Get off and get stuffed with this vibrator that orders you a pizza when you’re done

Forget friends with benefits — now, there’s GrubHub with advantages.

CamSoda, the adult amusement website, is releasing a vibrator called the RubGrub that orderings the user a large cheese pizza from Domino’s after they orgasm.

Yes, it’s an actual vibrator that is really get you a pizza. The doll has a button that’s similar to the Amazon Dash, which is connected to the user’s phone and is pre-programmed with payment and delivery datum.

After you finish buzzing, only push the button at the base of your RubGrub, and poof! A cheesy post-climax delight is headed to your doorway.

Their slogan is “Get off, and get stuffed! ” But is a giant pizza really what you crave most after a little quality day with a sex doll?

In a statement, Daryn Parker, CamSoda’s VP, said the answer is yes: “Masturbation, while ultimately enjoyable, can be a strenuous physical activity during which private individuals exerts a lot of energy and ignites many calories. Inevitably, once a person has climaxed, they seem lethargic and hungry.”

Hmm. Well, either way, it’s an enjoyable notion. And it’s not the first time CamSoda has had a little fun with a sexuality toy. The company is also behind Bitcast, the interactive sexuality toys that vibrate based on how much the value of various cryptocurrencies rise and fall.

But if you’re not into needlessly complex masturbation habits, or if the very fact of knowing a fresh hot pizza “re on their way” gets you off, CamSoda’s RubGrub can be yours for $19.95. The company also plans to expand its cuisine selection to include Mexican and Chinese take-out too.

The future is now, folks, and it is…delicious.

The number of dogs named ‘Bitcoin’ is, unfortunately, more than zero

Image: Getty Images/ RooM RF

Every day we stray further from God’s light. Case in level: it appears that, on this cursed Earth, there are more than zero dogs named Bitcoin.

Yes, for some reason, real humen have looked into a dog’s beautiful, loving eyes and guessed, “This dog should be named Bitcoin.” We don’t know why and we are genuinely can’t stop it — all we can do is let you know and hope that this idea doesn’t become a trend.

Here’s one puppy named Bitcoin, a Maltese puppy who has a very pleasant Instagram presence. Luckily, Bitcoin seems to be interested in cryptocurrency( judging by her captions, anyway ), so perhaps the name is a good fit.

Here she is with a doll shaped like a dollar sign.

On Twitter, there are even more reports of puppies named Bitcoin. One consumer alleges that her grandfather named his new dog Bitcoin, a choice that is confounding but not necessarily surprising considering the current state of the world( shambles ).

Will the epithet spike in popularity as the cryptocurrency epoch rages on?

Another person reported last year that his cousin named a dog “Biggie Bitcoin.” I am not sure this counts, as the dog is likely referred to as “Biggie, ” but it seemed too wild to omit.

If you’re in NYC, though, feel free to retain your moral superiority a little longer — at the least as it relates to puppy epithets. According to the NYC puppy name map — one of the best things to ever be online — there are 0 dogs named Bitcoin currently registered in New York City. Same runs for these other crypto-related terms: Ethereum, Crypto, Litecoin, Dogecoin, and Blockchain. There are a few bird-dogs named Krypto, but we presume this is a Superman reference.

This doesn’t mean there aren’t Bitcoins out there we just aren’t aware of yet. For instance, the Bay Area, home of Silicon Valley, does not have a publicly available bird-dog name database. But for all we are aware, a little Bitcoin is being mined — I entail, adopted — from a shelter right now.

Seems somewhat likely.

I resisted the advocate to get a decent VPN for my Android phone for years. Why bother with an extra app simply to get online , now that internet connects are ubiquitous?

Over time, nonetheless, the scenarios in which I needed a VPN became more common. I needed to check what this or that website was like from another geolocation. Or I needed to test an app that wasn’t available in my country. But what ultimately constructed me cave in was being unable to watch some of my favorite Tv displays while traveling.

A VPN, or virtual private network, renders an additional layer of privacy when connecting to the internet. It’s like employing a private passageway to browse the web, retaining you safe from prying eyes and enabling you to surf as if you two are connecting from a server in a different place. Typically, all you need to do as a user is install the app on your smartphone, start it up, opt a server location, and then you can just continue browsing as usual.

Choosing which VPN provider to go with, nonetheless, is both easy and incredibly difficult. There are hundreds to choose from, but it’s very hard to exam how dependable they are in different scenarios. So below, you’ll find a listing of some VPNs, both free and paid, that are just plain good.

