A few weeks ago you had a chance to ask author, entrepreneur, and software developer Jeff Atwood about founding Stack Overflow and the Stack Exchange Network, as well as his new endeavor, the Discourse open-source discussion platform. Below you will find his answers to your questions.

No, working your company's trade show or conference booth isn't your job. But sooner or later, an awful lot of people (including me) get tagged for booth duty whether we want it or not. Fine. At least we can learn a little about how to do it well, which is why Andy Saks, of Spark Presentations, is offering us some useful tips on how to do well at trade shoms and conferences.

While Andy's focus is on corporate displays and presentations, everything he says also applies to FOSS projects that exhibit at anything from regional Linux conferences to multinational expos like OSCON and LINUXCON. And one last thought before we turn this over to Andy, who we recorded from Skype at an extremely low frame rate to make this a narrated slide show (with accompanying transcript, as usual): If you're working in a typical corporation, trade shows are often your best way to meet your own company's executives, espcially at casual after-show gatherings. You might also meet execs from other companies and be open to conversations about changing jobs, but this is not something you want to talk about with your bosses or their bosses, but is best kept quiet until or unless you have a firm offer in hand.

Brady Forrest is co-author of The Hardware Startup: Building Your Product, Business, and Brand. He has extensive experience building both products and startups, including staffing, financing, and marketing. If you are thinking or dreaming about doing a startup, you should not only watch the video to "meet" Brady, but read the transcript for more info than the video covers.

More From Tim O'Reilly about the 'WTF?!' Economy (Video) On August 12 we ran two videos of Tim O'Reilly talking with Slashdot's Tim Lord about changes in how we work, what jobs we do, and who profits from advances in labor-saving technology. Tim (O'Reilly, that is) had written an article titled, The WTF Economy, which contained this paragraph:

"What do on-demand services, AI, and the $15 minimum wage movement have in common? They are telling us, loud and clear, that we’re in for massive changes in work, business, and the economy."

We're seeing a shift from cabs to Uber, but what about the big shift when human drivers get replaced by artificial intelligence? Ditto airplane pilots, burger flippers, and some physicians. WTF? Exactly. Once again we have a main video and a second one available only in Flash (sorry about that), along with a text transcript that covers both videos. Good thought-provoking material, even if you think you're so special that no machine could possibly replace you.

An anonymous reader writes Sony has done a lot of aggressive anti-piracy work in their time, which makes it that much funnier that pirated ebooks were found on their servers from the 2014 hacks that just went on to WikiLeaks. Better yet, the pirated books are educational books about hacking called "Inside Cyber Warfare" and "Hacking the Next Generation" from O'Reilly publishers.

Michael Ross writes In recent years, JavaScript has enjoyed a dramatic renaissance as it has been transformed from a browser scripting tool primarily used for special effects and form validation on web pages, to a substantial client-side programming language. Similarly, on the server side, after years as the target of criticism, the PHP computer programming language is seeing a revival, partly due to the addition of new capabilities, such as namespaces, traits, generators, closures, and components, among other improvements. PHP enthusiasts and detractors alike can learn more about these changes from the book Modern PHP: New Features and Good Practices, authored by Josh Lockhart. Keep reading for the rest of Michael's review.

Presto Vivace writes: O'Reilly Radar has an article about how ubiquitous tracking and collection of data will fundamentally change how we live. Quoting: "This timeline — beginning for newborns at Year Zero — will be so intrinsic to life that it will quickly be taken for granted. Those without a timeline will be at a huge disadvantage. Those with a good one will have the tricks of a modern mentalist: perfect recall, suggestions for how to curry favor, ease maintaining friendships and influencing strangers, unthinkably higher Dunbar numbers — now, every interaction has a history. This isn’t just about lifelogging health data, like your Fitbit or Jawbone. It isn’t about financial data, like Mint. It isn’t just your social graph or photo feed. It isn’t about commuting data like Waze or Maps. It’s about all of these, together, along with the tools and user interfaces and agents to make sense of it."

M-Saunders writes: How do we take advantage of big data without putting our privacy at risk? Should everyone be able to code? And how much life is still in the market for printed books and publications? Linux Voice put these questions to Tim O'Reilly, the founder of O'Reilly media, and the man who helped to popularize the terms Open Source and Web 2.0. ("Should everybody be a professional coder? No way. Should everybody be able to do more than just use a GUI? Absolutely. Should people be able to automate operations of a computer? Absolutely.") Despite the amount of "free" (or advert-supported) content out there, O'Reilly still believes there's plenty of money to be made: "I think that the willingness of people to pay for things that delight them will not go away."

