So far as I know, no NAZI ever ate Jew Stew. Something usefull came out of that food (ITS FOOD!). Not the only difference, but a long shot. But a difference. They are not the same thing.
QNX is a general purpose embedded OS. If I know my history right, what became Cisco started out as a project at Stanford - to build a purpose buit router hardware/software combo.... IOS has 20 years of developement to be a router OS. Its not something they hacked together over a weekend.
FGA: Perhaps they are correct. Perhaps SMTP servers should be less anal about HELO/EHLO's. But many are, and we are talking about reality: how things actually are, not what the standard says, or what a better standard would be... Part of their argument is that given the state of the world, neither the SMTP client or server has a compleate view of reality, so judging the peer based on their view of reality is flawed... If we are building a replacement to IP, then we want to build one where peers can have a valid sense of reality, no?
On addresses: looking at '821: yep, pretty liberal on what it accepts as an address. But, same argument as above; while (almost) anything is valid under 821, many MTAs and MUAs would likey get confused if presented with anything that a laymen wouldnt recogonized as an email addr.
My point still stands: while in theory SMTP could run over things other then IP, and for that matter carry things that are not 822 messages, for 15 years it hasent, and current implementations make assumptions based on the set of {IP, SMTP, 822}.
Cisco is very popular. But their popularity has yet to reach monopoly status. There have viable competitors. While there are more then a few Cisco propritatory protocols, generaly speeeking, they came out before a industry standard did (LAN trunking, VLANs over trunks.....). When the standard comes out, Cisco generally supports it. (even if in the case of IPv6, rather slowly). So they do support standards, before they exist, in a sense. It is entirely possible to do networking things without using Cisco products, without compromise. The same can not be made about Microsoft (doing desktop things).
If the protocol assumes a connection and does not depend on it being anything in particular (technically: if it's an appllication level protocol), than it'll sit on any connection oriented protocol. That's exactly what the ISO layering is supposed to mean.
Prehaps that is what it is supposed to mean, but two things
- IP and friends came out long before ISO and their layer model. IP is based on the DOD model; and while DOD has less layers they dont exactly match up. Not really important, however
- SMTP uses lots of things that assume IP. HELO/EHLO wants a hostname, and usually one that can be resolved to the address that the connection is from. From (in SMTP), From, To, CC, etc in RFC822 expect either UUCP routes, or IP hostnames. Any MUA written after 1990 would likely get confused if presented with a UUCP route.
New stuff
Cisco came out with IPv6 around 3 years after everyone else did, including Microsoft (Research). While a p120 with Linux is just fine in your apartment, and Cisco has competitors, Cisco not supporting something (relevent to their product line) means it wont become wildly used.
- You don't necessaraly need new hardware, but routers are heavily optimized for dealing with IP sized data chunks.
Upgrading endpoints v. backbones: lots of people are running IPv6 over v4 tunnles. Im willing to bet there are exactly 0 production, commercial, IPv6 backbones. New things happen on the edges.
Five years is a very short period of time. The reason why IP is in use is because it works. There are more then a few system that are "better" on paper. IP has been proven to work, and is the only protocol to acheive its level of sucuess... v6 is in the process of being proven (and refined)
... Because only people who are "Big Wheels" have that access. While I get the joke, its not much of one at all. OTOH, I also get "UNIX". UNIX: the OS based on not very funny jokes.
Ngage is Novell Corps consulting, training, support wing. Obviously, Novell will consult, provide training and support for eDir. extend is somewhere beteween a Web Portal product, a Web library... General webyness. It (can) heavily use(s) eDir. nsure is one "usefull" layer on top of eDir. Apps to define workflow, policies, etc etc. eDir is the database, nsure is the middleware. High level stuff using eDir as the backend. nterprise is (another) "usefull" layer on eDir. Or a collection of usefull layers. Looks like all relativly low level stuff.
eDir remains eDir. It only changed its name once., and it wasent retroactive to NDS.. Though NDS/eDir version numbers are the same scale, and always increasing. (As opposed to Sun, SunOS/Solaris and their random version number scheme).
You are confusing things that use eDirectory, both with each other, and with eDirectory itself.
Im neither a EE, nor do I have paticularly good "low level" programming tasks. That said, my Uni ASM course was on a IBM mainframe, and I use VMWare regularly, so I know a bit of the practical side of things.
VMWare, in the workstation and GSX version, runs on top of a host OS. ESX is its own "OS". In the IBM world, the VM "OS" layer is very specialized and so far as I know, used for just allocating resources to VM instances... The hardware helps a lot in this case as well.
Idea: What would be the possibility of a "Meta" PC hardware/OS platform? Possibly having zero reselblence to PCs of today, no PC compatable BIOS, N/S bridge concept gone, etc... The hardware, and a thin VM managemnt OS works together to virtualize the hardware, making it appear to be a PC to the VMed OSs.
The other couple of replies touch on the subject, as if it is a joke.
But porn has pushed more then one technology.
Internet wise, early streaming video technology (VIVOs) were used almost exclusivly with porn sites.
(Multi-)Tiered marketing, while not unique to the internet by any streach, was perfected by porn sites. Brick and mortor sales contracts would be pagest thick and require lengthy sessions with lawyers.... Online it is just a few clicks away. "Clearing houses" of marketing programs are almost definitly unique to the Internet, and they started out with porn.
Well, light doesnt travel at full speed through fiber.. And electrons even slower through copper. And lines are not straight. Add in a bunch of router hops, and you do get latency. At least more then on campus.
He was talking about bandwidth, but he meant bandwidth+latency.
The handle display/formating/. You can send exact positioning data to a vt102 (and you would)... But you send something more akin to HTML to a 3270.
And they handle data input. You can have fields that hold more chars then fit on the screen.. That kind of processing is done client side. You send data back to the 3270 controler a screen at a time. 3270s are the reason why there is a distinction between ENTER and RETURN. ENTER enters the data into the controler, RETURN does what a carage return does on a typewriter. All these PC keyboards are mislabled.
Conceptually, a DEC style terminal is like, well, ssh. A 3270 is like HTML/HTTP.
On your old networks, the client/server were likely in the same building, or at least on the same campus. Either way, connected via ethernet, with only hubs and bridges between them... Network layer devices or below.
These days, even going accross campus, your going to hit a bunch of routers which add latency. Going physcially long distances... light can only travel so fast.
.... Or do you want a different reason why the grandparent post was modded a troll? It doesnt need any better reason then that.... You yourself recogonize the topic as being "crap".
BSD does not insure that what people create and then desire to be free, remains free. There are both philosophical and commercial reasons why this "restriction" can be desireable.
Bull fucking shit. The BSD grants specific things. GPL grants different specific things. If a given programmer releases things under the BSD then that is what he wants. The choice of license is up to the programmer. If you want things to "alwas be free", then choose the BSD. Who is forcing people to choose BSD?
Those are preprocessor directives. While preprocessing is done automaticly, not even with a sepearate program, with GCC, this is recent, and atypical. You can force GCC to run only the preprocessor phase if you want.
I cant see any reason why you couldnt put in #ifdefs in a.java, and run it through gcc -E first.
Anyway. Java is supposed to get rid of the necessity for #ifdefs. If you find yourself needing #ifdefs in Java, then either you need to get a better Java book, or Java itself is compleatly broken.
Because he equates Open Source with Free Software. Which is a mistake that was acceptable in the 20th century, but today is inexcuseable. He therefor must either be a moron (which there is not a moderation effect for), or a troll.
