You are losing money now by mining bitcoin




Bitcoin mining was once, as close as you could get to free money. You plugged in your computer, which began solving complicated mathematical problems on the bitcoin ledger, and you were rewarded with bitcoin.
Now, 10 years on since the first bitcoin was mined, competition to solve these complicated puzzles on the blockchain has surged making that free money not so free.
In fact, it’s become so saturated that retail miners who are plugging in their PCs, hoping to earn a quick buck, are now losing money, according to data from Diar, a blockchain and data analytics firm.
The company says the rise of institutional mining companies have squeezed retail miners margins. “Bitcoin miner revenues in the first 6-months of this year surpassed all earnings of 2017,” said Diar. “To date, revenues have exceeded last year by a whopping $1.4Bn. But the record hash rate hit at the end of August saw miners paying retail electricity prices move to unprofitability for the first time in September.”
Mining profitability
The hash rate is a measure of the computing power required to confirm a bitcoin transaction. As competition swelled, so did the hash rates, which in turn drove up electricity bills as miners scrambled to ramp up their mining equipment.
However, these costs have reached levels where only institutional companies can foot the lofty electricity bills, Diar research found. “The investment proposition for smaller miners held true throughout most of this year, but has since become questionable on the back of an increase of computing power competing for the coinbase reward.”
In May, an Elite Fixtures survey found that the average cost to mine a bitcoin in the U.S. was $4,758. But rising electricity prices and mining hardware costs would suggest this average cost has climbed.
Hash rate
Furthermore, the plight of miners has been exasperated by the decline in the price of bitcoin. BTCUSD, -0.48% The world’s largest digital currency has fallen more than 50% year-to-date and is down more than 60% from its all-time high on Dec. 17, 2017.
So for retail investors, unless you’re a student pilfering electricity from your dorm room, rewards from mining are dwindling away. “With big mining operations on low electricity costs running at anywhere between 50-60% gross profit from bitcoin revenues, the market has a lot of room left to grow and, profits to squeeze,” said Diar.
“But bitcoin mining has, at least for now, and most likely in the future, moved into the court of bigger players with deep pockets.”

You thought that only heads of states and countries or authorities of importance needed a bunch of beefed up security guards protecting them. Well, here’s something new. Quite a few chief executives, founders and heads of billion dollar global companies have been threatened by unstable customers and users.

This has prompted many of them to hire guards for protection. Mark Zuckerberg, founder and CEO of the social media mammoth Facebook recently increased his security convoy to 16 guards. Zuckerberg was in the news last month for his efforts to build an Artificial Intelligence assistant.

Page Six informs that Facebook has been instrumental in a many break ups and divorces. As a result, users get mad at the website, blaming it unfairly. On top of that, Facebook reported more than a billion “daily active users on average” for December 2015 that might mean that the number of disgruntled and unstable subscribers would be high for this website. Is that why Zuckerberg had to ramp up his army of guards?

Silicon Valley sources point out that as global CEOs, people like Zuckerberg are reaching billions of people every day hence threats from any corner are unnerving. Most CEOs take these very seriously, especially if these extend to the immediate family.


According to The Sun, the 16-people team of security personnel guard Zuckerberg’s properties in San Francisco and California. These bodyguards are patrolling his AU$14 million (£7 million) home in San Francisco and AU$10 million (£5 million) home in Palo Alto, California. The guards work day and night in shifts to ensure the safety of the Facebook founder as well as his wife Priscilla Chan and their two-month-old daughter, Maxima.

However, it seems like the security personnel have managed to annoy the neighbours. News.com.au states that the neighbours have already levelled accusations against the guards for “permanently … illegally” taking up two prime parking spots in the area. Letters have been sent already, but the guards were said to have been instructed by their supervisors to not move the cars under any circumstances, reveals the annoyed neighbours.
Publications have contacted Facebook for comments. However there hasn’t been any response from the company as of this time.

THERE’S just something about bubble wrap that we can’t get enough of.


Yes, it’s really useful when it comes to fragile packages — but we all know the true joy comes from popping those little plastic bubbles.

And now, the fun doesn’t have to be limited to birthdays, Christmas or online delivery days — thanks to a little toy that mimics the addictive sensation, without the crushing disappointment of realising you’ve burst all of the bubbles.

The “Mugen Puchipuchi” — a small keychain with eight “bubbles” — is made using a double layer structure of silicone rubber to create a similar feeling to the real deal..

“Mugen” is Japanese for “infinite”, representing the infinite number of bubbles its users will pop. Meanwhile, “Puchipuchi” is the Japanese word used to describe the plastic wrap’s unmistakeable popping sound.


There’s even a phone case version — which, presumably, would also offer outstanding protection for your mobile.


