quite right, sorry

That's quite all right.

I wasn't interested in the giveaway since I already own a copy and I'm more than happy to let the dev keep my money. However, I have since entered it using your link now that I know you'll get an additional three cracks at winning it. I'm always happy to help a fellow DC member whenever I can.

302  Main Area and Open Discussion / Non-Windows Software / The future of networking - resources for: SDN, OpenFlow and Mininet on: July 10, 2014, 01:44:13 PM
The notion of virtualization has been with us for a long time now. Virtual machines have liberated computing environments from their underlying hardware - with obvious benefits realized industry-wide.

Now that same virtualization model and discipline is finally coming to our network infrastructure with the advent of SDN (software defined networking) and OpenFlow.

If you're going to be working as a network professional in the near future, an understanding of network virtualization will be as much an essential skill for an IT professional as an understanding of machine virtualization is today. So now is the time to start getting up to speed. mrgreen

The following Stamford seminar lecture by Scott Shenker gives an excellent overview of what SDN is, where it came from, and where it's going. Scott discusses the key players, the ideas behind SDN, its architecture, mistakes made along the way, lessons learned, and the design changes and conclusions that have since been drawn. At a little over an hour, this is one of the single best high-level introductions to this initiative, presented by somebody who is directly involved in bringing it to market. Although moderately technical in a few places, it's still very understandable for anyone who has even a tiny amount of home networking experience. Well worth a view - and highly recommended:

<a href="http://www.youtube.com/watch?v=WabdXYzCAOU" target="_blank">http://www.youtube.com/watch?v=WabdXYzCAOU</a>

If a Stamford lecture is a little too formal for your taste (or you only have 25 or so minutes to spare) Eli the Computer Guy has a nice funky down-home introduction you may prefer to watch instead:

<a href="http://www.youtube.com/watch?v=2BJyIIIYU8E" target="_blank">http://www.youtube.com/watch?v=2BJyIIIYU8E</a>

Either presentation is good. Watching both, however, will definitely give you everything you’ll need to be aware of when it comes to SDN.

***

Once you've got some SDN/OpenFlow basics under your belt you'll probably be anxious to put some of it to use - or at least play with it in a lab setting. But switches and networking hardware are awfully expensive, right? Well...luckily, there is a free virtual lab environment available for download called Mininet.

From the website:

Quote
Mininet creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds, with a single command...

Because you can easily interact with your network using the Mininet CLI (and API), customize it, share it with others, or deploy it on real hardware, Mininet is useful for development, teaching, and research.

Mininet is also a great way to develop, share, and experiment with OpenFlow and Software-Defined Networking systems.

Full information, documentation, and instructional videos are available at the Mininet website. Mininet can be run on any operating system in Virtualbox or under Linux.

Want to see it in action? Watch a quick introductory video to Mininet below:

<a href="http://www.youtube.com/watch?v=jmlgXaocwiE" target="_blank">http://www.youtube.com/watch?v=jmlgXaocwiE</a>

People with previous experience with the "terminal mode" found on virtually every professional router (Cisco, HP, etc.) should feel right at home in fairly short order.

SDN! Cool tool. VERY cool! Thmbsup

AFAIK If it's an OEM copy (as opposed to Retail) the answer is no.

Officially, you'd need to install Windows 8 first - then it's highly recommended you install all the available updates for Windows 8 - and then download and install the free upgrade via the Windows Store to bring it up to 8.1. 'Official' process is documented here.

[attach]

Unlike previous versions of Windows, the Windows 8.1 upgrade (from Win8) is only available through the Windows Store. If you don't see it in the store, look here for possible issues with your copy of Win 8. Note: the rules can change depending upon how you licensed it. (Leave it to Microsoft to have such a muddy licensing model.)


However, the official process may not be the best for you. See following post by 4wd for better info...

And it's especially harmful when such posts drown out the conversations that otherwise could be taking place.

@M - Not that I'm disagreeing...but exactly which conversations are those that "could be taking place" that are being crowded out?

From what I've seemed to notice, about the only time an active and robust discussion starts taking place around here is when some legal or political consideration becomes part of the dialog. Which makes sense since you can only say so much amount about a tech topic before it's either exhausted or you start splitting hairs over details or arguing over brands. huh

Have you been getting complaints? huh

The european robin will hang out if you're doing any gardening or pretty much up to anything outside. I've fond memories of messing around in the garden as a kid while my dad did the serious gardening and a robin hanging out nearby with it's head cocked waiting for a worm to appear.
But I've never seen or heard of one trying to teach someone how to catch a worm Kiss

My GF has a brown-headed cowbird that recognizes and hangs with her any time she's messing with the garden, running the lawnmower, or doing stuff outside that stirs up bugs. It will even stand right next to her digging hand (she's actually had to gently shoo it aside or shrug it off her shoulder a few times) when she's weeding or planting in the two raised-beds we have out in back.  

Now that it's figured out she lives inside the house, it goes to the den window and pecks and chatters until she comes out if it thinks she's been absent for too long.

They look like this in case anybody isn't familiar with the species:

Having gone through several iphones between myself, my wife, and my son... I haven't had a reason to replace the battery in any of them, unlike my other phones.  So there is that...

My experience is you get about 3 years out of them under fairly heavy use (at least the 3 & 4s) before the battery starts to have trouble holding a charge. And though I can't speak for everyone, I have yet to get through a full and busy workday without needing to plug my iPhone in sometime in the course of the day. And that's even when it's brand new. But this is probably another one of those YMMV situations.

