[SLUG] Re:LaCie 2TB 2Big Dual + debian (LaCie SATA II PCI-Express eSATA cards)
I had an ESata card with cables ( bought in Japan) that let me attach a caseless SATA hd directly to the PC. Worked fine under Kubuntu 6.06 until the mobo went up in smoke. On another note, I'm currently running Kubuntu Hardy and cant get it to recognise HDs correctly when I have both IDE and SATA hds attached, so check that your hardware doesnt have similar problems. Another problem that has arisen ( on another PC but identical mobo ) is an Error 15 after clean install - from info on Forums, this may be due to same problem and install placing MBR on wrong HD I posted re the IDE/SATA problem within the last couple of weeks.

Every external firewire/usb drive i've used has ended up giving me hard drive failure, and in some cases heart failure. Other people whose opinion I respect have come to the same conclusion. I get the impression that the problem has to do with power supply on the external device, but I haven't figured that out for certain. I haven't used Lacies.

[SLUG] CFP: Foundations of Open Media Software Workshop 2009
Call for Participation Foundations of Open Media Software (FOMS) Developer Workshop Thursday 15 - Friday 16 January 2009 Hobart (Tasmania), Australia http://www.annodex.org/events/foms2009/ Important Dates: Submissions open: 11th June 2008 Submissions close: 15th August 2008 Notification: 30th September 2008 What is FOMS: Foundations of Open Media Software (FOMS) is a developer workshop to widen cooperation and interoperability among open source media projects. Meet and discuss your plans for the next 12 months and forge relationships with other developers to unwind the kinks, making open media kick ever more ass. This is a call for participation in the third FOMS meeting, which will be held in Hobart, Australia over two days in January leading up to linux.conf.au 2009. The FOMS meeting is organised by developers for developers. FOMS caters for developers with topics of interest in and related to: * open audio & video codecs * open audio & media frameworks * audio infrastructure * web video (HTML5 audio/video) and crossover with open source * mobile video * open audio & video applications * open metadata * open media standards The proximity to linux.conf.au allows us also to discuss audio- and video-related issues with the developers of Open Source kernel, networking and desktop systems. How to attend / submit: FOMS attendees will be developers of open media software from the community as well as professional delegates from companies with a background and interest in this space. The attendance fee for professional delegates is A$420 - community participation is free. Attendees are expected to have a background in open media software. If you would like to attend, please contact foms-committee(at)lists.annodex.net and tell us why you should be there. Also mention if you require travel assistance. Coincident Conferences: Since FOMS2009 is happening the week before linux.conf.au, in the same city, you may want to consider submitting a proposal for that conference as well. Travel Funding: FOMS highly values it's developer attendees. FOMS has provided a limited number of sponsorships for travel funding for the best developers since it's beginning. Further travel sponsorship can be achieved by being an accepted speaker to linux.conf.au. The Linux Foundation also has travel sponsorships to important events like FOMS and LCA. -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Would not it be better to (1) define the problem (2) define solution(s) (3) implement rather than jumping in with both feet and squarabling for a solution? EG I've got video systems recording divers on an oil rig. Power, waves, power, power and power are grave issues. I boot RAM fs from RO squashfs image with write of video data to flash/disk. This works very well, but is very tailored to this specific need. EG you could easily implement a battery-primary system that would never have a power outage and lead-acid batteries are marvelous sinks of noise. There are numerous ways to achieve this even normal power supplies that are 12v or 24v input. etc James -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Hi Rick, Quoting Rick Welykochy <[EMAIL PROTECTED]>: I've always pondered where to draw the line between sys admin and programmer /analyst. Well there's definitely a difference... but there are true sys-admins, true programmers and some who seem to be able to do both.

But it is painful for me seeing days of list debate for something that could be fixed (by a programmer) in an hour at the cost of a six-pack of german beer. :-) As an aside, my brain begins weeping when I have to do something novel with iptables (another command-line monster) but I don't consider that a programming job. I get the impression many Linux admins can configure iptables in the dark without a keyboard and both hands preoccupied with beer and pizza.

Erik de Castro Lopo wrote: Does anyone have anything else to suggest? mount ext3 with options: journal=data,barrier=1,noatime,user_xattr Create the fs with a bigger journal than usual, this will improve performance with journal=data. Our scientists often forgo filesystems entirely if the application is simple (eg, data collection). For example, they'll zero the partition at the start. To record an observation they'll seek to a position based on the time (or observation number reported by the data hardware) and sync write the fixed-length observation with a checksum. Note that Linux's performance with sync-ing is poor on a multi-use machine (since all buffers are synced, not just the application's buffers). Note that barrier=1 won't work with LVM or DM, you need a real partition. You might want to consider a distro like OpenWrt which minimises the amount of incidental disk I/O done by the distribution and allows a definite split between a read-only partition and a read-write partition. The the amount of read-write disk to be recovered will be smaller (since read-only partitions don't need recovery). -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
