  1. Patch antennas on Wireless Reflector for 802.11b? · · Score: 3, Informative

  2. SETI? on UWB Wireless Access Could Be Here Soon · · Score: 2

    I know this is not the most practical question, but I have been wondering for a while whether it would is possible to do a Search for ExtraTerristrial Intelligence (or a sky survey for whatever reason) for ultrawide band signals. I've heard that it is very difficult to detect UWB if you don't know exactly what you're looking for, but perhaps someone who knows a lot about ultrawideband could comment on its general detectability.

  3. Re:What else do you need? on ZDNet Discontinues AppWatch · · Score: 2

    What do you need in AppWatch that Freshmeat didn't provide?

    I would like a license filter or license ranking option and an automated update detector such as jdwhatsnew, ideally while still allowing user submitted updates.

    On freshmeat, the updates that you see are generally very current, but, to the best of my knowledge, you only see what people submit. For example, to pick on myself, I see that I have been remiss in submitting an update for the freshmeat entry for the July 17 release of version 1.6 of dvdtape. AppWatch's automated release monitoring provided more uniformity. As the amount of software scales up so that it's more work to double check for updates by visiting individual web sites, the value of this automation increases. Imagine if text search engines only updated from manual submissions.

    By the way, I read Freshmeat daily in addition to AppWatch, but I would usually start with appwatch for its update speed and focus on the type of software that I am most interested in. Then, I would typically visit freshmeat to see what appwatch did not cover and check out the unfree or GPL incompatible software (which I am also interested in monitoring after I've seen what's new in the GPL compatible space). I imagine that people with other copyright preferences might also like a copyright policy filter or prioritizer.

  4. Re:Two other ~$600 DVD recorders, Linux support on HP Introduces DVD Recorder · · Score: 2

    I'm pretty sure you're thinking any of the older Panasonic DVD-RAM drives (LF-D102U, LF-D101N?) that did not write DVD-R, which I believe identified themselves under SCSI as a magneto-optical drives.

    The statements that I have seen about needing the prorietary driver program only named the Pioneer DVR-A03 and a couple of drives that write "authoring" DVD-R's. So, it is possible that what you say is true about the new Panasonic drive. However, I don't know if it is physically possible to randomly write sectors of a DVD-R, and you certainly can't rewrite them. So, I would not bet that you could write DVD-R's with the drive using the standard SCSI magneto-optical interface, but you could be right.

  5. Two other ~$600 DVD recorders, Linux support on HP Introduces DVD Recorder · · Score: 4, Informative

    If you want a ~$600 DVD recorder, you already have a couple of other choices.

    At $629 on PriceWatch, the Pioneer DVR-A03 that a number of posters have already mentioned writes DVD-R at 2X, DVD-RW at 1X, as well as CD-R and CD-RW.

    At $535 on PriceWatch, the Panasonic LF-D311 writes DVD-R at 1X and DVD-RAM (1X for 2.6GB, 2X for 4.7GB), as well as reading the usual CD formats, but apparently not writing any CD format whatsoever.

    Currently, to the best of my knowledge, the only Linux software that can drive DVD writes is proprietary (sorry, there really is no good link for it). I am not sure whether complete information on how to drive these DVD writes is given in the SCSI-3 standards on www.t10.org or whether some additional information is needed. Any pointers to this information would be appreciated, as I might get ambitious one of these days and try to hack cdrecord or cdwrite to control these drives if nobody beats me to it.

  6. Steering Committee an improvement so far (IMHO) on RMS Accused Of Attempting Glibc Hostile Takeover · · Score: 5, Informative


    The basic idealogical dispute is that previously it was illegal to link glibc with proprietary software linked by non-GNU compilers due to a special "modified GPL" in the libio section of the GNU C Library. The change that the steering committee (who are developers like Roland McGrath, not just "Stallman") made was primiarily to convert that code to LGPL. Ulrich was the one being an idealogue about it. In this case, the steering committee was the group that was actually trying to get the right thing done for the users.



    The glibc-2.2.4 announcement advised everyone to switch to it. What the announcement did not mention is that if you try to configure glibc-2.2.4, you discover that it does not want to build under gcc-3. The steering committee is pushing for a fast release of glibc-2.2.5 which will not have this problem.



    So far, the steering committee seems to be a very positive influence. In the past, people were giving up hope on glibc due to its bloat, arcaneness, and legal issues. The SC seems much more focused on what users want.



    By the way, let me say that Ulrich Drepper has made many contributions to glibc and I hope he will continue to be involved as a contributor.

