Solu might look like a drinks coaster but don't put your coffee on it; this is a four-inch wide block of curved, wood-encased computer with an edge-to-edge touch screen. Inside is a powerful 2.3GHz processor, battery and Wi-Fi capability. It can be used on its own or paired with a keyboard and a display up to a resolution of 4K. When paired in this way, the Solu acts as an input device instead of a mouse.

I thought it'd be a "fun" project to see what the "El Capitan License" actually says. Cool idea, huh? Kind of like spelunking through a cave that everyone says they’ve been through, but maybe no one really has. What will I find wedged in a wall or lurking in the dark around the next turn?

Valve Software's Steam platform has become the go-to source for gamers focused on the PC. With a huge catalog, constant sales and a consumer-first attitude, the digital store for games has exploded. As of the beginning of 2014, it had topped 75 million users.

But can that success translate into the living room and hardware, two arenas Valve has yet to conquer?

Valve's first round of officially branded Steam Machines will roll out from several manufacturers beginning on Nov. 10. Before that happens, Polygon was able to go hands-on with Alienware's version of the Steam Machine, which comes packed with a quad-core Intel Core i7 processor, a custom-built Nvidia GeForce GTX card and 8 GB of RAM. We also got to test out Steam's unique new controller.

The issue isn't that Marco is successful, there are many app developers who would love to be in the same position. He has earned his time in the spotlight, and it's only natural for him to take advantage of it. Though to state that anyone can simply do the same thing and be successful, is just plain wrong. He has accelerated the race to the bottom for the podcast app category, and he comes bearing a huge following of people who will give him money for nothing in return except for the possibility of further development of Overcast. The average developer isn't being called out by name by Phil Schiller for something negative they have written about Apple. The only thing "indie" about Marco is that he works by himself. He is far removed from the typical experience of app creators, and even if it's deserved, it wouldn't hurt for him to be a little more humble, and realistic.

Intel and Microsoft are teaming with three leading PC makers on a new ad campaign designed to make potential computer buyers more aware of all the things a modern PC can do.

The campaign, with the slogan "PC Does What?" is set to be announced Thursday at a Webcast featuring the companies' top marketing executives, according to sources familiar with the companies' plans. It will feature TV, print and online advertisements, sources said.

Apple's Swift has been available for over a year now, and Apple has promised it will be made available under an Open-Source license by the end of 2015.

That's great, but could I run Swift code on an Android device today?

It's been over three years since the very first Mac went Retina, and we're still waiting for every model to get the upgrade. But this year, the scales started to tip in Retina's favor. We got an all-new Retina MacBook in the spring, and today Apple is killing the 27-inch non-Retina iMac and introducing a new 4K model at the top of the 21.5-inch lineup.

The 4K iMac starts at $1,499 and does for the 21-inch iMac what the 5K version did for the 27-inch iMac a year ago: it gives it a Retina screen and leaves pretty much everything else alone. You do get a handful of nice internal upgrades, including Intel's Broadwell CPUs and GPUs, Thunderbolt 2 support, and faster storage and RAM (all also available on the refreshed non-Retina 21.5-inch iMacs). But for most intents and purposes, this thing is just a 2012-era iMac chassis with a nice sharp screen installed in place of the old 1080p display.

So here's where we're at with the Gear S2: it's a well designed, easy to use smartwatch that makes a good complement to your Android smartphone. If checking notifications, tracking the basics of your physical activity, controlling music, and getting small bits of info are all you want from a smartwatch, the S2 fills all of those needs.

But if you look at smartwatches as an entirely new medium for which developers have yet to fully exploit, the S2 should give you pause. It's entirely possible, likely even, that Samsung ​won't get the developer support it needs to strengthen the S2's platform. Pebble has been able to do that to a limited extent, but history tells us the odds of that happening again are arguably low.

Few people even remember that such a medium as vinyl movies existed, but for a brief, doomed period in the early 1980s, home video was available on CEDs. While CED players were not released to consumers until 1981, the development of the system dates back to the 1960s. The idea was that they could encode sound and video information to a vinyl disc if they could only get the grooves small enough.

The Linux Standard Base (LSB) is a specification that purports to define the services and application-level ABIs that a Linux distribution will provide for use by third-party programs. But some in the Debian project are questioning the value of maintaining LSB compliance - it has become, they say, a considerable amount of work for little measurable benefit.

But Debian's not throwing all of the LSB overboard: we're still firmly standing behind the FHS (version 2.3 through Debian Policy; although 3.0 was released in August this year) and our SysV init scripts mostly conform to LSB VIII.22.{2-8}. But don't get me wrong, this src:lsb upload is an explicit move away from the LSB.

Apple just hired some of Tesla's most important engineers. Do you have to worry about a new competitor?

Important engineers? They have hired people we've fired. We always jokingly call Apple the "Tesla Graveyard." If you don't make it at Tesla, you go work at Apple. I'm not kidding.

Do you take Apple's ambitions seriously?

Did you ever take a look at the Apple Watch? (laughs) No, seriously: It's good that Apple is moving and investing in this direction. But cars are very complex compared to phones or smartwatches. You can't just go to a supplier like Foxconn and say: Build me a car. But for Apple, the car is the next logical thing to finally offer a significant innovation. A new pencil or a bigger iPad alone were not relevant enough.

Yesterday's Windows 10 hardware launch event was without question the best Microsoft in ages - and arguably the tech launch event of the year. Microsoft unveiled its first-ever laptop, showed off an updated Surface Pro 4, and announced a new lineup of phones, all while articulating a confident, aggressive strategy of turning Windows 10 into the underlying software service and platform for virtually everything in your life.

That huge bet might not pay off - Apple and Google are still formidable competitors, and the road back to mobile relevance will be a long one - but it's more vision and purpose than we've seen from Redmond in years. So I sat down with new Microsoft CEO Satya Nadella at the soon-to-open Microsoft flagship store in Manhattan to ask him how he'd changed the entire vibe at Microsoft in the past 18 months, and what he hopes to accomplish in the next 18 months. We also talked about how he plans to keep his Windows OEM partners happy even as Microsoft's Surface Book laptop competes directly with their high-end products, and just how he plans to get back in the phone game.

League of Legends players collectively send millions of messages every day. They're asking friends to duo-queue, suggesting a team comp on the champ select screen, and thanking opponents for a good game. On July 21st of this year (I picked a day at random), players forged 1.7 million new friendships in the game - that's a lot of love! And each time players send a message they trigger a number of operations on the back-end technology that powers Riot chat.

In the previous episode of this series on chat, I discussed the protocol we chose to communicate between client and server: XMPP (Extensible Messaging and Presence Protocol). Today I'll dive into the mechanisms in place on the server-side and the architecture of the infrastructure, and I’ll discuss the work we’ve done to ensure that our servers are scalable and robust. Like the last article, I hope it’ll be interesting to anyone building out chat features to a distributed client base.
