Even if people have the knowledge, most people don't WANT to. Most people don't even make their own FOOD anymore, what makes you think they would ever want to build their own web sites, or orginize their own data? It's probably fair to say that most of the folks on this list either know, or could easily figure out, how to build and host their own web site. Indeed, objectives (1) and (2) can and have been achieved this way for many years. Building sites with one's desired features and linking them to/from other sites IS exactly what the WWW is all about. It doesn't extend to that scale. The macro view of the network does not apply to the micro. There are issues with applying it to the micro, in that your new 'microsite' is now fending for itself on equal footing with macrosites. Then, some cert advisory causes your little microsite to stab you in the back, revealing your data, and worst of all, be utilized to atack your friends microsites. There are construction laws which affect every single home in the united states. Unless you advocate the policing of individuals servers in a simular manner, then you cannot make the comparison between what you CAN do and what you SHOULD do. The average Joe, however, isn't a member of his local LUG. :) Most folks don't know how to, or don't care to, build their own Web site. This has caused people to flock to prefab pseudo-site services like Myspace, Facebook, etc. By that logic, again, people go to McDonalds NOT becouse they like it, or because it's convienient, but becouse they don't know HOW to cook. This mass migration to McWebsites completely disregards one of the fundamental features of the Web: the heterogeneous, distributed nature of the WWW. This, personally, has me quite concerned. Instead of hosting a Web site in order to host a Web site, people are putting pages on third-party services like Facebook. [Enter Mr. Homogeneity stage left.] Of course, there's also the standard set of security and reliability arguments for and against remote hosting of live data. And the propsed solution to the issue is.. *drumrool please!* To homogonize all of the data in such of a way that people can freely share their data publically with everyone else. In addition, most of these services are mutually incompatible. Note, incompatible isn't the word your looking for. The word is what you quoted above. 'Heterogenouse'. Placing my data on one site doesn't cause another not to work or function. They are all compatible on the internet. For example, Myspace and Meetup can't talk to each other. Add to that the possibiliy that your hosting service might lock down access (whether that means logging in to access a Facebook page or paying a recurring fee to host a Meetup group), and the online community has both serious practical and philosophical problems. What problems? Are you suddenly barred from using the internet? Or are you just annoyed that no one else wants to pay for you to freely use their service without you paying in any way, shape, or form? Note, paying isn't always cash. Sometimes, it's ad veiws, targetted spam, etc.. And don't make the comparison that information wants to be free. Sure, information wants to be free. However, even if your public library is offered to you for free doesn't exempt you from having to pay taxes to support it, and it CERTAINLY doesn't require that the library then also provide free parking. Now, here's the FOSS solution I was thinking about! Objectives (1) and (2) can both be achieved using existing FOSS. This problem's Achilles' heel is (3). If there was some kind of ready-made, drop-in, easy-to-use FOSS replacement for these services that could be plopped on any old hosting service, then the problem posed by (3) could be solved. People would be able to host their OWN sites, and wouldn't be forced to use mutually incompatible pseudo-hosting solutions like Facebook. Where's yours? Technically, this could be done a number of ways. Off the top of my head... (1) With a suite of PHP scripts that could be installed on any hosting service that supports PHP (not hard to find). Supported and maintained by who? (2) By installing a special package on a Linksys router. MMmmm.. New bot targets... Nummy..

Displaying only data matching a pattern?
I've been working with some large files and need to extract a piece of info, unfortunately there's a bunch of junk around the part that I want. Example: foofoo:A1234567890B\barbar foofoo:C9234567890E\barbar foofoo:A8234567890B\barbar foofoo:F7234567890D\barbar What I had done the first pass to get what I wanted was to use sed and do a s/foofoo:// to get rid of the stuff in front, and then do the same for the \barbar in the back. However what would be easier for me is if I could just extract the pattern of [a-fA-F0-9] when they appear n times in a row. I couldn't seem to figure out if sed could display only the part I wanted. So I figured it'd be a better job for grep, however It appears that it's printing the entire matching line and I only want the match on the pattern to display. Otherwise, I want as an end result: A1234567890B C9234567890E A8234567890B F7234567890D Here's a caveat: I need to do this on a Windows box and am limited to using the ports of GNU utilities (using http://unxutils.sourceforge.net/) otherwise I'd do this in perl and wouldn't be asking :/ I'm thinking maybe I'm just missing something simple here.

Re: Displaying only data matching a pattern?
Your man-fu might be a bit off too. ;) From the grep man page: -o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line. Also, if you have cut, it will probably run faster with: cut -d ':' -f 2 $file | cut -d '\' -f 1 or your output | cut -d ':' -f 2 | cut -d '\' -f 1 No regex generally means faster run times. Enjoy!

You could try it this way in gawk:
$ cat foo
foofoo:A1234567890B\barbar
foofoo:C9234567890E\barbar
foofoo:A8234567890B\barbar
foofoo:F7234567890D\barbar
$ gawk --posix '{ if (match($0,/[[:xdigit:]]{12}/)) print
substr($0,RSTART,RLENGTH) }' foo
A1234567890B
C9234567890E
A8234567890B
F7234567890D
You need --posix for [:xdigit:] and the curly braces ( {} ) to work. This
basically says:
if the line ($0) matches 12 hexdigits ([:xdigit:]) in a row:
print a substring of the line ($0) starting at RSTART and going for
RLENGTH characters
match() sets RSTART and RLENGTH for you on a match.