A word of caution: People use VPNs for various purposes, ranging from accessing a video stream to protecting their privacy from an entity that are likely to be monitoring online communications, including oppressive governments. Not every VPN offers the same degree of anonymity and the fine print can be important here; if privacy is important to you, carefully read the privacy policy of each service before “youre using” it.

Various VPNs offer versions of their service for Android machines. Here are the best ones that we’ve tried, in no particular order 😛 TAGEND


Even though it’s not as good as some of the paid options out there, I like Opera’s VPN because it’s free and because it has a big, reliable brand behind it( Opera has been inducing web browsers for two decades ).

And if you simply skimmed over that paragraph above, let me echo the important bit: It’s free. It expenses you nothing to try it out, and with Opera’s reputation, you don’t have to worry about getting your phone infected by malware. The app also offers a building up ad blocker and the ability to determine the security degree of the Wi-Fi network you’re connected to.

Opera won’t give you the amount of versatility you’ll get from paid alternatives, though. There are five virtual places to choose from, and torrenting is not supported.

NordVPN has a somewhat affordable long term payment plan.

NordVPN has a reputation for being amongst the sturdiest, most reliable VPNs out there and my experience have concluded that. Whenever I needed to mimic being in a different geolocation, NordVPN had a server that was fast, and, even more importantly, the server was not on any blacklist. With it, I was able to stream Hulu depicts in several European countries without issues.

NordVPN says it offers over 3,533 servers worldwide. It lets you connect six machines at the same time, and it claims to keep no logs of your activities.

Unlike Opera, NordVPN isn’t free, but here’s the bad news: It’s very, very hard to find a decent VPN that’s free. NordVPN does have some pretty sweet long-term bargains, like a three-year subscription for $99. This might sound like a lot of fund out of the gate, but divide it into monthly installments, and it’s simply $2.75 per month.

The app’s circular UI is a little odd, but after a while you’ll get are applied to it, and you’ll find that it does give you a solid overview of what’s happening. The app’s settings don’t offer a lot but the basics are there: You can set up trusted Wi-Fi networks or let some apps to bypass the VPN altogether.

F-Secure’s paid tiers “re a bit” different to most VPN services. A 49.90 euro ($ 62.44) one-time payment( this boils down to 4.16 euros or $5.21 per month) will get you 12 months of access with the ability to use it on up to three machines at the same time.

Like essentially all VPNs out there, ExpressVPN promises a ton of servers( more than 1,700 ), limitless bandwidth , no regulations, and great accelerates. It likewise openly advertises the fact that it’s based in the British Virgin Islands, which doesn’t have data-retention statutes, entailing the company isn’t required to keep activity or connection logs.

One area where it stands out is the number of available places, a whopping 148 metropolis in 94 countries. It also supports a ton of security standards, including 256 -bit AES encryption.

The starting monthly cost for ExpressVPN is pretty engulf: $12.95 per month. But you can also buy a 15 -month subscription for $99.95, which means you’re actually paying $6.67. Not the cheapest alternative out there, but still OK. And if you’re a cryptocurrency devotee, you’ll like the fact that you can pay that in bitcoins.

Using the app is simple enough: Burn it up and select a locating( you get a recommended place depending on your actual geolocation which should give you good accelerate ), and then surf away.

First things first: TorGuard has no relation to the Tor anonymizing project or the underlying engineering. But it’s still a very versatile VPN for all platforms, including Android, aimed primarily at folks who like to do torrenting without are concerned about getting an unwanted letter in the mail telling them to stop.

The service allegations it has more than 3,000 servers in more than 55 countries, effectively devoting it limitless bandwidth( i.e. you don’t have to worry about too many customers taxing the system at any one time ).

TorGuard is not the most beginner-friendly alternative out there; in fact, the first thing it’ll ask you after you flame it up is to choose between a variety of security protocols that most people don’t know much about. Still, once you’ve clicked on those and connected to a server, you’ll be fine.

The pricing starts at $ 9.99 per month but that can be lower if you pay on a quarterly, semi-annual, annual or a biennial basis. Bitcoin as well as Litecoin are accepted as pay.

TunnelBear’s main selling level is simplicity and ease of use, and it delivers. After downloading the app, all you need to do is create an report( merely your email address and password is necessity ), demonstrate the registration via email, and you’re good to go. The animation of a bear actually tunneling from one place to another is pretty great, too.