Threatpost reports: Heatmiser, a U.K.-based manufacturer of digital thermostats, is contacting its customers today about a series of security issues that could expose a Wi-Fi-connected version of its product to takeover. Andrew Tierney, a "reverse-engineer by night," whose specialty is digging up bugs in embedded systems wrote on his blog, that he initially read about vulnerabilities in another one of the company's products, NetMonitor, and decided to poke around its product line further. This led him to discover a slew of issues in the company's Wi-Fi-enabled thermostats running firmware version 1.2. The issues range from simple security missteps to critical oversights.For example, when users go to connect the thermostat via a Windows utility, it uses default web credentials and PINs. ...Elsewhere, the thermostat leaks Wi-Fi credentials, like its password, username, Service Set Identifier (SSID) and so on, when its logged in. Related: O'Reilly Radar has an interesting conversation about what companies will vie for control of the internet-of-things ecosystem.

An anonymous reader writes Forget about some kid engineering a virulent microbe in their bedroom. As the assistant director of the Maurice Kanbar Center for Biomedical Engineering, Oliver Medvedik, puts it, "It's extremely difficult to 'improve' on the lethality of nature. The pathogens that already exist are more legitimate cause for worry.” If anything, you're better off putting energy into wrenching away your desire for McDonalds, and making sure the government doesn't impose draconian laws about DIY-bio. Here's a look at the grassroots future of biohacking and the problems with government overreach.

Today's videos are parts five and six of our casual interview with Tim O'Reilly, founder of O'Reilly Media and one of the most influential open source boosters around. (You supplied the questions. He supplied the answers.) We had a lot more to say about Tim Tuesday when we ran parts one and two of our video interview with him. Yesterday we ran parts three and four. (Today's alternate Video Links: Video 5 ~ Video 6.)

Today's videos are parts three and four of our casual interview with Tim O'Reilly, founder of O'Reilly Media and one of the most influential open source boosters around. (You supplied the questions. He supplied the answers.) We had a lot more to say about Tim yesterday when we ran parts one and two of our video interview with him. (Today's alternate Video Links: Video 3 ~ Video 4; transcript covers both videos.)

Today's interview guest is literally a household name: If you look at the shelves in nearly any programmer's house, developer shop or hackerspace, you'll probably see a stretch of books from O'Reilly Media (or O'Reilly & Associates, depending on how old the books are). Tim O'Reilly started out publishing a few technical manuals in the late '70s, branching from there into well-received technical reference and instructional books, notably ones covering open source languages and operating systems (how many people learned to install and run a new OS from Matt Walsh's Running Linux?), but neither Tim O'Reilly nor the company has gotten stuck in one place for long. As a publisher, he was early to make electronic editions available, in step with the increasing capabilities of electronic readers. Make Magazine (later spun off as part of Maker Media, which also produces Maker Faires around the world) started as an O'Reilly project; the company's conferences like OSCON, Fluent, and this year's Solid are just as much a manifestation of O'Reilly's proclivity for spreading knowledge as the books are, and those are only part of the picture, being joined with seminars, video presentations, and more. Tim O'Reilly is often hailed as a futurist and an activist (he was an early proponent of 3-D printing and hardware hacking, and a loud voice for patent reform) and he's got his eye on trends from global (how the Internet functions) to more personal -- like ways that physical goods can be produced, customized, and networked. So please go ahead and ask O'Reilly about what it's been like to be a publisher of paper books in an ever-more electronic world, as well as a visionary in the world of DIY and fabrication, or anything else on your mind. As usual, ask as many questions as you'd like, but please, one per post.

An anonymous reader writes "There is certainly no shortage of stories about AI systems that include the saying, 'like the brain'. This article takes a critical look at those claims and just what 'like the brain' means. The conclusion: while not a lie, the catch-phrase isn't very informative and may not mean much given our lack of understanding on how the brain works. From the article: 'Surely these claims can't all be true? After all, the brain is an incredibly complex and specific structure, forged in the relentless pressure of millions of years of evolution to be organized just so. We may have a lot of outstanding questions about how it works, but work a certain way it must. But here's the thing: this "like the brain" label usually isn't a lie — it's just not very informative. There are many ways a system can be like the brain, but only a fraction of these will prove important. We know so much that is true about the brain, but the defining issue in theoretical neuroscience today is, simply put, we don't know what matters when it comes to understanding how the brain computes. The debate is wide open, with plausible guesses about the fundamental unit, ranging from quantum phenomena all the way to regions spanning millimeters of brain tissue.'"

