Wow they didn't use any DB at the start of UO, that is amazing haha
"As Raph also notes, there were no databases originally involved in the storage of game state or player data for UO (disregarding analytics here), everything was kept in flat files. Backups worked by flagging a moment in time where no one was allowed to cross server-boundaries -- during that moment, each areaserver was commanded to fork(), essentially duplicating itself in memory (it's more complicated than this, thanks to Copy-on-Write, but let's simplify). After everyone had fork()ed, the "lock" preventing boundary-crossing was cleared. Then each areaserv began to dump out its huge chunk of memory-state into a file on an NFS server. Those files were then all tarred together and kept as a "backup" of the state of the server. These heavyweight backups happened at half-hour intervals, I believe."
EDIT: Check your local law first. I've just noticed during research using facebook that i don't get the paywall coming from there. This is only a proof of concept, if you want to read WSJ, than you should consider paying for a subscription.
Sensible doctors do not believe drug company marketing.
I get large amounts of ad-junk from drug companies that ends up unread in the bin. I refuse to meet with drug company representatives. I smile politely at them if I bump into them in the corridor and suggest that they leave their ad-junk with my secretary. My staff then file their ad-junk in the trash bin.
On Friday, I had a drug company representative attempt to tell me ( he was hanging around my coffee area ) about the joys of Targin, a fixed-dose combination of oxycodone and naloxone. I gently shook him off, and directed him to my secretary.
Drug company representatives are usually decent human beings with lives and families. However they are poorly educated, poorly informed salesmen and women with sales targets to meet and product managers to keep happy. Even worse, they and the drug company have no accountability if a patient dies because of their recommendations. If avoidable death supervenes or if there are non-lethal complications or even just therapeutic failure, I am accountable.
Instead of relying on marketing, I rely on information from good, well performed randomised controlled studies published in reputable peer reviewed journals ( I like the NEJM ) and on meta-analyses of these. I view the results of these through a filter of scepticism, cynicism, pragmatism and a modicum of hope.
Many of my colleagues do likewise. I trust that you do the same in your respective vocations. Regrettably, there is a bell curve. I am sure that the drug companies find enough gullible prescribers out in the wild for their purposes.
