Not all heroes wear capes. Some, like Leontien Talboom, rock bangs and suspenders while playing a real-life game of Operation on old floppy disks to preserve their content. When Talboom was a kid, she used floppy disks to save her fictional stories about Furbys, the popular robotic toy of the 90s, which she would write on her father’s old work laptop.
Today, Talboom, who is now a Cambridge University Library technical analyst, spends her time preserving knowledge about floppies while rescuing content from them as part of the library’s Future Nostalgia project. Why is Future Nostalgia’s work so important? There is limited time to image floppy disks (i.e., duplicate the data on them) because their material can degrade and oxidize over time.
“A lot of the ones that we have in our collection are dating from the ’70s, ’80s, ’90s,” Talboom said. “So, we’re talking at least 30 years by, even getting very close to 50 years for some of them.”

Have you ever been tempted to spend less than $1,000 on satellite equipment—just so you can show how much sensitive data can be easily accessed?
Computer scientists from the University of California, San Diego, and the University of Maryland answered “yes” to that question. In a research paper published Oct. 13, they wrote that they can use satellites to access large amounts of sensitive and unencrypted traffic from a variety of sectors, including the telecommunication, retail, and even the military.
The setup. The researchers focused their study on geostationary (GEO) satellites, which orbit the Earth’s equator, receiving and amplifying signals from the ground. Hardware used to conduct the study included a Ku-Band satellite dish, a low-noise block downconverter to amplify weak signals, and a dish motor to enable automated movement for tracking purposes, among other materials. In total, the equipment ran the researchers just under $700, or roughly what you’d pay to rent a one-bedroom apartment in Wichita, Kansas.

Hackers rollerbladed into theaters almost exactly 30 years ago. The 1995 movie features young, fashionable, rebellious techies (Jonny Lee Miller, Angelina Jolie, Matthew Lillard, and others) as they go up against a corrupt security officer (Fisher Stevens) framing them for an oil-tanker cyberattack.
Nathan Hunstable remembers watching Hackers shortly after its release, when he was a young teenager who had “zero interest in computers.” Now CISO at CEC Entertainment, owner of Chuck E. Cheese, Hunstable’s interest in computers has upped a bit.
We asked the CISO (who began his IT career as a movie-theater network admin) a simple question with a complex answer: How does Hackers—and its many hacks—hold up? Get your popcorn ready. Some security threats—like social engineering—never die.

Everybody knows that tech's top figures, such as Google CEO Larry Page or Facebook co-founder Mark Zuckerberg, are worth billions of dollars thanks to stock options. But how much do everyday tech executives — the CIOs, Chief Data Officers, and so on — earn? Generally between $150,000 and $175,000, not counting possible perks such as stock options, according to a new analysis. That's based on national data, although anyone who works in tech knows that, in high-demand areas such as Silicon Valley, salaries can skyrocket far higher for those with highly specialized skillsets and the right mix of experience. It's a good time to be a Pointy-Haired Boss... but then again, when isn't it?

Average technology salaries in the U.S. saw the biggest year-over-year leap ever, up 7.7 percent to $96,370 annually, according to Dice's new survey data. Bonuses and contract rates also rose from 2014, and tech salaries in seven metro areas reached six-figures for the first time since the survey began more than a decade ago. Contract workers saw a rise (5%) in hourly compensation, with contractors earning $70.26 per hour. Other Websites have shown similarly high salaries for tech professionals; Glassdoor, for example, called data scientist the best job in America, with an average salary of $116,840 and bountiful job prospects. But while everything might seem great on a macro level, that doesn't mean tech workers don't face their share of stagnant salaries, brutal workplaces, and annoying managers.

For years, security experts have told people they need better passwords protecting their online accounts: no more '123456' or 'qwerty' or 'password.' Based on SplashData’s fifth annual list of the 25 most common passwords, however, it’s clear that relatively few people are listening to that advice (Dice link). The firm based its list on more than 2 million leaked passwords during the year. The most popular, as in 2014, was '123456,' followed by 'password' and the ingenious, uncrackable '12345678.' One new entry on this ignoble list: 'starwars' in 25th place, no doubt thanks in part to the popularity of 'The Force Awakens' and the accompanying marketing campaign. Seems like a lot of people have forgotten (or never learned) that, while it’s a pain to create (much less remember) a complicated password with lots of numbers and special characters, it’s nothing compared to the pain of having your online accounts compromised. Maybe, as some have proposed, we could someday kill passwords for most services.

Technical debt arises for many reasons—whether moving goal posts, pressure to get code tested and released, high programmer turnover, and lack of documentation. Over time, it can also render code a spaghetti-like mess. But how to deal with it? In a new column on Dice, (Dice link) developer David Bolton offers some suggestions, ranging from refactoring to using compiler inference to increase readability and shorten declarations. While those techniques are straightforward, it's clear that a lot of developers let their code get out of control, and trying to plan beforehand doesn't necessarily prevent the work from getting overcomplicated. It seems like every developer has a go-to technique (or four) for keeping things a little more streamlined. What are yours?

Despite some concerns over the stock market and whether the so-called “unicorns” will survive the year, it’s apparently still a good time to get into tech: New data from Robert Half Technology suggests that salaries for various tech positions will increase as much as 7 percent this year. Which is good, because tech professionals have confessed to a host of aggravations with their lives (Dice link), including too-expensive housing, lengthy commutes and gridlock, inability to achieve work-life balance, and a disconnect from their jobs. It’s neither the best nor worst of times, but the money could be pretty good.

