But here we are admonishing the GNOME hackers had the temerity to do something new and different. ++ I've been using GNOME 3 full time for over 9 months, and I find it quite usable. Sure, it's different than GNOME 2. It's vastly different. But it *is* a new UI paradigm. The GNOME 2 experience was 9 years old, and the gnome hackers have been working hard (since about 2007) to do something about interaction that the old Windows 95 paradigm simply couldn't address. Sure, I had to learn some new usage patterns, but I don't see that as a negative. It's a new piece of software, so I'm doing my best to use it the way it's designed to be used. Incidentally, I'm not sure how up to date it is, but you might have a read of http://live.gnome.org/GnomeShell/Design to see some of the things they had in mind. And of course there's lots of things linked off of http://www.gnome.org/gnome-3/ . Distros like Ubuntu have been shipping GNOME 2.32 for ages; but it has been well over 2 years since anyone actually worked on that code. It's wonderful that nothing has changed for you in all that time, [a true Debian Stable experience!] but I think it's a bit odd not to expect that something that was widely advertised as being such a different user experience is ... different. ++ I went to some trouble to run GNOME 3 during the Natty cycle; that was a bit of work but I needed to be current; now with Oneiric things are mostly up to date. GNOME 3.0 was indeed a bit of a mess, but then so was GNOME 2.0. The recently released 3.2 is a big improvement. And it looks like the list of things that seem targeted to 3.4 will further improve things. I'm now running GNOME 3 on a freshly built Ubuntu Oneiric system; I just did a "command line" install of Ubuntu and then installed `gdm`, `gnome-shell`, `xserver-xorg` and friends. Working great, and not having installed `gnome-desktop` saved me a huge amount of baggage. Of course a normal Oneiric desktop install and then similarly installing and switching to gnome-shell would work fine too. You probably want to enable the ppa:gnome3-team/gnome3 PPA. ++ One thing I do recommend is mapping (say) CapsLock as an additional Hyper and then CapsLock + F1 .. CapsLock + F12 as launchers. I have epiphany browser on F1, evolution on F2, IRC on F3 and so on. Setting up CapsLock + A as to do `gnome-terminal --window` means you can pop a term easily from anywhere. You do all that as "custom shortcuts" in the "Keyboard" section of system settings. That means I only use the whole "Win key + T R A C ..." thing (in this case looking for the Project Hamster time tracker) for outlying applications. Of course you can also set up the things you use the most on the "Dash" (I think that's what they call it) as favourites. I've actually stopped doing that [the original design didn't have favourites at all]; I prefer to have it as an alternative view of things that are actually running.

Well, not to be underestimated is that people have worked hard over the last 5 years to make Linux and their applications run well on 64 bit. Sure, there were many glitches early on. That's porting for you. But lots of hackers and early adopters (as they then were) put the hard work in, and now, many years on things work great. That's our luck.

The Pantone colour palate (specifically their name-to-ink-colour mappings) is Pantone's proprietary intellectual property and they have chosen not to let them be used in libre ways. [they make tons of money printing swatch books of the mappings and licencing the names. This is not dissimilar to the business model used by most font foundries, which is why there are so few libre fonts. The difference is that anyone can create a font, whereas an industry standard that is not an open standard with libre data is a bottleneck] As long as the graphics arts industry continue to use those names to identify, and the printing industry uses such names to distinguish the pile of coloured bottles on the shelf, then apparently there's nothing we can do. ie, we are free to come up with our own names for inks, release them freely, and manufacture said inks to our hearts content. But this doesn't do us the least bit of good until such time as such inks were widely available at printing houses as an alternative to the Pantone copyright ones. And that ain't about to happen. It's exasperating, but the names & mapping are their property. I think most people who need to would be happy to pay for access, but a) such a datapack would be non-redistributable, and in any case b) since people are used to getting it for "free" (in products whose vendors have already paid Pantone for a licence), people don't really get the idea that there's a cost to it. So maybe we need to go on a crusade to convince ink manufacturers to _also_ label their products with [some hypothetical set of redistributable] names, as well as Pantone ones.

