An Upper Limit For Apps? New Data Suggests Consumers Only Use Around Two Dozen Apps Per Month There are now well over a million mobile applications in both Google Play and the iTunes App Store alike, and growth of those app marketplaces shows no sign of slowing down. However, according to new data from Nielsen out this morning, there may be an upper limit to how many apps people will interact with over the course of a month, and that number – just over a couple dozen – hasn’t grown much over the past few years. That’s good news for the everyday must-have’s, like Facebook, Google, or the default email, messaging, maps or weather applications, for example. But it’s bad news for the young companies trying to establish a foothold and core group of dedicated, engaged and loyal users within the ever-expanding app universe. According to Nielsen, U.S. iPhone and Android users over 18 have been increasing the time they spend using mobile applications, which is up 65% over just two years ago.

GM recalls 26,582 Buick Lacrosses, Cadillac SRXs for software problem GM recalls 26,582 Buick Lacrosses, Cadillac SRXs for software problem General Motors is recalling 26,582 model year 2013 Cadillac SRX crossovers and Buick LaCrosse sedans to fix a software problem that could allow the vehicles' transmissions to slip suddenly from manual to automatic mode. Information posted on the National Highway Traffic Safety Administration website said that the software problem may cause the transmissions to inadvertently shift to sport mode, removing any transmission-related engine braking effect. The NHTSA said that the risks of a crash are increased if engine braking is unexpectedly removed. GM said in a statement that the issue was discovered on a 2014 engineering development vehicle. The company hasn't received any complaints about the problem, it said, adding that it has no reports of crashes or injuries related to the problem. GM said dealers will reprogram the transmission control module for free. The LaCrosses were manufactured between April 25, 2012, through March 6.

Web analytics tools are abundant, but in order to use such tools effectively, you need to decide what information you need and how to interpret it correctly. After that you then need to make the necessary changes to your web site in order to attract more visitors and improve your search engine rankings. What information do I need? This is a question that you should try answering before deciding on which web analytics tool to choose – going for the most advanced and most expensive one is not always the best choice. Which keywords and key phrases are the visitors using to find your web site? If you want to analyze the on-site experience of your visitors, then you need to look into different data: What are the most popular entry and exit pages? If you decide to run PPC campaigns, then you would need entirely different information, which will help you analyze the success of your campaigns, tune up your ads, and ultimately achieve better return on your investment. What changes should I make? Interpreting Web Analytics for Beginners Interpreting Web Analytics for Beginners
Law of mass action Law of mass action In chemistry, the law of mass action is a mathematical model that explains and predicts behaviours of solutions in dynamic equilibrium. Two aspects are involved in the initial formulation of the law: 1) the equilibrium aspect, concerning the composition of a reaction mixture at equilibrium and 2) the kinetic aspect concerning the rate equations for elementary reactions. Both aspects stem from the research by Cato M. Guldberg and Peter Waage between 1864 and 1879 in which equilibrium constants were derived by using kinetic data and the rate equation which they had proposed. The law is a statement about equilibrium and gives an expression for the equilibrium constant, a quantity characterizing chemical equilibrium. History[edit] In 1877 van 't Hoff independently came to similar conclusions,[6] but was unaware of the earlier work, which prompted Guldberg and Waage to give a fuller and further developed account of their work, in German, in 1879.[7] Van 't Hoff then accepted their priority.
Peter Diamandis Peter Diamandis This might be a controversial blog. My Thanksgiving was one filled with texting, Snapchat, Skyping, Facetime, Beam robots and ringing phones. Some people HATE the way technology impacts their family at gatherings – people on digital devices rather than having conversations – 'making us more alone, even when we're together.' But is that really true? This blog is about perspective on the impact of digital devices, and the bigger picture on what's going on: an accelerating trend where our connection with people is independent of our physical location. We've ALWAYS said that new technology isolates us Source: xkcd.com/1601 "Back in my day, we didn't have all these distractions" – Millions of disgruntled grandparents around the world. "Yeah, in your day, life was pretty boring and disconnected." – Millions of millennials today. We've always preferred to get what we want, when we want. And that trend is accelerating. The fact is we tend to romanticize the past. The Upside of Technology Join Me P.S.

