  1. Don't scoff at 16 million loopback addresses. on MIT Technology Review Slams IPv6 · · Score: 1

    There's lots of interesting things you can do with a scheme like that. For example, NTP uses the various loopback addresses to implement fake peer clocks. The particular quads specify "drivers" and parameters to use to talk to the time source.
    What's nice is that it's portable top any system with a sane sockets layer.

    It's the kind of thing where you look up some service in a database, which gives you a number. You translate that into an IP address, then try binding to it to see if that service is available. Forget TCP, you can just use raw IP datagrams since there's no way delivery can fail. It's more familiar territory than IPC for some people (and more portable).

    Well, maybe 16 million is excessive. We only have 64k TCP port numbers, and that hasn't been too problematic.

  2. And 174 and 192... on MIT Technology Review Slams IPv6 · · Score: 1

    224-255 are for multicast.

    I'm confused as to why we just don't have 1 or 2 multicast class A's, because AFAIK, no one uses it! At least my ISP doesn't really support it.

  3. Are you dense? on Engineer Deconstructs Literary Criticism · · Score: 1

    The point of the original rhetorical question is that you can't interrogate the person (or group) directly because it is infeasible or impossible. All you have to go on is distorted versions of history from every interested party. I am suggesting in the second paragraph yhsyyou need a specific set of mental tools (the Humanities) with which you pick such situations apart for the purpose of making future predictions, or just the satisfaction of knowing "how we got here".

    That fact that you disagree this what the Humanities are good for is further evidence that academia has distorted it's original purpose.

    The undergraduates are not perpetuating this, they are only being indoctrinated. I did not mean to group undergraduates with academia in the final paragraph. They are NOT being shown how they can apply it to the real world by the same people who should be doing so; their professors and understudies lead by example, having cut themselves off from the rest of society.

    I think you're being semantic so you can avoid addressing _why_ you feel you disagree with my position on the Humanities purpose. You haven't shown me how they are not supposed to provide you with the means to analyze social situations, regardless of the current dismal state of the art.

  4. Errm... what? on Feds Thwart Extortion Plot Against Best Buy · · Score: 1

    Sure a hardware scanner could detect something with 0 latency, but that something would need a comparator as wide as the entire string to match, multiply that by the number of possible shifts in the analytic unit you are considering.

    Moreover, you would need multiple units to match multiple strings. So if you had a list of 256 "bad" strings, you would need fan-out of 256 on the signal. Or have a system clocked a certain factor faster the same amount of internal parallelism, In any case this is non-trivial in dedicated hardware, even with fancy shit like FPGAs and 90 nm processes.

    This would be a big expensive machine they would have to install at every ISP. No, I don't think the FBI could pull off putting together something that specialized. The NSA? Quite possibly. But it would be hard to get ISPs to buy into it.

    And what the hell does that have to do with AM radio? The RF your computer emits is primarily in the form of the magnetic fields induced by fans and drive head motion (provided you turn off your monitor... you know, Tempest)... good luck getting anything damning out of that.

    You need to loosen your tin foil hat, it's on a little tight and has distorted your grasp of information theory and physics.

  5. It boils down to this: on Engineer Deconstructs Literary Criticism · · Score: 1

    Have you ever wondered how in someone's right mind they could write something, argue some point, make some speech, appear in a terrible movie, etc. - while lacking the ability to ask them and/or get a direct answer?

    Well the Humanities are (in theory) supposed to give you the insight into reading behind the lines, and figure out what motivates people (or society) to do the things they do. Usually they equip you to do this by analyzing and studying older cultural artifacts (history, art, literature) in the hope that it brings perspective.

    It seems that academia has given up on trying to make this stuff relevant anymore, except maybe to social scientists and anthropologists.

    1) They include all hardware under the sun.
    2) They assume you've applied about 50 patches to the stock kernel (some of them RedHat specific), so a lot of the stuff is going to be ignored, or could cause the make to fail.

  12. Screw that. LCoS is the true path. on CES 2004 Coverage · · Score: 1

    LCoS is offering the highest resolutions and even more impressive color contrast (with the exception of direct, not projection, LCD). They cost about 25% more than a DLP set of the same resolutions.

