UDP
Funny how we keep referring to UDP as a "protocol" on the same category as TCP. Have you ever looked at UDP?
It's two port numbers and an optional, deprecated checksum. That's literally all that UDP adds to your packets.
In any other format these would be considered optional fields, not a separate protocol worthy of its own name.
UDP over TCP?

Def: 9A set of formal rules describing how to transmit or exchange data, especially across a network
A simple one, but a protocol nonetheless

Right. The only thing you need is a way to detect errors and to check whether the packet is meant for you.
And that can be done using a... hum... huh... a previously agreed set of rules.

My understanding - which could be entirely off-base - is that the original ARPAnet protocols had lo layers, just ARPAnet Host-to-Host Protocol for simplex (i.e., unidirectional) data flow, and Initial Connection Protocol, which created a pair of AHHP connections between two hosts and managed the connections. Originally, there was no equivalent of a Transport layer; each program was expected to work out their own methods of communicating using ICP and AHHP.
This quickly proved to be unworkable, so a kinda-sorta Transport layer protocol, Network Control Program, was introduced. As the name implies, it was originally a program that other programs invoked to do the transport for them, and it consisted of a pair of simplex ports to give the effect of a duplex connection. It was both too simple (having no error correction) and too complex (because of the paired ports arrangement), which is why the full-duplex TCP and UDP were developed to replace it.
The original idea, as I understand it, was that Tramsmission Control Protocol would be used for mission-critical control messages, such as the handshake stage of a Telnet connection, while User Datagram Protocol would be used for the actual data transfers. However, as TCP was developed, the idea arose that it should act as a connection rather than sending individual messages back and forth, while it was agreed that UDP should be used for any one-time, host-to-host data transmissions that didn't need a continuous connection - which was expected to be the primary use case. It was assumed that connections would be used mainly for program control, and that error correcting for data transmission would have to be handled by the user software anyway as the assumption was that the programs would need to check for malformed data, anyway, so it made sense to push checking for transmission errors would be on them as well. Similarly, it was thought that connections would be something that would be better handled on a case-by-case basis, as it was expected that different network services would need different connection rules.

@OffByOne More like someone rediscovered Buddhism, again. Happens from time to time, under names such as Gnosticism, Sufiism, 'Satanism', or any of several other things. Philip K.

I used Gopher for real for a while back in 1992 when WANs were still a bit too slow for the WWW to be quite usable. Gopher was not easy to use, since it tended to lead to information being arranged purely hierarchically. The clients of the time were also butt-ugly, so much so that we ended up using this weird heavyweight Motif app (called NCSA Mosaic) for the job as it sucked less than the alternatives. Then we got a network upgrade, discovered that HTML was a great idea, that HTTP could work better, and that true hypertext was better than a pure hierarchic tree.
Search sucked utterly on all systems until the first good web crawlers appeared (Yahoo! of the time only worked well for people with conventional interests), and Google when it arrived was amazing as it would manage to put the link you wanted as the first link instead of 10 or 20 pages of results in. They really did change the world.

A Hot Month for Clinton’s Body Count
Article makes a case for Clinton being a mass murderer. I'm sure a lot of these individual incidents would fall apart under scrutiny, but God, there's so many of them.
Either way, it's fun to speculate. I'd definitely watch a version of House of Cards with Clintons as the titular duo.

In 2011, Smartphones are ubiquitous and everyone and his dog is writing mobile apps, but using apps when you're not in range of a fixed wifi hotspot or standing still in an urban area is often extremely frustrating. How often have you tried to refresh and found yourself staring at an interminable spinner that makes you want to throw your phone at the wall? Here's why (and a plea to app developers to do something about it!)
Yes! I'm not crazy!

Why mobile apps suck when you're mobile (TCP over 3G)
IME, if the phone's connectivity indicator says “H+” (or I'm on wifi) then things are fast, “H” then things are OK, and anything less sucks. Particularly as I'm probably dropping into a signal blackspot at that point anyway (the route has a lot of tunnels and deep cuttings, and O2 are a bit shit anyway).

This is a bizarre one. It all started when the internet seemed to go out at my house. My desktop, phone, TV, everything stopped working. The usual solution at a time like this is to power cycle the modem and router. While this fixed the situation temporarily, soon after the problem returned. What made me think this was more than just ISP flakiness was that for some reason Chrome actually locked up; good ol’ Windows “this program stopped responding” so like any enterprising engineer I busted open Wireshark...
