Edited excerpt from the auto-generated transcript "it turns out the instruction set and the core of the CPU is not very important and and it's one of those big differentiating factors that people kind of fixate on but it really doesn't matter very much in the end. What matters is all the infrastructure around that instruction set and an x86 right now has all that infrastructure and it has it at a lot of different levels. ... I tend to look for is making if you want to make big progress in a specific area you need to figure out how to make lots of people care about that specific area and and that's the problem with small devices right now is it's really hard to find lots of people to care when most of the small devices you can buy tend to be very locked down for example and and I'd love to say that there's millions and millions of IOT devices that there should be tons of people caring about them but if all these IOT devices are actually hard to play with the only people who end up caring about these are inside companies and it's really hard to get a personal interest in small hardware when none of the small hardware really tends to encourage that kind of loving"

Beginner's meeting topic
by Andrew Pam 03 Apr '17

03 Apr '17

Thanks to David Turk for suggesting node.js as our meeting topic for March. We're still looking for a presenter or a topic for the beginners meeting on Saturday 15 April, so please feel free to suggest something! I was tempted to send out an email on the 1st offering a talk on "upgrading your Linux deskop to Windows 7 Professional", but it's probably just as well I resisted. Cheers, Andrew

Viewing iView and flash
by Mark Trickett 28 Mar '17

28 Mar '17

Hello All, I have been told that I appear briefly in Bespoke on ABC TV, in particular seen on last Sunday the 19th. I have gone to the ABC TV website and gone for iView, or via the program guide, and tried to watch, only to have it stall complaining about flash being required. This is with ESR Firefox on 3.2.0-4-686-pae #1 SMP Debian 3.2.86-1 i686 GNU/Linux/Wheezy. I know some others do manage to use iView running Linux, comments about how appreciated, as would be someone grabbing and saving as a less unfriendly format, the latter even more appreciated. I will also look for a way to let the appropriate people at the ABC know that flash is inappropriate for many reasons, particularly the security vulnerabilities. Regards, Mark Trickett

PCs

I could just give you a dual-core 64bit PC, at least 4G of RAM, and a pair of decent SATA disks in a RAID-1 configuration with the latest version of Debian installed if you can arrange transport for it. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

simple web proxy
by Russell Coker 23 Mar '17

23 Mar '17

Can anyone recommend a very simple web proxy that works reliably with apt-get (unlike Squid)? What I want is to just allow access to apt repositories and nothing else. Caching isn't really required as the bandwidth available has been steadily increasing rapidly while Debian package size has been increasing very slowly. I would consider any sort of proxy, if there's a socks proxy that supports white-listing acceptable domains and apt works well with socks then that would do. Just as long as it's easy to setup and likely to be secure. I have some virtual servers that don't need Internet access for any purpose other than updating Debian packages and which run some PHP code and other things that tends to call out to the Internet if permitted. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

talk about hyper-threading
by Russell Coker 21 Mar '17

21 Mar '17

After a conversation at the beginners meeting I think it would be good to have a talk about hyper-threading and other features of modern CPUs. Would anyone like to give such a talk? It doesn't require detailed knowledge, just a good general knowledge about PC architecture and a little bit of research. It would be a beginner to intermediate talk. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