The original Japanese keychain is quite an investment at $78, but luckily the phone case version can be picked up for as little as $10.

Whichever you choose, the popping satisfaction will be well worth it.








How does FB bind over one billion people every day?


Well, it's a combination of tools we have built up over the last 11-12 years. We make sure that in as many possible cultures, we are on the ground, looking over people's shoulders, literally. Using, logging in, understanding - oh, this word didn't quite make sense; last name quite didn't make sense; oh, the way you said invalid password, I didn't totally understand what that meant. At the scale of a billion people, each of these issues is a big deal. And we need to have a system that lets us go out, understand, prioritize and address each of these product issues.


How are people using FB and how do you interpret that and design for the future?


Today, we can discover opportunities to improve emerging behaviour. Instant Articles is just one example. We are seeing more people using FB to share or discover news. We know a lot of these people are in places where news can take more than 30 seconds to load, we know that could be the difference in reading the article or not reading it. Thus was born a team to make that experience immediate. That's how auto-play videos were born. We saw people were using groups to buy and sell things. And so, we are working on making commerce in groups easier - building basic features that let people more easily search and list prices.


What happened to the 'dislike' button?



'Reactions' as a feature is getting tested in five countries. And we are going to roll it out soon. We built this elegant design, where you just press and hold the 'like' button, you get a little menu of animated emotions which you can slide your finger across and leave one of these reactions. And what's so cool is that when you would be scanning your News Feed, you would get a visceral sense of the feel that people are having around a piece of content.



To what extent would you say that FB has replaced email?

Messaging is a massive trend on mobile. No one had thought it would grow so big, so fast. We really see FB and Instagram on one end of the spectrum, which is communicating with many people. And then Messenger and WhatsApp on the other end, which is communicating more frequently but with less people. Making messaging better on mobiles is an important trend in technology. It's not just text messages, its sending photos and videos. It's how we talk, it's sending voice clips, it's sending stickers and money. I would say that is the thing which is replacing email.



What is the comparison between desktop and mobile at FB?



We still have hundreds of millions of people each day using FB on desktop. Desktop is not going away. Especially at work, a lot of people are using PCs. We are working on a product called Facebook at Work, which will let you use Facebook specifically with your colleagues. But mobile is the most important technological trend of our time, it is the gateway to the internet for so many people for the very first time.







Microsoft is ending support for older versions of Internet Explorer, as the company turns its focus to new browser Microsoft Edge




Google is testing an identification system which does not require a password, according to leaks reported by Reddit and backed up by the Android Police website.

This new feature, which is in the test phase, is based on the idea of notification. Rather than entering a password, Google account holders sign in via a notification received on their smartphone which enables them to log in.

While this method could prove to take a little longer than entering a password, its aim is to improve security. At any time, users can reverse their decision and sign in using a password, for example when there is no network.

Google is not the only major operator to offer an alternative to the traditional password.

Yahoo!, for example, offers its Key Account system via the latest update to its Yahoo Mail app for mobile. This system also involves sending a notification to a smartphone via the owner's email address when they want to open their mailbox from any device. All users have to do is click on "yes" on their smartphone to confirm they want to access the mailbox, without having to remember their password.

Other operators prefer to use biometry, as Microsoft does with Windows 10 via two recognition systems, Hello (signing into the operating system and unlocking devices without a password) and Passport (for apps). The idea is not to have to store passwords on external servers which can be hacked at any time.

Using passwords is a potential security weakness, particularly given that the favorites are still "123456", "password" and "qwerty", according to SplashData.





Barely a few days after Microsoft launched Cortana for Android in the US, the company has now disabled the digital-assistant handsfree feature on Android. The problem apparently stems from some incompatibilities with ‘OK Google’ feature of Google Now.


In conversation with VentureBeat, a Microsoft spokesperson stated, “We’ve received user feedback that the ‘Hey Cortana’ feature is conflicting with Android voice search and are temporarily disabling the feature while we evaluate a solution.” In layman words, Microsoft’s digital assistant Cortana is conflicting with Google’s very own digital assistant Google Now and thats why, the company has temporarily disabled to feature, till they reach a solution.


Currently, the app is only available to users in the US and China. The app’s changelog on Google Play Store for the latest version includes improved app stability and enhanced call and text features. But the bullet point states, removed ‘Hey Cortana’ feature for US market, added the report.


In November this year, Microsoft announced that Cortana would be available in India after adapting her to the cultural nuances of India and learning the Indian accent.


For now, Cortana will work only in English and Microsoft has made spruced it up to understand Indian accent. Besides, the company has also introduced an Indian voice. It also understands Indian terms such as festivals, India-specific food and popular game of cricket.





