In the search for Anaïs Nin, one of the first few links shows a picture of a man. Why? Since Nin is a woman, I can’t figure out why. Can you show some reason for this? Who is he? If you click on the picture a group of pictures of Nin and no mention of that man. Is it an error?

Repair the Yahoo Search App.

Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.

I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.

I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.

I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.

We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.

I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.

I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.

I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.

Bitcoin Mining

Securing the future of the Bitcoin Blockchain

Bitcoin Mining is the act of securing the Bitcoin Network through the verification of Bitcoin transactions. Since Bitcoin Mining is part of the infrastructure layer which powers the whole Bitcoin Network, every company, application and future innovation using the Bitcoin network rely on Bitcoin Miners to securely and efficiently process transactions.

Mining serves two purposes

Currency issuance of bitcoins by the Bitcoin Network to Miners.

Bitcoins are issued to a Miner when the Bitcoin Network recognises a Miner as the first to successfully solve the Block Chain Algorithmic Equation. New Bitcoins are issued by the network on average every 10 minutes until 21 million bitcoins have been released by the year 2140.

Securing the Bitcoin Network through the verification of Bitcoin transactions

When a Bitcoin transaction is performed, it will form part of the transaction ‘Block’. The chronological record of verified Bitcoin transactions is known as the Block Chain. Each Block within the Block Chain has its own Block Chain Algorithmic Equation and by solving the Block Chain Algorithmic Equation, Miners attach the Block to the Block Chain. The Block Chain is hosted by an online peer-to-peer network and shared by all Bitcoin users.

Mining Rewards

The amount of Bitcoins that are received by Bitcoin Group is determined by the company’s Hash Power as a percentage of the Global Bitcoin Network Hash Power. Higher levels of relative power will increase the chances of our operation solving the Blockchain algorithm and therefore create a greater likelihood of Bitcoin Group receiving the 25 Bitcoins currently released every 10 minutes plus transaction fees.

Hash Power Generation

Miners generate Hash Power by connecting and powering purpose built Bitcoin Mining machines, also known as ASIC Miners. As the amount of Bitcoin Miners operating and the scale of operations have increased, so too has the Mining difficulty. This has led to Bitcoin Mining machines becoming more powerful and efficient at solving the Bitcoin algorithm over time. Due to the benefits that access to the latest Mining technology brings, Bitcoin Group places great emphasis on developing strong relations with multiple Mining machine manufacturers. Currently Bitcoin Group’s Mining operation generates an average of 6.2 petahashes, which is approximately 1.19% of the Global Hash Power.

If you would like to learn more about the history of Bitcoin Mining, feel free to visit our Bitcoin Mining museum located at our Melbourne office.

Environmental Sustainability

Reducing our carbon footprint is one of our key considerations, given that the electricity requirements of our operations have significantly increased as their scale has expanded. It is because of this that Bitcoin Group has, where available, chosen to power its Mining operations through the use of renewable energy. Currently we generate up to 82% of our hash rate from hydroelectricity in China and geothermal energy in Iceland.

Major Cost for Mining

Electricity is often the largest cost associated with Bitcoin Mining, to minimise this Bitcoin Group actively seeks to operate in locations with low cost electricity. Access to such low cost electricity is most commonly found in China, which is why the majority of Bitcoin Group’s operations are based there. In addition to minimising costs, Bitcoin Group also seeks to minimise its environmental impact, as a result we aim to develop relationships with partners who possess sustainable energy sources.

Bitcoin Group Seeks to Launch World's First Bitcoin IPO

Bitcoin Group has announced it will pursue an initial public offering (IPO) in Australia. If successful, it would be the first bitcoin company to offer its shares to the public in an IPO.

The Melbourne-based firm offers a cryptocurrency arbitrage service, but plans to turn mining into its main revenue source if its offering is approved.

Bitcoin Group's chief executive, Sam Lee, said:

"We believe for bitcoin businesses in the mining industry be taken seriously they need to first have the transparency, accountability and legitimacy of a listed company."

Bitcoin Group aims to raise AU$20m from the sale of 100 million shares at AU$0.20 a share, and would trade on the Australian Securities Exchange (ASX), according to the Sydney Morning Herald.

Emphasis on mining

Notably, Lee also runs Bitcoins Reserve, an offshore cryptocurrency arbitrage fund whose operations will be folded into Bitcoin Group. The fund claims a return of 765% to its clients for the 12 months ended from 24th May, according to its prospectus.

However, if the company raises the expected capital from a share offering, Lee wants to focus the firm's efforts on mining instead.

Bitcoin Group has already engaged with mining rig makers and signed an agreement with an electricity supplier in anticipation of starting its mining business, according to an investor presentation.

