"TCP throughput is inversely proportional to delay"

Absolutely wrong, 2Mb/s at 1ms delay gives the same throughput as 2Mb/s at 10ms delay As long as the window is large enough

Actually it is correct. The throughput is equal to TCP's congestion window divided by the round trip time (end to end delay), or TP = CWND/RTT. What he means is that assuming the window size is the same, the throughput is inversely proportional to delay.

Old-School Keyboard Makes Comeback of Sorts 519

CharlotteShma writes "Some old writer once said that in order to keep going, he needed to hear the scratch of the pen on the page. Some self-proclaimed keyboard aficionados would make the same argument for computer keyboards. Is it possible that the old 'clicky' keyboards are making a comeback? Now that we've replaced the old buckling springs with rubber domes, our keyboards are only getting quieter and quieter. According to the people at Unicomp Inc., all keyboards made since the early 1990s are, frankly, no good. They still use and produce vintage IBM Model M keyboards in their small factory in Lexington, Kentucky. The IBM Model M keyboards are ugly, built like tanks, and, most importantly, have a spring under each key which clicks when you press it." Not sure what's ugly about them — most other keyboards are ugly, when you shut your eyes.

Linked In Or Out? 474

Mr_Whoopass writes "I am the IT Administrator for a regional restaurant chain, and as of late I am noticing more and more people sending me invitations to sites like LinkedIn, FaceBook, etc. Mother always taught me to be a skeptic, and, knowing more than the average Joe about how information can be used in this digital era, I am reticent to say the least about posting such personal details as my full name and where I work on the net for all to see. I have thus far managed to stay completely below the radar, and a search on Google has nothing on my real persona. However, now times are tough, and I see sales dropping in the industry I work in as it is a discretionary spending market to be sure. I wonder if I should loosen up on the paranoia a bit and start networking with some of these folks in case of the all too common layoff scenario that seems to be happening lately. What do other folks here think about this? I am specifically interested in what people who work in IT think (since I know that just about every moron who has 'Vice President' or sits on the 'Executive Team' is already on LinkedIn and has no clue about why they should be trying to protect their identity)."
