Peer to peer live streaming the next battlefield

From Torrentfreak

So as we near the 10th anniversary of BitTorrent its inventor Bram Cohen is finalizing a new protocol, this time aimed at P2P-live streaming. Although P2P-live streaming is not something new per se, Cohen thinks that his implementation will set itself apart from competitors with both its efficiency and extremely low latency.

“Doing live properly is a hard problem, and while I could have a working thing relatively quickly, I’m doing everything the ‘right’ way,” Bram Cohen told TorrentFreak last year when he announced his plans. He further explained that the BitTorrent protocol had to be redone to make it compatible with live streams, “including ditching TCP and using congestion control algorithms different from the ones we’ve made for UTP”

In the months that followed Cohen figured out most of this complex puzzle and the technology is now mature enough to show to the public.

The demo he shows is, well…ummm… underwhelming to say the least. But to be fair if 10 years ago someone said look this is BitTorrent watching it go. You’d also be scratching your head thinking is that all?

There’s no doubt streaming is due a massive. A lot of the rights owners think they can beat P2P downloads with the experience of streaming. They might even be right.

Streaming is certainly the next battlefield. Theres already some high profile projects in this area including P2PNext, but anything remotely like Bittorrent for P2P streaming could be huge. Talking to some of the engineers at work in BBC R&D, anything which can even the field between the costs per person of traditional broadcast and ip delivery could be truly paradigm shaping.

Is this it? I don’t think so, at least not yet.

VPN tunnel your way to safe ground with Hamachi

Hamachi on windows

What is Hamachi?

Hamachi is a UDP-based virtual private networking system. Its peers utilize the help of a 3rd node called mediation server to locate each other and to boot strap the connection between themselves. The connection itself is direct and once it's established no traffic flows through our servers.

Hamachi is not just truly peer-to-peer, it is verifiably secure peer-to-peer.

Believe it or not, but we are able to successfully mediate p2p connections in roughly 97% of all cases we dealt with so far (few tens of thousands as of early March). This includes peers sitting behind different firewalls and/or broadband routers (aka NAT devices).

Oh my goodness, if you have not tried out Hamachi and want access to your home network from elsewhere. You need to try it out! I heard it about it ages ago but dismissed it because I didnt really see the need. Well that was before I learned about how insecure Wifi can be. So during hearing this week's Security Now podcast

I spent a hour checking out Hamachi. At the moment it runs on Windows and Linux but after verison 1.0 (there currently 0.99) it will be developed for the Mac too. I dont see why you cant run the Linux version on a Mac command line but I'm sure there is a reason. So anyhow once you got it installed you can follow the Wizard which is a little too simple but good for those not deeply into networking, its easy to escape at anytime.
Once your setup its just a matter of making a new network or joining another one. You can easily make one and the the security is then all hanged off your stupidly impossible to crack password. GRC recommends some 63 character password string which can be generated here at the High security password generator. I actually went for a stupid 96 ASCII character password with all types of characters. I'll switch it down to 63 because Hamachi uses a 256bit AES crypto for authentication. After setting the password and name of the network you can go to another machine and do the same but this time hit join and enter the same details.

Before you know it your on a new type of network. Actually a 5.x.x.x IP address. I didnt even know you could actually have one of those for a network, I always thought 10.x.x.x was the lowest things went. Ok so once you got two machines on the same p2p network your away. I was able to tunnel out of my work network and on my own computer at home and launch VNC and access the net and machines attached to the same physical network. Everything is accessable and the speed is amazing. Oh yeah by the way, I only had to open one port on Smoothwall for it to work, most firewalls and NAT environments can be traversed without opening ports and port forwarding according to the Hamachi creators. I did nothing to the work network, like Skype it just worked. Crazy but true. I also tried using Hamachi with some of the sniffing tools out there and glad to say it works perfectly. All traffic is secured and even insecure connections like POP3 retrivial can not be discovered as it all looks like normal web traffic. Honestly I cant wait for version 1.0 of Hamachi. Its solved so many of my problems its untrue.

Listening to the next net generation

The teen demographic uses the Web constantly and in very sophisticated ways. They don't want to pay for very much, but if you can find something they will pay for (like ring tones), they tend to spend a lot. Safa Rashtchy, managing director of Piper Jaffray, interviewed five seventeen- and eighteen-year-olds about their relationships with technology.

Oh my goodness you have to hear the end of this podcast enclosure, what Teens want – starts at 15:20 mins and lasts about 8mins. Cant wait to hear the whole thing on IT Conversations really soon.

Generally the thoughts is free is good and there's some thoughts about spyware and advertising. Someone did mention paying artist of the music via iTunes but generally there was no thoughts beyond free download. Although you can listen to it and shake your head in shame, I dont. I use to think exactly the same way. Now at least I'm a little more aware of the issues and the cultural shifts. I'm sure the teenagers on stage will alter there views a little over time. But honestly its refreshing to hear the younger generation talk frankly about there habits.

Tape it off the Internet, no really do!

Thanks to a comment by Duncan in my kill TV post a while ago, I've now checked out Tape it off the internet.com. Although its not actually a web 2.0 application or social tool yet. Its got a lot of potential as idea at least.

