Sigh, No one really remembers coaxial Ethernet details any more.
You need to terminate into 50 ohms as Ethernet uses an AC component for signaling and a DC component for collision detection. If two nodes try to transmit at the same time, the DC offset passes a trigger value and a collision is signaled.
Even if the link is point-to-point, coaxial Ethernet needs working collision detection for cases where both systems start talking at once.
Hmm. I just checked on the rating of AT&T (then Cingular) wireless in Consumer Reports surveys from prior to the introduction of the iPhone. It sucked then and it sucks now. And the old AT&T Wireless was worse. (It actually used TDMA!)
But pointing the finger at others was traditional at Ma Bell in the old days and it has not changed.
In my years in radio and networking prior to the AT&T breakup, no outage was EVER their fault.
Surveys regularly report that Verizon has best coverage in almost all major markets and has by far and away the largest 3G coverage. The bottom of the list is less uniform, but Sprint and AT&T are generally at the bottom. T-Mobile is usually in hte middle, but seems to be improving.AT&T has minimal 3G coverage, but it generally performs well. when available. SF and NYC are reportedly capacity limited.I can only speak for the SF area where it does get rather slow from time to time.
One issue with Sprint and Verizon is that they are CDMA and generally not compatible with systems in other countries. Sprint is advertising a phone that does both CDMA and GSM, though I have no experience with it.
I can't comment on plans as my employer deals with that end of things.
I'm sorry, but the original Arpanet did not have ICMP or pings. This was years before the invention of IP.
I am not sure if it even used 8-bit ASCII. Many, many systems of that day were 6-bit ASCII (no lower-case letters) or EBCDIC. A "word" could have been 12, 16, 18, 24, 36, or 60 bits. (There were MANY other lengths including 1 and 29, but these were oddities.) Note that most of those were multiples of 6, so 6-bit ASCII was the more common unless it was an IBM Computer. I suspect that this initial use lacked anything that could be called a "protocol stack", but I was still in high school and thought the Arpanet was there so I could play Zork on the ITS systems at MIT, so I am far from sure.
Now, 40 years later, I'm pretty sure I was right about the reason for the Arpanet.
Just for the record, the University of Southern California is NOT a public school. It is and always has been a private school It is not associated in any way with the University of California. I hope that my employer would not be a party to such a politically embarrassing statement.
The use of goats for weed control is fairly common in the SF Bay Area. I often see them munching away at various hill-sides. At work (no, not Google), they have been regular visitors for years and several farmers rent out their herds for this.
Amazingly (at least to me), I have seen a goat munching away on leaves of a tree WHILE STANDING ON A BRANCH of the tree. I have no idea how it got up there, but it seemed totally unconcerned with its location.
I just got back from the ARIN meeting this week and the letters are, indeed, a "scare tactic". Network providers keep reporting that PHBs won't spend any money on IPv6 even though engineers are begging for it. Most corporate officers probably think IP is only Intellectual Property and this is an attempt to draw their attention to the fact that the network world as they know it is going to end soon and that the only way to avoid serious problems is to either stop growing or to start IPv6 deployment.
PHBs sometimes get the idea when they realize that not spending some money will lead to big problems in a few years. Others figure that if it's over a year away, it really does not matter because it won't impact their bonus this year, so it may not work, but we can hope.
Yes, this a a nit, but one that I am seeing more and more often.
The entry refers to Rome in "320 AD". This is simply wrong. It is AD 320. Any of you who posted Latin comments are aware of this modern mangling. 320 Anno Domini simply does not make sense. (See Wikipedia article on "Anno Domini".)
As with all issues involving time, it's pretty bogus, anyway, so perhaps/. should just use CE (Common Era).
I can watch YouTube on my FreeBSD system just fine. This is probably using the older Flash v7 plugin or, maybe the mplayerplug-in, but it does work just fine. There is also a gstreamer plugin for YouTube. Note that the Flash V7 does require nspluginwrapper to work with FireFox.
These are not a solution to the Flash on Unix problem, but it is a solution if all you want is Youtube on FreeBSD.
The correct answer is to use jail(8) for security. That's why they exist and what they are intended for.
Does Linux have jails yet? Maybe you need to switch to a BSD based system.
