Maybe he's trying to be helpful... but as a perl programmer, I say, mod parent funny!!!
My philosophy (yes, everybody seems to have one these days) is this:
1. Define the rules for valid data. 2. Classify types of invalid data. 3. Break the rules down into a series of discrete steps. 4. Write the validation code, using the simplest semantics possible. 5. If data validation fails, try to match the problem to one of the invalid data classifications and throw an exception.
Yes, it sounds complex, but for the type of work I do, we need to: 1. Check our data for correctness. 2. Reject invalid data. 3. Identify what went wrong 4. Be able to quickly understand the rules by reading the code, for future maintenance.

Seriously, and of course this is assuming that it ships with development tools of some sort, Imagine the benefits for a company allowing unchecked development on their new platform... especially a platform using Cell which will find applications in other areas... gotta go... work.
Are you a programmer... or do you just play one on TV? Seriously, I need to burn some karma on this one.
I can't even quote sections of your post 'cause I'd be using the whole thing. First off, let me *defend* Windows (easy there, skript kiddeez, I'm typing this from my debian box)
The Win32 API is big and ungainly in some places. It's not always consistient, and it's implementation most certainly has bugs... but it IS THE MOST comprehensive application development environment ever built. Please note, I said Applications, not systems.
Win32 does not NEED an object model... repeat after me... system API's do not need object models. Would you prefer glibc to be OO? If you need classes, you've got MFC. If you need Components, you've got COM and it's ilk.
I agree, I think MFC sucks... at least for my programming style. But there are LOTS of developers who will disagree. I also feel like programming in PHP is a PITA... but I *love* coding perl (I never said I was mentally stable) To each his own.
Now, your most blatantly ignorant statement: the Windows Security Model... tell me, how log ago did you print out your degree... or are you speaking from years of inside experience? The Windows 'security model' look great on paper, doesn't it? ooooo, domain management, trust relationships, end-to-end encryption... tokens, global admins, profiles.... yep... it's pretty complex. Now imagine how many admins understand the interactions between all the parts and know how to make it work. Now imagine how many 'leet haxorz are out there slipping through the chinks... heck, I routinely slip past the security model of my company's windows network so I can actually work efficiently. To say that the model hasn't been broken is like saying President Clinton did not have sex with that woman, monica lewinski. Even fort knox can be breached if some idiot leaves a window open... and Windows is no fort knox. It's more like a tent with a professionally-printed sign that says 'this is fort knox'
Anyhow, I've gotta go... I'm busy developing SECURE systems for a living.
Yeah, in a few years, the iPod will be eclipsed by some other revolutionary device, just like so many other gadgets before. Maybe microsoft will do it, maybe not... but a cell-phone? I doubt it.

Hear, hear! I have had this book in my desktop library since i bought it eight months ago. While it's certainly too short to truly cover the topic completely, this book has remarkable depth, and is still quite easy to grok. You can read it cover-to-cover or flip around and always find some useful advice. Don't make the mistake of thinking this book is too short to be useful... It's filled with hints and links to more information. Heck, nowadays, all books should be filled with links and references; printed materials too often become obsolete too quickly!
(Normally I'm a grammar/spelling nazi for myself... but I've been coding in PHP all day and I've lost the will to fight for correctness.)
That question is unfortunately both very pervasive and very nearly irrelevant.

I've grown quite fond of the group of people working on integrating KDE with vanilla-Ubuntu. Not only can you add it to an already GNOME-based setup, they've released an entire branch with KDE as the default! They've still got some work ahead of them but the current release is very impressive!
If you want KDE on Ubuntu, apt-get it from the universe repository. Yes, I know, that's less than obvious... The Ubuntu people are working on making stuff like that easier. Heck... when Hoary is released in two weeks (or so) you can just apt-get kubuntu-desktop.
Me? I'm typing this from a freshly installed Kubuntu system. It's purrty. Mepis is nice as well but I've found it's kernel to be a little unstable on my laptop. Nothing a recompile didn't fix, but I've decided to back Ubuntu.
BTW... the wine packages from wine.sf.net/apt aren't stable. Your best bet is to apt-build roll your own. I might contrib mine once I get some font issues worked out.

Granted, I'm mainly asking because you seem to know what you're talking about, but what I want to know is: What hardware is needed for GnuRadio to work?
From the sound of it, it seems like you need an antenna, a tuner, and an a/d converter -- and that's it. The software does all the signal decoding and converting into a format that can be output via screen, speakers, or data stream.
If that's the case, how is it that they claim that GnuRadio can pick up more than one frequency simultaneously? Isn't that a function of the tuner and antenna?
The smily indicates you're joking... Frankly, I think that's exactly why it's required! Certainly, though, there are some major updates and enhancements to the core OS in there.
heh... the atmospheric sciences department at my old university continues to run a VAX/VMS system to this day, though, sadly, because it's so expensive to upgrade it's getting switched to linux.
Anyhow, the weather geeks there had a tradition of sorts, called 'getting hammered', invoked whenever a console had been abandoned... still logged in! They would pull some sort of prank on the poor sap, usually emailing everyone else in the department from his/her account describing how he/she still needs a night-light to sleep or some such nonsense!
At the time, I was dating the weather center director, and somehow ended up with two roommates who were both meteorology majors... I ended up learning some DCL just by watching them, especially since at one point my computer was the only one in the dorm that worked! I learned of their careless little habit and set to work exploiting it...
By writing a script that was executed upon login I faked a DCL prompt that intercepted their commands and absolutely confused the heck out of their poor souls! It re-mapped commands, spit out nonsense error messages, questioned their motives and even mocked them! The best part being that I got to watch the whole time! muhahahah! Just to be nice though it had an embedded command to un-install itself and apologise, heheh!
Okay, I'm through bragging... but just remember, it's not the script kiddies you have to worry about... it's the bored demented programmers!

Isn't this the type of feature that could/should be implemented at the file system level, rather than the shell level? Granted, I don't know how it's done on the mac, but I do know that if you put some files in the trash and then try to open them in any application, they won't open. Any executables in there won't run either. I think the same goes for aliases as well.
Anyhow, now that osx is on a unix kernel I see no reason it can't be implemented, along with revision tracking and perhaps some other nice attributes like package/application association and whatnot. Not to troll, but I have heard rumours that that type of thing will be built into the next version of windows...
I'm beginning to ramble, but I feel like this is a good idea (I've thought of it before, but only recently have I learned enough about the linux kernel to attempt it...)
What we need is a distro with a new filesystem... for now just base it on the standard ext*fs and add the ablilty to include in each file's attributes the package it belongs to, along with the version, et al, and perhaps even the name of the process that created the file in the first place. The extra data wouldn't interfere with any existing software, and package managers/installers could be extended to work with it. (why not? we have apt-rpm now)
A whole bevy of tools could then be created for sysadmins who need to resolve some shared-lib incompatibility or who want to uninstall an app but the rpm database had long been munged, or better yet need to modify the files installed by a package but may want to choose whether to delete (or keep) it after uninstalling!
Yeah, I know all this is already done by existing tools... I've just always felt them lacking in one way or another.:)
ummmm, now I may be wrong, but can't you only download the first *two* CD's of mandrake??
granted, I've had problems with mandrake in the past, but I don't recall there being *thousands* of patches.
