Data recovery from accidentally deleted files or crashed drives in Redhat, CentOS and Fedora Linux

This tutorial will help you to recover data from accidentally deleted data from Linux-file systems. This is a very drastic mistake by any user/admin which costs for huge penalties. This script will be a boon for newbies/expert for data management. I will be using TestDisk for data-recovery. Here I have simplified the task with the help of a script.

Atlas 2.0 Trading Platform Announces Options on Bitcoin

Bitcoin Magazine -

Even though I was unable to find time to travel all the way to the U.S., I had the pleasure of watching Coinsummit’s live stream. Though the conference was focused on panels, there were a few company presentations. Only a couple really caught my attention in any meaningful way. One of these was Atlas ATS.

Their new platform, Atlas 2.0, is a Financial Information Exchange (FIX) protocol digital asset exchange claiming to be the first to announce options on Bitcoin. The exchange platform is ‘Wall Street grade’, and, besides options, it brings a high level of sophistication: trading major alt-coins, an array of advanced native order types for FIX API clients, derivative products, multi-sig transaction wallet, and a larger selection of advanced order types for clients using the FIX interface.

The Atlas 2.0 platform has been launched in Hong Kong and North America, where it has established the digital currency exchanges. The company is keen for the market to know that it has been deployed on a global, secure, and high precision private network. This network is exclusively managed under the Digital Currency Initiative (DCI), a division of Perseus Telecom.

Perseus is a private global high precision network provider for financial trading, gaming, e-commerce and multi-media. Customers include top tier market makers, banks, exchanges and Fortune 500 companies.

Perseus makes connecting to Atlas ATS simple, through a physical connection at any global location. Dr. Jock Percy, Chief Executive of Perseus, says they are “pleased to respond in tandem with Atlas ATS to the strong demand for diversified digital currency trading products accessible from any data centre in the world.”

He goes on to add that “Both companies are truly able to translate real asset class risk, reliability and latency concerns and to utilize this expert knowledge for the digital currency trading ecosystem.”

Shawn Sloves, Chief Executive at Atlas ATS notes that “Atlas ATS is pleased to expand (their) product offering to Options for our sophisticated global trading market participants.” He goes on to note that the company now offers “two types of option contracts, ‘Calls’ and ‘Puts’, which confer upon the owner the right to buy and sell, respectively, the underlying crypto-currency at a set ‘strike’ price on a given ‘expiration’ date.”

The absence of options trading for cryptocurrency is often lamented. Let’s hope this company can live up to its promise and deliver a viable platform. It would benefit the ecosystem greatly.

Atlas 2.0 supports three major alt-coins providing more products to trade and digital currency options for Bitcoin and Litecoin. Fees on options trades follow the maker/taker model. The rebate earned when adding liquidity is 0.1% and the fee for removing liquidity is 0.3%. Advanced order types are available via FIX API.

The platform supports trailing stop, stop limit, market, reserves, discretionary, and mid-point peg orders. Additional order types will be made available to website and Web API users in the next major platform upgrade.

Most importantly, the platform provides a new multi-sig wallet service for Improved Security. This multi-sig, read-only wallet with cold storage, is coin agnostic, supporting over 180 alt-coins.

The company will be adding additional alt coins over the next few weeks. They will also be expediting payment and banking services to create more options for funding trading accounts.

Atlas seems dedicated to providing a secure, state-of-the-art technology exchange platform for transacting digital currency. The services they promise to deliver, embarrassingly absent from the space until now, are exciting.

The company clearly has visions of being an industry leader in operating a trading venue and providing innovative products and services. If they are successful the benefit to the global trading community would be immense.

Competition from technology-driven markets increases overall market volumes and improves performance, providing benefits to all participants.

Federal Reserve Bank of St. Louis Really Gets Bitcoin

Bitcoin Magazine -

The Federal Reserve Bank of St. Louis recently held a “Dialog with the Fed” on bitcoin basics. The events are “designed to address the key economic and financial issues of the day and to provide the opportunity to ask questions of Fed experts.”

The discussions, which began in the fall of 2011, are held at the St. Louis Fed and its branches, and are free and open to the public. All discussions and presentations are archived.

While the event was broadcast, video is not up yet. However, the slide deck is, and it’s surprisingly funny and insightful. It goes through some basic elements of bitcoin, a sort of “Explain it to me like I’m 5” for central bankers.

Slide 6 describes Bitcoin’s source code size as about 17 MB (500 phonebooks), “About the size of a typical bill coming out of D.C. lately?” And it shows a touch of self-awareness. Under “Common Complaints,” the author writes “We hate banks… and we especially hate central banks.”

The deck describes bitcoin as a “Low-cost banking available to anyone in the world,” a “digital cash supply free of political manipulation,” and “a stroke of genius—a monetary system governed by a computer algorithm.”

And how funny that the Fed gets the Mt Gox debacle better than most journalists. “The wallets were ‘stolen’ – not Bitcoin’s fault.” Hear, hear.

Tackling the issue of “intrinsic value,” which the deck points out bitcoin doesn’t have, one slide asks, “What determines the market exchange rate between two intrinsically useless objects?” Welcome to currency, and life. No value is intrinsic.