An anonymous reader writes "Looking to a day when modern infrastructure is network addressable, Glen Martin considers that, lacking only requisite content and relatively simple augmentation, most of what we need for smart cities already exists: 'Using smart phones, pedestrians could "wake up" the objects by accessing codes generally used by the city to identify street items that required repair. Each bit of infrastructure would make some kind of declamatory statement — sometimes gracious and welcoming, sometimes didactic, sometimes peevish. The "interlocutor" would then respond, and a brief exchange would ensue. The object would then invite the passerby to return for more conversation.'"

An anonymous reader writes "Speculating the future of human computer interaction, Tim O'Reilly contemplates how humans and things cooperate differently when things get smarter. He says, '[S]o many of the most interesting applications of the Internet of Things involve new ways of thinking about how humans and things cooperate differently when the things get smarter. It really ought to be called the Internet of Things and Humans ... is Uber an #IoT application? Most people would say it is not; it’s just a pair of smartphone apps connecting a passenger and driver. But imagine for a moment the consumer end of the Uber app as it is today, and on the other end, a self-driving car. You would immediately see that as #IoT. ... Long before we get to fully autonomous devices, there are many “halfway house” applications that are really Internet of Things applications in waiting, which use humans for one or more parts of the entire system. When you understand that the general pattern of #IoTH applications is not just sensor + network + actuator but various combinations of human + network + actuator or sensor + network, you will broaden the possibilities for interfaces and business models."

Michael Ross (599789) writes "Web designers and developers nowadays are familiar with the critical decision they face each time before building an application intended for mobile devices: whether to target a particular device operating system (e.g., iOS) and create the app using the language dictated by the OS (e.g., Objective-C), or try to build an operating system-agnostic app that runs on any device equipped with a modern web browser (primarily using HTML5, CSS3, and JavaScript), or try to do a combination of both (using a library such as PhoneGap). The second option offers many advantages, and is the approach explored in the book Mobile HTML5, authored by Estelle Weyl, an experienced front-end developer." Keep reading for the rest of Michael's review.

theodp (442580) writes "Over at Microsoft on the Issues, Microsoft continues to lament the computer programming skills gap of American kids, while simultaneously lobbying for more H-1B visas to fill that gap. Saying that states must do more to 'help students gain critical 21st century skills,' Microsoft credits itself and partner Code.org for getting 30,606,732 students to experience coding through the Hour of Code, claiming that K-12 kids have 'written 1,332,784,839 lines of code' (i.e., dragged-and-dropped puzzle pieces), So, if it's concerned about helping students gain programming skills, shouldn't Microsoft be donating fully-functional desktop versions of MS-Office to schools, which would allow kids to use Visual Basic for Applications (VBA)? While Microsoft's pledge to give 12 million copies of its Office software to schools was heralded by the White House and the press, a review of the 'fine print' at Microsoft suggests it's actually the online VBA-free version of Office 365 Education that the kids will be getting, unless their schools qualify for the Student Advantage program by purchasing Office for the faculty and staff. Since Microsoft supported President Obama's call for kids to 'Don't Just Play on Your Phone, Program It', shouldn't it give kids the chance to program MS-Office, too?"

An anonymous reader writes "This article at O'Reilly Programming suggests that PHP, a language known as much for its weaknesses as its strengths, has made steady progress over the past few years in fixing its problems. From the article: 'A few years ago, PHP had several large frameworks (e.g. CakePHP, CodeIgniter, and so on). Each framework was an island and provided its own implementation of features commonly found in other frameworks. Unfortunately, these insular implementations were likely not compatible with each other and forced developers to lock themselves in with a specific framework for a given project. Today the story is different. The new PHP community uses package management and component libraries to mix and match the best available tools. ... There are also exciting things happening with PHP under the hood, too. The PHP Zend Engine recently introduced memory usage optimizations. The memory usage in PHP 5.5 is far less than earlier versions.'"

An anonymous reader writes "Beyond your smartphone screen lies an infinitely more interesting world, if only you could get past the myopic app view you're currently bound to. Glen Martin ponders the existential unease lying at the root of the Internet of Things: 'We're already cyborgs: biological matrices augmented by wirelessly connected silicon arrays of various configurations. The problem is that we're pretty clunky as cyborgs go. We rely on screens and mobile devices to extend our powers beyond the biological. That leads to everything from atrophying social skills as face-to-face interactions decline to fatal encounters with garbage trucks as we wander, texting and oblivious, into traffic. So, if we're going to be cyborgs, argues Breseman, let's be competent, sophisticated cyborgs. For one thing, it's now in our ability to upgrade beyond the screen. For another, being better cyborgs may make us — paradoxically — more human.'"
