  3. Re:LBX sucks on Proxy Servers Lighten Up X · · Score: 1

    Keith seems to believe that the solution to X performance issues lies in the clients; and in the long run this may very well be true. However, NX takes the old proxy/agent paradigm pioneered by LBX and dxpc and does something useful with it finally.

    Actually, that is not strictly true. It took some effort, but I compiled up NX from scratch (It is available under GPL). One of the things it does is provide an xlib replacement which you sneak under the program you want to run using LD_PRELOAD. That replacement makes a huge difference. So, in a way, they are doing a runtime replacement of all the bits in the client that talk to the server.

    I think this is one of the major reasons why NX works so well compared to LBX and friends. The other is that it keeps a fully persistant (between sessions) cache of bitmaps on the client side. It really is beautifully done.

    The guys working on Xouvert have talked about working it directly into their version of X, and this would make me a very happy camper indeed.

    Hm. I dunno. The only "cover up" in progress has been the reluctance of developers to speak out and call a spade a spade. The fact is that the new nVidia hardware simply can not compete with the new ATi hardware. Period. Go scratch around on the net and look at the technical details.

    I was really happy that Valve had the guts to speak up. The only company consistently at fault in this whole fiasco is nVidia. Their latest ploy is to release a driver that uses reduced precision shaders, and pretend that its as good as the Radeon default settings. This is obvious in the first few days after the release of the det50 drivers. I'll wait a few weeks to be vindicated though.

    Just in case you wonder, I am an nVidia card owner. This will change though. I am thoroughly disgusted with their behaviour to date. They lost and they would rather lie and cheat and bluster continuously than keep my trust. Sure, they might not sell as many cards in the short term if they just admit they screwed up and we'll have to wait for the next generation of their cards, but they sure as hell will lose out in the long term. They could admit defeat and bring their prices down and bite the bullet. Their current generation would make great low price video cards if you didn't care too much about image quality.

    Not really, because I realise that you can often do better than the entropy coding in the compression format. It has to be fast, and it might be compressing the stream without examining the whole stream beforehand. Hence you can often gain a few percent with zip or whatever.

    I am currently working on my own codec, which, at the moment, doesn't use any entropy coding at all. Its better than MPEG-2, but not quite as good as MPEG-4 yet, but I have a long list of things still to do. I may not add entropy coding... it just might not gain me enough size to be worth it given the speed penalty.

  11. Re:That's a good point on The Next Step in Fighting Spam: Greylisting · · Score: 1

    So who's going to vet it as 'spam?' Want to do it after the DATA message is sent? Then you're doubling your bandwidth.

    Want to try to identify based on the fact that there's a ton of mails coming through in a short period of time? What if the spammer simply re-orders his spam database, so it's not sorted by domain? If he has 1,000,000 emails, with, oh, 10,000 separate domains, then only every 100th email he sends will be to your domain, if he spaces them properly.


    *nod* It is true your suggestion doesn't work. However, there are other possibilities. I used the word "distributed" for a reason. Here is one example:

    Several people band together in a loose way. These people set up SMTP servers for domains that don't receive any real email. The server can be configured however you like. However, it never delivers mail. It simply records the IP of whoever connects to it. End of story. No tuples, spam characterisation, to or from addresses, nothing. You advertise some addresses for this domain by sticking them on web pages or whatever. By definition all connections to those servers are from spammers.

    A spammer connects to your real SMTP server. It gets told to go away cos its new and untrusted. Now, the only way it can get a message to someone on your server is by reconnecting an hour later from the same IP and retrying.

    In the meantime, the spammer has attempted to send this message to other addresses. He hits one of the honeypot SMTP servers in your distributed network (and, the bigger his mailshot, the more likely this is). Every 30 minutes you collect the list of IPs that hit the honeypots, and dump them into your blacklist.

    An hour later your spammer tries again, but you now have that IP in your blacklist, and either silently drop the message, or just keep giving temporary errors.

    If you make your honeypots behave identically to real servers, and give temporary errors too, then any retries by the spammer to honeypots will just revalidate that the spammer is still using that IP.

    You make your IP blacklists slowly time out old IPs, so that if the IP is re-used by a legitimate sender he is not indefinitly locked out. This is unlikely to cause problems anyway, cos most people use their local SMTP server provided by the ISP to send email, and it knows the address ranges it serves.

    I'm not attacking anything. I'm simply pointing out design issues (not necessarily flaws!) that the author, or you, might not have thought of. Isn't that one of the ideas behind open source? A sort of darwinian wheedling?

    Excuse me for sounding off before, but from my reading of the article, it seemed quite clear to me that he had thought of this. You happened to the straw that broke the camel's back. I had just read a bunch of posts by people that carefully combine ignorance with a desire to read half the article.

    Please excuse my outburst. However, to back up my point, here is a quote from the article:

    # It is long enough to provide a good chance that if the sending host is in fact a spammer, they will be listed in other IP-based blacklists that may be used in conjunction with Greylisting, so that even if a spamming relay later attempts a redelivery that would no longer be delayed by Greylisting, it may still be blocked by other methods.
    # It is also long enough that other types of traffic analysis could be designed and implemented such that spamming IP's could be easily identified and blocked by other methods, in such a way that even the first recipients (before a spamming pattern starts to emerge) would still not be bothered by the spam email.

    :-/ No. I think you aren't getting this. The whole point is that a new sender is untrusted for one hour. You now have one whole hour for other spam control measures to blacklist that IP, something that should be pretty simple with any kind of distributed database of SMTP connection attempts to honeypots, etc.

    It's called greylisting for a reason. Stop thinking in black and white. Its an extra layer that is used to give you a tactical advantage. It makes your life easier when fighting spam. It's not The Final Solution, which is clearly acknowledged by its author. It's a tool. It's one more layer in the fight against spam.

    So what if spammers write their code to try again in an hour? The RFC complaince thing is a red herring for you. It's the logical next step for spammers to make their code compliant. And when this happens, you have a method of giving you an one hour period for a distributed immune system to respond.

That was almost as much fun as doing the boot sector stuff.