As an aside, It is interesting to note that "maxing out" (1.0 on one CPU, 2.0 on two, etc) the load average does not necessarily imply the best use of a machine. I know the gent who runs the image farm at Amazon. Unsurprisingly, Amazon's high level IT people wanted all the systems to be fully utilized - but the point of the image servers is *not* to be running without any CPU idling, but to be serving images with extremely low latency. So in this case, they needed a very beefy set of machines that were running at as close to idle as they could so that any new request coming in could be acted on immediately. He had such a bad time of trying to explain latency to senior IT that finally he gave up and hacked the kernel so that it reported artificially high load averages to trick out the external monitoring agents so the IT managers wouldn't feel that they could lump more services onto the box, thereby increasing their "utilization" at the cost of completely destroying responsiveness.

Which is why it's so important for SMTP servers to guard against the possibility of being open relays. Certainly, greylisting can be circumvented by the evil doers simply injecting their messages to a legit nearby SMTP server, say, their ISPs which *will* properly retry. That, however, is easy for an organized ISP to track, hence those in the axis of evil writing SMTP clients that go direct to the server the target domain's MX record points at, which is why greylisting is a nice touch.

Re: [SLUG] Is there a truly upgradable Linux distro?
On Tue, 2006-06-13 at 13:45 +1000, [EMAIL PROTECTED] wrote: > in which numerous respondents say that Debian and Gentoo Those are the two that I have experience with upgrading over long time periods. Relevant to this discussion, I had one Debian upgrade continuously from 1998-2003 and a Gentoo system live and upgrading from time to time from 2002-present. Excellent success with both. To me, there is an important consideration: stable or unstable. In Debian's case, if all you ever do is run their stable releases, then you will find their upgrades smooth indeed. They are very focused on this. On the other hand, if you're needing more up to date code, I'd give Gentoo the nod. Because it is building locally as it goes, you are more likely to have everything just fit together. An instantaneous moment of bliss, to be sure, but it does seem to work out well over the long term that each such brief rebuild occasion results in a nice stable ticking-along system. [Frankly, I give credit to the free software universe as a whole, not to any particular distro. The combination of some distros pumping the leading edge and shaking out initial problems, others pulling bugfixes in from the enterprise installations, and things like GNOME and KDE working together (sic) through freedesktop and utoptia and other projects, practices, release cycles, and interaction have coalescing into a whole where everyone quickly benefits from the experiences of the others] Of course, Gentoo doesn't have releases, per se (they cut a bunch of install CDs with lots of precompiled packages to get you bootstrapped a few times a year), but in a continuous "upgrade something when I need it and rely on minimum version requirements expressed in the packages to cause deeper upgrades to happen when necessary" mode, it's been very reliable. What it means is that my attention is focused on the thing I'm upgrading, and the base system (whatever that might happen to be) is largely left alone to tick along. I wrote an article in Linux Journal last year about it, see: http://www.operationaldynamics.com/reference/articles/GentooUnusual/ if interested. > Perfectly smoothly? No. The only way you're going to get that is a blank system fresh install of something like RHEL, SUSE, or maybe someday Ubuntu where stuff has been extensively tested. And even then, it's "out of date" and frozen in time, so you don't gain a whole lot that way if, for whatever reason, you need a newer version that what your OS is currently providing. Really, the issue boils down to skill set - if you have the skills to watch for, detect, analyze, and resolve issues, then you're going to be fine on the continously upgrading testing/unstable distro versions (Fedora rawhide, Ubuntu whatever, Debian unstable, Gentoo unstable, etc). If you just don't have time for that sort of thing, then, to be perfectly honest, the strategy you have adopted of getting a system installed, configured and then leaving it alone for a long time is a fine one indeed.

Not every day a businessman decides to GPL his product. OODBMSes came and went as a technology in the late 80s/early 90s, so you might be saying WTF? Those efforts largely face planted because they tried to create a generic object syntax and a complicated meta query structure rather than working in the native syntax of {insert your OO language here}. db4o is really rather different. It is trivially easy to use and surprisingly robust. For me, working in Java on Linux as I do, it has given me a reliable persistence store for my applications without any of the usual object-relational mapping nightmare that would crop up if I were to try and use a more traditional RDBMS.

