Transformers and Hard Drives

Believe it or not, you could never own and use your hard drive if society had not invented and made use of the transformer. Transformers work when you’re dealing in the realms of AC or alternating current, the kind of current generally used by power plants to create and distribute electrical energy. Let’s take a closer look.

transformer2Transformers work in conjunction with the concept of mutual induction, which states that two or more coils of wire can be placed in such a way that changing the magnetic field created by one induces a voltage in the other. That means if you have two mutually inductive coils and one is energized with AC, an AC voltage will be created in the other coil. The device by which this is done is called a transformer.

Transformers are used not only to create voltage in new coils but to adjust the voltage in the second coil in whatever way is convenient. The voltage produced in the secondary coil is always equal to the AC voltage across the powered coil multiplied by the ratio of secondary coil turns to primary coil turns. If the secondary coil is powering a load (like a light or a motor), the current through the secondary coil will be the opposite and the primary coil current multiplied by the ratio of the primary to secondary turns will apply. Often this process is explained with a mechanical analogy in which torque and speed are meant to represent voltage and current, respectively:

Imagine that a transformer is to coils with different currents and voltages as a geartrain is to gears of different sizes moving at different speeds. Speed multiplication gear trains steps torque down and speed up. Step-down transformers step voltage down and current up.

This might be a good time to be reminded of the difference between voltage and current. Voltage is the difference in charge between two points. Current is the rate at which charge is flowing. If charge were water, voltage would be the water pressure and current would be the rate at which the water flowed.

transformer 3So say the primary coil has less turns than the secondary coil; the transformer will then step up the voltage from the source level to a higher level at the load.

Transformers can step only AC voltage up or down; the process doesn’t work with direct currents. If you’re trying to transmit electrical power over long distances, it’s much more efficient to do so with stepped-up voltages and stepped-down currents because you can use smaller-diameter wire with less resistive power losses. That’s why alternating current is almost always used by power providers for easier shipping to industry, business, or private consumer use.

That means that the factory that made your hard drive used AC power that was able to be carried to the facility through use of a transformer. The same goes for the electricity that you use to run your computer in the first place. Without transformers, your hard drive would cease to be.

Money Management Apps that will Change Your Life

Managing your income and expenses can be overwhelming, especially if you have a variety of bills and sources of income coming in on different dates. However, any struggling self-financier can be comforted by the five most blessed words of the 21st century: “There’s an app for that.” Here is a list of the best money management apps that can organize your life and save you some unnecessary stress.


This app is widely used and has enjoyed high reviews from users with a variety of incomes. It allows you to manage your income and spending so that you save more successfully by more consciously following a budget. It can sync up all of your accounts from bank accounts and mutual funds to 401(k) or IRA accounts, allowing you to get a comprehensive look at your budgetary needs.

Mint sends you updates that remind you of past transactions and show you how you’ve been using your accounts. You can also see overviews of your account totals, monthly budget, credit score (you can get one free with your sign up), categories of spending, and alerts regarding when you went over budget. It can also tell you when your balance is dangerously low, a marker which you can set to your personal taste.

Basically, Mint logs your cash flow in real time and even analyzes your spending habits, allowing you to take note of areas where you can potentially save more money.

good budget app2. GoodBudget

This app is slightly less comprehensive than Mint, but great for people who simply want to create a budget based on their cash flow and attribute certain amounts of money to certain categories.

Spending areas are separated into different “envelopes” which the user can create to his or her personal taste. Recurring budgets can be monthly, weekly, semi-monthly or biweekly based on personalized starting dates. The app is said to be optimal for people whose pay schedules vary. Freelancers and the like can opt into the “irregular” option that allows less routine spending to be tracked accordingly.

expense manager3. Expense Manager

Ideal for vacationers splitting funds, the Expense Manager app allows users to add expenses and fill in details about the amount, payee and payment category. Pre-written vendors and category terms can be selected for easy set-up. Expense Manager also has an “auto fill” feature for even easier inputs; terms for commonly used expenses like “gas” and “eating out” can be only a tap or two away.