Lee says Bitcoin Group will remain "hardware agnostic" although he added that he planned to use some of the proceeds from the listing, if it goes through, to invest in ASIC chip makers.

"Our role is to provide a transparent, accountable and legitimate vehicle for our investors to gain exposure to bitcoin mining, which is currently one of the most profitable segments within the industry," Lee said.

Australia regulatory regime shaping up

Bitcoin Group has announced its listing plans as Australia's regulatory regime for digital currencies begins to take shape. In August, the Australian Tax Office (ATO) published guidance on the tax treatment of digital currencies for the first time.

Under the ATO guidance, digital currencies could be subject to both capital gains and goods and services taxes. This means that buying bitcoin on an Australian exchange, for example, would incur the additional 10% goods and services tax.

While some digital currency companies in Australia welcomed the clarity created by the ATO guidance, many disagreed with the tax treatment. Non-profit advocacy group Bitcoin Association of Australia, for example, said at the time that the treatment placed an "onerous" administrative burden on companies who would be required to keep detailed records of transactions.

Australian exchange and payment processor CoinJar began imposing GST on bitcoin sales from 3rd October, although it has stated that it supports changes to the current tax treatment guidelines.

For Bitcoin Group, the ATO's guidelines are critical to its listing plans. Lee interprets the tax authority's moves, despite the drawbacks in its tax treatment, as largely positive for bitcoin companies there.

"The ATO guidance from our point of view is workable and comprehensive [. ] To have a clear position from the ATO is better than not having one at all," he said.

A senate inquiry into digital currency tax treatment and other implications has also been announced, with the findings to be presented next March.

Publicly traded bitcoin companies

While Bitcoin Group would claim the mantle of being the first company dealing in bitcoin to make an IPO, it wouldn't be the only public bitcoin company. Two other firms, digitalBTC and Bitcoin Shop, also have shares traded publicly, although they both achieved this through "backdoor listings".

DigitalBTC is a mining firm that is also listed on the ASX. It raised AU$9.1m in a reverse takeover of a fund that invested in natural resources called Macro Energy in March. Its stock price has risen from under AU$0.05 then to AU$0.20 today.

The firm reported a loss of $11.2m for the year, although it said its bitcoin mining and trading business generated a pre-tax profit of $2.4m. The firm said the net loss was due to an accounting expenditure of $10.9m incurred by the reverse takeover.

DigitalBTC stock price

Bitcoin Shop is an e-commerce platform that is traded on the OTCQB market in the US. It has run into trouble recently, with its management foregoing salaries in a bid to reduce expenses. Its share price has fallen from $5.26 when it completed its reverse takeover of TouchIT Technologies in February to $0.08 today.

Bitcoin Group's Lee points to digitalBTC's share offering as a sign that the Australian investing public has an appetite for bitcoin stocks. He also believes that a listed entity would give customers the transparency and consumer protections that aren't guaranteed by privately held mining firms.

"Me and other local bitcoiners have been misled by over ambitious delivery dates of certain mining companies in the past, but due to the companies operating as private entities, investors and customers have no recourse to receive fair treatment," he said.

Bitcoin mining pools are a way for Bitcoin miners to pool their resources together and share their hashing power while splitting the reward equally according to the amount of shares they contributed to solving a block.

A "share" is awarded to members of the Bitcoin mining pool who present a valid proof of work that their Bitcoin miner solved. Bitcoin mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.

The solution to this problem was for miners to pool their resources so they could generate blocks quicker and therefore receive a portion of the Bitcoin block reward on a consistent basis, rather than randomly once every few years.

Network Consensus

If you solo-mine, meaning you do not mine with a Bitcoin mining pool, then you will need to ensure that you are in consensus with the Bitcoin network. The best way is to use the official BitCore client.

If you participate in a Bitcoin mining pool then you will want to ensure that they are engaging in behavior that is in agreement with your philosophy towards Bitcoin.

For example, some rogue developers have threatened to release software that could hard-fork the network which would likely result in tremendous financial damage.

Therefore, it is your duty to make sure that any Bitcoin mining power you direct to a mining pool does not attempt to enforce network consensus rules you disagree with.

Segregated Witness

When segwit is activated, you will want to be able to mine and relay segwit-style blocks. The following mining software has been upgraded to support segwit.

Please note that software that supports the GetBlockTemplate (GBT) RPC must be upgraded to support the BIP9 and BIP145 changes to GBT. All the programs linked above that support GBT have been upgraded.