[SLUG] Infrastructure archictecure
Tonight at SLUG I mentioned the broader issues of the disciplines and practices involved in running a production platform. One of the fundamental pieces of background knowledge that's an important and canonical reference is a paper called "Bootstrapping an Infrastructure", which more or less established the notion of "gold server". Available as an living online document at http://www.infrastructures.org/ ++ For what it's worth, if you're interested in Gentoo packaging, I wrote an article on the topic that appeared in Linux Journal. See http://www.linuxjournal.com/article/7438 It's written somewhat deliberately to give non-Gentoo users who have some idea of the experience of packages and administering their own Linux distro an idea of the interesting ways that Gentoo has approached the problem space. There's a PDF of the article in it's original form on my site - IMHO it's typeset a little better :) Enjoy. http://www.operationaldynamics.com/reference/articles/GentooUnusual/GentooForAllTheUnusualResaons_Article.pdf AfC Sydney -- Andrew Frederick Cowie Technology strategy, managing change, establishing procedures, and executing successful upgrades to mission critical business infrastructure. http://www.operationaldynamics.com/ Sydney New York Toronto London -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Yeah, yeah. Ok, so I should have provided more context. I've chatted about this project with a few of the SLUG people that I see on regular basis, but for the rest of the mailing list: One part of my work focuses on managing massive changes & upgrades to mission critical systems.[1] I'm writing a tool to help me with that. Specifically: Right now, many of my clients do their procedures in clunky manually generated [paper] documents, but when a group is working through a procedure around a specific point event (say, replacing all the networking gear in your datacenter) there is an intense need for the people involved to collaborate and coordinate their activities. In essence, the problem is one of merging structure (the procedure to be run) and sequence (enforcing the fact that although a hierarchical document, it actually involves a carefully specified sequence of events, and that order must be enforced). See [2] > Are there other constraints, like the use of a specific programming > language on the client or the server, or a specific client or server > platform? No, not really (well, ok, it's not mobile devices - it's a client/server application), Trying to work my way through the various option spaces so as to make these choices has been quite the nightmare (er, "learning experience). I've made good progress, though. I actually gave a presentation about this last weekend... anyone who is interested and still reading is invited to have a look at: http://www.operationaldynamics.com/reference/talks/WelcomeToMyNightmare/ [Summary: I'm working on and for Linux, in Java + gcj, writing a GTK/Gnome app, and Berkeley DB is the back end data store. Wondering what the heck is up with all that? Follow the link, doh! And yes, It'll be open source] That presentation concludes with the specific technical problem that led me to start this thread in the first place: I am trying to decide on an appropriate middleware technology for a problem with these aspects: * Relatively small groups (5-15 people, typically) so low message volume. * Participants are distributed in space (some in the data center, some in the office, vendor reps, contractors, and specialists may be external) [so a solution that works reasonably well across complex network boundaries would be useful] * Events leading to messages, however, are extremely close in time (I check that I've done a step, you check you've done the step right next to it, we both need updates, happens in the blink of an eye, can't loose time from polling cycles ). * Very high consequence if things get out of whack (team is updating a mission critical system, yo!) so don't want to loose messages or history of progress through the sequence. Updates are idempotent, though, so receiving a message twice isn't a problem, which seems like it should help. Last weekend, Ben Ellis suggested to me that I consider XML-RPC. I don't think that's the solution to my problem, but man, what a clean API [3] Julio's suggestion of leveraging Jabber is really intriguing. Stewart Smith made a similar recommendation to me a few months ago, which I'd forgotten about. So, thanks Julio! There were a lot of typically murky complex Java APIs out there, but I found one which seems really straight forward, [4]. If I go down this road, could either build the server as an independent Jabber client, or hook it into a Jabber daemon as a Jabber component.