That’s not all for this app’s bells and whistles; it also has multiple account support, photo-storing capability, and home screen widgets.

Some complaints have been made regarding the app’s design, but functions can be googled and found if the user has any trouble. In addition, the app is free assuming the user is open to it being ad supported. It’s only $5.00 without ads, which may be a worthy expenditure for those who find ads a headache.

So there you have it, there truly are ways to organize your finances and keep track of where you’re spending and how you can save.

Protect Your Privacy by Avoiding Malware

The last few years have brought heightened attention to the necessity of cybersecurity and important precautions to protect internet users, but unfortunately hackers seem to develop new attack strategies as fast as people catch up with the last ones. Here’s what internet users need to understand today (though who knows what new issues tomorrow will bring).

There’s a variety of types of malware (short for malicious software), which is any program that runs on a computer without a user’s knowledge and performs predetermined features that cause harm.

Adware, for example, resides on a computer without a user’s knowledge and displays pop-up advertisements. Computers effected by adware run the risk of constantly being disturbed by annoying ads

A virus is a program that is programmed to spread itself across files on a single computer or even across computers using the internet.  Often computer hackers create viruses just to mess with people, or to see how far they can get it to spread before it’s contained. If the virus does spread far, it’s a source of pride and bragging rights for the creator.

A worm is like a virus but it spreads itself around a network by creating copies of itself as it spreads and might be able to change its profile to avoid detection. One of the most famous worms ever created was developed by the US and Israeli governments. They infected an Iranian nuclear power plant with the worm so that a variety of mechanical issues would slow down Iranian nuclear progress without seeming like there was any outside involvement. The point was to just make the disruptions seem like bad luck. Neither the US or Israeli government has confirmed they were responsible for the worm.

trojanA Trojan is named for the infamous horse of Greek mythology because it takes on the appearance of something benign and, once downloaded onto your computer, enacts harm to computer by erasing your hard disk or deleting all your image files. It can also gather information and send it to its creator.

Spyware is a kind of software that secretly resides within a computer’s programs and sends information to its programmer. This information could span from browser history to passwords and login information. Often spyware just acts as a way to release pop ups onto someone’ s computer, but they can be really eulaharmful when they’re used to hack into people’s online bank accounts.

Finally, a cookie (which doesn’t really count as malware) is a small data file used by websites to store information on your computer, whether it’s a shoppingwebsite that wants to identify items you’ve looked at or a website that you’ve given permission to store your password.
It is much more likely that these various forms of malware will gain access to your computer through your own error; this happens more often than malware somehow downloading itself onto a computer. That means that the best mode of prevention is for users to be careful and always read the EULA before downloading any program from the internet.


The Debate Around Data Encryption

Whether your data exists in the cloud or on a hard drive, investing in its encryption has probably crossed your mind. As terrorism continues to scar the global climate, the ability of consumers to encrypt their data has become a matter of political debate; some officials believe that consumer encryption presents a substantial threat to national security, while privacy advocates strive to further limit the ability of the government to pry through citizens’ personal information without a warrant.

paris attacksThe tragic attacks on Paris last Friday have only further fueled the topic; CIA director John Brennan stated that he hoped the violence would serve as “a wakeup call” to those who oppose government surveillance in favor of personal privacy. He continued, “There are a lot of technological capabilities that are available right now that make it exceptionally difficult both technically as well as legally for intelligence securities to have the insight that they need to uncover [important public safety information].”

Brennan blamed Edward Snowden’s disclosures of the National Security Agency’s bulk data collection for what he believes to be a recently heightened insecurity within the U.S. and global climates: “There have been some policy and legal and other actions that make our ability, collectively, internationally, to find these terrorists much more challenging.”

FBI director James Comey also claims that encryption is a national security threat, claiming that it enables criminals to “go dark.”

This debate gains speed as the 2016 primary debates continue to unfold, forcing candidates to identify their positions in a very new-age problem.

Most of the Republican candidates have already taken a side and let it be known; the common consensus among G.O.P. members is that a consumer’s right to data encryption is trumped by the societal value of government surveillance.