Segwit is already activated and enforced on testnet, so you may find it useful to test your infrastructure upgrade by mining with some small amount of hashrate on testnet. Alternatively, Bitcoin Core 0.13.1’s regression test mode (regtest) also supports segwit by default.

Bitcoin Mining Pools

There are many good Bitcoin mining pools to choose from. Although it's tempting to pick the most popular one, it's better for the health of the network to mine with smaller pools so as to avoid potentially harmful concentration of hashing power.

The hash rate distribution is best when split among more Bitcoin mining pools.

Bitcoin Mining Pool Hash Rate Distribution

Bitcoin Mining Pool Options

For a fully decentralized pool, we highly recommend p2pool.

The following pools are believed to be currently fully validating blocks with Bitcoin Core 0.11 or later:

BTCC: BTCC is a Bitcoin exchange, wallet, and mining pool located in China. Its mining pool currently controls around 15% of the network hash rate.

Slush Pool: Slush Pool is run by Satoshi Labs, a Bitcoin company based in the Czech Republic. Slush Pool was the first mining pool and maintains around 7% of the network hash rate.

Antpool: [WARNING] - Bitmain operates Antpool and some consider them to be a malicious actor in the Bitcoin ecosystem because of the AntBleed scandal where they were intentionally including malware within mining equipment they sell. In a corporate communication, Bitmain claimed this was a feature and not a bug. This malware would enable Bitmain to remotely shut down equipment of customers or competitors thus increasing their own profitability. Additionally, such behavior could pose a risk to the entire Bitcoin network.

Eligius: Eligius was one of the first Bitcoin mining pools and was founded by Luke Dashjr, a Bitcoin Core developer. Today, the pool controls just under 1% of the network hash rate.

BitMinter: BitMinter, once one of the largest Bitcoin mining pools, now controls less than 1% of the network hash rate.

Kano CKPool: Kano CKPool was founded in 2014 and currently has around 3% of the network hash rate under its control.

F2Pool: F2Pool is the second largest Bitcoin mining pool, with around 25% of the network hash rate. Its user interface is in Chinese, making it difficult for English speakers to join.

BW Pool: BW Pool controls around 7% of the network hash rate. Like F2Pool, its user interface is in Chinese, making it difficult for English speakers to join.

Bitfury: Although seen publically in block explorers and hash rate charts, BitFury is a private mining pool and cannot be joined.

Bitcoin Mining Pool Payment Methods

Calculating your share of the bitcoins mined can be complex. In an ongoing effort to come up with the fairest method and prevent gaming of the system, many calculation schemes have been invented. The two most popular types are PPS and DGM. PPS, or 'pay per share' shifts the risk to the mining pool while they guarantee payment for every share you contribute.

PPS payment schemes require a very large reserve of 10,000 BTC in order to ensure they have the means of enduring a streak of bad luck. For this reason, most Bitcoin mining pools no longer support it.

One of the few remaining PPS pools is EclipseMC. DGM is a popular payment scheme because it offers a nice balance between short round and long round blocks. However, end users must wait for full round confirmations long after the blocks are processed.

PPS: The Pay-per-Share (PPS) approach offers an instant, guaranteed payout for each share that is solved by a miner. Miners are paid out from the pools existing balance and can withdraw their payout immediately. This model allows for the least possible variance in payment for miners while also transferring much of the risk to the pool's operator.

PROP: The Proportional approach offers a proportional distribution of the reward when a block is found amongst all workers, based off of the number of shares they have each found.

PPLNS: The Pay Per Last N Shares (PPLN) approach is similar to the proportional method, but instead of counting the number of shares in the round, it instead looks at the last N shares, no matter the boundaries of the round.

DGM: The Double Geometric Method (DGM) is a hybrid approach that enables the operator to absorb some of the risk. The operator receives a portion of payouts during short rounds and returns it during longer rounds to normalize payments.

SMPPS: The Shared Maximum Pay Per Share (SMPPS) uses a similar approach to PPS but never pays more than the Bitcoin mining pool has earned.

ESMPPS: The Equalized Shared Maximum Pay Per Share (ESMPPS) is similar to SMPPS, but distributes payments equally among all miners in the Bitcoin mining pool.

RSMPPS: The Recent Shared Maximum Pay Per Share (RSMPPS) is also similar to SMPPS, but the system prioritizes the most recent Bitcoin miners first.

CPPSRB: The Capped Pay Per Share with Recent Backpay uses a Maximum Pay Per Share (MPPS) reward system that will pay Bitcoin miners as much as possible using the income from finding blocks, but will never go bankrupt.

BPM: Bitcoin Pooled mining (BPM), also known as "Slush's pool", uses a system where older shares from the beginning of a block round are given less weight than more recent shares. This reduces the ability to cheat the mining pool system by switching pools during a round.