They seem to have a lot of the simple things right, for example there is a post about why recommendations could be important when you drop off the schedule. There right, when you drop off, you end up relying much more on friends recommendations and what people and things around you say. So for example me and sarah have become big fans of Firefly and Serenity, browncoats some would say. The reason I engaged with Firefly and the movie serenity was a couple of things. My friend doug, a lot of blogs about the treatment Firefly got from Fox and what tipped the balance a Wired article. I was recommended Lost by my buddy Waheed and Prision Break from Tom but another way I gage interesting shows is by torrents which have lots of downloaders times by the time it was published. Some Torrent sites make this easy to sort by, others dont. It would be nice to have a webapi for these things sometimes.

But back to tape it off the internet, another thing which made me shake my head in agreement is the friends x episode tracker. Its best explained in the post.

Let us take the problem outlined below, that of different friends of yours not all being on the same episode of a show, making conversation about said show… delicate to say the least, lest you drop a clanger of a spoiler.

Seriously this happens all the time, i usually have to ask what episode someone is on before talking about it. Lost is a nightmare right now because a ton of people are on the UK series which I believe is coming to the end of series 1 soon. A couple of friends have seen the whole series 1 but not started on 2, and then about 3 people I know are fully up with ep5 of series 2.

So guys behind the idea, when's the vaporware going into Permanent BETA with a Open API, tagging and tons of Ajax? hehe…

Should we kill TV but keep the shows?

So I was almost done with my RSS aggregator for the night when I read Jon's entry titled I Watch Shows, Not Tv. As I was reading through, I was in total agreement with Jon. Some choice quotes which made me laugh.

The medium had become totally uninteresting to me. Reality Tv was everywhere, sitcoms sucked, and ads were worse.

Enter Bittorrent, Hd rips, and RSS. Ever since I set up my system, not only do I watched more shows, but I watch a LOT of shows. I probably have at least 10 shows I watch weekly without missing a beat. But not only do I get to watch them at my own convenience

The only television I watch is the television I watch. That makes sense, I swear. When I’m done with a show. That’s it. I don’t flip to the next channel to see what else is on. I finish and move onto another project. Just sitting in front of your Tv leads to watching Hugh Hefner’s Whores jumping around pretending they have enough content to constitute television. I’d rather sit down catch 42 minutes of Lost or 28 minutes of Curb and be happy.

Totally! I have a very simlar setup to Jon, xbox media centre and all. And he's so right, me and Sarah watch a lot of shows including Lost series 2, Prison Break, Daily Show, etc, etc. When I was in hospital recently, the lovely nurse asked if I wanted the TV on, and without thinking I replied “No, I don't watch TV.” Bang just like that without thinking about it, then I realised what I just said. Honestly me and Sarah turn on the TV for the BBC news 10min update at about 8am in the morning then we turn off and listen to the slashdot review podcast if there is time. When we get back in the evening, we may turn on Channel4 news for 1 hour and maybe once in a while leave it on and watch grand designs or something like that afterwards. But usually we turn off have dinner together and maybe put on a show or listen to a podcast while we catch up with news, emails, etc. Even with the daily show on more4 every day now, Sarah's not interested because shes use to timeshifting it. She does'nt like the idea of turning on the daily show at 8:30pm every day and sitting in front of the TV.
Hey and why would we? With TV RSS we can store them and watch a whole load together with friends on a weekend or watch it the week after if we choose to.

Moving on, I read the related link and found the tons of comments mainly in agreement.

But I say all this and I know something doesnt quite fit.
I've heard about studies in the BBC which went down this route of the show being more important that the channel and TV its self. But these studies say when that is the case, people look for brands they can trust. Channels are a odd thing, if you live in the UK, you may think of BBC one as generally massmarket but higher class than ITV (my view not the BBC's view), BBC two more documentary's and nature programmes but still some comedies and mass market contnet. BBC Three, for people 35 and younger, somewhat like BBC two but with lots of comedies and reality tv. BBC four, highbrow documentary's and some news.
People use these types of thoughts to decide what channel they should wait on or check out. Remove the channel and people try and cling on to many other things like brand to tell them more about the programmes and there expected audience.

So although I'm with you Jon, I need to err on the side of caution because people need to make money without killing the distribution method (as they do now). Itunes video is a good move away from tv and towards shows and programmes.

To the person(s) who put prisonbreak.s1.ep1 inside of lost.s2.ep1

To the person(s) who put prison break.season 1.ep 1 inside of the lost season 2.ep1 torrent today and yesterday. I was, (lets say it gently) slightly pissed off. This is the kind of thing you see on old school p2p networks like Kazaa not on Bit Torrent.

This is the first time I've ever downloaded something which was labled something else on bit torrent, maybe this is a growing trend? Has anyone else experienced this? I noticed the torrent in question has been removed from the piratebay. But I had already almost uploaded 3 times the contents of the torrent without knowing by the time I had got home today. So sorry to everyone else who was also duked. But to add aditional insult, I also downloaded Prison Break ep1 too, so I ended up with two of the same file. You can tell I was very very pissed off. At least Tom's recommendation for Prison break was a good enough choice to finally calm me down. Certainly no Oz, but interesting none the less. I'm just waiting for Fox to ruin it with some 24 type government propaganda.
