The greatest software design blunders of all time

Security that's built on 32bit bitmasks? In 2009?
Unfair. Pretty much all modern Unix variants have some form of ACL.

then creating/depending on a "systems" language that has no concept of a string as a basic data type and instead relies on a null termination character for a string's ending? WTF??
How is Windows (or any other modern OS) different in this regard? Besides, what is an alternative? Do you seriously suggest a GC-dependent string class for kernel development?

Yeah but that's been a very recent development, something that's only become widespread in the last couple of years. ACLs have been around forever. And *still* dealing with the bitmasks are the primary way of dealing with file permissioning. OpenVMS had them in the early 80's, and NT had them from the outset in early 90's.

No, the simple solution is a string class/data type that has it's length encoded with it. Searching for null terms, and dealing with (or failing to deal with) mal-formed strings has been one of the biggest source of errors, buffer overflows, etc for decades! Just about every major language out there has some concept of a string, and a string length in the data type, instead of doing what C does. You certainly don't need a GC for that. Windows is slightly different in that string/text data is not the primary representation for just about everything like it is in unix. Much of the data is in structs and in binary form. In the Windows kernel plain C-style strings are not used (or didn't used to be when I last looked), instead there is a string like struct that contains the string length (the same kind of thing that OpenVMS uses) as well as the string buffer. However, that said, the fact that Windows uses plain C-style strings in it's user land API's *is* stupid.

Unix. All of it.
Including Mac OS X? ;P Seriously, I like Unix. It is a very geek-friendly system. Of course, the GUI part is horrible (except Mac OS X?), but why would you even want to run a GUI desktop system on Unix?

Or OpenVMS, or DOS...

Also I might be wrong but I'm sure my old Windows 2000 had this on the logon screen as well.

You debugged a program with vi?

OK, Nemanja is not going to agree with us, but what the hell.
Well, I am not going to argue that you never want to go back there :)
VI was the "IDE". DBX for debugging. For me, the editor, debugger, the OS, and everything else (including the Unix nerd whom I worked with) all looked the same. Totally blank. :)

In an effort to make our own mistakes look more reasonable, I invite you to post the big and high-profile blunders others have made. The scope is broad; anything from user interface to file formats goes. To get us started, I'll suggest this: MS-1: No way to switch input locale when logging on to windows. This is just brilliant. If you've defined a password using a different input locale from the system default (perhaps because your keyboard isn't made for the default locale) you'll find yourself in an ackward situation after a reboot. You can't see what you're typing, it isn't what's printed on the keys you press, and you've got maximum 3 attempts to get it right... Of course, the password is sure to contain special characters, making everything harder yet! Any others?
I'd have to say MS Access. It just sucks. I'm currently working on a project to convert several Access97 databases and programs into C# and SQL Server. Been going on two years now. Just when I think I'm done, I'm not. It just won't die. X|

And all I'm saying is that it's stupid to have all locales installed on all PC all over the world just in case somebody didn't configure his PC to support his password preferences.

I suppose it's too much to ask for Americans to understand the first thing about locale-related problems
Yeah, blame Americans, seems reasonable :) But this should go in Soap Box/Back Room.

If you would be kind enough to explain to me why choosing ANY locale that the machine is ABLE to support just for login would be a "blunder" I am all ears.
I specifically referred to installing locales using log-in screen, but hey why should you bother to understand what people are saying when can rant.

Yes, implying I had said so too. I did say "add locales", so perhaps it's understandable that you missed what I meant: to the list shown to the user trying to log on. Your reply was nevertheless very much against the spirit of the thread, which was to make our own mistakes seem more reasonable. I guess you just didn't see the humour in it. As for this specific design, I don't know why my XP doesn't show the "NO" locale (though from what someone else posted it seems there's a login user and the locales associated with this user will be displayed), but I know it's installed.

It's out of the box edit grid does more than the asp.net equivalent in that access's will create a dropdown box for a foreign key lookup table via the gui vs having to manually muck around and edit the aspx itself. Discovering that blew my the time estimate for my first asp.net app out of the water; since I had assumed it would be least as capable as a 10yo POS application. :doh:

Not sure if you can really compare Access vs. ASP.NET, but yeah, Access does a lot of the nitty gritty stuff for you, allowing a bubble gum chewing secretary to look like a computer genius to the boss! :-D
