udpeq attempts to solve exactly the latency problem. I've never used it, so I don't know how well it works, but the scheme seems to be this: you have a machine with a fast connection that uses UDP to balance traffic to and from the machine with several connections using UDP streams that get reconstituted on the end box.
You don't use one connection for one purpose. You use all connections for all purposes. Thus you use modem connections to dilute the high latency of the satellite connection toward the relatively lower latency of the modem connections.
I'm not sure how many low quality connections you would need to make online gaming enjoyable under this sort of scheme, but SSH should be usable with a modem or two. I'm not saying this isn't expensive. In addition to the satellite you need a dedicated phone line or two, plus an IP on a friend's machine with true broadband, but for people who live in remote areas, this is a workable solution till they get WiFi.
The point of udpeq is to equalize over several connections, allowing you to benefit from the bandwidth of a satellite connection and the low latency of a modem connection.
You really don't understand what latency is, do you?
I do, simpleton.
A benefit of the app I linked to is getting around satellite latency by pooling modem connections in with it. Modem connections do not suffer from the same latency problems.
You might want to check out udpeq , if you have root on a well connected machine somewhere else. You can use it to combine the bandwidth of several connections.
It is a very poor analogy, if it can even be called one. I wonder what his verbal SAT was.
Because (in general) you can't unlawfully use an ocean front home when buying one is cost prohibitive, there is no analog here.
nonnull function attribute
on
GCC 3.3 Released
·
· Score: 4, Informative
If anyone else was curious to see an example of the new nonnull function attribute, the following is reformatted from the end of the relevant patch, posted to gcc-patches by Marc Espie:
nonnull (arg-index,...) nonull attribute
The nonnull attribute specifies that some function parameters should
be non null pointers. For instance, the declaration:
causes the compiler to check that, in calls to my_memcpy, arguments dest
and src are non null.
Using nonnull without parameters is a shorthand that means that all
non pointer [sic] arguments should be non null, to be used with a full
function prototype only. For instance, the example could be
abbreviated to:
Everyone bangs their drum about how bad things are in the world today. Then they return to their own little world and do nothing.

This is a National Review article, criticizing mainly the legislation put forward by the late Democratic Congressman Bono. Your bias is amusing in light of the point of the article you found "great".
My main concern with moving to a Unix environment is scheduling with MS Exchange. I would need to find an affordable mail server application that can compete if not beat out Exchange Server. Is there such a thing?
Well, for Linux email servers, you could either use an open and free package, like sendmail or qmail. Or if you have an extra thou, you could spend money on something like SuSE Linux eMail Server III.
Let the finance guys figure out the savings, but your options are these:
1. Do nothing. (no cost, no effort)
2. Do something.
2a. Go full-boar Microsoft. (large cost, low effort)
2b. Go with MS Windows and Star Office (medium cost, low effort)
2c. Go with Linux and Star Office (low cost, large effort)
(There are also all the hybrid approaches that are the fractional permutations of the above.)

Decide what makes the most sense for your situation. Personally, I'd be disinclined to go with 2a, because there is still effort involved, but the cost is large. I'd guess that a combination of mostly 1 and some 2c might work well for a normal distribution of workplace personalities, duties and talents, and it would be cheap. Maybe one or two 2a's and one or two 2b's for good measure.
What I think a lot of people are missing is that college is not for everyone. A sysadmin can be completely competent and well adjusted without spending the time and money for college. Just because some of us may have learned most of our social skills at college doesn't mean everyone does. Some learn them at work. Some even learn them in grade school (though nobody here did).
System administration doesn't require EE classes, math classes, breadth requirements, etc. Are these classes valuable to some people? Of course they are.
If the person in question would have just as much fun in life without fufilling the requirements of college, why shouldn't they do that?
Most replies have been of the form: "college is good." It certainly is. There are, however, plenty of good things that some people refrain from and still lead an excellent life.
That said, go to college. System administration isn't as fun at 24 as it was in high school.
There have been people who weld ATX cases together (or AT cases, as the case may be), in order to get more drive bays in front.
You could just as easily turn the top addition around to face the back. That way all the cables going into the drive bay interface will be in the back of the new conglomerate case. The back of the addition (where the other case's power supply would be) would now face the front of the Frankencase, and could be used for ventilation.
Cops lounging while techs execute search warrants doesn't sound like a good idea. Mostly because it is such an obvious waste of time and money. Having law enforcement compensate ISPs (from a fixed budget) for each warrant served would certainly be a more effective control on frivolous warrants than having a cop present.
Not to mention the desire most ISPs likely have to not have a lobby that looks like Dunkin Donuts.
This is the right distinction. CNN is treating the news page as a pallete to paint a developing story on, just the same way anchors repeat the relevant facts of a story every so often for new viewers in a breaking story.
People who know the site will reload the page often if they are interested in the progression of the story. Those who are not familiar with this unobvious policy may consider the story static and link to or otherwise treat it as such.
Andrew Nachison gets it right when he says (above), "[M]ost digital news providers have yet to develop clear standards for how to handle updates and notes about updates..." I've seen this quite often, even on sites run by newspapers.
There should be some way to (either textually or graphically) indicate to the reader that this story is fixed. Maybe just the prevelant use of the word "Developing" in the headline. For now, I usually don't link to news stories unless there is an indication in the URL that the story is archived.
What a dream flat rate unlimited usage would be. Does anyone at Verizon know if these sort of rate plans will ever happen? The Express Network just piggybacks off your normal wireless rate plan.
Seems to me that the oil companies need only roll out that old Hindenberg [sic] film everytime to clinch this one.
Um, that doesn't happen. I know, I know, anything large and rich is bad, but if they are so ruthless at least give them credit for something less juvenile than:
ENERGYCO VP: Johnson, this darn Hydrogen research is really scary. Instead of seeing how we can make money off it as a large energy supplier with an entrenched distribution infrastructure, I guess we should just roll out the ole' Hindenburg clip. That should stop the progress in it's tracks.
When I see "H2", I think "hydrogen." When I see "H+", I think "hydrogen ion" and then "there's an acid somewhere around here". Plain "H" by itself is heroin, just like "X" without the "Window System".

I don't think Doom broke as much ground as you suspect.
MIDI Maze for the Atari ST was the first networked multiplayer FPS I played. That was in the late eighties.
Wolf3D really was the first-of-breed because of the (at the time) realistic graphics, and fast frame rate.
Ah, the old UB. Not to be confused with the less prestigious UCB.

Seems useful, though I suspect many derefernced pointers are set NULL at runtime, and so not spottable during build.
Note: I didn't change the wording above at the [sic], but I believe that this should read "all pointer arguments" instead.