I was taught about oop in terms of > message passing: there is no conceptual difference between passing a > message and a 'remote object invocation'. Yeah. Indeed, I don't need the remote object part - I have the data model well under control. I just need to pass events. [yes, of course, a Remote Entity model DOES do what I need - just seems overly complicated is all] Given the relatively small size of the groups involved here, polling doesn't create a resource constraint issue, but it is inelegant at best, and certainly doesn't scale. No, the only real trouble that I can see is that in the wider public network context, the firewall problem gets in the way - clients can connect outbound to some server on the net, but (especially in an HTTP paradigm) the other direction doesn't fly. (oh, sure you can pass messages in response to a poll, but you can't initiate). I don't think I want to writ
[SLUG] Lightweight message passing infrastructure?
Quick survey: I'm building something that requires a lot of two-way (message/event) traffic between clients and servers, and could use some help picking a technology. The server->client direction is tricky in conventional web (and web- derived) models because it's always client request server response on the clients schedule (no good for passing messages from server to client, at least, not without client polling type behaviour, yuk). XML- RPC would have been perfect except for that. Given how absurdly simple and clean the Java APIs are, I may use it anyway. Someone at SAGE-AU suggested I consider ICE (an next gen CORBA, see http://www.zeroc.com/ ). It's pretty impressive, but seems like an awful lot of framework for what I would have hoped would have been a simple implementation, especially considering that I view the problem in message passing terms, not remote procedure calls or remote object invocation terms. That said, the scalability, availability, and just- works factor (once implemented) is alluring. In the Java world, there are obviously lots of frameworks, (ranging from J2EE EJB containers down to small things like picocontainer) but I don't really want a container at all - managing lots of objects, and persistence, isn't the problem I'm trying to fight. Further, I'd like the server to be a relatively stand alone thing, and containers introduce pretty massive installation headaches. OpenJMS would be good in theory, but it's very heavily J2EE based, and brings all that baggage. Any suggestions welcome.

You know, that's a good question to ask. I used to think that running a Windows server in a production environment was ridiculous. But there are lots of people who do so. Of course the reason for that is that XYZ application they need works there. Oracle, for example, doesn't really care whether it's running on Windows, Unix, or Linux [quite impressive, really]. Certainly, there is a lot of software in the ERP and business analysis space that [has to] run on Windows Server. People with Unix/Linux backgrounds are accustomed to administering machines remotely and likewise used to doing things via command line interfaces. But in a large in house corporate data centre, people sometimes (for legacy reasons if nothing else) have the infrastructure they need to KVM large numbers of machines. To the actual performance question: I imagine that the assumption is that running an X server on a machine that "doesn't need it" is wasteful of resources. Certainly if you're *using* that X server for a graphical user environment, you'll be generating a lot of load that will detract from the horsepower available for real services. The assumption would seem to be that since a Windows server needs to run it's graphical environment, whereas a headless (presumably implying X -less) Linux box does not, a Windows server must under-perform a Linux one. I'm not so sure how much the GUI matters in reality. I think the real key is "using the graphical interface". While X is a large beastie, to be sure, if it's just sitting there not doing anything then a lot of it can get swapped out - and will be as more active server processes consume resources. Which all makes me think that a Windows server's GUI may not be as much as a penalty performance wise as we might think. It would be interesting to find some unbiased statistics about all that. Another domain, Java VM performance, shows Windows servers doing just fine. From a year ago: http://www.volano.com/report/ Doesn't mean I would recommend Windows by any stretch. I'm an operations guy - the ability to remote administer farms of Linux systems and the ability to finely control system layout, activity, and performance is the critical differentiator.

Unless you have a large production platform (in which case you have to do migration and regression testing before deploying something as fundamental and core as a new JVM), you'd do well to quickly move to whatever the latest release from Sun is [assuming you're using their JVM]. Note that, especially on Solaris, JVM stability is typically achieved in the x.y.[1-3]_0[1-4] range. They have a lot of enterprise users, and people flush out the significant bugs pretty thoroughly.

You said you've used qmail. That probably means you've used daemontools as well. If you're comfortable with (and using) svscan/svc/multilog/etc and the whole /service symlink thing, then plugging djbdns in is a snap. We used it for a while - in fact, our use of it predated qmail; I think that was part of our problem - we didn't quite know what were doing with daemontools at that point, and that meant that we screwed up a few things (like forgetting to regenerate .cdb files, etc) which meant that our satisfaction wasn't as good as it might have been. That said, I'm really impressed with djbdns (and dnscachx which goes with it). It's a bit of a learning curve as is usual with DJB's stuff (what is it with that guy compulsively making hard to use software?) but the fact that it automatically generates the PTR records, for example, is terrific.