Twitter has warned some of its users that they may have been targeted in an attack by state-sponsored hackers.

This is the first time that the social media website has issued such an alert, but companies like Google and Facebook have issued similar warnings in the past to their respective users.

"We believe that these actors (possibly associated with a government) may have been trying to obtain information such as email addresses, IP addresses and/or phone numbers," Twitter said in its notification, which some recipients then posted on their Twitter feeds.

It's unclear how many users were warned, but Twitter said that only a "small group of accounts" may have been targeted. Many users who acknowledged having received the message are privacy advocates and security researchers, some of whom tweet under pseudonyms.

Twitter referred potentially targeted users to the Tor Project and the Electronic Frontier Foundation for tips on how to protect their identities online.

Recommending Tor is a bit ironic, since Twitter was accused in the past of blocking users who accessed its website via Tor and forcing them to verify their accounts by providing phone numbers -- the same phone numbers that "state-sponsored actors" are now supposedly trying to access in order to identify activists who tweet anonymously.





Facebook’s privacy policy has always been a bit of an enigma, and that makes a lot of people just ignore it entirely (despite the terrifying amount of things Facebook knows about you). But not considering how your actions on Facebook could affect your financial life is a big mistake, as many people have found out over the past few years. Here are five ways that your actions on Facebook could cost you money if you’re not careful.
Your Credit Score

Your credit score is a very important part of your overall financial health—if your score is high, you’re likely to get approved for loans or credit cards with lower interest rates than you would if your score was low. This is why it’s important to do what you can to keep your credit score as high as possible.



When determining your credit score, the three big providers—TransUnion, Equifax, and Experian—look at a wide range of factors. How many loans and credit cards you’ve had in the past, whether you made your payments on time, and so on. But they may soon be looking at your Facebook history, too. Naked Security reported that finance giants are looking into using social media as a metric of trustworthiness. According to FICO CEO William Lansing,


“If you look at how many times a person says ‘wasted’ in their profile, it has some value in predicting whether they’re going to repay their debt.

It’s not much, but it’s more than zero.”

It’s not clear how these companies would gain access to this sort of information, but it’s safe to assume that if they adopt this as a regular practice, they’ll be pretty good at it. Better spend some time cleaning up your Facebook profile if you’re looking to get a loan anytime soon.
Scams

The Internet is full of scams; email scams, website scams, online dating scams, and, predictably, social media scams. A few years ago, the Facebook lottery scam was popular, in which users would be contacted and told that they won a lottery, either directly from Facebook or through a well-known lottery like Powerball. Then those users would be fleeced for handling fees and other sums of money that would go directly to the scammers.



The “Nigerian”-style scam is still alive and well on Facebook, and there are a number of others that pop up every once in a while—because they continue to work. And one way to make sure that you’re more likely to get scammed is to give out personal information on Facebook. If you post your credit score, any information about your bank, personally identifying information, or anything else that’s unique to you, scammers have extra ammunition for making themselves look more convincing.

By including that information in an email or Facebook message to you, the scammers make themselves look much more legitimate. Don’t give away personal information on Facebook, and it’ll be easier to spot a potential scam.
Impersonation

Earlier this month, a jockey named Michelle Payne was the first female jockey to win the Melbourne Cup, a huge sporting event in Australia. Her odds were given at 100-to-1. What does this have to do with Facebook? A few people bet on Payne, and were so excited when they won that they posted selfies with their winning tickets. Bad idea.



By the time they got to the payout machines, someone else had already used the Facebook photo to make a fake of the ticket and cashed almost A$1000. Hopefully the perpetrators will be caught and the money returned to the rightful winners, but this should serve as a lesson to anyone else thinking about posting a selfie on Facebook.

Any other information you give out could also potentially be used by someone to impersonate you online—even things as simple as the street you grew up on could be used as a security question for an account, so think twice about what you post.
Freebooting

Popular YouTube users can make a huge amount of money through ads and paid product placement, but that money can be derailed by freebooting, the process of downloading a video and reposting it under one’s own name. A great example of this is SketchShe’s Mime Through Time, a popular and fun video that shows three comediennes lip syncing with songs from a number of different eras.


A number of people downloaded the video and reposted it to Facebook, meaning that millions of views weren’t directed through YouTube, where SketchShe would have made a lot of money from ad views. This was done without their consent or knowledge, and is a form of copyright infringement.

And while you probably won’t be affected by this, it’s a good thing to keep in mind. When you share videos, make sure that you’re sharing the official versions to give credit where it’s due and prevent the proliferation of this perfidious perpetration.
Jobs

Much like credit bureaus, employers are also interested in your Facebook history and activity. When you apply for a job, you can bet that the company will Google your name to see if anything suspicious comes up, and to see what they can find out on Facebook. If your Facebook profile makes you look like a bad employee, you might not get the job.