    The security standard in question is 802.1x, not 802.11x, because it is theoretically not specific to wireless, although the distribution of per-session WEP keys is. You could, for example, use 802.1x to authenticate conference attendees to use ethernet ports in conference rooms.

    According to Alex Belitis's Metricom-on-Linux web page, there was no hardware change. It's just that the Metricom pole top units were no longer programmed to forward peer-to-peer "star mode" packets for modems registered after December 23, 2000.

  10. DMCA is not mere legal harmonization on DMCA Worldwide: Canada, New Zealand, USA · · Score: 2

    Much as we may hate the idea, copyright is a part of the way the world currently works.

    All problems in the world are "part of the way the world currently works." That doesn't mean we shouldn't try to fix any of them.

    The existing laws were written before they had any idea of what computers would one day be capable of. Updating them to include [to the same degree of fairness] digital forms only makes sense. Otherwise you are left with unequal protection, depending on the media.

    First of all, DMCA does not simply extend copyright on software to the same degree that it previously existed for books. It has never before been illegal to make devices that could be used to circumvent copyrights on books, much less restricting devices that just allowed fair use. Remember, in the United States, at least, copyright is exists soley for the purpose of promoting science and the useful arts. Essentially, it is a question of economic policy. The government offers copyright and patent monopolies on the theory these monopololies will promote creation of these works more more than impede it. There is nothing immoral about different copyright restrictions being available for different types of works. It's just a question of optimization.

    Secondly, your use of the term "unequal protection" is completely misleading. In this cotext, "unequal protection" is not either morally or economically harmful. Disecting your words further, "protection" is a misleading term to apply to copyright restrictions, since copyright is not an inherently moral issue. What is restrictable by copyright is not exactly what is considered plagurism, and copyright is also unlike property in that violating a copyright does not deprive the author of his or her copy--the only deprivation is possibly of the royalties created by a copyright law in the first place. In addition, "unequal protection" in a legal context refers to people being discriminated against by the law. The government taxing cars differently from boats or having different types of safety standards for different types of vehicles is not the moral or legal wrong that that terms refers to where it is used elsewhere, even if you could argue the term could mean that in English.

    There are real problems with the Digital Millenium Copyright Act, both in terms of economics and freedom independent of any economic argument. It is not just a harmonization of existing law, and, even if it were, that would not be sufficient to justify it.

  11. Maybe this is already achievable on Linux Device Drivers, 2nd ed. Released Under GNU FDL · · Score: 2

    The Linux 2.4.7 Universal Serial Bus pegasus driver claims to support a bunch of Home Phone Networking Alliance devices. If the Linksys device is a version of these devices, you may be able to get support by just adding the appropriate vendor and product ID's to linux-2.4.7/drivers/usb/pegasus.h (and doing "cd /usr/src/linux && make modules && make modules_install && depmod && rmmod pegasus ; modprobe pegasus"). At the very least, reading pegasus.h will give you a list of USB HomePNA devices that should work with Linux.

    Otherwise, you might want to dump the USB device and interface descriptors (by activating some debug option in the core Linux USB driver or by the lsusb program) and see if your device exports an interface compatible with the USB Communications Class (wish I had a pointer to it in non-PDF form), which I believe includes an ethernet subclass. In that case, it still might be a lot of work and a lot of learning for someone not familiar with Linux device drivers and USB, but you would at least have some documentation (see http://www.usb.org for tons of free-as-in-beer USB documents).

    Apropos to community networks, I'd like to make a shameless plug for a GPL-compatible open source gateway and settlement system, downloadable from ftp://ftp.lanroamer.net/pub/lanroamer. The backend software will also be released under GPL later this weekend. There is obviously a business behind it, but the software and the ideas are relevant to this article in their own right. The basic idea is that whoever puts up an access point gets free use of the everyone else's access points and a significant share of share of the revenues from paying customers (expected cost to paying customers: $20-$25/month). We are in the process of setting up a sourceforge area for the software as well.

  16. Can we have a verbose mode? on Linus Says No To Annoying Boot Messages · · Score: 3

    Out the outset, let me say that I agree that kernel advertising/credits messages hide useful information and make the system unnecessarily confusing to less experienced users. I am glad to see Linus taking aim at them, as it really takes someone very respected in the development world to attack something that has so much ego attached to it.