Tested here and this does what I'm looking for, and importantly works

Single-quotes (') have no significance to the Windows shell. So the
shell would still have done tokenization on the spaces within the awk
script, and awk expects its script to be a single C argument.
However, double-quotes are still used to constrain the text within to
a single token, similar to the Unix shells.
Unlike Unix, the Windows shell does not strip the quotes (IIRC). It
leaves them intact as part of the token. I would guess most Unix
ports introduce some kind of compatibility layer to handle argument
quoting.
The Windows shell is a crock, if you haven't figured that out yet. :)

On Mon, Feb 2, 2009 at 2:37 AM, Arc Riley arcri...@gmail.com wrote: That's hilarious! But jokes about PHP scripts and internet appliances aside, there *is* a real solution to this that's already accepted by the community at large. It's called XMPP - eXtensible Messaging and Presence Protocol. Thanks to Google and Livejournal there's already a huge userbase. It's inter-server, so all those @gmail.com users can use any federated XMPP service, and federation is easy. XMPP is a technology to assist in the distribution of data. It can be used to assist in the interchange of data however a grail it is not. Many services already offer XMPP access to their data, especially microblogging services like twitter and identi.ca. It doesn't matter what XMPP server you connect to (ie, gmail.com). If a feature isn't already supported by XMPP you can write an extension. Thanks to existing and well-deployed standards like pubsub (http://xmpp.org/extensions/xep-0060.html) many new services don't need to extend XMPP for their new functionality. What's at issue is that the meaning of data is still left as an interpretation to the student. Yes, you can shove arbitrary data and publish that data. That data still needs to be adopted as a standard by everyone. As an example, connect to google chat using PSI IM, and go ahead and try to get notifications when you have new emails. Facebook has flirted with XMPP in the past, they're currently planning to add support just for Facebook IM. There are already a number of XMPP gateway apps for Facebook hosted by 3rd parties. In Facebook's defense, they have an open API and allow anyone to host Facebook apps on their own servers that can access user's information and which have equal access to publish snippets to friend's pages. There are many libraries to work with Facebook's API. The crux of the complain is, however, that you have to authenticate with facebook. So a new model capable of obsoleting the existing paradigms, being as it must interoperate, is best implemented as XMPP service software. Nothing in XMPP forces anyone or anything to actually share data over the wire. And many would suggest it's actually a bad idea to open it all up to external, potentially untrustworthy, JIDs. In the world of federation, you have to trust the remote servers. With wide scale adoption of XMPP federated servers, you potentially run the same risks as MySpace, but with no central lockdown point any longer. Don't get me wrong. Sharing data via XMPP can be a great thing. But it is *NOT* the cure. The internet is primarily built around the idea of the routing of anyones data, in any way possible. XMPP is the SMTP of XML snippet routing. There is no concept of authentication of data in the world of the giant IPv4 network which has grown to be known as the internet. And that has allowed it to flurish. Minus some utopian identification service which can be trusted 100%, no technology will solve the issue. As part of that, the more XMPP is utilized, the more issues which crud up other protocol spaces will migrate there. Think I'm wrong? Example. Suure, you can disallow any traffic from anyone NOT on your contact list. However, how do they get there? They request to be there. Guess what's added to that? A message! Hrm..

Re: Conducting GNHLUG business on Facebook (was Stop! Unix Time)
DISCLAIMER: As usual, I speak only for myself. Some additional points not touched on already: (1) IIRC, all you need to register on Facebook is an email address and a name. You're not obligated to give them any more information than that. So if you'd like to register with Facebook for whatever reason, but you're worried about your privacy, simply don't enter anything more than the bare minimum. (1)(a) People who enter more than the bare minimum into Facebook do so (presumably) because they find value in it. If they consider targeted advertisements to be an acceptable trade-off, I don't think it's anyone else's right to tell them otherwise. (2) GNHLUG exists in at least two ways. (2)(a) One is the legal entity registered with the State of NH, which exists mainly for certain legal protections, and has little to do with what most people think of GNHLUG as. The only business that GNHLUG *ever* conducts is that voted on by the Board of Directors at the Bored Meetings. (2)(b) The other GNHLUG is the vague federation of people whose interests have an intersection with Linux/FOSS and NH. Members of this GNHLUG are members because they say they are. This GNHLUG exists because the members say it does. This GNHLUG has no legal status, but it's the one that really matters. Members of this GNHLUG can conduct business however they see fit, and other members can participate, or not, at their option. Free Software is about freedom. Free people don't always agree.