Kentucky Senator Rand Paul is the exception to the rule, as he stated last week that governments should have to require warrants to access people’s communications. His statements responding directly to encryption are pending (a relevant distinction to make given that encrypted information is extremely difficult to access, even with a warrant).

Democratic candidates have slightly more variant opinions. Vermont Senator Bernie Sanders has been outspoken regarding his opposition to government surveillance and voiced his intention to shut down the NSA’s surveillance program at the first Democratic primary debate.

hillary clintonFormer Secretary of State Hillary Clinton has a less clearly outlined opinion; she supported the controversial PATRIOT Act in 2001 and more recently claimed that the recently passed Cybersecurity Information Sharing Act (CISA) did not adequately encourage tech companies to share information with the US government. Conversely, she endorsed the USA Freedom Act, which would end the NSA’s bulk data collection program, and applauded its ability “to protect our security and civil liberties.”

Clinton freely admits that the encryption/cybersecurity issue is “a classic hard choice.”

“I would be the first to say I don’t have an answer,” she said. “I think there are really strong, legitimate arguments on both sides.”

The issue may boil down to the amount of trust US citizens have in their government; they have to guess whether the government will protect them or oppress them with the power of their private information.

Google Remains Committed to Artificial Intelligence and Machine Learning


Google CEO Sundar Pichai recently released his first earnings call, revealing a solid third quarter.  As the call drew to a close, some investors asked Pichai and Google CFO Ruth Porat about the company’s progress with machine learning.

Pichai responded that the development of artificial intelligence and machine learning are among Google’s top priorities.

Google has been devoting time and resources to the development of machine learning since the beginning of the “Google Brain” project in 2011. Google Brain is one among multiple simultaneous and independent Google-funded projects aimed at cracking the problem of artificial intelligence.

“The progress, particularly in the last two years, has been pretty dramatic” reported Pichai. “We’re thoughtfully applying it across all of our products, be it search, be it ads, be it YouTube and Play.”


One can’t help but be reminded of Google X’s Self-Driving Car (SDC), which has been raising neck hairs since lead engineer Sebastian Thrun led the award-winning project to fruition in 2005. In 2014, Google created a new SDC prototype that functions without a steering wheel or pedals. This newest model has undergone on-road testing in the San Francisco Bay Area since 2015. The cars are to be made available to the public starting in 2020.

In light of the unprecedented technological advances made possible by developments in AI, many are wondering exactly what machine learning is and why it is useful.

Charles King, principal analyst for Pund-IT, has the answer: “In essence, what machine learning provides are ways for computerized processes to learn as they go, thus improving performance over time and through experience. As a result, ML could be applied in virtually any industrial situation, from enhancing the time and results of product design processes to monitoring and maintaining complex machines.”

Although ML has great potential, it also presents major challenges in terms of the level of processing power it requires. For example, in 2012 16,000 computer processors were required for Google Brain to teach itself how to recognize cats on the internet.

google brain cat

That said, the prevalence of utilities such as GPS and speech-recognition for smart phones speaks to the potential payoff for the winners of the AI game. ML tends to lead to products that, once obtained, consumers hate to go without.

Take facial recognition software for example. Social networking sites like Facebook make uploading and organizing photos of friends easier by using programs that can actually recognize who is in each photo and sort the photos accordingly.

There are the occasional hilarious mix-ups of course, and then there was the not-so-hilarious instance in which a Google Photos app labeled an African-American woman as a gorilla. Google was quick to apologize, and a spokesman reported, “There is still clearly a lot of work to do with automatic image labeling, and we’re looking at how we can prevent these types of mistakes from happening in the future.”

Here’s to hoping that Google’s Self-Driving Cars don’t suffer from these kinds of hiccups, seeing as they’re already on the road.

Data Recovery: All That It Covers

Data is the modern Heart of any organization in the current scenario- the heart fails, the organization is history. And, with the variance in businesses and its expansion, the load of the data has never seen such a muddling phase of time – of its collation and management being of almost prime importance to a business. Also, is for the fact that the privacy laws regarding the IT industry have never being tweaked to be so strict and in requirement of strict compliance. The legal issue making it only an inescapable den to pass through! Moreover, the data is your Bible, your organizations breather, ensuring the day-to-day work and functions of the organization get its requisite and constant fuel to perform and deliver.

