Coding Challenge Wrap-Up: Who Won at Sevens

Dice Coding Challenge Winner Badge
This was the contest I thought would never get started. Although the game Sevens is easy to play, getting the bot-runner code to run the compiled bots proved to be harder that I thought. I solved it for C, C++ and C# easily enough: These are all languages that produced a compiled .exe, but for running Java programs it took a bit longer. Then, when I solved that and started running the contest, it turned out that several of the… continue…

Tournament of Sevens: Week 1 Results

Marathon
Though the Tournament of Sevens coding challenge took much longer to get off the ground than expected, I’ve taken steps to sort out the bot bugginess and the contest is now roaring ahead. The first week included 16 viable competitors, out of 19 entries. One obstacle in getting this going was from Eclipse projects. The problem with them is that their source files end up in different places and the IDE is a bit fiddly building and deploying the class… continue…

StumbleUpon Logo
StumbleUpon has the best of both worlds – the agility of a startup and the stability of a 12-year-old company. At least that’s how its vice president of engineering, Paul Antaki, sees it. The San Francisco-based company offers up Web pages, videos and photos based on subscribers’ self-selected likes and dislikes. It’s powered by a lean but growing crew of approximately 90 people, of which half work in technology. The site relies heavily on Hadoop, R, Raku and Octave, and… continue…

With an estimated 9 million developers using it, Java is one of the most popular programming languages around. In fact, some estimate that Java powers more than 3 billion devices. With so many people claiming expertise, IT managers often ask tricky technical questions to separate the novices from senior developers, says David Bolton, guide of the Dice Java Talent Community. Here are some questions you can expect to hear. What is Type Erasure? What Most People Say: “Umm, I’m not… continue…

Employers Say This is Why You’re Not Getting Hired

Unemployed Worker
It’s a continuing complaint: Employers who need skilled IT professionals say they can’t find people to fill their open jobs. But job seekers say it’s getting harder and harder to find a job. Why the disconnect? The unemployment rate in technology seems to underscore the employers’ arguments that there’s more demand than supply. During the fourth quarter of 2013, the rate dropped to 3.5 percent from 3.9 percent, according to Dice’s Q4 Tech Trends Report. That compares to a national… continue…

Tournament of Sevens Contest Update: A Saga

Tired Runner
I picked the game for this contest with the thought that it would be simple and straight forward. Was I ever wrong! The contest was due to start Jan. 1, but a sudden unexpected vacation took me to Vegas through Jan. 2. With jet lag and such, I wasn’t really up to sorting the entries it for a day or two after. I had most of my competition runner created, though I hadn’t debugged it. By that point, there were… continue…

You hear about it a lot: Employers want job seekers who have the right experience, but you can’t get the experience if someone doesn’t hire you for the right job. In this week’s Dice News Hangout, Sharadon Smith of the Nova Job Center in Sunnyvale, Calif., and Dice Software Engineering Community Guide Catherine Powell look at how both job seekers fresh out of college and those trying to change their career path can break the cycle.

Why Managed Code Is Safer

C# as Machine Code
One of the biggest sea changes in computing took place in the late 1990s, with the switch over to running managed code, first with Java and then a couple of years later with .NET. Prior to this, compiled code (typically written in C, C++, Visual Basic or Delphi/Pascal) produced unmanaged code. Yes, both of these run machine code. So what’s the difference? Unmanaged Code Unmanaged code is just low level code (machine code) that the CPU (Central Processing Unit) executes… continue…
