I remember watching a documentary on UK television describing one of the theories as to how water came to be on Earth. It was proposed that much of the ocean's water came from comets that pelted the Earth before there was an atmosphere and with the Earth being the right distance from the sun, we got oceans (instead of steam on venus and ice(?) on Mars). It has also been suggested that the building blocks of life (amino acids etc.) may also have come from extraterrestrial debris.
Could it be that without an atmosphere on Mars, comets and the like could be falling on the planet and depositing their contents on the surface in the same way as has happened on earth? I mean, heck, we've even got our rover planted in the midst of a crater created by extra-martian debris and since there is little or no erosion on this planet we could be partly examining the contents of extra-planetary material. Personally, I think this would make the examination even more interesting than it already is!
My standard reply to this is that there are 2^128 possible hash sums which is many magnitudes more than the number of electrons in the universe! So you'd have a pretty hard time storing them all.
As for the set of short strings, because this is such a limited set, if MD5 is any good (which it is), you won't find a collision in such a small subset.
Parent is modded up as funny but surely this is the whole point?
VoIP is a product you can obtain, buy the product from the shop or get an open source version. "Voice will be just another form of data" as the VoIP makes use of the data transfer service that is the internet. It just so happens that the end user cost of the internet service is free at the moment. One day, I expect to see the internet provided like a utility service as we get electricity.
5% of all windows installations crash two or more times every day
A very clear distinction is - Is it the OS falls over two or more times every day (equiv kernel panic) - A error report is sent to microsoft (so more than 5%) - Error reports caused by OS falling over? - Error reports caused by *any* application crashing? (equiv, app seg fault)
I strongly suspect it is the last. I.e 5% of all windows machines send an error report every day that some application or another has crashed. If that's the case, that's not a reflection on Microsoft Windows.
That looks like what SCO is trying to do and it will probably to work to a certain extend

Q. Can Microsoft sue CodeWeaver's customers for using Wine? A. Not if you license Wine from CodeWeavers. One of the protections you receive as a customer of CodeWeavers is that you are licensing Wine from us. We warrant that the product you are buying from us is legal. If it isn't, the term of your license agreement with us says that we are responsible for its legality, not you.

# currently there isn't a mature messaging server and MSMQ is not appropriate for high load messaging platform. It thought MSMQ is guaranteed messaging? Guaranteed messaging is not appropriate for high load messaging. You need to look to best effort messaging technologies. This is not a.NET issue
# SOAP is too damn heavy weight to scale well beyond 60 concurrent requests for a single CPU 3ghz system. That's not a.NET problem really.

That said, where we are, Oracle is used as it was judged to be more cost effective and that SQL server should not be used in mission critical apps.

They aren't suing people who are possesing the MP3s nor those who are (possibly/probably/definitely) downloading the MP3s. Instead they are suing those who *distribute* MP3s without permission from the copyrightholder. You don't, I hope, fall into that category.
But do you have to use all the new complex features?
Besides, if the answer is that you must use these new features or doing X isn't easy, might that not suggest the new feature has made life simpler for developers?

Here is a use: Java components are very easy to reuse in GUIs. I *hope* that the API is such that I can easily embed this browser in any application I may choose to make and hopefully it will be easy
On the flip side, how easy is it to embed the mozilla into my own program? The Mozilla ActiveX control is pretty good but it is Windows only. I'd love to be able to write my cross platform java GUIs with an embedded web browser. Could this be the best way?
Where I work, they made a point of this: Open source software is only bought from big companies with money. That way, if any lawsuits appear, they won't be directed at us the client but at the vendor with money, thereby protecting ourselves. With companies like Sco about, lawsuits against open source programs are seen as a genuine threat
The argument about not touching OSS is correct. Where I work we have a policy that we may not use OSS at all unless we buy it off a large vendor with money (Redhat, Borland etc). Then if something goes wrong there is someone to blame. If there is a lawsuit surrounding the program, that also goes to the vendor.
I don't know about you but I've never seen anyone at work ever write a virus in an in-house app to be used in-house. I don't think one would need to be worried about that.
On a more specific case, in some places, it is the ease of which one can customise Excel through VBA that is completely unrivalled in any other office suite. The use of VBA becomes a necessity for the business and to switch requires an alternative. Even if VBA were rivalled, the lock in of VB makes any switch very difficult
A very succinct explanation I got while on a.NET training course was that.NET reversed something that Microsoft got wrong:
COM: A very lightweight wrapper for intra-machine communication. Low overhead and fast. Forces programmer to handle all other issues like memory management, implementing interfaces etc. etc.
COM+: A heavyweight framework for inter-machine (remote) execution. Tries to do all things and as such suffers from being ghastly to set up and use
In short COM: Light for local machine execution COM+: Heavy for remote execution
Microsoft decided they got this completely wrong and have reversed it
dotNET local machine: Uses a CLR and common type system. This handles all memory management etc. etc. inside a virtual machine making things easy for the coder (with overhead of course)
dotNET remoting: Has become very lightweight. You just send XML soap messages over TCP. That's light and that's also what web services are based on. Can you imagine even considering web servicse with COM+ ?
So that's what they've changed in terms of COM/COM+. Having used it, I'm glad I never have to touch COM+ again and I'm glad that Microsoft have realised that a java style CLR/VM works well for general programming
Parent was: Office is the most popular productivity product because it's good

Milestone target: Running .NET over Wine

It's not as bad as you make out. The.NET CLR runs on top of the Win32 API and is not a replacement. Therefore, in theory, a fully working WINE will allow.NET to run straight on top of WINE. In fact, there are attempts in the Mono project to use WINE to enable WinForms on Linux. If.NET can run on WINE, that would be a major achievement and it certainly isn't impossible
My quick scan of the article got to "Cablevision said it is scrambling to eradicate the bug". So you will be able to resume recording your favourite programs once we have succeeded in scrambling the broadcast signals? Well, at least this avoids the analog loophole. Anyway...