The app is free, but it only gets you a monthly 500 MB, which will be enough for a little bit of work but definitely won’t do for video streaming.

Weeks of negative news and commercial setbacks have buffeted digital tokens. Lloyds Banking Group Plc joined a developing number of big credit-card issuers have said they’re halting purchases of cryptocurrencies on their cards, including JPMorgan Chase& Co. and Bank of America Corp. Several quoth risk antipathy and a desire to protect their customers.

SEC Chairman Jay Clayton said he supports efforts to bring clarity to cryptocurrency matters and that existing rules weren’t designed with such trading in mind, according to prepared remarks for a Senate Banking Committee hearing Tuesday on virtual currencies.

Bitcoin’s longest operate of loss since Christmas day has coincided with investors exiting risky assets across the board, with stocks retreating globally. Bitcoin so far has appeared to be struggling to live up to any compared to gold as a storage of value, which is an statement made by some of its supporters. Bullion edged higher as other safe havens — the yen, Swiss franc and bonds — likewise gained.

Meanwhile, North Korea is trying to hack South Korea’s cryptocurrency-related programs to steal digital currencies and has already stolen tens of billions of won worth, Yonhap News reported. And authorities in digital-coin powerhouse South Korea and other countries are weighing increased regulatory scrutiny of the industry, news which helped trigger the ongoing selloff.

Yet some Bitcoin stalwarts remain unconcerned.

The WIRED Guide to Bitcoin

Bitcoin is a digital currency. Like other currencies, you can use it to buy things from shopkeepers that accept it, such as, or, as is more often the example, hold on to it in hopes that it will increase in value. Unlike traditional currencies, which rely on governments and central banks , no single entity controls bitcoin. Rather, it is supervised by a worldwide network of volunteers who maintain computers operating specialized software. As long as people operate bitcoin software, the currency will keep working, because everything needed to keep it operating is stored in a distributed ledger called the blockchain. And even though it’s all digital, bitcoin is scarce.

Its most wild-eyed proponents belief bitcoin’s decentralized, cryptographic approach to currency can yield a host of benefits: restriction central bankers’ ability to damage economies by publishing too much fund; eliminating credit-card fraud; bringing the unbanked mass into the modern economy; devoting people in unstable economies a safe place to park their money; and stimulating it cheap and easy to transfer monies. But bitcoin has yet to realize these goals, and critics argue it is likely to never live up to the hype.

When you mail or receive bitcoin, your bitcoin software, referred to under as a “wallet, ” records the transaction in the blockchain. The blockchain shall be managed by, and distributed across, the roughly 200, 000 computers operating bitcoin software. If someone tries to alter the ledger to make it look like they have more bitcoin than they’re supposed to, the tampering will be apparent because it won’t match the other two copies of the blockchain.

People who devote the computing resources to processing bitcoin transactions are paid in bitcoin, but only if the computers they operate are first to complete complex cryptographic puzzles in a process called “mining.” New bitcoins are created automatically by the software and awarded to the winners of the race to solve these puzzles. As of February 2018, that accolade is 12.5 bitcoins. By design, simply 21 million bitcoins will ever be created. Those who process transactions can also collect costs; the fees are optional and set by the person who initiates a transaction. The larger the cost, the faster the transaction will likely be completed. This system keeps bitcoin scarce while rewarding people for the investment in the infrastructure required to keep a world payment-processing system operating. But the mining process comes with a big catch: It uses a huge amount of electricity.

Adoption of the cryptocurrency has been hobbled by a series of scandals, high-tech heists, and disputes over the software’s intend, all of which represent why financial regulations were created in the first place. The bitcoin community has solved some mind-boggling technological difficulties. But constructing bitcoin a true-life replacement for, or even adjunct to, the global fiscal system involves more than just great tech.

The History of Bitcoin

On Halloween 2008, someone using the name Satoshi Nakamoto mailed an email to a crytography mailing list with a link to an academic paper about peer-to-peer currency. It didn’t make much of a splashing. Nakamoto was unknown in cryptography circles, and other cryptographers had proposed similar schemes before. Two months ago, however, Nakamoto announced the first release of bitcoin software, demonstrating it was more than simply new ideas. Anyone could download the software and start using it. And people did.

In the early days, bitcoin was applied almost exclusively by cryptography geeks. A bitcoin sold for less than a penny. But the idea slowly caught on. Bitcoin emerged in the aftermath of the 2008 financial crisis when some people–especially free-market libertarians–worried the Federal Reserve’s attempts to increase the money supply would lead to runaway inflation.

