is to make money. Any money spent in an organization that does not in turn make at least what it costs is a waste. Take payroll for instance, you spend $x / year on a person in return for work that will generate > $x / year in revenue. The same holds for IT. If it can't be demonstrated that an IT budget enables more revenue to be generated then it costs, then good luck justifying the budget. Money is the only metric in business everything from PR to policy to dresscode can be linked to a cash flow. I'm not trying to be come off cold or greedy but those are the facts.
I'll admit i didn't read the article but i have a point to make real fast.
when is the RIAA going wake up to the fact that it is impossible to stop P2P music trading? For every network they kill ( Napster ) the community spawns 5 more. They can moan and cry all they want to congress or whoever but it won't do any good. Lets say ANY hosted mp3 becomes illegal in the US, well then people are just going to move to data havens like sealand (or whatever the hell it was called). My point is the RIAA and others should look at P2P as another market and try to work with it not against it.
what is going upstream from your pc. You can download an eval. version of Iris ( a sniffer ) and see the traffic originating from your pc destined to outside your network.
You might find something crazy going on because a non-serving pc should be pretty quite. You will see broadcasts and ACK's but thats normal. If your computer is spewing traffic and you can't find the source your NIC could be off in the weeds or you may have been hacked (not uncommon with windows and DSL/Cable). I have 38 IP's in hosts.deny because of detected port scanning on my DSL.
10 gig Ethernet is a big problem for all the ATM folks out there. IP6/10Gig Ethernet is a big big problem for ATM. Now carriers have the option of going straight Ethernet throughout the backbone. You say "what about QOS?" well.. IP6 has those bases covered.
i wish i could get weaned off books and only use the Internet for research but i still like having a couple of good books in front of me while i work. My armadillo and crab books are always within easy reach.
your right about book prices, some are just insane. If you're in college then you know exactly what i mean, if not, take a stroll through a college bookstore and check out the price on technical books. Most of my textbooks are between $75 and $120 bucks a pop.
Overall I think you can save about $5 or $10 dollers with Oreilly over other publishers and the material is usually better too.
There is no way i would ever work for people like those three. During the interview process you should know something isn't right when they want you to move into their apartment complex and the fact that they had two apartments used just for weight lifting isn't a good sign either.
The only reason they were able to do the damage they did was because people were willing to work for them. And don't give me any of that "I had bills to pay" story, it was the late 90's, tech work was easier had then a job at Denny's.
yeah replying to your own post is lame but stupid me hit submit instead of preview. so i have basically the same comment twice up there some where. god i feel my one point of karma slipping away..
Every now and then one of the freshman wandering around campus will have an Atari shirt on. hehe, I wonder if they have ever seen an old 2600 in real life. The combat game with the ricochet invisible tanks was my fav.
i remember when i got a 2600. My dad and I played combat ( the one cardridge had like 20 games ) for hours. Every now and then I'll see some freshman with an Atari shirt and it always makes me smile. Rock on Atari!
One of my EE friends made a little device that ran on a couple of AA's and fit in his pocket. IT consisted of a broken off piece of breadboard an IC and some loops of wire. He said he could cause all cell phones around him to hang up when he "pressed the button". I think he said it was illegal to own one and it could mess up pace makers too. The guy was kind of out there, most EE's are, anyone else heard of this kind of thing before?
There are situations where increasing the bandwidth in a network can actually decrease performance. say you have some routers working hard to keep up with 10Mbit links.. you say.. "sure wish my net was faster" so you upgrade to 100Mbit. Now the routers are freakin out and dropping everything left and right and throughput is actually going down instead of up.. and now your fired too.
Better hardware and better protocols (ATM comes to mind) can go a LONG way in stopping jitter (variance in delay) and decreasing delay. I think this is AOL's thinking with this new switch.
I think that holds for the Internet in general. It is really just a medium, no difference between good and bad, it is up to the user to make that distinction.
I didn't get any pats on the back for fixing an open relay but I did it anyway because *I* know it was the right thing to do.
On the Internet your own belief in right and wrong are the only things that will influence your behavior. The Internet is still kind of like the wild west where the Law is few and far between and no one is there to force you to act in a law abiding way.
I would think the last thing the RIAA or most any other non-technical or even technical organization would want to do is go head to head with the net in what amounts to a hack war.
If this bill came to pass and some company stated publicly that they are participating in trying to disrupt a particular service of a P2P network then they have just placed a giant bullseye on themselves.
i wonder if the DOD will want to use their nuke simulators on the earth simulator to simulate a nuclear holocaust... my guess is they probably don't want to know.
i played with win2k pro. server a while back and came away pretty impressed, more so then with any other Microsoft OS. The networking stuff that has been added/revised is pretty rad and the built in telnet server is cool too ( provided it is used wisely ). I still run strictly Linux servers (file and DB) at my job but if i got into a position where Microsoft absolutely had to be used I wouldn't panic.
10 gig ethernet really only makes sense in long haul, heavily utilized backbones. Which is funny because Ethernet isn't all that great of a WAN protocol ( in case Mr. Metcalf is reading, yes i know it was originally intended only for LANs ). Its great success is mainly due to a sharply falling price curve. ATM as a protocol is head and shoulders above TCP/UDP+IPV4+Ethernet with respect to the WAN but it costs more. Until IPv6 with its enforced QOS and flow labels is widely adopted I don't see Ethernet doing alot in the WAN.
well on congested links a smaller packet size actually works better, thats why ATM cells are only 53 bytes in length. Also, when 2 or more interfaces are on the same collision domain the 1500 byte MTU is required for collision detection assuming you want the max. link length to remain the same.
I would guess that if they maintained the same MTU it was to "cover all the bases". You can do some tuning for a specific LAN like messing with window sizes and MTU's to get optimal performance for your particular case.
I wonder if this could be used for error detection on long links. Like maybe have the checksums verified every so often. If the wire itself could drop a corrupt datagram it would save the devices on the endpoints some effort. The upper layer protocols wouldn't care, all they know is that a datagram was lost which they can handle.

did anyone read Henry Spencer's post? Isn't he the guy behind FreeSWAN (among other things)? what was he doing in the zoology department...

hehe yeah they are going to be seriously ticked when their missile systems are "not responding"
