Interactive map of Linux kernel source
Constantine Shulyupin [const at linuxdriver.co.il]
Thu, 11 Sep 2008 21:00:37 +0300
The Linux kernel is one of most complex open source project. There is a lot of books, however it is still a difficult subject to comprehend. The Interactive map of Linux kernel (https://www.makelinux.net/kernel_map) gives you top-down view to the kernel. You could see most important layers, functionalities, modules, functions and calls. You can zoom in and drag around to see details. Each item on the map is hypertext link to source code or documentation.

Thread was about software options for "syncing" smartphones with calendar/mail servers (more or less).

> According to Slashdot, Zarafa has just been open sourced.
Rules of thumb:
1. Be skeptical of any claim that a Web 2.0 application is open source until you've carefully examined the actual licence. There's been an extremely large amount of cheating, deception, and outright lying about licensing in this market.
2. Be doubly, super-skeptical of those claims when you go through the project's Web front page and find three claims of open sourcing but nothing whatsosever about the licence.
In this case, a great deal of digging, one finally, on a subpage, finds a Sept. 18 press release saying that the "full core" of the Zarafa platform will be at some unspecified time be available under Affero GPLv3. Affero GPLv3 is indeed a genuinely open source licence targeted at the Web 2.0 / SaaS / hosted-software / ASP market -- even though it isn't yet OSI-certified.
The real remaining question, then, is whether the "full core" -- whatever that means -- will be turn out to be a viable, useful piece of software. Another scam that's extremely common in Web 2.0 space is to have a deliberately buggy, undocumented, incomplete "community" version under open source licensing, functioning strictly as a sales come-on to upsell users to a "commercial" (proprietary) version.
I'm trying to remember the leading example. Hmm, Sug[censored for reasons of legal self-defence]

an address book/ diary programme ...
Jim Jackson [jj at franjam.org.uk]
Sat, 6 Sep 2008 01:12:19 +0100 (BST)
Hi, all
A friend is looking for recommendations for cross platform software, ideally linux, MacOS-X, Microsoft - "an address book/ diary programme that can be synchronised with other computers. Ideally this would work like the old Psion one, where it can be synchronised automatically with Lotus Organizer or Microsoft Outlook on an office computer."
Any sage advice?
Jim

License Question
Martin [martin at marcher.name]
Sun, 21 Sep 2008 01:45:08 +0200
Hello,
according to your author FAQ[0] under "Copyright Issues" you state that you will publish the works sent to you under the Open Publication License. The Wikipedia article states that the author of the OPL recommends using a Createive Commons License as a replacement. I understand that there are issues with the existing articles which may prevent relicencing them but for new articles would it be OK if I'd like to articles to be published under a Creative Commons License - personally I prefer "by-nc-sa" for written works and "by-sa" for code works.
Given that efforts to keep the OPL updated seem to have stopped (actually never made it beyond a version 1.0) at 1999-07-08 I think switching to a CC license should be considered, maybe even let authors choose between
* default (stay with OPL) * the CC options
any thoughts on that?
regards martin
PS: no I don't think you can't google but I guess it's a lot easier to just click the link of my sources, we all got enough work to do.

Using DNS blacklists to reject mail.
Joey Prestia [joey at linuxamd.com]
Fri, 19 Sep 2008 19:09:22 -0700
Hi all,
I am wanting to gather some information about using DNSBL on mail servers. I have been reading the information on most of the more popular used blacklists like Spamcop and Spamhaus. Now I have come up with all kinds of questions on the subject.
I would like to hear from any mail server administrators of their experiences with these methods of rejecting spam at the "gate". It seems apparent that one must gage what type of spam and what type of lists to use very carefully because of the possibility of refusing valid mail?
Is the implementation of using a DNSBL definitely something mail server administrators should consider?
Is it common practice to use spamassassin and DNSBL together to reduce bombardment of spam?
Although I have been using spamassassin for some time and see that it does a very good job of filtering and correctly labeling mail. Also the majority seems it could be prevented altogether by implementing the correct DNSBL or DNSBL's at the mail server level as I can see by spamassassin headers.
One thing I have heard is that it is not a good practice to put into effect something like this because many bigger institutions can and periodically do get put on blacklists, through no fault of their own. One example I have seen: https://www.stanford.edu/services/email/antispam/blacklist.html is this an accurate representation of some of the possible effects of this being put into practice?
Any recommendations as to suggested best practices in using these measures?
Thanks,