Nakamoto disappeared from the internet before bitcoin attracted much mainstream attention. He handed control of the project to an early contributor named Gavin Andresen in December 2010 and cease posting to the public bitcoin meeting. To this day, Nakamoto’s identity remains a mystery.

No one knows who the inventor of bitcoin really is. These are a few of the suspects.

The WIRED Guide to the Blockchain

Depending on who you ask, blockchains are either the most important point technological advances since the internet or a solution looking for a problem.

The original blockchain is the decentralized ledger behind the digital currency bitcoin. The ledger consists of linked batches of transactions known as blocks( hence the word blockchain ), and an identical transcript is stored under each of the roughly 200, 000 computers that make up the bitcoin network. Each change to the ledger is cryptographically signed had demonstrated that the person transferring virtual coins is the actual proprietor of those coins. But nobody can spend their coins twice, because once a transaction is recorded in the ledger, every node in the network will know about it.

Who paved the style for blockchains?

DigiCash( 1989)

DigiCash was founded by David Chaum to create a digital-currency system that enabled users to construct untraceable, anonymous transactions. It was perhaps too early for its hour. It went bankrupt in 1998, just as ecommerce was finally taking off.

E-Gold( 1996)

E-gold was a digital currency backed by real gold. The corporation was plagued by legal difficulties, and its founder Douglas Jackson eventually pled guilty to operating an illegal money-transfer service and conspiracy to dedicate fund laundering.

B-Money and Bit-Gold( 1998)

Cryptographers Wei Dai( B-money) and Nick Szabo( Bit-gold) each proposed separate but similar decentralized currency systems with a limited furnish of digital money issued to people who dedicated computing resources.

Ripple Pay( 2004)

Now a cryptocurrency, Ripple started out as a system for exchanging digital IOUs between trusted parties.

Reusable Proofs of Work( RPOW)( 2004)

RPOW was a prototype of a system for issuing tokens that could be traded with others in exchange for calculating intensive run. It was inspired in part by Bit-gold and created by bitcoin’s second user, Hal Finney.

The idea is to both keep track of how each unit of the virtual currency is expended and prevent unauthorized changes to the ledger. The upshot: No bitcoin user has to trust anyone else, because no one can defraud the system.

Other digital currencies have imitated this basic mind, often trying to solve perceived problems with bitcoin by constructing new cryptocurrencies on new blockchains. But advocates have confiscated on the relevant recommendations of a decentralized, cryptographically secure database for uses beyond currency. Its biggest boosters believe blockchains is not able to supplant central banks but usher in a new era of on-line service outside the control of internet monsters like Facebook and Google. These new-age apps would be impossible to censor, proponents say, and would be more answerable to users.

Several corporations are already taking advantage of the Ethereum platform, initially built for a virtual currency. The startup Storj offers a file-storage service, banking on the idea that distributing files across a decentralized network is safer than putting all your files in one cabinet.

Meanwhile, despite the fact that bitcoin was originally best knows we enabling illicit drug sales over the internet, blockchains are discovering adoption in some of the world’s largest corporations. Some big financial services companies, including JP Morgan and the Depository Trust& Clearing Corporation, are experimenting with blockchains and blockchain-like technologies to improve the efficiency of trading inventories and other assets. Merchants buy and sell inventories rapidly, but the behind-the-scenes process of transferring owned of those assets can take periods. Some technologists belief blockchains could help with that.

There are also potential have applied for blockchains in the seemingly boring world of corporate conformity. After all, storing records in an immutable ledger is a pretty good way to assure auditors that those records haven’t been tampered with.

It’s too early to say which experiments will work out or whether the results of successful experimentations will resemble the bitcoin blockchain. But the idea of creating tamper-proof databases has captured “members attention” of everyone from anarchist techies to staid bankers.

The First Blockchain

The original bitcoin software was released to the public in January 2009. It was open source software, meaning anyone could examine the code and reuse it. And many have. At first, blockchain fanatics sought to simply improve on bitcoin. Litecoin, another virtual currency based on the bitcoin software, seeks to offer faster transactions.

One of the first projects to repurpose the bitcoin code to use it for more than currency was Namecoin, a system for registering “.bit” domain names. The traditional domain-name management system–the one that helps your computer find our website when you type–depends on a central database, basically an address volume for the internet. Internet-freedom activists have long worried that this traditional approach attains censorship too easy, because governments can grab a domain name by forcing the company responsible for registering it to change the central database. The US government has done this several times to shut websites accused of committing violating gambling or intellectual-property laws.