Without wanting to be pedantic, I got this wrong enough times to offer a minor clarification: A great way to figure out what your system is doing is to put echo "In ~andrew/.bashrc" 1>&2 As a line in your .bashrc, and similar lines in places like .bash_profile, .profile, and if you're really stumped, /etc/profile, .gnomerc and /etc/X11/gdm/gnomerc (but see warning [1] below!) Sometimes you'll be surprised. For example, I was once dealing with Solaris boxes whose default shell wasn't bash. I wanted to use bash, and so would do ssh [EMAIL PROTECTED] bash [assuming bash was even on default path, ] The thing that surprised me was that, *I* thought I was "logging in", but in this case, .bash_profile wasn't run, only .bashrc . This because running bash as the command via ssh is the same as if you just type `bash` on a command line - .bashrc gets sourced, but not .bash_profile. . As you may have noticed, one of bash's options is --login (this is what relates to the `su -` conversation). It turned out that if I wanted .bash_profile to run, I needed a "login environment" and so needed to amend the above command to ssh [EMAIL PROTECTED] 'bash --login' which was a bit of a pain. [So I wrote a wrapper, but that's another story ;)] So this is all to say that, especially with bash as a shell (but I suspect many others), it pays to a) put environment setting/creating things, like setting PATH, in .bashrc b) put login only things, like checking new mail or changing directory to ~ or running a clock or ... in .bash_profile; c) go to the effort to actually *get* a login shell when you want one. Note: Interesting how the default skeleton .bash_profile always sources .bashrc for you! That's because if bash IS in login mode, and decides to source .bash_profile, it DOESN'T source .bashrc automatically as well - so if you're environment settings are there, then you need to act to get them. -- [1] WARNING! Don't forget that since .bashrc gets sourced any time a shell runs, it REALLY must not output anything on stdout - in other words, that little debuggy statement I suggested above will wreck your world if it *doesn't* go to stderr and you try to do `scp`. So don't forget 1>&2 on any debug lines Ah, the things we learn by trial and error. Given that this is all open source and subject to modification without notice, your mileage may vary.

Jeff's got you on the right track, of course, but I would suggest also that you have a look at the evolution mailing list archives. This sort of question comes up (sadly) quite regularly. http://lists.ximian.com/archives/public/evolution/ The "sadly" comment is there because the IMAP code in evolution is *REALLY* weak. This isn't just a matter of my opinion - it's a loud and constant complaint from evolution users. And Ximian knows this. I've had long talks with Ettore (and even Nat Friedman) about it, they know it needs fixing, but for some reason it never quite makes it onto the radar to get fixed in a given milestone release - the UI work they've been focused on continues to take priority. Nat told me they're serious about finally addressing this problem either in 2.0 or shortly thereafter. We'll see. In the mean time, if you get really frustrated I would recommend using something like offlineimap which groks IMAP really well and mirrors your server's mailstore to a local tree of maildirs.

