Well, 201 lines to be exact. How fool I was.
Short story: we have a strange TIFF file. There has to be an image somehow stored there, but double clicking on it gives nothing. By the way, this file, together with a million more of them, contains the entire document archive of a company. Some seven years ago they purchased a package to archive digitized versions of all their paper documents, and have been dutifully scanning and archiving all their documents there since then. After doing the effort of scanning all those documents, they archived the paper originals off site, but only organized them by year. Why pay any more attention to the paper archive after all? In the event of someone wanting a copy of an original document, the place to get it is the document archiving system. Only in extreme cases the paper originals are required, and in those cases yes, one may need a couple of hours to locate the paper original, as you have to visually scan a whole year of documents. But is not that of a big deal, especially thinking about the time saved by not having to classify paper.
All was good during these seven years, because they used the document viewer built into the application that works perfectly. However, now they want to upgrade the application, and for the first time in seven years have tried to open one of these files (that have the .tif extension) with a standard file viewer. The result is that they cannot open the documents with a standard file viewer, yet the old application displays them fine. Trying many standard file viewers at best displays garbage, at worst crashes the viewer. The file size is 700K in size, the app displays them perfectly, so what exactly is there?
Some hours of puzzling, a few hexdumps and a few wild guesses later, the truth emerges: the application is storing files with the .tif extension, but was using its own "version" of the .tif standard format. Their "version" uses perhaps the first ten pages of the .tif standard and then goes on its own way. The reasons for doing this could be many, however I always try to keep in my mind that wise statement: "never attribute to malice what can be adequately explained by incompetence"
The misdeed was, however, easy to fix. A quite simple 200 line C program (including comments) was able to extract the image and convert it to a standard file format. At least on my Linux workstation.
I was very happy with the prospect of telling the good news to the business stakeholders: your data is there, you've not lost seven years of electronic document archives, it is actually quite easy and quick to convert these to a standard format and you can forget about proprietary formats after doing that. However, I then realized that they used Windows, so I had to compile the 200 line C program in Windows just to make sure everything was right.
Checking the source, I could not spot any Linux specific things in the program, all appeared to be fairly vanilla POSIX. However what if they are not able to compile it, or the program does something differently? This is one of the moments when you actually want to try it, if only to be absolutely sure that your customer is not going to experience another frustration after their bitter experience with their "document imaging" system and to also learn how portable your C-fu is across OSs. Too many years of Java and PL/SQL and you get used to think that every line of code you write has to run unchanged anywhere else.
So I set myself to compile the C source in Windows before delivering it. That's where, as most always, the frustration began. The most popular computing platform became what is now, among other things, by being developer friendly. Now it seems that it is on its way to become almost developer hostile.
First, start with your vanilla Windows OS installation that likely came with your hardware. Then remove all the nagware, crappleware, adware and the rest of things included by your friendly hardware vendor in order to increase their unit margins. Then deal with Windows registration, licensing or both. Then patch it. Then patch it again, just in case some new patches have been released between the time you started the patching and now that the patching round has finished. About four hours and a few reboots later, you likely have an up to date and stable Windows instance, ready to install your C compiler.
Still with me? In fairness, if you already have a Windows machine all of the above is already done, so let's not make much ado about that. Now we're on the interesting part, downloading and installing your C compiler. Of course, for a 200 line program you don't need a full fledged IDE. You don't need a profiler, or debugger. You need something simple, so simple that you think one of the "Express" editions of the much renowned Microsoft development tools will do. So off we go to the MS site in order to download one of these "Express" products.
So you get here and look at your options. Now, be careful, because there are two versions of VS Express 2012. There's VS Express 2012 for Windows 8 and there's VS Express 2012 for Windows Desktop, depending if you're targeting the Windows store or want to create... what, an executable?. But, I thought Windows was Windows. In fact, I can run a ten year old binary on Windows and will still work. Oh, yes, that's true, but now MSFT seems to think that creating Windows 8 applications is so different than creating Windows Desktop applications that they have created a different Express product for each. Except for paying VS customers, who have the ability to create both kinds of applications with the same product. Express is Express and is different. And you don't complain too much, after all this is free stuff, right?
As I wanted to create a command line application, without little interest in Windows Store, and without being sure of whether an inner circle of hell awaited if I choose one or the other, I simply choose VS Express 2010. That will surely protect me from the danger of accidentally creating a Windows Store application, or discovering that command line apps for example were no longer considered "Windows Desktop Applications" You may think that I was being too cautious or risk averse at this point, but really, after investing so much time in compiling a 200 line C command line utility in Windows I was not willing to lose much more time with this.
Ah, hold on, the joy did not end there. I finally downloaded VS 2010 Express and started the installation, which dutifully started and informed me that it was about to install Net 4.0. How good that the .Net 4.0 install required a reboot, as I was starting to really miss a reboot once in a while since all the other reboots I had to do due to the patching. At least the install program was nice enough to resume installation by itself after the reboot. Anyway, 150 MB of downloads later, I had my "Express" product ready to use.
What is a real shame is that the "Express" product seems to be, once installed, actually quite good. I say "seems" because I did not play with it much. My code was 100% portable in fact, and it was a short job to discover how to create a project and compile it. Admittedly I'm going to ship the executable to the customer the build with debug symbols, as I was not able to find where to turn off debug information. Since the program is 30K in size, that's hardly going to be a problem, and if it is, it's 100% my fault. To be honest, I lost interest in VS Express 2010 quickly once I was able to test the executable and verify that it did exactly the same as the Linux version.
But the point is, in comparison, I can build a quite complete Linux development environment in less than two hours, operating system installation included, incurring in zero licensing cost and using hardware much cheaper than the one needed to run Windows. Why is that to create a Windows program I need to spend so much time?
What happened to the "developers, developers, developers" mantra? Where is it today? Anyone old enough can remember the times when Microsoft gave away free stacks of floppy disks to anyone remotely interested in their Win32 SDK. And those were the days without internet and when CD-ROMs were a luxury commodity. And the days when IBM was charging $700 for their OS/2 developer kit. Guess who won the OS wars?
Things have changed, for worse. Seriously, Microsoft needs to rethink this model if at least they want to slow their decline. At least, I guess I've discovered one pattern that probably can be applied to any future OS or platform. Today, to write iOS/MacOS programs you need to buy a Mac and pay Apple $100. The day it becomes more difficult, complex, or expensive (as if Apple hardware were cheap), that day will be the beginning of the end for Apple.
