IPv6 celebrates its 20th birthday by reaching 10 percent deployment

All I want for my birthday is a new IP header.

Twenty years ago this month, RFC 1883 was published: Internet Protocol, Version 6 (IPv6) Specification. So what's an Internet Protocol, and what's wrong with the previous five versions? And if version 6 is so great, why has it only been adopted by half a percent of the Internet's users each year over the past two decades?

10 percent!

First the good news. According to Google's statistics, on December 26, the world reached 9.98 percent IPv6 deployment, up from just under 6 percent a year earlier. Google measures IPv6 deployment by having a small fraction of their users execute a Javascript program that tests whether the computer in question can load URLs over IPv6. During weekends, a tenth of Google's users are able to do this, but during weekdays it's less than 8 percent. Apparently more people have IPv6 available at home than at work.

Google also keeps a map of the world with IPv6 deployment numbers per country, handily color-coded for our convenience. More and more countries are turning green, with the US at nearly 25 percent IPv6, and Belgium still leading the world at almost 43 percent. Many other countries in Europe and Latin America and even Canada have turned green in the past year or two, but a lot of others are still stubbornly staying white, with IPv6 deployment figures well below one percent. Some, including China and many African nations, are even turning red or orange, indicating that IPv6 users in those countries experience significantly worse performance than IPv4 users.

Company 3D prints ceramics that can withstand 1700ºC temps

Combining several technologies into a process that makes very robust materials.

(credit: HRL Laboratories, LLC)

Ceramics have many useful properties: they can be extremely durable, and hold up to very high temperatures. Unfortunately simple flaws in the material can leave the door open for catastrophic failures, making manufacturing, especially of complex shapes, challenging.

Now, a team at a company called HRL Laboratories has described a method of 3D printing ceramics. The work, which combines a number of techniques that have already been in use, can create complicated structures that are very robust and able to withstand temperatures of up to 1,700 degrees Celsius.

The foundation of the work actually dates back to the 1960s. That's when researchers developed what are called polymer-derived ceramics. These are standard polymers made of chemicals that incorporate some of the materials that are typically used to make ceramic (such as silicon and nitrogen). Once the polymer is made in the desired shape, it can be heated, which causes it to undergo chemical reactions that decompose the organic portion of the polymer. Those escape as methane or carbon dioxide, leaving behind a ceramic composed of silicon, carbon, and nitrogen.

Ars Deathwatch 2016: Companies and tech whose time may have come

Ars picks the losers of next year who are out of cash, relevance, time, or control.

The coming of the new year gives us an opportunity to both look back wistfully and look forward with hope. It also offers a chance to look back with anger and toward the new year with a sense of cynicism and schadenfreude. So, in the interest of curdling your eggnog a bit, we're dusting off Ars' tech company "Deathwatch" list to see which companies we've tracked in the past have managed to survive, which have slipped into various levels of oblivion, and which companies need to be added to the stack to replace those that have either emerged victorious or have fallen irrevocably into corporate limbo.

First, a clarification of our criteria for what places a company on Deathwatch. To be considered, companies need to have experienced at least one of the following issues:

  • An extended period of lost market share in their particular category
  • An extended period of financial losses or a pattern of annual losses
  • Serious management problems that raise questions about the business model or long-term strategy of the company

The Deathwatch took a holiday last New Year's, but our 2014 picks proved to be good for another 12 months of pain: RadioShack, BlackBerry, Zynga, HTC, and AMD. RadioShack, our most sickly suspect, restructured and then sold some of its stores to Sprint, closing the rest. While it still exists as a brand in some locations, the company has essentially ceased to exist. We rule that RadioShack has earned a toe-tag, while the others…well, they're largely in the same delicate condition they were in when we last did this list.

Bayern: Landtagsabgeordneter nennt 50 MBit/s Steinzeit

The McLaren 650S Spider becomes your favorite car—and hits 100mph—in 6.3 seconds

A supercar so clever it should have a PhD.

We test the McLaren 650S Spider. Cinematography by Ivan Flores, editing by Jennifer Hahn. (video link)

OK, we'll admit it—there was a lot of excitement in the office leading up to our time with the McLaren 650S Spider. And why not? This is a proper carbon fiber supercar, built in the same factory as one of the most successful and storied Formula 1 teams. It's from the same company that built the legendary McLaren F1, a 240mph three-seater that to many—including yours truly—remains the greatest car ever to turn a wheel. We were the first publication to get any time with McLaren's latest press car, fresh off a boat from the UK with a mere 350 miles on the digital odometer. The following few days were extremely memorable, and the Volcano Red convertible earned its position as our favorite car of 2015.

