  Android hardware fails more than iPhone, BlackBerry; repairs cost carriers $2 billion

Repairs to Android smartphones cost wireless carriers $2 billion per year according to a new year-long WDS study that tracked 600,000 support calls around the globe. Android’s popularity and the introduction of a number of low-cost smartphones has put a strain on the wireless business model, WDS noted in its report. “Deployment by more than 25 OEMs and lower-cost product coming to market is leading to higher than average rates of hardware failures and, in turn, return and repair cos...

  Python threads: communication and stopping

A very common doubt developers new to Python have is how to use its threads correctly. Specifically, a large amount of questions on StackOverflow show that people struggle most with two aspects: How to stop / kill a threadHow to safely pass data to a thread and back I already have a blog post touching on these issues right here, but I feel it’s too task-specific for sockets, and a more basic and general post would be appropriate. I assume the reader has a basic familiarity with Pytho...

  A Few Lessons I Learned After Having Failed

I’ve missed more than 9000 shots in my career. I’ve lost almost 300 games. 26 times, I’ve been trusted to take the game winning shot and missed. I’ve failed over and over and over again in my life. And that is why I succeed.- Michael JordanIt was mid 2008 and Younique was doing reasonably well. However, I had an itch that I needed to scratch. I wanted to build a mobile advertising platform – think DoubleClickmeets AdMob. At the time the mobile adverti...

  Why I left Google

Ok, I relent. Everyone wants to know why I left and answering individually isn’t scaling so here it is, laid out in its long form. Read a little (I get to the punch line in the 3rd paragraph) or read it all. But a warning in advance: there is no drama here, no tell-all, no former colleagues bashed and nothing more than you couldn’t already surmise from what’s happening in the press these days surrounding Google and its attitudes toward user privacy and software develo...

  Successful Web Design: It’s All About The Details

While the tools are out there for almost anyone to build a website, the most successful designs all share a few characteristics. These sites tend to be organized well, have great content and have all the design details in order. Small parts of your site, from alignment and bolding to contrast and color, can make or break the design. Taking care of the details before your project is published will ensure the page has a clean overall feel. Unorganized design and lack of attention to detail ...

  Stop Making Apps

There are a bunch of iPhone apps I own though I have no clue what they do. These apps include but aren’t limited to; FLUD, Apptitude, Cartoonatic, Can’t Wait!, Punch, Pah, Prize Claw, Traveler, Concur, Jajah, Fast Customer, Pimple Popper and many more whose names I can’t even remember.Occupying my valuable homescreen real estate are also a bunch of apps whose purpose I remember only because they were built by people I know or am friends with, but that I sadly never use. And ...

  Management Myth #1: The Myth of 100% Utilization

A manager took me aside at a recent engagement. “You know, Johanna, there’s something I just don’t understand about this agile thing. It sure doesn’t look like everyone is being used at 100 percent.”“And what if they aren’t being used at 100 percent? Is that a problem for you?”“Heck, yes. I’m paying their salaries! I want to know I’m getting their full value for what I’m paying them!”“What if I told you...

  Understand JavaScript prototype

For an front end programming language like JavaScript, if we want to understand its OOP feature, we need to understand its objects, prototype chain, execution context, closure and this keyword in deep. If you have a good understanding on these concepts, you should be confident that you can handle this language well. The inheritance in JavaScript is not class inheritance like Java, but it adopts another mechanism-- prototype inheritance. The key to prototype inheritance is the prototype chain mec...

  SkipList in Go

Algorithmic thinking is the must-have in the coding world, so I have been keeping the routine of algorithm practice every week, consolidating my knowledge of data structures on one hand, and improving my coding skills as well. A difficult one happened to be stuck in my mind- Implement SkipList with Go, which took me quite a weekend. Below is the front-line report of how I finally got the hang of it. First, from its concept. Wiki has explained it well. a skip list is a probab...

  What’s Your Start-up’s “Bus Count”? 7 Myths of Entrepreneurship and Programming

Software development is a rapidly evolving field that got off to a very rocky start. Conventional wisdom for many years was that software engineering should be like other types of engineering: design carefully, specify precisely, and then just build it – exactly to spec. Just like building a bridge, right? The problem with this approach is that software is just that. Soft. It’s endlessly malleable. You can change software pretty much any time you want, and people do. A...
