EFA's Creating the Web We Want
by Jacinta Richardson 02 Jun '14

This might be of interest to some folk. Electronic Frontiers Australia, in partnership with ThoughtWorks Australia presents: Creating the Web We Want * Time & Date: 11:30am, 17th June 2014 * Venue: Melbourne Convention Centre, 1 Convention Centre Place, Southbank (click for map) <https://www.google.com.au/maps/place/Melbourne+Convention+%26+Exhibition+Ce…>. * Cost: FREE * Registration: Not Required Speakers * Keith Dodds <https://www.linkedin.com/pub/keith-dodds/0/410/a82> - Director, Client Relations, ThoughtWorks Asia Pacific (Moderator) * Senator Scott Ludlum <https://en.wikipedia.org/wiki/Scott_Ludlam> * Jon Lawrence <https://www.efa.org.au/about/board/jon-lawrence/> - Executive Officer, Electronic Frontiers Australia * Tom Sulston <http://au.linkedin.com/pub/tom-sulston/0/411/178> - Principal Technical Consultant, ThoughtWorks Revelations from whistleblower Edward Snowden have clearly demonstrated that governments around the world have been engaging in dragnet-style mass surveillance for years. We know that intelligence agencies, including the US National Security Agency (NSA), the UK's GCHQ and Australia's Signals Directorate have been intercepting and storing the records of hundreds of millions of our phone calls, text messages, emails, web searches, website visits, instant messages, and social media activity. We know that these agencies have been sharing our information with other governments, large corporations, and non-security organisations. Governments have justified this mass surveillance on the grounds of "national security" against "terrorism". Yet there is no evidence that this disproportionate intrusion into our private lives has stopped or foiled even one terrorist act, despite the vast financial and social cost. What these government activities have done is to build an extremely effective surveillance infrastructure which police states of the past, present, and future could only envy. It is our duty to redress this illegal and immoral societal imbalance. What legal, social, and regulatory policy reforms are necessary to safeguard our right to privacy? What can we do both now and in the future to protect our private communications from dragnet government surveillance? What level of digital spying is acceptable in an Internet where our privacy is valued? This free and public forum is part of the Agile Australia conference. It will be a thought-provoking examination of privacy issues vital to the future of digital freedom. It will include a review of available technologies to resist dragnet surveillance, and global initiatives to strengthen individuals' right to privacy, as enshrined in the 1948 Universal Declaration on Human Rights. It will be a call to join and shape local and worldwide activities to oppose mass government surveillance. More information: https://www.efa.org.au/events/web-we-want-2014/

10GigE
by Russell Coker 31 May '14

31 May '14

Has anyone had any experience with 10GigE? I'm not after anything at all complex, just a single server that needs something a little faster than GigE talking to a single switch that can spread the bandwidth over 12+ GigE ports. As an aside, I think it would be nice if someone developed an Ethernet card and switch as one combined device. It would be a PCIe card that looks to the system like a regular Ethernet port connected to a 4 port switch with the only software visible difference being that it had 4* the bandwidth of a regular Ethernet port. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

OSDC 2014 (Gold Coast QLD) Call for Papers now open!
by Daniel Jitnah 31 May '14

-------- 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?

You want a 4 port Ethernet card with > wire speed switching :) Actually that could be really handy for my home network which is 100baseT because I don't have much need for greater speeds and because the core of my network is a P3-800 running Linux bridging. 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