McLaren has been building road cars for more than 20 years now. We shan't bore you too much with talk of the F1, save to say it was the first completely carbon fiber road car, and it came with a fantastic 6L BMW V12 engine, three seats, and a top speed that wasn't equalled until the Bugatti Veyron appeared with another 400hp. Sadly, just over 100 were ever built (the plan was to make 300), and today you'll need quite a lot of money to buy one. Recently, one sold for $12 million—not bad for a car that was selling for less than list price in the late 1990s.

Secret Lovers: Public and Private Torrent Sites

Which is best – public torrent sites like KickassTorrents and Pirate Bay or private torrent sites like What.cd and PassThePopcorn? While that’s an interesting and everlasting debate, the big secret is out: public and private sites secretly love and need each other.

Source: TorrentFreak, for the latest info on copyright, file-sharing, torrent sites and ANONYMOUS VPN services.

loveThe endlessly entertaining /r/trackers and /r/torrents subs of Reddit are inhabited by a broad range of BitTorrent users, from the just starting out to the seriously experienced. As a result discussions range from the very basic to the fairly complex which makes them great environments for those of all skill levels.

The million dollar question

Pretty regularly the topic lands on the differences between public and private torrent sites and the inevitable million dollar question: Which is the best?

As someone who has seen this conversation play out dozens of times before it’s no surprise what happens next. Users of each type of site regularly batten down the hatches and go head to head with their perceived rivals in a battle to be won at all costs.

But the truth is this: public and private sites and their users might sometimes pretend to hate or have disrespect for each other, but the existence of both amounts to a match made in heaven. They squabble and bicker in public, but quietly they crave each other’s attention. In fact, these secret lovers can barely stand to be apart.

‘Elite’ torrent users didn’t appear by magic

Many (not all) private trackers work on the assumption that their users are among the elite. These individuals have perfectly honed systems, underpinned by the finest torrent client setups ever seen. Their sharing manners are impeccable and their access to content unprecedented.

Surprise!! These users didn’t simply appear out of thin air.

The majority of today’s “elite” users will have started out on the public torrent scene where they picked up knowledge and developed their skills over time, possibly several years. Like many they will have heard of the private tracker streets paved with gold and aspired to tread them one day.

Eventually, when luck, judgment and an existing member with invites all collided, Joe Public will have entered the Promised Land. The chances are he will have been impressed by what he found. Many private trackers display exceptional attention to detail, are meticulous in their presentation, and have great communities to boot.

But make no mistake, without his training on the public scene Mr Public would not have lasted long on a private tracker. Thankfully he already knew many if not all of the basics and while private site staff might not like the public scene too much, they are grateful to it for educating their new recruit. Rarely will they admit it, however.

Join us – if you can (but it won’t be easy)

Perhaps one of the most interesting things about the private / public rivalry is how the former absolutely needs the latter to boost its ranks. Many private tracker users/staffers hang out on /r/trackers and /r/torrents and many are happy to answer questions. Need movies faster? Better quality music? Cure for arthritis? Join a private tracker!

However, as many advice recipients discover, that’s often easier said than done. Most private sites have strict limits on the number of members allowed in and the majority require users to be invited. Several demand that prospective members sit an entrance exam or interview to get in. It can be a real hassle.

No room at the inn :(

That said, limited availability of member slots exists for a number of reasons, not least technical limitations and other practicalities of running a relatively small site.

While this is a nuisance for those looking to get in, this is a real plus for private trackers. Not only do they have the luxury of picking and choosing new entrants, they also maintain the exclusivity that makes them so desirable to join in the first place. But just as new members trickle in, other things flood right out.

Thanks for the content, private trackers

For many years the so-called warez scene was the source of much of the content available online today. Things are changing in a very big way though and P2P distribution is now the uncrowned king.

Recently a flood of DVD screeners began to hit the Internet yet none of them came from a traditional ‘Scene’ source. In fact (and as far as the masses are concerned) most of them first appeared for the early enjoyment of the lucky individuals inhabiting private trackers. Eventually nearly all of them spread to public sites though. And users of those sites are grateful, even if they don’t mention it.

They should just get along

The ubiquitous nature of public sites has created a wealth of interest in file-sharing that private sites could never have managed on their own. Both have benefited as a result and it’s hard to escape that.

Also, most private torrent site users were doing their thing in public at one stage and when it comes to swelling their ranks, footfall to private sites is provided by the public. ‘Elite’ users don’t just appear out of thin air.

And, when Joe Public finds he can’t or refuses to keep up with the often stringent rules and requirements of private trackers, there needs to be a safety net or he could disappear from the P2P sharing scene entirely. Where does he go? Back to public torrent sites, of course.

Finally, for those who like to measure the quality of public and private sites by comparing YIFY rips with those more exclusively available – two words:

Gateway. Drug.

Excited new recruits coming up……and the secret love affair continues.

