For less money that it takes to\u003cbr\u003estop at a drive-through, it's possible to buy the top-end RPi model. (Granted,\u003cbr\u003eI have three teenagers, so the drive-through is expensive.) The Raspberry Pi is as\u003cbr\u003eopen as the manufacturer can make it, has huge community support, and its\u003cbr\u003esoftware isn't backed by a huge corporation with mysterious motivations\u003cbr\u003e(cough, Android, cough). It's just a cool little ARM device that runs\u003cbr\u003eLinux. This month, we focus on the Raspberry Pi. The drive-through is\u003cbr\u003eoptional.\u003cbr\u003e\u003cbr\u003eDave Taylor doesn't work directly with a Raspberry Pi this month, but his\u003cbr\u003econtinuing series on scripting a Cribbage game\u003cbr\u003ecertainly will work on an RPi. Even if you're not a Cribbage fan, Dave's scripting lessons are\u003cbr\u003einfinitely useful for learning. Reuven M. Lerner teaches a thing or two\u003cbr\u003ethis month as well—specifically in regard to running background tasks in\u003cbr\u003eyour Web applications. Running things in the background can make a\u003cbr\u003emonstrous Web application perform much more quickly from the end user's\u003cbr\u003eperspective. Reuven shows how with Sidekiq.\u003cbr\u003e\u003cbr\u003eKyle Rankin, who first interested me in Raspberry Pi devices, talks about\u003cbr\u003eredundancy this month. What's better than a Raspberry Pi? Redundant\u003cbr\u003epies—or Pis, rather. If you want to bolster your RPi reliability or \u003cbr\u003ejust want an inexpensive platform to learn clustering, Kyle walks \u003cbr\u003ethrough the process. I've been writing about my Raspberry Pi\u003cbr\u003eadventures off and on for the past six months, so this month, I decided to\u003cbr\u003efocus on an issue that is near and dear to my heart: RSS. If the Google\u003cbr\u003eReader shutdown in July has you worried about how you'll browse the Web,\u003cbr\u003eperhaps my column will help. I'm past panic mode, and I've been able to\u003cbr\u003ewean myself off Google Reader altogether.\u003cbr\u003e\u003cbr\u003eI'm probably not the only Linux Journal reader who has a full\u003cbr\u003evirtualization system with iSCSI SAN\/NAS storage in my basement.\u003cbr\u003eUnfortunately, along with that nerdy power comes a big electricity bill.\u003cbr\u003eBrian Trapp describes the other end of that spectrum with his article on\u003cbr\u003ecreating the perfect home server—with a Raspberry Pi. There are plenty of\u003cbr\u003ereasons powering your Linux server infrastructure with a cell-phone charger\u003cbr\u003eis awesome, and Brian explains how. If you want to add IPv6 to the mix,\u003cbr\u003eIgor Partola follows up with an article on creating an IPv6 router on your\u003cbr\u003enetwork, even if your ISP doesn't support it!\u003cbr\u003e\u003cbr\u003eI realize all my \"servers in the basement\" stuff is almost\u003cbr\u003ecliché when talking about Linux users. To be fair, I didn't say it was my mom's\u003cbr\u003ebasement. Still, Jonathan Brogdon's article on controlling stage lighting\u003cbr\u003ewith a Raspberry Pi is a great way to avoid our basement-dwelling\u003cbr\u003estereotype. Jonathan literally puts RPi in the spotlight with his\u003cbr\u003ehardware\/software combination for controlling external lighting. It's a\u003cbr\u003ereal-world solution and really cool to read about.\u003cbr\u003e\u003cbr\u003eThe coming shutdown of Google Reader has made all of us think a little\u003cbr\u003eharder about the dangers of cloud computing. At the very least, it's forced\u003cbr\u003eus to think about trusting cloud-based services we don't directly control.\u003cbr\u003eDiana Marina Cooper talks about the other end of the cloud—specifically as\u003cbr\u003eit relates to open-source compliance. How does the GPL relate to a world of\u003cbr\u003e\"Software as a Service\"? If the cloud obfuscates the software and the code,\u003cbr\u003ewhat does that mean with regards to FOSS? Diana takes a serious look at a\u003cbr\u003eproblem not many of us consider.\u003cbr\u003e\u003cbr\u003eDo you have a Raspberry Pi, and are you looking for something to do with it? Do\u003cbr\u003eyou already have a rack of clustered-RPi devices in your basement, and\u003cbr\u003eare you looking for tips on optimization? Regardless of your immersion level\u003cbr\u003einto the Pi, this issue should prove useful and entertaining. Even if you\u003cbr\u003ehave no interest in the Raspberry Pi, this issue is full of the same\u003cbr\u003etech tips and Linux news you're used to seeing. This issue was incredibly \u003cbr\u003efun to put together, and we hope you enjoy it as much as we did.","brand":"Linux Journal","offers":[{"title":"Default Title","offer_id":47071401541872,"sku":"2940016583419","price":2.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/2940016583419_p0.jpg?v=1763638277","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/2940016583419","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
