  1. Qmail, Netapp, F5 Labs, cyrus on Ask Slashdot: Building a Large Email Service · · Score: 1

    Here are some ideas that have been used to good effect at other sites, based on anecdotal evidence:

    Qmail - Fast mta, reliable NFS delivery in the Maildir format. Others may vote for PostFix. I don't know it, but it may do as well.

    Netapp - Fast nfs server. Multiple mail server can write to it. There are other NFS solutions from much higher-end storage vendors like MTI and EMC, but that may be more then you want :)

    F5 makes BigIP, a load-balancing ip switch. This lets you multiplex things like pop3, imap, and smtp to a farm of servers, and elimintas the possibility that anyone won't be able to check their mail or won't be able to receive email.

    Cyrus is an imap server. It's pretty good from all I hear. I still have yet to implement it. The other 3 parts I've used a lot, and love 'em.

  2. Set the record straight on Ask Slashdot: Building a Large Email Service · · Score: 1

    OK, here's the scoop:

    Hotmail runs many email servers behind an ip switch (ala F5's BigIP, Ipivot's Broker, Alteon's switch, Cisco's LocalDirector, LinuxDirector, etc). The responses gained from queso or nmap are the answers from the load balancing box, not the mail servers. This has been experimentaly proven and confirmed.

    According to all of their press releases they run sun hardware and solaris.

    Hotmail runs a (heavily) modified Zmailer for inbound connections, and local delivery, probably in some failsafe and distributed manner.

    Hotmail uses qmail for delivery, outbound. This version of qmail is also modified, at least somewhat, and probably a *lot* by now.

    Re: price

    Depends on whose pricing they're competing with. If they're shooting for EMC's market, and aren't going to undercut them, then I'd guess that the 420GB configuration will be something like $250,000.

    They will probably only sell the unit with support contracts that cost .2 * (cost of unit) for a year's worth of service.

  4. Storage system, not hard drive on 420 Gigabyte Hard Drives · · Score: 0

    This is IBM trying to get more money by selling hardware and services, and cutting into the market that EMC *owns*. These guys sell boxes that can be made more redundant then a chicken joke.

    In this market, 420 GB is pretty small, kind of like a bottom-of-the-line MTI system (no hardware control, just a box where you can hot-swap the drives).

    Puh-leeze. Anyone with any ethics would disclose any such statement, and reporter or publication worth reading would print such a disclosure.

    This is an extremely generous on the part of redhat. It seems that they're offering "friends and family" shares to any developer who wishes to participate, because they're acknolwedging that their company relies on our work. As with any company going public, these shares cost, but they're rarely offered to this large a group.

    As far as contributers to debian, and other distros are concerned, their work has gone into redhat's product, and redhat's work has informed and helped and been similarly incorperated with debian and the other distros as well. This may not happen so much these days, but it sure was the case in the past.

    Let's add: remove the offensively light treatment of slavery.

    No matter what era of slavery you talk about, slave life has never been this carefree. The many different (brief) reads of different slave cultures always include social stratification, restriction of privliges, lack of education, lack of right to any posessions, lack of personal space, lack of extra food, lack of clean living space, etc... general second-class citizen status, without the citizenship. How does it come about that a slave has a good education, friends who can freely come and go in the daytime (the time when most work gets done in most cultures), enough parts to put together a droid and a racing doo-hickey, food to share etc...

    Those who have _abnormal concentrations_ are trained as Jedi in the old days (and suffer from the exclusivity and secretiveness common to cloistered groups.)

    I like your optimism about the possibility of growing egalitarianism, and I think that nothing I say necessarily disgrees with it. However I think you're ignoring the plot point that the little unspellable beasties that allow for the use of the force possible impregnated a woman to create Anakin. This would indicate to me that the existance in the star wars world of abnormal concentrations of these beasties shouldn't be confused with arbitrary distributions of people with abnormal concentrations. The people would seem to be "chosen" by somewhat cogniscent sentient biengs.

    Though the cause isn't genetic it seems more then likely that it is supposed to be pre-determined.

    I think a lot of your other points are respectable, but I don't think there's enough depth to the movie to offer a good discussion of them. Using Obi-wan's anger as an example...

    Lucas clouds the issues that you bring up by offering an oversimplification of human emotion. Is Obi-wan feeling anger? Is it grief-driven rage? Is it desperation that leads to darth maul's slaying? It could be any one of those, but it's probably anger because that's about the only emotion that Lucas is ready to deal with in his movies. He makes his world so black-and-white that every character is limited in their options. I wish there was more here to base discussion of this particular point on, but it just doesn't seem to be there.

  11. Re:Brin - hypocritical totaltarian! on David Brin on Star Wars: TPM · · Score: 1

    He then complains that Lucas doesn't base any of the concepts in his movies on his pride and joy -- democracy. If I recall correctly, the queen distinctly said "I was not ELECTED" -- that suggests democracy to me.

    The word "suggestion" here is important. Lucas uses a lot of mixed symbols from different traditions to affect the atmosphere in his movies. The title of "queen" is probably used to be evocative for the movie because that makes her a special character, and likely because she is not a democraticly elected political figure. The "election" mentioned doesn't necessarily mean a fully democratic election, or even a remotely popular election. Reading "Hamlet" you'll be reminded that in Denmark the king was chosen (aka elected) by a body of rulers. In ancient rome I believe the ruler was "elected" by a rather select few. Besides, can you imagine, really, voting for a 16 year old kid? Hello? Besides, where would an otherwise normal looking teenager get a wardrobe that included a black wire-frame dress that has slowly blinking LED's framing her face if she wasn't... say... born with a royal inheritance?

    History has a lot of examples of "elected" rulers whose rule had nothing to do with the choice of the people they ruled. Start with communist countries, i.e. the "Peoples republic of china" and tell me if you think that the ruler was asked by the people to kill and torture them.

    Lucas also depicts the reality of democracy not the fairy tale Brin wants it to be. So what! His illogicities about the senate and the naboo are completely unfounded -- UN!. Most of his illogicities are unfounded.

    Lucas is manipulating a powerful symbol, and a modern one. The cooperative ruling body. He obviously doesn't believe in it. The extent of his distrust is the bummer, and the fact that he expresses and supports that distrust to, us his audience, could be seen as a disservice since it's an entirely uninformed opinion that we're supposed to buy along with the story to make it real

    .net,.com, and .org domain "speculators" are real problem. My understanding is that they do not pay for the vast majority of their thousands and thousands of domain names.

    So, if fighting against squatting is going to be moved to the next level, something has to be done. Most companies that squat on domain names never bother paying the dues because NSI doesn't require immideate billing for companies that already have a great number of outstanding unpaid domain names. If that were fixed then the profitability in domain squatting would be blown away.

    In addition, NSI completely overcharges for the maintanence of their database and nameservers. By now it's widely known that they are completely mis-managed, and many people would like to demonstrate how easy it would be to design a better system from the ground up, at a low cost.