My GF handles it with her usual "don't screw with me" approach. She refuses to service any of her consumer-level technology. The minute her iPhone starts acting up, she trades it in for a new one. Her feeling is a smartphone is too important a factor in her daily routine to bother fooling around with an unreliable unit.

(Note: as an iPhone user I land somewhere between The Hacker and the Whiner in the spectrum of iPhone owners.)

but the body of writing from these guys is pretty clear,

Excellent point. Thmbsup

We have library shelves of original writing, and large collections of personal letters, from several of these gentlemen. So it's not as if much imagination or scholarly debate is needed to grasp where they were coming from.
310  Main Area and Open Discussion / Living Room / Re: Interesting "stuff" on: July 08, 2014, 11:44:08 AM

Ahaha! Not being particularly interested in iphones, I had not realised that they were effectively unserviceable.

Is that really true?     :tellme

Judge for yourself. Not unserviceable per se. But what a PITA! And needing a proprietary (i.e. TS1-Pentalobe) screwdriver to open some models...seriously?  huh undecided

(Note: the iP4s are considerably easier to work on than the 3 series was.)

I could almost completely assemble a small server in the same amount of time - and only require a single standard #2 Phillips screwdriver to do it. Cool

312  DonationCoder.com Software / Post New Requests Here / Re: Recursively replace characters in all file and folder names Sharepoint restrict on: July 08, 2014, 05:39:16 AM
I was thinking through the logic on the program and wondered what would happen if two different people made different modifications to the same file and then BTsync got ahold of them both.

Whatever rules you set up for the sync priority would apply. Usually the last time/date modified prevails by default. Otherwise it would be whichever source folder was given priority if both copies were modified since the last sync.

If multiple users updating the "same" file in two different locations becomes a concern, the only real way to deal with that problem is to go with a version control (i.e. Git et al.) approach. If you were to go that route, a separate sync wouldn't be necessary because the VC software would handle replication and synchronization automatically. With version control all your users would effectively be working off the same copy of the file.

It would, however, create some additional steps for the users when accessing or writing a file. And using version control is something many people have trouble getting their head around. So unless the scenario you described is actually occurring, it's probably not wise to employ VC.

I think it's probably more along the lines of being addicted to power, and surveillance just being a tool of power.

And then a little splash of voyeurism to boot! smiley

Or perhaps you have quoted someone addicted to forum spamming, who had nothing of real value to add to this conversation. Wink

The thing I really find amazing about the Declaration of Independence is how it still resonates today.

The language in that document is a masterpiece of writing style. And the topics it discusses are still as important today as they were back then.

Like I said, it's a good read. smiley
316  Main Area and Open Discussion / Living Room / Re: The Declaration of Independance- some scholars say we've been reading it wrong. on: July 06, 2014, 12:32:22 PM
Tinfoil hats, but its straight out of 1984. Make a little tweak to history, and suddenly the implications mean that you can do this much more that previously wasn't allowed.

+1 it being Tinfoil Hat.

It wouldn't fly here. Which is why any attempt at a power grab goes out of its way to avoid any mention of the Constitution or similar documents. All such power grabs (to date) have been justified using 'technical' legal arguments or very narrow and "nuanced" interpretations of provisions in the US Code.

The absolute last thing any of the endorsers of our current 'security' rules want to raise is a constitutional debate on the absolute legality of such measures. Because that is an argument they cannot win, no matter how hard they try to twist the Constitution to allow what they're doing.

And furthermore, they know it - as does everyone else. Cool

317  Main Area and Open Discussion / Living Room / Re: The Declaration of Independance- some scholars say we've been reading it wrong. on: July 06, 2014, 12:20:15 PM
It's just the old declaration of war that lead to the founding of the US. Nothing more, nothing less.

On closer inspection, however, it looks like just that -- a cool idea that's too tempting to pass up, even if it doesn't amount to anything.

Yeah...I had a "Bircher" neighbor (his characterization, not mine) that could go on and on about that one. He had a bunch of other "proof" things aren't all that they seem to be with the Declaration or Constitution. Or the Bible either for that matter. Too bad he passed away before the National Treasure movies came out. He would have loved those.

And since we're on the subject, I can't wait from someone to rediscover and reopen the "unalienable" vs "inalienable rights" debate.

Why did Jefferson say "inalienable" whereas others referred to these rights as "unalienable?"

This one comes up every ten or so years in conspiracy and self-taught 'expert' historical 'research' circles.

Those who have done genuine research have long ago concluded that the two spellings were commonplace and interchangeable during the times in question, with writers of the period often switching arbitrarily between the two. Sometimes within the same document or letter.

That doesn't stop some people from reading a whole bit of drama into it despite the overwhelming evidence that clearly establishes either spelling meant the same thing to the framers of the Declaration and Constitution - and that "correct" American-English spelling and punctuation was still very far from being standardized in the 1700s.

It wasn't until well after Webster that word spellings finally started to settle down in the late 1800s. And most scholars of the American language will agree that punctuation usage varied widely until the advent of The Chicago Manual of Style was published in 1906.

The Founding Fathers probably wouldn't have been overly concerned about something that tiny. They would have had sufficient faith in each other and the citizenry to understand the intent behind the document and interpret it in that light.

But they weren't actively seeking ways to get around it like later manifestations of the US government apparently are. undecided

The first few generations of machine life will be just as bad, but once they start to reliably exceed human intelligence they may very well see right through the flaws in our society and proceed to fix it for us. Over time they will lose their incentive to care for the remaining human beings- we'd be dumb and inefficient compared to them...

Wish I had your faith in the potential of machine intelligence. Grin