POT: The Pay on Target (POT) approach is a high variance PPS that pays out in accordance with the difficulty of work returned to the pool by a miner, rather than the difficulty of work done by the pool itself.

SCORE: The SCORE based approach uses a system whereby a proportional reward is distributed and weighed by the time the work was submitted. This process makes later shares worth more than earlier shares and scored by time, thus rewards are calculated in proportion to the scores and not shares submitted.

ELIGIUS: Eligius was designed by Luke Jr., creator of BFGMiner, to incorporate the strengths of PPS and BPM pools, as miners submit proofs-of-work to earn shares and the pool pays out immediately. When the block rewards are distributed, they are divided equally among all shares since the last valid block and the shares contributed to stale blocks are cycled into the next block's shares. Rewards are only paid out if a miner earns at least. 67108864 and if the amount owed is less than that it will be rolled over to the next block until the limit is achieved. However, if a Bitcoin miner does not submit a share for over a period of a week, then the pool will send any remaining balance, regardless of its size.

Triplemining: Triplemining brings together medium-sized pools with no fees and redistributes 1% of every block found, which allows your share to grow faster than any other Bitcoin mining pool approach. The administrators of these Bitcoin mining pools use some of the Bitcoins generated when a block is found to add to a jackpot that is triggered and paid out to the member of the pool who found the block. In this way, everyone in the pool has a better chance to make additional Bitcoins, regardless of their processing power.

One of the largest hedge funds in the world is ready to add bitcoin to its 'investment universe'

George Rotariu uses the first bitcoin ATM in downtown Bucharest June 27, 2014. Bogdan Cristel/Reuters

• Man Group, a UK-based investment management firm, said it would include bitcoin in its "investment universe" if bitcoin futures successfully launch.
• CME, the world's largest exchange group, said it would launch a bitcoin futures product by year-end.
• Such a product could open the door to more traditional Wall Street firms entering the bitcoin market.

One of the largest hedge funds in the world might hop on the bitcoin trade.

Luke Ellis, the CEO of Man Group, the UK-based investor with $103.5 billion in funds under management, said the firm would include bitcoin in its "investment universe" if bitcoin futures successfully launch, according to a Reuters report.

Ellis said during the Reuters Global Investment Outlook Summit in the UK that cryptocurrencies "are an interesting thing."

"It's not part of our investment universe today - it could be," Ellis said. "If there is a CME future on bitcoin, it would be."

CME announced at the end of October that it would launch a bitcoin futures product by year-end. On Monday, CME chairman and CEO Terry Duffy said such a product would likely be ready by the second-week of December.

The launch of bitcoin futures by an established exchange will likely translate into wider participation in bitcoin trading by other Wall Street firms since such firms are already plugged into their systems for other products. It will also likely dampen volatility for the coin, which is known for its wild price swings.

This post has been updated to reflect Man Group's most up-to-date funds under management.

CIO Review: Insuring Bitcoin Technology by Ty Sagalow (March 2015)

CIO REVIEW MAGAZINE, (MARCH 9, 2015) In the mid to late 1990s, the insurance industry was struggling with “the Y2k crisis”, not only in connection with its own systems, but more importantly, with the systems of all their policyholders. As the Chief Underwriting Officer of one of the largest subsidiaries of one of the largest insurance companies in the world, AIG, it was my task to determine our potential exposure if the computer systems of our policyholders failed. My conclusion: hundreds of millions dollars of potential liability payouts.

This was the insurance industry’s first introduction to the hazards of insuring technology. To reduce that exposure, we had to figure out a way to motivate our corporate policyholders to take reasonable steps to manage their Y2k problem. Since one of the central purposes of an insurance policy is to motivate specific risk reducing behavior, such as wearing a seat beat, the question became how to apply that rule to motivate risk reduction behavior in connection with the impending “date configuration” problem.

So we created “Y2k insurance”, and made it available only to those companies who took the right steps to reduce their exposure.

Beginner’s Guide to Mining Bitcoins

Last updated on May 18th, 2018 at 03:08 pm

One of the biggest problems I ran into when I was looking to start mining Bitcoin for investment and profit was most of the sites were written for the advanced user. I am not a professional coder, I have no experience with Ubuntu, Linux and minimal experience with Mac. So, this is for the individual or group that wants to get started the easy way.

1. Get a Bitcoin mining rig

Bitcoin mining is a very competitive niche to get into. As more and more miners come on board with the latest mining hardware the difficulty to mine increases each day. Before even starting out with Bitcoin mining you need to do your due diligence. This means you need to find out if Bitcoin mining is even profitable for you.

