Free and open source software enables the world as we know it in 2019. From Web servers to kiosks to the big data algorithms mining your Facebook feed, nearly every computer system you interact with runs, at least in part, on free software. And in the larger tech industry, free software has given rise to a galaxy of startups and enabled the largest software acquisition in the history of the world.
Free software is a gift, a gift that made the world as we know it possible. And from the start, it seemed like an astounding gift to give. So astounding in fact that it initially made businesses unaccustomed to this kind of generosity uncomfortable. These companies weren’t unwilling to use free software, it was simply

Best G-SYNC Monitors for Gaming

Got a NVIDIA graphics card in your computer? You’ll want to take a closer look at a G-SYNC monitor if you want a better gaming experience. Recently, prices have dropped on G-SYNC monitors as more competition has entered the market so you’re no longer having to pay a significant premium for the tech.
Now, it’s worth noting that NVIDIA has enabled adaptive sync with certain FreeSync monitors, but the list of supported monitors isn’t very lengthy. If you want a seamless solution to pair with your NVIDIA GPU, you’ll want to invest into a G-SYNC monitor.

It’s possible to build a Turing machine within Magic: The Gathering

That makes it the most computationally complex real-world game yet known. (credit: Gordon Chibroski/Portland Press Herald/Getty Images)
Consider this hypothetical scenario: Bob and Alice are playing a game of Magic: The Gathering. It’s normal game play at first, as, say, Filigree robots from Kaladesh face off against werewolves and vampires from Innistrad. But then Alice draws just the right card from her customized deck, and suddenly Bob finds himself caught in the equivalent of a Turing machine, the famed abstract device that can simulate any computer algorithm. Thanks to the peculiarities of the rules of Magic, Bob can now only finish the game when he meets whatever condition Alice has programmed her in-game algorithm to accomplish—for example, to find a

How to Set Up an IMAX Enhanced Sound System

Today’s home entertainment systems offer incredible fidelity to AV enthusiasts. With the advent of UHD video and 3D immersive sound, cinematic viewing experiences that used to be exclusive to commercial theaters are now available in your living room. IMAX Enhanced takes this concept to the next level, bringing the IMAX theatrical experience home using optimized content and certified AV gear.
There’s a visual and an audio aspect to the IMAX Enhanced Program. Movies are delivered in 4K UHD with HDR using a proprietary mastering process that optimizes imagery for presentation on today’s big-screen TVs and home theater projectors. Meanwhile, on the sound side, a special variant of the DTS:X codec is used to help recreate the IMAX theatrical experience, a 3D immersive audio experience that can deliver the full range and dynamics of an IMAX theatrical presentation.
What’s an IMAX Enhanced Sound System?
In this article, we’ll look at how to set up
