  1. Re:Simple recipe on What Could You Do With a Bogus Root Name Server? · · Score: 1

    ISP access restrictions on their servers won't do anything for a client unknowingly connecting to a 3rd party via DNS hijacking/poisoning.

    Read (some of) the 25+ page discussion on Broadband Reports, linked in the article. Ports 25 and 110 were active and accepting connections, followed by rejecting all logins are (presumably) harvesting their credentials. My Nmap scans during the event are included in that thread.

    It was hardly harmless. They changed all the important host entries, including mail servers, and harvested logins of customers. I don't think many people would be happy if pop.gmail.com was redirected unbeknownst to user and their password was given away with a click (or auto refresh).

    The cheaper option rarely includes a box pulling 60W of power (even when idle or in standby) running 24/7/365, especially when it's time to decide on a new TV.

  7. Re:Even 100% is not good enough... on Verizon, Comcast Say They Are P2P Friendly · · Score: 3, Informative

    In practice, many (most?) ISPs use transparent HTTP caches, so having 50% of the data stay internal is still no good, as on popular files (eg, a big youtube video), 99% of the traffic stays internal for HTTP. No they don't. Start here.

    Confirmed today: Comcast, Verizon (DSL + FiOS), Time Warner, and Speakeasy.

    I don't blame Rockstar. I blame our union for not having the agreements in place to protect the creative people who drive the sales of these games.

    Have you considered negotiating for yourself? That's what I do when I get a job.

    Did you ever consider that maybe the reason people think they are happy with their lives is because they are and there actually isn't anything wrong with them? There's a whole lot of people on Slashdot who are happy to debate issues any day of the week that when it comes right down to it, don't really matter to a lot of people because they really aren't important. Time for a bigger world view, I think.

  20. Also noted in the FreeBSD 7.0 release announcement on FreeBSD 7.0 Bests Linux In SMP Performance · · Score: 2, Interesting

    Here, and it applies to a significant number of other network servers.

    Dramatic improvements in performance and SMP scalability shown by various database and other benchmarks, in some cases showing peak performance improvements as high as 350% over FreeBSD 6.X under normal loads and 1500% at high loads. When compared with the best performing Linux kernel (2.6.22 or 2.6.24) performance is 15% better.

    http://people.freebsd.org/~kris/scaling/bind-pt.png

    Summary:

    * FreeBSD 7.0-R with 4BSD scheduler has close to ideal scaling on this test.

    * The drop above 6 threads is due to limitations within BIND.

    * Linux 2.6.24 has about 35% lower performance than FreeBSD, which is significantly at variance with the ISC results. It also doesn't scale above 3 CPUs.

    * 7.0 with ULE has a bug on this workload (actually to do with workloads involving high interrupt rates). It is fixed in 8.0.

    * Changes in progress to improve UDP performance do not help much with this particular workload (only about 5%), but with more scalable applications we see 30-40% improvement. e.g. NSD (ports/dns/nsd) is a much faster and more scalable DNS server than BIND (because it is better optimized for the smaller set of features it supports).

  24. Stop misusing "Network Neutrality" on What Will Come of the FCC Comcast Hearing · · Score: 4, Insightful

    Network Neutrality refers to ISPs double dipping on charging/extorting fees for both users paying for their connections and web sites paying for prioritization of traffic according to origination and destination. It does not refer to protocol-based QoS. It does not mean a flat, unmanaged, unQoS-ed Internet. By repeatedly and deliberately misusing this phrase, its importance is being weakened.

  25. Holy rumor mill, Batman on Sony Paid Warner Bros. $400 Million to Go Blu-Ray? · · Score: 4, Insightful

    What remains a mystery is just how big a push Warner needed to pick sides. Analysts say Sony only prevailed following a heated bidding war against Toshiba, with the reward reaching as much as $400-million (U.S.). Neither side has confirmed the size of any bids or payments.

    Other than analysts' speculation of payoffs, there's nothing that could be considered fact in this article. Pass.
