OSDC 2014 (Gold Coast QLD) Call for Papers now open!

-------- Original Message -------- Subject: [Linux-aus] OSDC 2014 (Gold Coast QLD) Call for Papers now open! Date: Sat, 31 May 2014 10:32:28 +1000 From: Arjen Lentz <arjen(a)lentz.com.au> To: linux-aus <linux-aus(a)linux.org.au> Hi all We're looking for presenters to talk at the upcoming Open Source Developers' Conference (4-7 November 2014, Griffith University Gold Coast Campus, QLD). Register on the http://2014.osdc.com.au/ site, and propose a presentation. You can submit as many proposals as you wish, and come back to edit them later, so why not get started today? We have space for sessions, tutorials, hands-on workshops with keyboard or soldering iron (or both!) and yes, Miniconfs. Speakers attend the conference for free; travel and accommodation is still your own gig, although we may be able to make arrangements in some special cases. Initial CfP period closes midnight Friday July 4th, but you only have to get your abstract in at this stage, after that you've got quite a bit of time to prep your talk or workshop! Focus ===== While OSDC will be host to a wide range of presentation topics, from running an open source business or community, to more technical presentations, the overall conference theme for 2014 is Open: Open Source software, hardware, data and standards (protocols) enable higher quality, more secure products, and faster innovation. Inclusive: Openness enables and encourages exploration, the foundation of education. Making products accessible to for instance vision impaired people becomes easier. Affordable products are available to those with less money. Women, kids, and many other groups can get involved more easily. These are all opportunities, we must still work to make them happen! Connected: The last 18 months has seen a tremendous rise in the development of connected hardware, the connected home, wearables and sensor equipped devices. Contribute! =========== Remember, we have ample space for sessions, tutorials, hands-on workshops with keyboard or soldering iron (or both!) and Miniconfs. Go on, put in your cool ideas today! http://2014.osdc.com.au/ Cheers, Arjen.

Ques. re SSD drive
by Terry Duell 29 May '14

29 May '14

Hello All, I am about to make some hardware upgrades to my Linux box, and one of the possibilities is to add an SSD drive for /, /boot, and possibly also swap. Anyone have any advice on potential issues with the above? Cheers, -- Regards, Terry Duell

I have my netbook running with Ubuntu on a SSD drive for a year or so, without problems so far. The swap gets used occasionally, the netbook has 2GB only and I am running a X11 desktop (usually Windowmaker) on it. Regards Peter

IP is Layer 3 while Ethernet is Layer 2, which is all most switches do. Ah OK. I stand corrected. There's definitely some mechanism that lets a jumbo-frame client talk to a non-jumbo-frame client via a switch though. I swear I do this and it Just Works(tm). Perhaps MSS at the IP layer then?

That doesn't seem to fit my clients' needs because it's PCI and because it appears to only provide the aggregate performance of a single GigE port. PS If anyone has GigE cards they don't need (either PCI or PCIe) then I'd appreciate donations. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Jumbo packet forwarding
by Russell Coker 27 May '14

27 May '14

I've got a network with performance problems at GigE speed and would like to use jumbo packets. The problem is that there is some 100baseT gear on the network. What's the best way of using a Linux router to solve this given that I don't want to change IP addressing? I'm thinking of changing the addresses of printers (which I think includes all 100baseT gear) from 192.168.0.x to 192.168.1.x, adding all the old printer addresses to the GigE port on the Linux, and then using DNAT rules to forward the packets to the new printer addresses (which will be on a 100baseT switch on a different Ethernet port of the Linux box). That way I don't need to reconfigure everything that uses a printer. Is there a better way? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

compact usb wifi
by Bianca Gibson 27 May '14

27 May '14

Hi all, I'm looking for a compact USB wifi card for use with a laptop. Unfortunately the internal wifi on my work laptop (13" retina macbook pro) is pretty flaky under fedora. My priorities (in order) are: - reliable under fedora - compact enough I can leave it in at all times, including while transporting the laptop - decent range. My temporary borrowed USB wifi is pretty slow in the corner of the office. Any recommendations? Cheers, Bianca

Proceeded to compile kernel and modules - without error. Followed steps in attached file. Fails to boot and because I have no access to u-boot prompt am unable to troubleshoot.

I have never used one and have resisted the temptation so far... but don't these smallish wifi usb adaptors tend to have poorer performance in weak signal condition, given their small size and hence smaller antenna size? They may be ideal when signal is strong, but as Bianca said, she has slow reception in the corner of her office, so signal might be weak at that spot? Daniel.