I switched to using Gentoo about 9 months ago, partly for technical reasons (not the ones you'd think, see below) and partly because I thought that *someone* on the Linux Australia committee should be using something other than Debian [Ok, Leon uses Mandrake :)] There are, it turns out, quite a number of Gentoo people in Australia. I'm working on encouraging the ones I come across to join in with groups like SLUG, LUV, HUMBUG, PLUG, etc and to attend events like LCA. If you want to "try" it, expect a learning curve; the same that you would have switching to any other distro. One tends to do a lot manually on a Gentoo installation (for example, if you want to change timezones, you probably are going to be changing the /etc/localtime symlink yourself). It's not exactly hard - and great fun for anyone who likes doing a lot themselves. It *does* have it's own ways of doing things, notably around rc scripts and building packages. Both are excellent. The technical reason I'm still using Gentoo is not for the performance optimizations that may or may not accrue from compiling things with specific optimization flags, but rather that I find the packaging system (specifically the files used to describe how to build packages) to be deliriously easy to use. I work in a number of environments where I need to rebuild specific packages to my requirements, or quickly package local software to be rolled out across a number of machines in a production environment. I find it really easy to integrate my own work into the machine's existing package management system. That counts for a lot for me. As a side note, I expected Gentoo to be a nightmare to maintain. We've all lived through the occasional nightmare episodes when tracking Debian unstable (like breaking lilo, things like that) and given that Gentoo is a similarly moving target, I expected it to break all the time. Much to my surprise, it doesn't. I *don't* just madly and blindly update my system automatically each night or anything like that, but I do find that when I upgrade specific packages the dependency graph stays on top of things... between that, proper library slotting, and ./configure working it's magic, It mostly Just Works (tm). :) One last little tidbit. Using Gentoo, one maintains (in a /etc config file) a list of the various "kinds" of things I'm going with my system. For example, I've told it things like "gnome -kde java -ldap". The build files take account of these settings, and adjusts ./configure settings accordingly. So, when using Gentoo, you're not locked into the decisions about settings and capabilities made by, say, a Debian package maintainer. All adds up to a lot of flexibility and a lot of power under the hood. But of course, that's also the case because it's Linux. All good. I've prepared a presentation called "About Gentoo for people who think its a crazy idea". It's on offer as a SLUG talk if anyone is interested. > If you dont mind having it download and compile for a day or two it is > fast and tastee! Gentoo has a [mostly] working binary package system which integrates tightly with the normal filesystem management done by the packaging system. I recently built a server and for comparison tried downloading Gentoo's CD images (1 x CD-ROM to get you going up to and including X windows, and a second one with a pile of [optional] binaries (Gnome, KDE, etc)). Downloading the ISOs and then updating my build description tree resulted in some wasted downloads in the more fast-moving software, but many things are pretty static over medium time spans and so the binaries made a few weeks/months ago are pretty good. Not having to build gcc, glibc, xfree, etc right off the bat meant I was up and running really quickly, downloading and compiling specific ebuilds as needed as I moved forward. After about a month of running the system, I'd say that I've needed/wanted to upgrade (ie downloaded source + compile + merge into system) about only 30% of the packages. That's a slow and quiet background trickle, really and as for system impact? There isn't any. That's what nice(1) is for. AfC P.S. I don't care if the original poster was trolling, as some suspected.

I use it exclusively as a fax and copier, so I can't tell you whether it's any good under CUPS, I'm afraid, but it does seem relatively robust.

Sounds to me like xdm [or kdm or gdm or whatever] isn't running, or if it is, it's not connected to [or a child of] the X server you have running there. But, see below... > I cant help you exactly with your problem - if there is one... BUT... I > can tell you that VNC on linux is much different to that on windows.

You can achieve the remote-control aspect you're looking for under VNC, but you need to run a program which exports your X display as a VNC stream. There was such a program, called x0rfbserver , available from http://forum.hexenet.de/ . That site, is however, off the air, and the freshmeat entry is gone (WTF?!) I corresponded with [EMAIL PROTECTED], who reported that he was aware it was [temporarily, he hoped] gone upstream, had taken action to keep it in the Gentoo mirrors. It's a package called "rfb". So you should be able to find it by looking for /distfiles/rfb* in the Gentoo section of any major mirror. [Here in .au, I've been using http://mirror.aarnet.edu.au/pub/gentoo which is a mirror of http://www.ibiblio.org/pub/Linux/distributions/gentoo . I'm not sure what Debian or Red Hat call the package, if anything] If you're not looking for remote control, but just want to access an X desktop, you can do that. I think you're on the right track, but you need to additionally run an X server (which will in turn need to have an xdm/kdm/gdm on it) and have a VNC program attach itself to it.

It will be interesting to see if this continues. Andrew Tridgell remarked to me a few months back that it used to be that the Samba team could get answers from Microsoft Engineering - in fact, the two groups had a decent relationship and the Microsoft techies appreciated that the Samba group were finding bugs in SMB implementations under Windows. Apparently, in the last 18 months, this activity has cooled off dramatically - as Microsoft has come to realize that Samba is a key component enabling heterogeneous networks - and therefore a "direct" threat to them, the word has gone out inside Microsoft that supporting Samba is not cool. It will be a shame when Microsoft corporate comes to realize that Mono et al are a direct threat as well; I can't imagine them acting any differently in that situation. Oh well.