Now, that the data is being mentioned in terms of its sheer quantity, can data loss be overlooked? It could be either imagined by you as a piece of jewelry being lost in a stack of bundles, or a whole bundle gone missing from the place of your acquaintance. Choose whichever is convenient and you could relate to the panic and the standstill-like situation that follows. The effects of Data loss is pretty much the same- in fact, even more intense in some cases, without exaggeration.

Data, being now entirely in the zone of the digital spread, is not like the bygone era one- being trapped in the physical pages of a big fat book. So, as much as this has been good news for the quantum part of it, but a loss can affect it just the opposite. The pros with its cons, and thorns! There can be quite a many reasons that can lead to data loss. Some of the main three reasons commonly observed are:

  1. This is due to the failure in the Operating System, the parent of the data storage process. This could include the hard disk drive crash, accidental damage, or even as careless ones as accidental deletion! The accidental deletion becomes an issue of mention, as it’s not about accidentally choosing the file and accidentally hitting the delete button. That wouldn’t be possible even by a restless kid, eh! It is about trying to replace one set of data with another in another disk, resulting in the catastrophe!
  2. The other most common scenario that is noticed is in case of data loss is a disk level failure. This could commonly include things like compromised file system or disk partition, or even a hard disk failure. Either of the causes makes the chances of data recovery to a minimal.
  3. In the third most common one is a bit ore strange- it is about having deleted the file from a storage medium. This is basically like the content of the deleted files are not removed from the drive, but very peculiarly their itinerary or the reference s to them in the directory hierarchy are removed. This leads to a major danger of being overwritten by some other content, now that a part of the content being gone!

Choice Of Right And Latest Hardware Can Render Several Benefits

Since the computing devices are going to serve their owners for several years and even decades, it is best to choose ideal ones.

Lost Data Can Be Retrieved By Calling In The Experts In Action

When the files on the hard disk are being regularly used, there are possibilities for them to go corrupted. There are many ways in which such data loss can happen. For instance, the users may have been browsing when a virus, worm or the Trojan would have gotten into the disk. This would corrupt the files and the folders. Once corrupted, either the files may not show up or even if shown in the folders, they would become totally inaccessible.

hardrive1Even if there are liquid spills on the computing devices, there are chances that the droplets get into the hard drives and harm the data completely. There are so many other reasons for the files to get lost, such as in the case of accidental deletion. When the users get to press shift that is followed by delete key, then the files would get lost permanently, at least in their perception.

However, with the experts rendering hard drive recovery service, it is possible for them to retrieve even these data in the proper manner. Even though the persons may use shift and delete keys to ensure that they do not have the deleted files go to the recycle bin, these can be recovered with the right software tools and the knowledge of how best to handle them. The hard drives may also be affected by the power surges or the drops.

Data is vital:

Regardless of whether the entities are individuals or companies, they procure the computer and use the same to manage their data. With the right management information systems, the companies can be taken to different levels of the commercial activities. So many transactions are captured digitally and will be stored in the computers’ hard drive or other memory spaces that the users instruct their systems.

When the data is lost to the various circumstances, then the persons would be in huge trouble in managing the various activities that they are involved in. Therefore, it is necessary for the persons to not get disheartened about the data based accidents. To ensure that the show continues without a break, it is necessary for them to recover the data and store them back to where they belong.

harddrive2Recovery and restoration:

There are various data recovery services that are provided to them by the experts who are aware of the processes and have tools as well. It is possible for them to even recover the deleted files that are not present in any of the areas inside the system. However, one would have to realize that hundred per cent of data cannot be restored and it can be done only once to get back the files. There are two ways of data recovery, which could be logical or physical in nature, both of which can be done by those who have enough experience and expertise in dealing with such contingencies. With the right amount of knowledge and the efficiency of the tools administered, it is easy for the persons to get back their data.