You can also get fired from your job for what you do on Facebook. Business Insider ran an article last year detailing 17 times when people were fired for their Facebook activity. A waitress complained about customers and lost her job, three flight attendants shared information they weren’t supposed to and got fired, a teacher was let go for posting creepy Facebook comments on students’ posts… the list goes on.

Long story short: don’t be stupid on Facebook. It could cost you your job. (And if it gets you in the news, it could cost you a lot of future potential jobs, as well.)
Use Some Common Sense

For the most part, if you use some basic social media common sense, Facebook won’t cause you to lose any money. Be careful about the pictures you post, be suspicious of anyone who gets in touch and asks for information, and don’t use Facebook to say anything you wouldn’t want your boss to hear. Stick to those principles, and you’ll be fine.

Has Facebook cost you any money? Do you know anyone who’s had one of these experiences? Share your thoughts below so we can all be a bit smarter about how we use social media!













Google has largely avoided this problem by keeping in-app advertising discreet, while Microsoft has pivoted free email into a loss leader for its other products.

A thread on the Adblock Plus forums contained complaints from a couple of people who couldn't access Yahoo Mail on both Chrome and Firefox. Instead of seeing their inboxes, the get the following error message: "Uh oh..."






Soon, you may see a warning in Gmail that tells you that an email has arrived over an unencrypted connection.

Gmail HTTPS encryption is already used by itself as a default for connections between servers and browsers, but for quite a long time the standard for e-mails was to leave them unencrypted. The good news is that email security is getting better. “When you send or receive emails with one of these providers, these messages are as open to snoopers as a postcard in the mail”, said Google in a blog post.


If you’re like most entrepreneurs, you keep hearing about the growing clout of social media, but you’ve never seen any evidence it can help your business. And without any realistic expectation of payback, why should you invest time figuring this stuff out?




Android Pay, Google's own mobile payment system that uses smartphones running Android to pay for things, could launch in the U.S. as soon Aug. 26, according to photos distributed to several McDonald's restaurants.


The photos obtained by Android Police inform McDonald's managers and crew members on what mobile payments are and how to accept them.


"This month, customers will be able to start using Samsung and Android mobile devices to pay for their orders," reads one notification sent out to McDonald's staff.




Another photo posted to reddit by user BlackMartian also reportedly corroborates Android Pay's launch later this week:





The above photo, along with Android Police's own spottings reveals participating Android Pay partners will also begin receiving decals to affix to point-of-sale terminals (POS) to inform customers they can pay with their phones.


Google has yet to announce an official launch date for Android Pay, its Apple Pay rival, only committing to a launch "later this year."


Contrary to the leaked staff memos, Samsung Pay, Samsung's own mobile payment system that works with both NFC and MST (the same magnetic swiping technology used by credit cards), will not launch on Aug. 21, but on Sept. 28. It's likely McDonald's confused Samsung Pay's launch date with that of the Galaxy Note 5 and Galaxy S6 Edge+, which did arrive last week. (The payment service launched in South Korea on Aug. 20.)

Samsung is going big with its latest hard drive — like, 16 terabytes big.

The Korean tech giant this week introduced the PM1633a, what it calls the world's largest hard drive, according to Ars Technica UK and Golem.de.

The 2.5-inch solid state drive, targeted at the enterprise market, packs an impressive 15.36TB of storage. To put that in perspective, the largest hard drives made by Seagate and Western Digital top out at 8 to 10TB, Ars noted.


Only…it’s not, if you’re throwing around the perennially popular pictograms using anything besides iOS. I’ll explain, because I can already tell you’re riveted.


To help bridge the digital divide between Americans who have access to the Internet and those who do not, Google will provide free Google Fiber service to some public housing residents, the company said 15/07/15.

Google will roll out the free service to select public and affordable housing projects in the markets where Google Fiber currently operates, including Atlanta, Raleigh-Durham, Nashville, and Kansas City, Missouri. The company said it would also waive the $300 installation fee.

After countless spin-offs and licensed tie-ins, Angry Birds 2 is finally a real thing — and it's coming on July 30. Rovio's got a new website for the game up, complete with a countdown and a newsletter sign-up, but the actual details of its bird-slingshotting puzzle sequel are scant.



While most people are now using their smartphone as their music player on the go, there are still a few who like to have a dedicated device. That’s why Apple has released a new selection of iPods to its online store.



Android M, the next version of Google's mobile operating system that will be launching this fall, will feature built-in visual voicemail support for its dialer function.
