Indeed. I can't help but thinking are just jumping on a bandwagon here , one which has a couple of flat tires too. Sure HP have invested a LOT of money in Itanium but to dump PA-RISC which is their cash cow in the server market at the moment and has had billions invested in it too seems pretty damn premature to me. But then we all know that top execs tend to default to sheep mode when they can't make a decision and I think thats whats happening here.

XML is designed to represent data. Trying to shoehorn a procedural and OO programming language into its format is a recipe for disaster and thats exactly what these guys have come up with. Its long winded, ugly and hard to read. I really can't see any programmer wanting to work with this. There was a reason netscape invented Javascript , not some form of procedural HTML. Still , at least this language will be a lesson in how not to design one. Expect this language disappear fast except for a mention in comp sci compiler/interpreter text books and the occasion far flung outpost of masochist coders.
Did a company as large as Cisco seriously have no appropriate troubleshooting equipment on the WHOLE of the east coast or anywhere closer the california? What kind of mickey mouse support outfit are they running??
Any good C programmer would have done OOP in C (maybe without knowing it) before he switched to a "proper" OO language. Some aspects of OOP are easy in C , eg by using function pointers in structures to mimic methods and inheritence. The problem learning OOP languages is more due to their appalling design and syntax, I mean was Bjarn on drugs or something when he came up with the C++ template syntax?
7 bits was used when the ASCII character set was initially devised (though 4 bit had been used before that) with the 8th bit being used for parity checks. At some point someone decided to hell with parity checks , lets use the 8th bit to double the number of characters available. And once 8 bit became standard in hardware then 16 bit narually followed as you could still divide a 16 bit word in 2 to get 8 bit characters. Similarly with 32 bit you can divide a 32 bit word to give two 16 bit words and hence can run 16 bit software on 32 bit hardware with a bit of help.
Thats the gist of it anyway.
Wrong. Message recieved reciepts are not part of any protocol though they can be implemeted by various mail servers. Not all servers or clients support them though. Message read receipts are a client only function (obviously) and since these can be switched off spammers usually used HTML tags to implement this functionality. Easily defeated if you use a client that doesn't support HTML.
The bit about the 2 romanian programmers writing something that will pop up messages on your screen. How will that work exactly? Is he being taken for a ride (we can only hope) or are these romanians going to exploit a bug in Windows (unix is safe unless someone is dumb enough to allow all hosts access to their X server) in which case it will be a crime and this f*ckwit can be busted for hacking?
Yeah you're right. Still , even that solution raises interesting issues for broadcast protocols such as IGMP. Personally I think breaking a protocol to fix a broken OS (windows) is a waste of time.
Umm , buffer overflow attacks on vunerable UDP services? Ok ICMP could be more of a problem but there are lots of other less used protocols whose servers are running as admin/root who could yet be susceptable to these attacks. Email isnt the only way for these things to spread you know.
Since only TCP has the idea of connections only this protocol can be protected from abuse in this way. Others such as UDP/ICMP etc send their data in descrete packets (as far as the OS is concerned, whether the app client-server system has the idea of connections over UDP is another matter) and if you limit these to 1 packet a second you can kiss goodbye to a whole host of protocols because they simply will not work effeciently or at all any longer. All his idea will do is cause virus writers to use protocols other than TCP. For macro viruses this could be a problem (does vbscript support UDP?) but for exe viruses its no big deal I suspect.
...you'll get bitten eventually. Its a shame for these guys and somewhat shortsighted from MS's point of view as theres a chance they could alienate a large number of developers, surely the last thing you'd think they'd want to do. But as has been proved in the past MS only thinks about the bottom line, ie $$$$, and external developers don't shift Windows and Office in bulk.
I assume that by robust you're not taking the reliability of the VM into account , because reliable they aint. And they're slow , and they hog the CPU , and not all java code is portable,
and Java is just C++ with some of its powerful features removed (though they're slowly adding them back). Apart from that , yeah , Java is a great language compared to C/C++.
I'm afraid you need to go do Science 101. The amount of heat put out by machines and all living things put together is miniscule compared to amount of heat coming from the sun and being trapped by the atmosphere. If we didn't have any greenhouse effect the earth would be about 20C colder. So what exactly do you think doubling the CO2 content in the atmosphere is going to do to the global temperature? Quite.
The question isn't whether we'd destroy the planets enviroment completely (unlikely) but whether we could damage it enough to make the current human population unsustainable (very likely) due to drowned land , drought and/or flodding causing food crops to fail. The asteroid that supposed to have hit the earth 65 million years ago wasn't a big deal to the planet as a whole but it didn't do the dinosaurs any favours did it?
Yeah , anything you';d use ftp for

Unlikley I admit but the potential is there.
P2P is basically the old archie protocol combined with ftp , whereas archie searched for stuff and told you where it was but didn't go get it , P2P does both.
Couch potatos never complain of these symptoms therefor I propose that all VDU's must have no
greater resolution than 625 lines (525 in the US) and a refresh rate no greater than 50 Hz (60 Hz). Plus companies must provide seating at least 10 foot away from the computer with keyboard & mouse cables long enough to cope. Problem solved. Obviously this would cause other problems such as users wondering why they can't order pizza and have it delivered to their desk and why scratching their nuts gets the female staff so angry but these are minor issues...

Yes, and they didn't use patterns either. YOu think they were used in the design of the original unix, vms , os400 , macos? Get real. And I agree OS and app software and not close to being the same , OS software is a damn sight harder to write.

Actually we use C++ and Java at my current place , plus genetic algorithms. If any programmer was clueless enough that he needed to read a book like this before he could write decent code then we wouldn't hire him. We want people who can think for themselves , not just regurgitate what they've read in some Dummies Guide to Software Design type book.

In other words it was so unfunny in the first place then anything would make it funnier. Kind of what I suspected.
