  1. It's not really a problem for me. on (Almost) All You Need To Know About IPv6 · · Score: 1

    IDG is an interesting workaround, but I don't really need it. Until 6 gets here, OpenSSH does what I want. I can get files and gui's out of my network. That's all I really need until I bother with VOIP, but then I can do that on my gateway machine as easy as I can on any other.

    The thing I thought was funny was how they carefully but incompletely stepped through the hypothetical argument they had just made fun of. What it showed me was that both Windoze and Mac have serious and arbitrary limitations that create ignorance and force poor networking practices on the world. If you don't understand and work within those crazy limitations, you just are not leet like the Ars people are.

M$ pushed WMA as hard as they could, making it the default format for WMP, shoving it down the throats of device makers while forbiding them to use ogg, but WMA still flopped. It flopped because it sucked. They said it was better but it was not and everyone ignored them.

  3. NAT Translation is Dead On. on (Almost) All You Need To Know About IPv6 · · Score: 4, Insightful

    The article does a great job of presenting the debate. In every talk, you should tell the audience what you are going to tell them, then tell them, then tell you what you told them. In this case, the author took the novel and interesting approach of using a Slashdot summary of the subject, linking to a previous discussion and paraphrasing it. I present the summary and the expansion side by side to highlight their ingenious rhetorical style:

    "Use NAT, n00b. All 1337 of my Linux boxes share a single IP and it's safer, too!"

    Hosts behind a NAT device get addresses in the 10.0.0.0, 172.16.0.0, or 192.168.0.0 address blocks that have been set aside for private use in RFC 1918. The NAT device replaces the private address in packets sent by the hosts in the internal network with its own address, and the reverse for incoming packets. This way, multiple computers can share a single public address.

    "NAT is not a firewall."

    With IPv4, there will generally be a NAT device that functions as a simple firewall by blocking incoming sessions (although there are ways to trick NATs into allowing them). If you're working on security, keep your eye out for IPv6 because if overlooked, IPv6 could allow things that are blocked over IPv4.

    "NAT sucks."

    [1]However, NAT has several downsides. First of all, incoming connections don't work anymore, because when a session request comes in from the outside, the NAT device doesn't know which internal host this request should go to.

    [2]Things get even trickier for applications that need referrals. NAT also breaks protocols that embed IP addresses. For instance, with VoIP, the client computer says to the server, "Please send incoming calls to this address." Obviously this doesn't work if the address in question is a private address. For this reason and a few others, most of the people who participate in the Internet Engineering Task Force (IETF) don't care much for NAT.

    "You suck."

    This [1]is largely solvable with port mappings and protocols like uPnP and NAT-PMP.

    Working around this [2] requires a significant amount of special case logic in the NAT device, the communication protocol, and/or the application.

    More to the point, NAT is already in wide use, and apparently we still need 170 million new IP addresses every year.

    Thanks for the shoutout, Ars. The explanation of various non free software limitations for using IP4/IP6 and partial explanation of why those systems may need firewalls to begin with is sure to add to the human body of knowledge and foster civilized conversations. After reading the article, it's all clear to me, for sure not at all. Respeckt!

  4. Bill Gates never cared about your job. on Bill Gates Speaks Out Against Immigration Policies · · Score: 1

    Far from displacing US workers, highly skilled foreign-born workers will continue to function as they always have: as job creators.

    Do you really think Mr. Gates wants new software companies that compete with Microsoft? The same Bill Gates that's trying to kill Google and Wikipedia like he wiped out Netscape, Palm, OS/2, Correl, Caldera and so on and so forth? How can you believe what he has said, knowing his company's predatory past?

    No, Mr. Gates is not interested in US job creation, he's interested in lower operating costs for M$. If he wanted to create jobs he's got all the money and position he needs. Instead his shadow hangs over every tech start up and has discouraged everyone, much to the detriment of his business model. His business model has always been to buy the "loss leader", or their employees, for substantially less than it would cost him to make his own product and then use it to crush all other competitors. Far from creating new jobs, his approach has destroyed existing jobs and discouraged tech investment which would create future work. Now, as people with any sense are avoiding tech like the outsource prone disaster it is, Mr. Gates finds himself unable to "innovate" cheaply.

    The non free way no longer makes money for anyone who's not a M$ vassal, and increasingly, those are feeling the squeeze too. Fortunately, free software continues to provide users what they need and profits for those who would compete fairly. IBM, Google, and just about everyone but M$ is sick of M$.

  5. Non Free Blessing? on Tricked-Out Cars Trickling Down · · Score: 2, Interesting

    I worry about upgrades.

    Upgrades are just one practical and obvious problem with non free software in cars. Your worries are justified in an industry that practically invented "planned obsolescence" and still practices every form imaginable. Just look at the myriad of mechanical and electrical fasteners that already exist in automobiles when standardization would be cheaper. Of course they chose M$, when they could have better control and lower costs of their own gnu/linux based systems.

    There are more sinister problems with the lack of control non free software enforces. Some that spring to mind are

    • OnStar type bugging of cell phones through the bluetooth system that can be done outside of public network protections,
    • inaccurate and impossible to audit reporting of driving habits to insurance comp,
    • private geographical tracking,
    • computer failures making the car unusably inconvenient if not dangerous,
    • single source subscription radio,

    Other people can think of more sinister things, because I'm basically honest and don't think like the above.

    The civil liberty implications are the most disturbing, even though they directly effect a small minority of activists who may be harassed and silenced. The indirect effect of a corporate/government police surveillance state apply to all and are much greater than the sum of their parts and is miserable for everyone. The only thing more expensive than liberty is slavery.

    I'm going to avoid the whole mess, if I can. I have devices that work and don't need built in toys.

    "And use of IPSec would foil some higher-level protocol attacks, and digital signing of IP address assignment records could reduce some routing/spoofing risks," he says. OSes need to be more airtight, too, and two-factor authentication should be more the norm than plain old passwords, he says.

    But Cerf knows securing his baby won't be easy. "Security is a mesh of actions and features and mechanisms," he says. "No one thing makes you secure."

    It's too bad the reporter injected so much of their own opinion into the article. I'd much rather have heard Cert's own words than interpretations. The result is that it looks like the reporter did not ask the right questions at the time to get clear answers.

    Reading and rereading the above, it looks like he's thinking of ways to make the network work without having to trust the clients attached. That would be a neat trick.

If companies really care about that, Apple is the winner. In every other category, free software wins. Right now, free software offers control, hardware costs, flexibility, stability and applications people in the non free software world envy. User created tools do the user's work better than boxed bits.

    Don't cry about legacy systems holding them back either. Those are non free problems that go away as soon as you get out of the non free world. The longer companies wait, the more they pay and the harder it gets. Every dollar you spend on non free software is another dollar the non free software companies use to build the next trap for your data. Now, as M$ transitions to Vista, is the best time to jump. Wine, crossover office, email exporters and all sorts of other tools work with current M$ junk. Vista will, I'm sure, break many of those tools and make things harder again. Rather than spend lots of money on a Vista downgrade, people should be making a free software upgrade. Apple and M$ have their legacy niches, and that's where they should be deployed until those gaps are filled. Many of those gaps can be filled with virtual computing. Actual needs, like small scale movie making and drafting, would give non free a vanishing minority OS share.

That they can't is one of the biggest downers of non free software. The game only works as long as everyone co operates to screw the customer and each other.