So, we had around 100 of these show up in the log from Sunday on liberty.gnhlug.org, all from the same IP address, all with similar but apparently never the same name pattern: client 192.0.2.42 query (cache) 'aaccmmfwxdlaaabaaafbbfpg/NS/IN' denied: 1 Time(s) client 192.0.2.42 query (cache) 'abbcnefwxdlaaabaaafbkkag/NS/IN' denied: 1 Time(s) client 192.0.2.42 query (cache) 'acdbbbfwxdlaaabaaafbpkeo/NS/IN' denied: 1 Time(s) (IP address changed to protect the guilty.) Speculation on what this is? An attempt to exploit the Kaminsky vulnerability? A DDoS attack that had a zombie directed at us by mistake? Some kind of bizarre dictionary attack? (For those wondering what this is: BIND is the reference DNS implementation. ISC is the organization which maintains it. named (name daemon) is the main DNS server program from BIND. These log messages are DNS queries sent to the GNHLUG DNS server, but which were rejected because we don't provide recursive service to non-local hosts.) -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: FOSS Gaming Survey - Any help is appreciated
The author of the survey seems to repeatedly mistake commercial for proprietary as well. I wasn't very impressed by the earlier questions either, the ones asking if you know RMS and Linus. Ok so perhaps some matchings on Moglen would be more appropriate..

Re: Suqashing Facebook (WAS: Conducting GNHLUG business on Facebook (was Stop! Unix Time))
On Mon, Feb 2, 2009 at 10:11 AM, Thomas Charron twaf...@gmail.com wrote: What's at issue is that the meaning of data is still left as an interpretation to the student. Yes, you can shove arbitrary data and publish that data. That data still needs to be adopted as a standard by everyone. As an example, connect to google chat using PSI IM, and go ahead and try to get notifications when you have new emails. IIRC, PSI does not fully implement XEP-0060, or even the personal eventing subset of pubsub defined in XEP-0163. Pidgin also has quite poor XMPP support. Of course this doesn't matter - if a client doesn't support a feature the service can detect that and fallback to a less elegant solution, such as sending you an XMPP message to remind you of an event you RSVP'ed for. The beauty in this is you don't even need a XMPP client running on your machine to access this data. If you have a client that understands the required extensions in a way that makes it useful to you, you can use your own client, or you can use a website that implements it - ie, just as you have a wiki account for gnhlug.org, you could have a thomaschar...@gnhlug.org JID used only for the website gateway. To you, a user of the website, XMPP support doesn't matter regardless if the XMPP is being run on the website backend or in your browser via a javascript client. Client support for extensions follow demand, so as such services come into mainstream the mainstream clients will support them. At that point you can use a single JID for everything. The crux of the complain is, however, that you have to authenticate with facebook. No you don't. There are many facebook apps that exist solely to provide facebook users access to offsite data (and vice versa). Take for example the roommate searching app. It's actually being run by a 3rd party website that's been running that service for awhile - all the facebook app does is provide access to that data via facebook. They could have taken it a lot further, such as when you post a looking for apt ad on their site, it could show Thomas Charron is looking for a new apt on RoommateSearchPlus!. Similarly, if you wanted to run a Meetup-type site targetting free software oriented groups, you would host the site on your own, expose an XMPP service to it (or even run the whole site's backend via XMPP - better than RPC!), and tie it into Facebook via their API so people who post events or RVSP to them have that status showing up on their Facebook pages as well. This doesn't force your entire member base to sign up for Facebook accounts in order to RVSP, just provides a way for Facebook users to help publicize the event to other Facebook users. Most of the libraries for Facebook API is free software. There is no reason not to write and implement Facebook apps on the basis of software freedom ethics. If you want to boycott Facebook based on them being a business that derives profit from advertising, that's your choice, but many of us find it's a useful tool. Nothing in XMPP forces anyone or anything to actually share data over the wire. And many would suggest it's actually a bad idea to open it all up to external, potentially untrustworthy, JIDs. In the world of federation, you have to trust the remote servers. With wide scale adoption of XMPP federated servers, you potentially run the same risks as MySpace, but with no central lockdown point any longer. Server federation isn't unauthenticated. There's a process requiring signed certs free, via xmpp.org, requiring verification of domain ownership only. Information, specifically presence and eventing, is provided on an permission-authorization basis. For example, your status (ie, offline, away, available, etc) is only given to other XMPP users you've authorized. This is how your roster is populated (aka buddy/friend list) and this same mechanism is used to manage who's authorized to send and will receive data from service nodes (ie, chat rooms, group calendars, etc). Think I'm wrong? Example. Suure, you can disallow any traffic from anyone NOT on your contact list. However, how do they get there? They request to be there. Guess what's added to that? A message! Hrm.. Sounds like Spam 2.0 to me! :-D Except given domain certs, unlike email spam, you cannot mask your source domain. If some dude in China federated his own server and started spamming everyone, poof, there goes his federation status. Email spam is typically sent from compromized windows computers running on IPs which don't have control of their reverse dns or ownership of their domain - both of which are required for the domain cert. It's going to be awhile until everyone has their own 64-bit IPv6 subnet and reverse DNS becomes easy again, at which point I'm certain additional precautions will be in place. Moreso, your argument reads akin to we shouldn't have a mailing list, because if it becomes popular, spammers will use it.