    That said, I would like to still have a verbose mode that includes these messages so that someone who knows what they are doing can verify that a given facility is being initialized at boot. The simplest way to achive this would be to change DEFAULT_MESSAGE_LOGLEVEL in linux/kernel/printk.c, from 7 (KERN_DEBUG) to 6 (KERN_INFO), thereby filtering out KERN_INFO messages. Maintainers who feel that some of these messages really should be printed by default could submit patches to change them to the previously ill-defined KERN_NOTICE (5) level and try to convince Linus to apply them.

    It is also trivial for individual Linux distributions and sysadmins to modify this policy by booting with the "debug" argument (sets console_loglevel to 10) or to modify this in a boot script by writing to /proc/sys/kernel/printk as documented in linux/Documentation/sysctl/kernel.txt. A "loglevel=n" kernel boot argument would also be a helpful feature for the future and would be trivial to add.

  17. Zero on What Actually Makes Up "Linux"? · · Score: 1

    From section 2.2 of the paper (my emphasis):

    The ``physical source lines of code'' (physical SLOC) measure was used as the primary measure of SLOC in this paper. Less formally, a physical SLOC in this paper is a line with something other than comments and whitespace (tabs and spaces). More specifically, physical SLOC is defined as follows: ``a physical source line of code is a line ending in a newline or end-of-file marker, and which contains at least one non-whitespace non-comment character.'' Comment delimiters (characters other than newlines starting and ending a comment) were considered comment characters. Data lines only including whitespace (e.g., lines with only tabs and spaces in multiline strings) were not included.

    Since the copyright statements are comment, I infer that none of their lines have been counted. If you want to check this statement later, you're supposed to be able to download David Wheeler's sloccount code here, but the .tar.gz file seem to be accidentally read-protected at the moment.

    Come to think of it though, I would be even more interested in counts that included comments and documentation but somehow removed duplication, since comments and documentation also take an investment of time and add value (such as usability and maintainability) to the product.

    If you look a SuiteSisterMary's SlashDot user information page, you will see that almost all of this person's postings have been moderated up, even though they are typically trivial, not particularly insightful posting (and I mean this matter-of-factly, not as an intended insult). I had a discussion with SuiteSisterMary and noticed that each of his (her?) responses was moderated up to 2 as soon as it appeared, as was the case with all but one of SuiteSisterMary's other postings postings on that article. I believe that SuiteSisterMary may be maintaining a stable of slashdot accounts to use as they get moderator points (or perhaps arranging with friends to achieve the same result through their accounts).

    Although I do not think that it is possible to always stop this kind of abuse if the perpetrator is careful enough. On a case-by-case basis, one can point it out (as I am doing here, which is why I have attached this off-topic posting here). It might be a good idea for Slashdot staff to check if SuiteSisterMary has been sloppy about this by seeing if the IP addresses from which SuiteSisterMary's postings were made are the same the IP addresses from which they were moderated (or a group of very close ones, say, from a DHCP or modem pool) and if all of the moderation consistently happened within a minute or two of posting.

    It may also be possible to make some systemic fixes to at least reduce the problem, such as by preventing a moderator from moderating the same user's posting within one month (which would also discourage moderators from camping out on one particular thread for partisan purposes).

  22. Mutual compatability on Python Now GPL compatible · · Score: 2

    I would like to know why many people in the community are so hung up on the GPL. How is it better than the Apache, BSD, Mozilla, Artistic or other licences?

    The GPL makes certain types of free software businesses more viable by requiring that others who build on the GPL'ed work must make their work freely redistributable, but some other copying conditions also have this property to varying degrees, for example the Mozilla Public License. What makes the GPL special in comparison to other copying conditions that have this crucial type of restriction is that the GPL has the largest collection of legally cominglable software (which includes a lot of software that does not restrict proprietary variants, like "new BSD style", "MIT style" and public domain). This software includes critical components of a free system, such as the GNU compilers and the best implementations of a myriad of unix-style utilities. Why is the amount of mutually cominglable software important? Because the efficiencies of software sharing depend on what software there is to share, and often this sharing occurs in ways that were not efficient to anticipate as an prewritten programming interface when the software is originally created. Software recycling is a network effect. So, if you write code under GPL compatible copying conditions, it should find the most use, adaptation and contribution in the future.

    By the way, some people also feel there is an ethetical issue in wanting or opposing restrictions against derivative works. I think both of those groups probably feel something that is part of a larger efficiency ethic that angers us when we see our time being wasted even when we are being paid by the hour, for example, and that probably motivates a lot of free software development by itself.

    Of course, I imagine other people have other reasons as well. I certainly don't know everyone's mind on this.
