Re: [SLUG] Linux and Apache limits on number of files in a directory

Also, any idea what happens if you hit the limit? --- While I now the limit on a directory is very large it is NOT a good idea to fill it. I had major performance problems on a system that recorded every file into a single directory. I found that performance improved substantially just by structuring a couple of subdirectories. If you look at cricket archive it uses a magic number for every player, there are possibly close to 1 million players by now (700,000+ last time I checked). It uses grouping of 1000 to reduce the number of entries that it searches. so 0/900, 1/1789, 214/214759. When I downloaded the players in a single directory on my computer after download the directory management took it toll on my application, following the same directory structure had a massive improvement on performance, a simple divide gave me the directory.

Re: [SLUG] Android-based smartphones - any drawbacks ?
I owned an IPhone for a number of years and recently got a android galaxy II. First comment is that they are all slippery suckers. 16 year old has destroyed a number of phones just by dropping them out of his pockets. Deep pockets are a must (that is literal). Look after them and don't drop them. I drowned one and apple replaced it for a reasonably cheap fee ($250 at the genius bar) a definite plus. The iPhone has some great features however over a period of time the software burdens your phone and it simply stops working because it is overloaded. Call pick up does not work at times (iPhone 4 the same) When I bought the iPhone I thought laptop tethering would save me a 3g modem, I unfortunately went with Optus who charge to allow access, I have since moved to Virgin that does not. So read your plan. also look at the chunks they charge in, virgin charges in small increments, others charge for a large chunk even though you use a small one. It is definite that Telstra has the best coverage, Optus (hence a few others like virgin) are OK and Vodafone is the worst.For example Heathcote to the city on the train with Optus internet does not work about 50% of the time, especially around Oatley station. So make sure you have good 3g coverage at work and at home. Wifi is essential, my iPhone 3gs just stopped connecting, heard the same problem from a number of other people as well. Upgrading apps on Wifi and searching is so quick. I also decided the camera was important, your needs may vary but I never have the camera when I need it. Flash and a good pixel size is important, 8+ depending on what you want. Screen, the larger the better the galaxy SII is huge, so you better have big pockets. The screen is crisp but battery is terrible. I installed a juice defender and it is now far better. I find the screen on the galaxy better than the iPhone. Read a document with small text to compare. Android negatives. Calling seems more cumbersome than the iPhone. Android favourite is a name you then have to pick a phone number, IPhone is a number that just dials. You seem to be left alone a bit when you are setting up your phone, iPhone seems to be better documented / easier. For example how do you get spell correct to work? Samsung KIA did not install on Windows XP, worked on Windows 7. So the setup utilities are not as good. ITunes is much easier to drive than KIA. Notice that most people hate KIA, not surprised. email is not as friendly. Changing password on exchange account is not automatic like it should be. Reading the internet other mail clients are better, not bothered yet. Mail purges off when you pull all your mail on your desktop, so it is harder to keep those notes for later. Still have not figured out cut and paste. Overall I am very happy to have switched and I love the big screen and can put up with the bad battery life.

Re: [SLUG] Ubuntu 11.10
Can someone run through Unity at Slug in detail as a talk. This new interface certainly needs a sales pitch for me. I switched without problems from KDE to Gnome, Windows XP to Windows 7 so why do I need help to work with Unity yet it is 'better'. Ken Jeremy said... That’s because the feature has been removed. GNOME Panel is but a shadow of its former self. Those suggesting that you use GNOME Classic are either idiots and don’t think you need such functionality, or haven’t bothered using it for more than about 5 minutes to find out that it’s watered down so. To be fair, I don’t think that the GNOME team actually intended for anybody to use Classic on a daily basis. Rather, I get the impression that it is only useful as a recovery environment if compositing isn’t working. You should either use the full GNOME 3 including GNOME Shell, or continue to use GNOME 2 until you feel you’re ready. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

The feed mechanism is a LOT better, for huge volumes it is worth it. Image capture was always a challenge. Since I scan and mail on crappy printers at low res for bank use (my banker accepts scanned signed documents for some things). Mostly it is not that important.

Reply stripped. Andrew, I have to say that your reply was little to do with the direct offer of help. As a long term member of slug your reply does not represent my views in any way. Your reply seems at odds to Open Source principals talking of contractors, etc. (Yes we all have to eat but it is not the purpose of slug.) I understand the issue of rooms with the demise of progsoc at UTS. Slug should work together for a better proposal to a govt organisation, and I am open to helping with this.

Michael, I have gone to Google on the docks by catching a train to Town Hall and walking down. It really is not far. So public transport is not a problem really so long as you can walk a moderate distance. I cannot attend on Friday and a lot of the old members have moved states or are just too busy with life but stay with the list, so you might not know a lot of the people there. Regarding your help on the website. Technically there is a lot of help available for website, content is king and without a clearer indication of what you want to change then it is probably hard for the committee to see what your are proposing. What I have seen work is a mock up of something that everyone could comment on. Regardless whether this is accepted it is a good exercise for you.