The personalized web is just an interest graph away — Tech News and Analysi The personalized web is just an interest graph away — Tech News and Analysi You know how our social graphs are creeping into every aspect of our web lives, from search results to coupons? Well, get ready for something a lot more personal, a lot more targeted and, perhaps, a lot more creepy. Much as social graphs are maps of our social media connections that follow us across the web, interest graphs are maps of our interests. Some companies want them to follow us across the web, too, meaning that wherever we go, there we are. There’ll be no more need to search through news sites for the stories we want, or shopping sites for the products we want, because the site will know as soon as we hit its system who we are and what we like. Whether you’re fascinated or appalled by the idea of interest graphs, here’s a taste of how they might work. 1. I recently discussed the idea of interest graphs with Gravity CTO Jim Benedetto, who described how his company determines visitors’ interests so its content-industry customers can deliver personalized experiences. 2. 3.

Digital Audio or Audio/Visual is one of those areas that crosses the border between pure technical knowledge about computer'ish subjects - file formats, bit rates, sampling and all that good solid stuff. But it also moves into other territory to do with sound frequencies and if the material is musical - tempo and pitch and harmonics and...and .... and the maths - oof! Fast Fourier Transforms (we had assumed Fast Fourier was a foreign relative of Fast Eddy up until this point) and RMS and Logarithms - stuff we thought we had long, and mercifully, left behind. We were quite shocked on our first excursion into the depths of this dark and frequently secretive world. And the shock when we discovered that you had to pay for some specifications. Health Warning: These pages are a work in progress and are intended to capture our (very) slowly growing knowledge. Contents History: The project is partly professional, partly hobby.

Techbrats Goldberg, Shih and Gopman do not represent the tech industry | Pa By Jason Calacanis On January 5, 2014 In 20 or 30 years, what will we look back on and say “That was the issue of our time?” I ask hyper-intelligent people this question from time to time, and the answers are frequently similar: environment, equality, employment, and wage disparity are common. I believe employment and wage disparity are the critical issues of our time. Nowhere can this be seen more clearly and glaringly than in San Francisco. It’s hard for people not to hate technologists when faced with the absolute loathsomeness of three now-infamous industry executives: Peter Shih, Greg Gopman, and Bryan Goldberg. In three separate blog posts over the past year, these spoiled techbrats have shown the absolute worst qualities of the elite: a lack of empathy and class, combined with horrible entitlement — and the absolute inability to write. His bile was followed by Gopman’s post which claimed: Where to begin? Third, if you have been delightfully rewarded for building websites — websites!!
Larry Page, Google co-founder and CEO, speaks at the Google I/O developers conference in San Francisco. Photograph: Justin Sullivan/Getty Images The Google co-founder Larry Page spoke out on Wednesday about the "negativity" he believes is holding back the technology industry, a day after revealing that he has been suffering from a rare vocal-cord condition that has made it difficult for him to speak. In a raspy voice, Page told the audience at the internet giant's annual developers conference, Google I/O , that he believed a lack of cooperation between tech partners was holding back progress. "Today we are still just scratching the surface of what's possible," he told the conference in San Francisco . Page blamed a "focus on negativity and zero-sum games" for the industry's failure to achieve its full potential. Computers were slow, the web was not advancing as fast as it should be and big technology companies were not co-operating enough, he said.

By Cale Guthrie Weissman On August 26, 2013 About a week ago a thread on Reddit appeared aiming to set the world straight about the ways of the world. The thread was entitled, “What is a ‘dirty little (or big) secret’ about an industry that you have worked in, that people outside the industry really ought to know?” And, with the vitriol the world has begun to know and expect from Reddit, the truth behind myriad industries was laid bare. Any tech take-homes from the 35,000+ responses? Well, IT, customer service, and software development in general all appear to be a huge mess. Enjoy. Perhaps the most obvious: startup life is crazy! Work for tech startups! One startup in particular is mentioned, Kickstarter: You know those celebrity endorsements in Kickstarter vids? Here’s an interesting one about ISPs, bandwidth-use, and content providers: What really makes me angry is how some ISPs are expecting to get paid by three different parties to deliver certain traffic (read: Netflix and Youtube).
