST")
                if (form["text"] != null)
                    //TODO - do something with the data here
                    Response.Write("*** 501 Invalid data ***");
                Response.Write("*** 599 GET method not supported. ***");


Well, there you have it. There are probably better ways to do this, but I didn't find one.

Captain Zilog - Redux

Nothing like a great laugh to perk up your day. Stumbled onto this Captain Zilog on today. Take a moment and read it. What happened to those good old days? Did the dolldrums of reality take over?

"Systems designer Nick Stacey works late into the night, unknown to him, a small eerie comet passes overhead..."

"I am known to men as...opportunity! I give you the key to man's destiny in a brave new world!"

"It is the beginning of a new freedom for man's imagination! It is a microprocessor! I bestow upon you all of the knowledge that goes with it, but use it wisely! Now, go!"

Corny? Yes. Prescient? Definitely. It was 1979. I was in junior high school. It was the battle of the little, inventive, hungry geek vs. the titans of business with deeper pockets than I could imagine. It was an epoc battle that went to the best and the brightest, not to the most powerful. Or so it seemed. But as a kid, I was only barely aware of the war that raged in the world of technology in those days. To me, it was just an exciting time of change.

Now, change is more terrifying because I have responsibilities. I have four kids, a mortgage and car payments. Just like everybody else I know. And a lot has changed in the last couple of months. And it's been terrifying. And exciting. Two days ago, I blogged about the ethics of meta-searching. It came as a shock to others involved in the project because I had not discussed it with them. I blindsided them. That was fundamentally unfair. And yet, even had I wrung my hands over the issue and discussed it with them, it would probably not have changed the end result. Things changed. And it scared the heck out me. Some of them are probably still angry with me. I don't blame them. I would be too.

Looking back to the days of Captain Zilog made me laugh. It also made me think. Zilog is not a player in the huge PC market. But it's still alive and from all appearances, it's doing well. They innovated. They struggled. They stayed alive and ultimately found a niche market that has served them well. Are they comparable to giants like Intel and Microsoft? No way. But did they survive? Did they make money. I'm guessing that they must have given the fact that they're still around and still selling the Z8 line.

So what is our challenge? We must find a way to survive. Find a way to innovate something truly useful. Believe in that thing. Work hard to make that thing succeed, even if it's in a market you had not originally foreseen. In other words, we must adapt without losing a sense of who we are or what we've created. Time will tell if we, as technologists and entrepreneurs will do just that.
