If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...

If you have a not-so-usual solution for your problems but need to justify it to your boss...

If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...

...then 'No Bugs' Hare on Soft.ware might be the right place for you.

Your mileage may vary. Batteries not included

For most of us, programming (or more generally – software development) is all the life is about.

IT Hares are not different. And they have more than just quite a few bits to share about programming…

(Almost-)Zero-Additional-Latency UDP-over-TCP

Quote:	“we realize that for some of the Clients – UDP just doesn’t work because of some weird firewall between Client and Server”
Another Quote:	“there is nothing to block us (so head-of-line blocking doesn’t apply)”

Quote:	“Nagle’s algorithm aims to deal with those [CENSORED] developers who’re trying to send data over TCP in really small chunks (like 1 byte each time)”
Another Quote:	“it seems that “proportional rate reduction” (PRR, reportedly used by Linux kernels by default starting from 3.2) performs for gaming purposes a little bit better than the alternatives”

Quote:	“the best we can hope when using a single TCP connection over 5%-loss channel – is having 1.5-second “lag spike” every 5 or so minutes, and a 3-second “lag spike” every 2 hours.”
Another Quote:	“we may already have the-information-we-need on the receiving host – but this information is hidden from us by layers of abstraction on receiving side”

Another Quote:	“It is very important to keep updater transaction-oriented.”

Quote:	“Strictly speaking, for real-world computers, every algorithm which completes in a finite time can be said to be O(1)
Another Quote:	“now the difference because of unfortunate ‘jumps’ over (uncached at the time) memory can lead to a 100x+ (!) performance difference. However, it is still O(1) and is rarely taken into account during performance analysis”

Another Quote:	“if there is a NAT device on the way from your Client to your Server – a sudden IP change can occur with absolutely no notification to Client whatsoever.”

Quote:	“All the routers, switches (actually – pretty much each and every device which forms Internet infrastructure) – are allowed to drop each and every packet.”
Another Quote:	“TCP, when it observes a dropped packet, interprets it as an indication of congestion – and slows down.”