What was the most popular programming language of 2015? According to the people behind the TIOBE Index, Java took that coveted spot, winning out over C, Python, PHP, and other languages. “At first sight, it might seem surprising that an old language like Java wins this award,” read TIOBE’s note accompanying the list. “Especially if you take into consideration that Java won the same award exactly 10 years ago.” Yet Java remains essential not only for businesses, it continued, but also consumer-centric markets such as mobile development (i.e., Google Android). That being said, even big languages can tumble. (Dice link) Objective-C tumbled from third place to 18th in the past 12 months, thanks to Apple’s decision to replace it with Swift. In 2016, TIOBE expects that “Java, PHP (with the new 7 release), JavaScript and Swift will be the top 10 winners for 2016. Scala might gain a permanent top 20 position, whereas Rust, Clojure, Julia and TypeScript will also move up considerably in the chart.”

Ford and Chinese technology company DJI (which manufactures drones that specialize in aerial photography) used the spotlight of this year’s CES to announce a developer challenge: figure out how someone in a Ford vehicle can use the dashboard touch-screen to launch (and land) a drone from the back of a pickup. While the challenge is framed as a “search-and-rescue system for the future,” drone control from a moving vehicle has a lot more applications than search-and-rescue. In 2014, Renault designed a concept car that came with a small flying drone controllable via tablet or preset GPS waypoints. In theory, this “flying companion,” launched from a retractable hatch in the roof, could prove especially useful at scanning the road ahead for possible traffic jams. (Renault hasn’t yet announced a production model of the car.) So are drones-from-cars an odd sideshow? Maybe. But if they catch on, imagine the driver-distraction issues from trying to pilot a UAV while you're on the road.

David Foote, an analyst who accurately predicted the tech industry's job growth in 2015, is back with some new predictions about which segments will do well in 2016 (Dice link). At the top of his list: DevOps, cloud and software architects, and cybersecurity experts. Those that won't perform well? SAP specialists, storage 'gurus,' and network managers could all face some headwinds. 'Companies are continuing to outsource infrastructure and that will reduce the need for network specialists except for network security which will remain in-house,' he says. Whether or not he's right about which parts of the tech industry will do better than others, there are also increasing signs that things could get very tight from a funding perspective for startups, as even the so-called 'unicorns' risk seeing investor money (and customers) dry up.

New data from research firm Nielsen shows that — surprise, surprise — Facebook, Google, and Apple dominated the list of most-used mobile apps (Dice link). Facebook’s core app took the top spot on Nielsen’s list with 126 million unique users per month, followed by YouTube with 97 million, Facebook Messenger with 96 million, and Google Search with 95 million. This is partially a consequence of the mobile world essentially becoming a duopoly between Google Android and Apple’s iOS, meaning that the core apps produced by those companies are always front-and-center (and thus always in use) for the majority of mobile users. But not every app launched by these companies succeeds: While Facebook dominates, for example, the company is notable for some app misfires, including Paper and Facebook Home. That might be cold consolation to indie app developers trying to build up a significant audience.

Former CEO Steve Ballmer once publicly referred to Linux as a 'cancer.' Not content to just let Ballmer blow up about it, company also spent a good deal of money and legal effort on claiming that open-source software violated its patents. A decade ago, the idea of Microsoft creating a Linux certification would have seemed like lunacy. But now that very thing has come to pass, (Dice link) with the Microsoft Certified Solutions Associate (MCSA) Linux on Azure certification, designed in conjunction with the Linux Foundation. Earning the Linux on Azure certification requires tech pros to pass Microsoft Exam 70-533 (Implementing Microsoft Azure Infrastructure Solutions) as well as the Linux Foundation Certified System Administrator (LFCS) exam, which collectively require knowledge of Linux and Azure implementation. Microsoft evidently recognizes that open-source technology increasingly powers the cloud and mobile, and that it needs to play nice with the open-source community if it wants to survive and evolve.

The idea with Clang, a compiler front-end for C, C++, Objective-C++, and Objective-C, and LLVM (a compiler infrastructure) is that you can mix the compiler front-end with a targeted back-end and end up with highly portable and efficient compiler. Clang can perform static analysis of your code, and lets you write tools that give you information about a program. Although many developers prefer developing in C/C++ using GCC, developer David Bolton (in a new Dice article) makes an argument for why you should switch to Clang. While GCC is probably still best when it comes to speed, he argues, Clang is improving release by release, and features tools that developers could find useful.

PostgreSQL, MySQL, and MariaDB are the three “main” open-source relational databases available today (there are four if you count FireBird, but for brevity we're excluding it). For years, MySQL had a reputation of being faster than PostgreSQL, but much of that was due to the MyISAM database engine, which didn’t support transactions. On the flip side of things, PostgreSQL had a reputation for being slower but more reliable. But with the recent versions of both platforms, things have started to change; for example, speed has been less of a problem for PostgreSQL, while MySQL now defaults to the InnoDB engine, which does handle transactions. According to developer David Bolton, here's why PostgreSQL is worth a second look for your database-management needs (Dice link).