    The units are not wall-hang thin, but they are light and space saving, despite being projection units.

    Maintenance and care is similar to that of a DLP box.

    He had a really good point, but intentionally buried it with that same sort of cleverness the academics he critizes might use. At least he didn't resort to using meaningless jargon...

    I think the fact that we're discussing these points right now (on Slashdot!) is probably a good thing, perhaps not intentional when he first wrote it, but after later reflection, allowed to stand as is.

  15. You do realize... on Performance Benchmarks of Nine Languages · · Score: 1

    That runtimes less than one second long, and programs that are small enough to sit in cache are probably not good indicators of true compiler performance. Even if you ran those tests 100 times, you are too close to the timer interrupt resolution to get any meaningful results.

    Try filtering up to 100M, at least (I can't think of any way to use the cache less efficiently that isn't trite).

  16. Mmmm... on World's Fastest Internet Transfer Rate? · · Score: 1

    You can't overcome latency. There's a fundamental limit. I mean, satellite communication links have latencies of 1 second because of the speed of light, and you can't "improve" that by much. The latency is a side effect of the distance. Which means that you actually trade-off effective bandwidth when you increase distance because sustaining throughput with error correction gets harder.

    So a doubling of distance should get you bonus points! You can overcome system latency with fancy hardware, but you can't fundamentally improve distance effects. So as a pure measure of system performance, I think distance is key to knowing the true prowess of said link.

  17. Make it worth their while to want to enlighten us. on Engineer Deconstructs Literary Criticism · · Score: 1

    Somehow you have to create a market for people to want to know the how and why behind the stories, cultural themes, whatever that people deal with/relate to day to day.

    And I'm not talking about Reader's Digest. Example: It might take a tabloid publisher or something similar to find the right kind of spin and attitude to hook people into reading these uniquely informed opinions on modern cultural trends... condensed and simplified, of course.

  18. In case you missed this... on Engineer Deconstructs Literary Criticism · · Score: 4, Insightful

    The article really isn't about deconstructing the humanities at all. That was the method the author used to expose the deeper problem: that the humanities are suffering because their most artful practicitioners have isolated themselves and no longer respond to the community.

    One thing he didn't really emphasize, but only alluded to (in a paragraph where he admits how this thinking caused him to understand why it might be important to conisder the fraility of many kinds of writing) is that these humanitarian skills are really useful! Only undergrads aren't really shown what they could do with them in the real world, besides branching off into various fields of media criticism.

    He should have driven his conclusion home harder... that academia needs a slap upside the head, and we ("Nerds") all could help a little.

  20. That's awesome. on How Much Broadband Usage is Too Much? · · Score: 1

    I had a anonymous-uploads feature turned on, and I noticed that some shady people started using it.
    But all I got were some weirdly named files (probably SHA1 hashes) a megabyte in size. They were using my FTP as a public drop box for their own freenet-like software.

    The files didn't look like they had internal checksums, so I just put an equivalent amount of data from /dev/urandom into them.

    Next time maybe they'll play nice.

  21. What the hell are you downloading? on How Much Broadband Usage is Too Much? · · Score: 1

    At 1.5 mbps so frequently and yet aren't contributing back at even 256kbps? That's a real extreme imbalance. If anything, I always bitch about my upload and I wish they would shift the bandwidth allocation in it's favor a little.

    Hell, make it dynamic! A SNMP settable string on the cable modem or something. Because shoddy upstream means I can't host a game server or web/ftp serve or anything effectively.

    Plus it ruins bittorrent.

  22. Joining samba 2.2.x to an Active Directory DC on What is the Worst Tech Mistake You Ever Made? · · Score: 1

    Just because you can do something doesn't mean it's a good idea.

    No one could access the shares on that particular fileserver anymore ("Can not log in from this workstation"). Thing is that the same error message is used when there's an encryption policy mismatch between client, samba share, and/or DC, which I spent 6 hours trying to track down.

    And I thought I would be saving time with the switch to domain instead of server/share security.