Unfortunately this incurs the penalty of copying everything, every time (unless I missed something). Hence the desire to use rsync. I guess if I didn't do anything special (like encrypting) the tar ball, rsync could still handle the deltas with a certain degree of efficiency, but it would mean doing an update on the tar file each time. Total data requiring synchronisation is approx 12GB, every 15-30min...that's a heck of a lot of I/O and network bandwidth if rsync doesn't do a stellar job. I also noticed a --super option in the rsync manual, but I don't really understand how this works or what it achieves. On the upside, I've had an e-mail discussion with the notoriously suspicious Security Team and they have agreed (in principle) to relaxing the no remote root login by allowing the use of PermitRootLogin Forced-Commands-Only in sshd_config coupled with the method described here http://troy.jdmz.net/rsync/index.html - sanity and sensibility prevail.

Open Source (not as a name) existed in IBM in the old mainframe systems. Systems Programmers, who are now systems administrators, were hard core programmers. IBM had (from memory) Share tapes which was supplied by an independent group of users called share(?). Programmers wrote useful utilities and sent in this code. The code went to the various systems programmers on tape who used this code, enhanced and sent it back. This code was shared between sites. I think that TSO (Time Share Option) started like this originally however I may be wrong. TSO was a command line for Mainframe which was batch oriented until then, yes punched cards. Systems Programmers also worked on the Operating System itself. While it was proprietary the source was supplied and the Systems Programmers patched the source and returned the patches to IBM. I believe that the reason it became the most stable system available was the bazaar of programmers on installed systems, not the cathedral of IBM support. As a sideline the source was effectively stolen by another vendor who created a competing system. There was a lot of politics and there was a really strange settlement. IBM was forced to share the source with the other vendor by the US government.

So I thought I'd throw it out to the collective wisdom of SLUG. Here's the full story. We have a SuSE-based production application/DB server pair and a corresponding pair in a disaster recovery location (offsite, bandwidth consumption needs to be minimised). We need to sync a number of files between these servers and some require elevated (root) privileges at *both* ends. Here lies the problem; we don't allow remote root logins (via SSH or any other method either...sudo, console or nadda). I want to use rsync because of it's ability to transfer differential/incremental changes and thus bandwidth friendly, however any other tool would be fine too. However, due to the inability for root to login directly, how the heck do I synchronise particular files in privileged locations (like /etc/shadow)? I can start whatever services I need at either end (like an rsync server) but the main thing is all files maintain the same owner/group/mode at each end. Ideas? I have done this using sudo. I write a script on the called machine, sign on as my user and run the script using sudo which I authorise (very specifically) to root without password.

The box is a blade server, Xeon Intel board. In the Raid setting the drives are still recognised independently in Linux so it is not a true raid set up.

Quoting Daniel Bush dlb.id...@gmail.com: 2009/5/15 fos...@tpg.com.au - LVM is really cool and well worth the time to rad up on it. I am now going to LVM my home system. I'm planning to do this as well. I was thinking back to Mary's backup post last year and thinking if I could do lvm snapshots with an external harddrive. Still a bit new to lvm though. I think you have to install the alternate ubuntu cd to get lvm right? (unless you are using the server install instead of the desktop). The distinction between desktop and server in ubuntu is an install option not anything else. To add lvm to your existing system just 'apt-get install lvm2'. To convert an existing setup to lvm you have to have some free space (partitions or whole harddisks to use). First create a volume group (chunk of hardisk spread across one or more harddrives) sudo lvm pvdiskscan pvcreate /dev/yourpartions vgcreate vg1 /dev/part1 /dev/part2 create a logical volume somewhere in that volume group (say 300 gig named yourname in vg1) lvcreate -L300G -n yourname vg1 You can then mksfs.ext3 /dev/vg1/yourname (replace ext3 with whatever is appropriate) and then mount it. Snapshots I cannot vouch for snapshots. There is something different lvm1 and lvm2 for snapshots and they cannot be used V1 to V2, since I am not using them I have not done any further reading. I think gparted can be used to manage LVM after it is set up. I cannot verify this though. You can add hard drives from the VG once you have created it.

[SLUG] cannot boot Ubuntu with bios raid setting
I have a machine with 6 Harddrives sda = sdf and when I install Ubuntu desktop it will not boot. There is a bios setting for raid and if we set this on we see all 6 harddrives but the install will not boot. If we set it to not raid we see 4 harddrives and it will boot. Any suggestions?

I notice you omitted the section of my email where, indeed, I note that this is from practical experience. Sorry, but ROX and GNUstep are experimentations. They don't have users or vendors or real systems they need to integrate with or previous version compatibility issues, etc. When I say reality, I mean products shipping and an active marketplace around them (which *can* be said for GNOME/KDE). Then the hairier issues of software support beyond hey does this stuff work? start to bite. This appears to diminish the experiments that do occur. I can agree with your generalisation however we should not minimise any effort on FOSS, even experiments. What about those scheduling experiments on the kernel, ultimately led to a major performance improvement for me personally. The problems with packaging really are not with the software but with all the prereq management. This is the strength of debian apt, not so much the install code itself. This does not minimise the complexity of the code itself but just where the true effort was in the first place. People often think a program is the solution, often the data feeding it is much more important. Think Redhat before they began merging Debian prereq information, it was really problematic. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