Namecoin tries to solve this problem by storing. bit domain enrollments in a blockchain, which theoretically induces it impossible for anyone without the encryption key to change the registration information. To grab a. bit domain name, a government would have to find the person responsible for the website and force them to hand over the key.

What’s an “ICO”?

Ethereum and other blockchain-based projects have raised monies through a controversial practise called an “initial coin offering, ” or ICO: The inventors of new digital currencies sell a certain sum of the currency, usually before they’ve finished the software and technology that underpins it. The notion is that investors can get in early while committing developers the funds to finish the tech.The catch is that these provides have traditionally operated outside the rules and regulations meant to protect investors, although that’s starting to change as more governments examine the practice.

Bitcoin’s software wasn’t designed to handle other types of applications. In 2013, a startup called Ethereum published a newspaper outlining new ideas that promised to make it easier for coders to make their own blockchain-based software without having to start from scratch, without relying on the original bitcoin software. In 2015 the company liberated its platform for building “smart contracts, ” software applications that can enforce an agreement without human intervention. For instance, you could create a smart contract to bet on tomorrow’s climate. You and your gambling collaborator would upload the contract to the Ethereum network and then send a little digital currency, which the software would essentially hold in escrow. The next day, the software would check the climate and then send the winner their earnings. At least two major “prediction markets” have been built on the platform, allow people to bet on more interesting outcomes, such as which political party will win an election.

So long as the software is written correctly, there’s no need to trust anyone in these transactions. But that turns out to be a big catch. In 2016 a hacker made off with about $50 million merit of Ethereum’s custom currency intended for a democratized investment scheme where investors would pool their money and vote on how to invest it. A coding correct let a still unknown person to make off with the virtual money. Lesson: It’s hard to remove humans from transactions, with or without a blockchain.

Even as cryptography geeks plotted to employ blockchains to topple, or at the least bypass, big banks, the financial sector began its own experimentations with blockchains. In 2015, some of the largest financial institutions in the world, including JP Morgan, the Bank of England, and the Depository Trust& Clearing Corporation( DTCC ), announced that they would collaborate on open source blockchain software under the name Hyperledger. Several parts of software ought to have released under the Hyperledger umbrella, including Sawtooth, created by Intel for constructing custom blockchains.

The industry is already experimenting with using blockchains to attain security trades more efficient. Nasdaq OMX, the company behind the Nasdaq stock exchange, began letting private companies to use blockchains to manage shares in 2015, starting with a company called Chain. Similarly, the Australian Securities Exchange announced a deal to employ blockchain technology from a Goldman Sachs-backed startup called Digital Asset Holding to power the post-trade processes of Australia’s equity market.

The Future of Blockchain

Despite the blockchain hype–and many experiments–there’s still no “killer app” for the technology beyond currency supposition. And while auditors might like the idea of immutable records, as national societies we don’t always crave records to be permanent.

Blockchain supporters admit that it could take a while for the technology to catch on. After all, the internet’s foundational technologies were created in the 1960 s, but it took decades for the internet to become ubiquitous.

That said, the relevant recommendations could eventually show up in lots of places. For example, your digital identity could be tied to a token on a blockchain. You could then use that token to log in to apps, open bank accounts, apply for jobs, or prove that your emails or social-media messages are actually from you. Future social networks might be built on connected smart contracts that indicate your posts simply to certain people or enable people who create popular content to be paid in cryptocurrencies. Perhaps the most radical notion is using blockchains to handle voting. The team behind the open source programme Soverign built a platform that organizations, corporations, and even governments can already use to gather polls on a blockchain.

Advocates believe blockchains can help automate many duties now handled by lawyers or other professionals. For instance, your will might be stored in a blockchain. Or perhaps your will could be a smart contract that will automatically dole out your fund to your heirs. Or perhaps blockchains will supplant notaries.

It’s also entirely possible that blockchains will evolve into something completely different. Many of the financial industry’s experimentations involve “private” blockchains that run on servers within a single corporation and selected collaborators. In contrast, anyone can run bitcoin or Ethereum software on their computer and belief all of the transactions recorded on the networks’ respective blockchains. But big companies prefer to keep their data in the hands of a few employees, partners, and perhaps regulators.

Bitcoin proved that it’s possible to build an online service that operates outside the control of any one company or organisation. The task for blockchain proponents now is proving that that’s actually a good thing.
