HEADSUP: Change of Makedev() Semantics on FreeBSD
Dan writes "FreeBSD's Poul-Henning Kamp is in the process of adding ref-counting and locking to dev_t, and would very much prefer if this step is completed soon before 5-STABLE gets branched. He says that all this will be transparent to the majority of device drivers, as the refcounting will happen in the make_dev() and destroy_dev() family of calls and normal drivers need not know more about it."
It's an evil plan I tell you. They post this random stuff that affects possibly 1 out of 100'000 slashdotters on here and dare call it a topic. Then I make a perfectly reasonable Simspons comparison between the headline (HEADSUP) and Ketchup (CATSUP), and they mod me as troll... tsk tsk tsk...

What We Can Learn From BSD
By Chinese Karma Whore, Version 1.0
Everyone knows about BSD's failure and imminent demise. As we pore over the history of BSD, we'll uncover a story of fatal mistakes, poor priorities, and personal rivalry, and we'll learn what mistakes to avoid so as to save Linux from a similarly grisly fate.
Let's not be overly morbid and give BSD credit for its early successes. In the 1970s, Ken Thompson and Bill Joy both made significant contributions to the computing world on the BSD platform. In the 80s, DARPA saw BSD as the premiere open platform, and, after initial successes with the 4.1BSD product, gave the BSD company a 2 year contract.
These early triumphs would soon be forgotten in a series of internal conflicts that would mar BSD's progress. In 1992, AT&T filed suit against Berkeley Software, claiming that proprietary code agreements had been haphazardly violated. In the same year, BSD filed countersuit, reciprocating bad intentions and fueling internal rivalry. While AT&T and Berkeley Software lawyers battled in court, lead developers of various BSD distributions quarreled on Usenet. In 1995, Theo de Raadt, one of the founders of the NetBSD project, formed his own rival distribution, OpenBSD, as the result of a quarrel that he documents on his website. Mr. de Raadt's stubborn arrogance was later seen in his clash with Darren Reed, which resulted in the expulsion of IPF from the OpenBSD distribution.
As personal rivalries took precedence over a quality product, BSD's codebase became worse and worse. As we all know, incompatibilities between each BSD distribution make code sharing an arduous task. Research conducted at MIT found BSD's filesystem implementation to be "very poorly performing." Even BSD's acclaimed TCP/IP stack has lagged behind, according to this study.
Problems with BSD's codebase were compounded by fundamental flaws in the BSD design approach. As argued by Eric Raymond in his watershed essay, The Cathedral and the Bazaar, rapid, decentralized development models are inherently superior to slow, centralized ones in software development. BSD developers never heeded Mr. Raymond's lesson and insisted that centralized models lead to 'cleaner code.' Don't believe their hype - BSD's development model has significantly impaired its progress. Any achievements that BSD managed to make were nullified by the BSD license, which allows corporations and coders alike to reap profits without reciprocating the goodwill of open-source. Fortunately, Linux is not prone to this exploitation, as it is licensed under the GPL.
The failure of BSD culminated in the resignation of Jordan Hubbard and Michael Smith from the FreeBSD core team. They both believed that FreeBSD had long lost its earlier vitality. Like an empire in decline, BSD had become bureaucratic and stagnant. As Linux gains market share and as BSD sinks deeper into the mire of decay, their parting addresses will resound as fitting eulogies to BSD's demise.
What's this?! Only two "is dying" trolls so far. Pitiful! Stop being so lazy, and start posting, all you smelly GNU hippies!
"You see, even though I have never contributed code to any BSD project, I thought it was my duty to be a big asshole to others which don't use the OS I do, because it just 0wnz.", said one FreeBSD user. "Now that I know it sux0rs, though, I have to go find something else to be an asshole about."
One notorious OpenBSD fanatic known as WideOpen, told reporters, "I have to kill myself. This isn't how it was supposed to happen. My BSD has always been the best, and shouting that opinion in other people's faces at every chance I got has been my only hobby. It was all I ever did. It was what got me out of bed in the morning. Now I have to die. I will jam my bedpost up my ass until I hit my brain. It is the only way to go: BSD style."
In the volatile world of operating systems anything can happen. "At least we don't sux0r as much as Windows users", BigAzz, a relatively well-known NetBSD user said. "Screaming things in people's faces is my calling. Now I need to scream that BSD sux0rs. What a sad world. At least I won't kill myself like those uber-asshole OpenBSD guys. They are just way over the top. Or were, at least."
Nobody knows for sure what the future holds for the state of operating systems, but with Netcraft confirming the sux0r status, *BSD users all over the world will have to stick something else up their asses from now on or risk looking even more gay than they used to.
One more crippling bombshell hit the already beleaguered *BSD community when IDC confirmed that *BSD market share has dropped yet again, now down to less than a fraction of 1 percent of all servers. Coming on the heels of a recent Netcraft survey which plainly states that *BSD has lost more market share, this news serves to reinforce what we've known all along. *BSD is collapsing in complete disarray, as fittingly exemplified by failing dead last in the recent Sys Admin comprehensive networking test.
You don't need to be a Kreskin to predict *BSD's future. The hand writing is on the wall: *BSD faces a bleak future. In fact there won't be any future at all for *BSD because *BSD is dying. Things are looking very bad for *BSD. As many of us are already aware, *BSD continues to lose market share. Red ink flows like a river of blood.
FreeBSD is the most endangered of them all, having lost 93% of its core developers. The sudden and unpleasant departures of long time FreeBSD developers Jordan Hubbard and Mike Smith only serve to underscore the point more clearly. There can no longer be any doubt: FreeBSD is dying.
Let's keep to the facts and look at the numbers.
OpenBSD leader Theo states that there are 7000 users of OpenBSD. How many users of NetBSD are there? Let's see. The number of OpenBSD versus NetBSD posts on Usenet is roughly in ratio of 5 to 1. Therefore there are about 7000/5 = 1400 NetBSD users. BSD/OS posts on Usenet are about half of the volume of NetBSD posts. Therefore there are about 700 users of BSD/OS. A recent article put FreeBSD at about 80 percent of the *BSD market. Therefore there are (7000+1400+700)*4 = 36400 FreeBSD users. This is consistent with the number of FreeBSD Usenet posts.
Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.
All major surveys show that *BSD has steadily declined in market share. *BSD is very sick and its long term survival prospects are very dim. If *BSD is to survive at all it will be among OS dilettante dabblers. *BSD continues to decay. Nothing short of a miracle could save it at this point in time. For all practical purposes, *BSD is dead.
Fact: *BSD is dying