The best way to do this is through the use of a Bitcoin mining calculator. Just enter the data of the Bitcoin miner you are planning on buying and see how long it will take you to break even or make a profit. However, I can tell you from the get go that if you don’t have a few hundred dollars to spare you probably won’t be able to mine any Bitcoins.

Once you’ve finished with your calculations it’s time to get your miner. Make sure to go over our different Bitcoin mining hardware reviews to understand which miner is best for you. Today, the Antminer S9 is the newest and most powerful miner.

Antminer R4

Antminer T9

AntMiner S7

AntMiner S5

Antrouter R1

As a side note it’s important to state that in the past it was possible to mine Bitcoins with your computer or with a graphics card (also known as GPU mining). Today however, the mining niche has become so competitive that you’ll need to use ASIC miners – special computers built strictly for mining Bitcoins.

2. Get a Bitcoin wallet

First thing you need to do is get a “Bitcoin Wallet“. Because Bitcoin is an internet based currency, you need a place to keep your Bitcoins. Once you have a wallet make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address but most wallets are pretty straight forward about it. Notice that you’ll need your PUBLIC bitcoin address and not your PRIVATE KEY (which is like a password for your wallet).

If you’re using a self hosted wallet (i.e. you downloaded a program to your computer and are not using an internet based service) there’s one additional very important step. Make sure you have a copy of the wallet.dat file on a thumb drive and print a copy out and keep it in a safe location. You can view a tutorial on how to create a secure wallet here. The reason is that if you computer crashes and you do not have a copy of your wallet.dat file, you will lose all of your Bitcoins. They won’t go to someone else, they will disappear forever. It is like burning cash.

3. Find a mining pool

Now that you have a wallet you are probably roaring to go, but if you actually want to make Bitcoin (money), you probably need to join a mining pool. A mining pool is a group of Bitcoin miners that combines their computing power to make more Bitcoins. The reason you shouldn’t go it alone is that Bitcoins are awarded in blocks, usually 12.5 at a time, and unless you get extremely lucky, you will not be getting any of those coins.

In a pool, you are given smaller and easier algorithms to solve and all of your combined work will make you more likely to solve the bigger algorithm and earn Bitcoins that are spread out throughout the pool based on your contribution. Basically, you will make a more consistent amount of Bitcoins and will be more likely to receive a good return on your investment.

When choosing which mining pool to join you will need to ask several questions:

• What is the reward method? – Proportional/Pay Per Share/Score Based/PPLNS
• What fee they charge for mining and withdrawal of funds?
• How frequently they find a block (means how frequently I get rewarded)?
• How easy it is to withdraw funds?
• What kind of stats they provide?
• How stable is the pool?

To answer most of these questions you can use our best Bitcoin mining pools review or this excellent post from BitcoinTalk. You can also find a complete comparison of mining pools inside the Bitcoin wiki. For the purpose of demonstration I will use Slush’s Pool when mining for Bitcoins. Once you are signed up with a pool you will get a username and password for that specific pool which we will use later on.

Follow the link to go to their site and click the “Sign up here” link at the top of their site and follow their step by step instructions. After you have your account set up, you will need to add a “Worker”. Basically, for every miner that you have running, you will need to have a worker ID so the pool can keep track of your contributions.

4. Get a mining program for your computer

Now that you’ve got the basics covered we’re almost ready to mine. You will need a mining client to run on your computer to that you will be able to control and monitor your mining rig. Depending on what mining rig you got you will need to find the right software. Many mining pools have their own software but some don’t. You can find a list of Bitcoin mining software here.

I’m using a mac so I will use a program called MacMiner. The most popular program I’ve found for a PC are BFGMiner and 50Miner . If you want to compare different mining software you can do this here.

5. Start mining

OK, so hopefully now everything is ready to go. Connect you miner to a power outlet and fire it up. Make sure to connect it also to your computer (usually via USB) and open up your mining software. The first thing you’ll need to do is to enter your mining pool, username and password.

Once this is configured you’ll basically start mining for Bitcoins. You will actually start collections shares which represent your part of the work in finding the next block. According to the pool you’ve chosen you will be paid for your share of coins – just make sure that you enter your address in the required fields when signing up to the pool. Here’s a full video of me mining in action:

Conclusion – perhaps it’s better just to buy the coins?

To conclude this article here’s something to consider. Perhaps it would be more profitable for you to just buy Bitcoins with the money you plan to spend on Bitcoin mining. Many times just buying the coins will yield a higher ROI (return on investment) than mining. If you want to dig into this a bit deeper here’s a post about exactly that.
