From Cancer Research to Financial Crises, High-Performance Computing is Defining Our Future
Predicting earthquakes. Mapping the human genome. Recreating the “big bang.” Our attempt to unravel the world’s biggest mysteries would be impossible without computers-and with increased access to innovative computing technologies, we’re just beginning to scratch the surface of what can be deciphered. Computing power is growing exponentially. The first supercomputer, a CDC 6600 released in 1964, operated at three million floating-point operations per second. Compare that with today’s supercomputers which operate at 125 quadrillion floating-point operations per second. Despite these advancements, the roadblock to mass-implementation of supercomputers has, to date, been cost-supercomputers require

Move over silicon: Machine learning boom means we need new chips
SILICON has been making our computers work for almost half a century. Whether designed for graphics or number crunching, all information processing is done using a million-strong horde of tiny logic gates made from element number 14. But silicon’s time may soon be up. Moore’s law - the prophecy which dictates that the number of silicon transistors on microprocessors doubles every two years - is grinding to a halt because there is a limit to how many can be squeezed on a chip. The machine-learning boom is another problem. The amount of energy silicon-based computers use is set to soar as they crunch more of the massive data sets that algorithms in this field require.

Cortana: The spy in Windows 10
When I first saw Mr. Spock talking to the Enterprise’s computer, I thought it was so cool. I still do. But the more I look at Cortana, Windows 10’s inherent virtual assistant, the more creeped out I get. Let’s start with Cortana’s fundamental lust for your data. When it’s working as your virtual assistant it’s collecting your every keystroke and spoken syllable. It does this so it can be more helpful to you. If you don’t like that, well, you’ve got more problems than just Cortana. Google Now and Apple Siri do the same things. And it’s not just virtual assistants; every cloud-based software as a service (SaaS) does this to one degree or another - Google Docs, Office 365, whatever. But Cortana

Don't go for the cheapest option when you're buying a computer - here's why
It's tempting to go with the cheapest option when it comes to buying expensive computers that have different models and pricing options. You might ask yourself if you really need the extra horsepower of a more expensive laptop if all you'll be doing

Do this to quickly speed up your internet connection
Just to be be clear: resetting your router is different from restarting your router. A router reset will allow you to set it from scratch where it will work at optimal levels. Do this whenever you feel you're having issues with your network or after you've upgraded your internet speed. It's also the only way you can re-gain access to a router's web interface once you've forgotten the password (the password will then be restored to the default password.) When you reset the router you will loose all current network settings, like the name of the Wi-Fi network, its password, etc. If you want to retain the current network settings, you should first log into the router's web interface and save the

Linux Mint 18: The best desktop -- period
I've been using Linux desktops since the leading desktop front-end was Bash. Things have changed in those 25 years. Today, the best Linux desktop is the latest version of Linux Mint: Linux Mint 18 Sarah with the Cinnamon 3.0 interface. Indeed, from where I sit, it's not only the best Linux desktop, it's the best desktop operating system -- period. Many of you, for example, are struggling with the question of whether to "upgrade" to Windows 10. Many of you feel -- with some reason -- you're being forced to move from Windows 7 to Windows 10. Others are now realizing that Microsoft seems to be changing Windows from a purchase model to a subscription model. If you really want to "own" your operating

Don't bother trying to remember all of your passwords - use this simple trick instead
Passwords are inherently insecure. Any password easy enough for you to remember is too short or simple to be effectively secure, whereas any password long and complex enough to be secure (and of course, unique per website) is too long and complex to remember. Yet, we use passwords everywhere. For security reasons, you need a long, complex, unique password for every app and website you log into. Passwords have to be long so it takes longer for a computer to guess it. It gets more and more difficult to guess a string of characters for each character you add. Passwords have to be complex so they don't appear in dictionaries or rainbow tables. Passwords also have to be unique so if you lose your