Top 10 Most Popular Torrent Sites of 2016

Posting a list of the world’s most-visited torrent sites has been a long-standing tradition at TF, which we continue today. At the start of 2016 KickassTorrents is pulling in most traffic followed by The Pirate Bay. A lot of things have happened over the past year, with some torrent sites disappearing from the scene and others taking their place.

Source: TorrentFreak, for the latest info on copyright, file-sharing, torrent sites and ANONYMOUS VPN services.

2016Most file-sharers are creatures of habit, but when their favorite site disappears they gladly hop over to the next one.

This is also reflected in our annual top 10 which sees the usual names on top but also features some dubious newcomers.

One of the major changes came with the hostile takeover of the popular TV-torrent site EZTV. This prompted the popular TV-torrent distribution group to shut down last May. Another group took over the popular brand and continued with their own ‘unofficial’ EZTV releases. We therefore marked the site as a newcomer.

Something similar happened to YIFY’s YTS website, when the Australian admin ran into legal trouble. The official YTS website shut down but it was quickly replaced by the “unofficial” YTS.ag, which gathered a large user-base over the past two months.

Apparently, most torrent users are happy as long as they can get their fix, no matter what the source is.

KickassTorrents (KAT) remains the most visited torrent site and continues to grow. The Pirate Bay is listed in second place and made a strong comeback after nearly two months of downtime spanning the turn of the year. Since the site has been operating from several domain names until a few days ago, we chose not to list an Alexa rank.

Finally, it’s worth noting that Rutracker would have made it into the top five based on the number of visitors. However, we choose to only include English language content sites.

Below is the full list of the top 10 most-visited torrent sites at the start of the new year. The list is based on various traffic reports and we display the Alexa rank for each. In addition, we include last year’s ranking for each of the 10 sites.

1. KickassTorrents

KickassTorrents was founded in 2009 and surpassed The Pirate Bay in traffic last year. Battling various censorship efforts the site has burned through a few different domain names over the years. Most recently it switched to a Costa Rican .cr domain after it lost its Somalian .so address.

Alexa Rank: 85 / Last year #1

2. The Pirate Bay

The Pirate Bay is one of the main piracy icons. The torrent site wasn’t online at the beginning of 2015 and had to deal with a staff revolt. However, it quickly regained millions of users after a successful comeback operating from a hydra of domain names until last week.

Alexa Rank: NA / Compete Rank: NA / Last year #4

3. ExtraTorrent

ExtraTorrent continues to gain more traffic and has become one of the most active torrent communities. The site is also the home of the popular ETTV and ETRG release groups.

Alexa Rank: 342 / Last year #3

4. Torrentz

Torrentz has been the leading BitTorrent meta-search engine for many years. Unlike the other sites featured in the list Torrentz does not host any torrent files or magnet links, but redirects visitors to other places on the web. The site uses several domain names with .eu being the most popular.

Alexa Rank: 351 / Last year #3

5. RARBG

RARBG, which started out as a Bulgarian tracker, was last year’s newcomer and continues to rake in more visitors. The site was blocked by UK ISPs last year, which put it on par with most other sites in the top 10.

Alexa Rank: 1,101 / Last year #7

6. 1337x

1337x has traditionally been a community driven torrent site but several weeks ago most of the admins and moderators abandoned ship over security concerns. The coming year it will become clear whether 1337x can keep its popular status.

Alexa Rank: 1,249 / Last year #9

7. EZTV.ag

TV-torrent distribution group EZTV shut down earlier this year after a hostile takeover. The site continued to operate under new ownership and releases its own torrents now. In solidarity with the original owners several large torrent sites have banned these ‘new’ releases from their sites.

Alexa Rank: 1,373 / Last year #NA

8. TorrentHound

TorrentHound has been around since the last decade but is a newcomer in the top 10. It has also been on the radar of copyright holders this year. The torrent site is blocked in several countries and was reported as a piracy haven to the U.S. government, alongside many other sites in this list.

Alexa Rank: 2,239 / Last year #NA

5. YTS.ag

YTS.ag has nothing to do with the original YTS or YIFY group, but aims to take its place. As with the new EZTV, several large torrent sites are not allowing the group to use the YIFY or YTS brands on their sites.

Alexa Rank: 740 / Compete Rank: 4,271 / Last year #NA

10. TorrentDownloads

TorrentDownloads has been around for several years. The torrent site regained a spot in the top 10 this year after it was featured for the last time in 2011. It’s a no-nonsense index that provides torrents to millions of users each month.

Alexa Rank: 2,969 / Last year #NA

Disclaimer: Yes, we know that Alexa isn’t perfect and that Compete has plenty of flaws, but when combined both do a pretty good job at comparing sites that operate in a similar niche.