As for how the Fed will deal with bitcoin, the deck acknowledges that “enforcing an outright ban is close to impossible.” Bitcoin adoption “will force traditional institutions to adapt or die.” And the most promising bit was close to the end, “Well-run central banks should welcome the emerging competition.” Indeed.

IRS Changes Course and Declares Bitcoin a Currency

IRS Changes Course and Declares Bitcoin a Currency

In a stunning reversal of intent, the IRS today issued a statement admitting they got it wrong.

“After further review, and speaking to our consulting organization led by new Treasury Secretary Jack Lew, we’ve decided that bitcoin acts more like a currency after all.” This was greeted with celebration at multiple companies which have been taking a harsh stance on the IRS’s previous declarations.

Overstock CEO Patrick Byrne issued a statement from a “Freedom Rally” that “Although the IRS has been used as a dangerous weapon against the Libertarian movement and has repeatedly shown hostile actions without legal recourse for Americans, “Once in a while they get one right.”

Agents in Police jackets labeled with IRS were seen taking several leaders from the peaceful rally into custody. When asked about the actions, two agents who declined to reveal their names as they were not authorized to speak to the press only admitted, “Hey we just do what we’re told.”

When asked to comment about the change in the IRS stance, former IRS leader “Lois Lerner” refused to answer questions and again invoked her Fifth Amendment right against self-incrimination.

Jack Lew admitted he had some influence in the decision and had just needed more time since his new role to head Treasury Department has just begun. “I just finished hanging my portrait of Barack Obama in my office and the new paint in the office renovation hasn’t even dried. I think the fumes of the wet paint might have led to the premature decision to treat the currency only as property.” The Treasury Secretary left open the possibility that they may change their mind again. “Never say Never,” he was quoted as saying when asked if this decision would be final.

The division of government known as FinCEN left open the possibility that they too might declare an official stance of how they intend to view bitcoin. According to Director Jennifer Shasky Calvery,  “We still don’t know what to call it. Sometimes we say it’s a Virtual currency, but we’ve been told it’s more like a Digital currency. Sometimes we call it a Cyber Currency – then other times we mention it is a Crypto Currency. Our official stance will be decided once we have a four square block drawn in chalk in the board room and release the chicken to decide which block to rest in = Whatever the chicken decides, we’ll do. Because of the four options, the usual method of Paper, Rock Scissors wouldn’t have worked,” she admitted.

There is still no word whether the Commodity Futures Trading Commission has declared bitcoin a commodity or currency. The Acting Chief Economist Sayee Srinivasan declared, “We still see ourselves in charge of the blockchain. We have a saying here – ‘If you can mine it, we can regulate it.’ So it is clearly our office responsibility to make that claim, and we clearly see ourselves in charge of it, no matter what the IRS says.” Although a SWAT team of IRS enforcement officers was standing in attendance during our interview, there are still some negotiations taking place between agencies. He would neither confirm nor deny that negotiations between federal agencies would ultimately be decided by “Indian Leg Wrestle”.

“One thing is for sure is that for this week probably it will remain a property. At least until Thursday when the final round of ‘Negotiation matches’ are scheduled to conclude,” he was quoted on the topic. When alerted of the IRS announcement of the reversal today, he smiled and told us any announcements before Thursday would not be the final word. “Since bitcoin hasn’t existed in our books until this year, we’ve got to settle things the old fashioned way, two out of three.  We are much more civilized since the dueling days of Alexander Hamilton and Aaron Burr.”

Pheeva: The Good iOS wallet

Bitcoin Magazine -

iPhone users, did you know that you can legally gain access to an iOS Bitcoin Wallet?

Love Will, LLC develops applications and provides services for the Cycle of Goodness, or C.O.G cooperative.

Among one of these apps is an innovative wallet by the name of Pheeva.

This is made possible through Apple’s enterprise software solutions reserved to companies like Love Will, LLC.

But it’s more than a way to get a Bitcoin wallet, it’s a way to work with a like-minded group towards a good cause and reap benefits.

Here’s how it works: Once you join and become a legal member of C.O.G., a registered state agency based in Kentucky, USA, you gain access to apps, including Pheeva, the iOS Bitcoin wallet, as well as the Google Chrome extension. There are more apps on the way.

“The purpose of the cooperative”, says Lafe Taylor, president of C.O.G., “is to provide members with the best applications and services in the bitcoin marketplace as well as offer them opportunities to share in the benefits of group economics through patronage points and refunds.”

Patronage points are the token by which members earn patronage. Patronage point allocation is determined by the board of directors, and can change from time to time to satisfy the needs of the Cooperative. Currently patronage points are awarded for referring others to join the Coop. All members receive 1 patronage point for joining the cooperative. If everyone chips in, everybody benefits.

Like many millions, Lafe Taylor likes the freedom behind bitcoin and the opportunity to disrupt the concept of money.

“We really desire to give back”, says Lafe.” Once I understood how bitcoin could revolutionize money for impoverished people,” he adds, “I was really excited about Bitcoin.”

You can check them out online at http://cogcoop.com or http://pheeva.com.
