Constant Comment

According to most, good programming practice never hardwires file names or numeric values into code, but defines them as constants instead. Is this always the best way to go? If you are honestly only going to use a value in one place, doesn't defining it elsewhere just make it harder to figure out, since you have to go searching for wherever you defined that constant? Is SMILEY_FACE_IMAGE_FILE_NAME really better than "smileyface.png"? Let us know on Reddit.

Implementing Hypermedia Clients

Coding hypermedia clients need not be ugly nor complicated. In his top-rated talk from Fluent 2013, Mike Amundsen shows you how to write clean, adaptive code that responds to changes in data and workflow requirements over time. This talk covers the truth (both good and bad) about hypermedia client coding and includes examples of several client models that handle evolvable hypermedia APIs without sacrificing user experience or requiring Herculean effort on the part of developers.

What Our Community Is Talking About

BrainsBrains… Brains…
If you've ever wondered where in the brain programming happens, some new research may help satisfy your curiosity. fMRI studies of programmers thinking about code snippets show activity in the same areas that deal with language processing, more so than the areas responsible for math.

Meet Atom
Github introduced Atom, a new text editor with a unique combination of hackability and usability. Their goal was to create a tool that could be customized to do anything, but was also simple enough to use productively on the first day without ever touching a config file. And as if this wasn't enough of an accomplishment, the entire thing is open source and begging to be hacked on.

Cisco Joins the Open Source Club
The networking giant has released OpenAppID, a tool that lets developers create their own firewall that can identify applications by their network fingerprints.

Have Some Benchmarks
Minimize Server-Side Burden
RackspaceApplication developers want to minimize their server-side burden. As the applications they build become more complex and data-rich, they require extremely fast server-side storage and networking, SSDs, and the flexibility to add new nodes instantly from within their application. Performance servers combined with highly redundant MongoDB with auto-sharding take care of this burden.

When Agile Doesn't Fit
For many projects, short delivery cycles and staying close to shipping make sense. But when you get one shot to get it right, and your customer is shortly going to be light-minutes away, it may not be the best choice. Just ask JPL.

The Human Side of Big Data
Building a Solid World At the Strata conference, much of the focus is usually on grinding data to gain insights, but increasingly the human costs of analytics are starting to become important. This year, there was a serious discussion of how we can ensure that people flourish in the age of the machine.

Building a Solid World
O’Reilly’s Solid examines the new world where software, hardware, and networking intersect. It’s happening all around us right now: robotics, sensor networks, the Internet of Things, the Industrial Internet, the Maker movement, and hardware-oriented startups. Learn more in this free report by Mike Loukides and Jon Bruner.

WiFi Follies
Apple found itself having to issue an emergency patch to iOS this week when an exploit was discovered that would allow for man-in-the-middle attacks against users connecting via WiFi. Evidently, the same problem may exist in OS X, so a patch for the desktop OS may be in the works as well.

The Great Source Control Wars


Last week's question led to another busy Reddit thread.

materialdesigner: "Surprisingly enough I keep hearing about Mercurial now being talked about in the ways Git used to be talked about. I don't personally use hg but with recent high profile moves like Sun and Facebook, I think Git will never be the absolute most dominant."

recursive: "Git seems kind of crappy on Windows, where it seems to require installing some flavor of incomprehensible Unix simulator. That limits its adoption in large enterprise. That and the lack of a graphical client that doesn't require you to occasionally use a command line to unwedge a messed up state."

andyfuu: "It's simple really. I worked at a company that had a HUGE SVN repository with hundreds of products in and probably 100,000 commits. How much effort would it take to migrate that all to Git and assure everything was working well? The amount of work it would take negates the benefits. It's not like SVN is terrible. It can still be used so there's really no point."

Sparserlogic: "We just recently dumped Git internally. The overhead necessary to manage branches was such a burden that we no longer wanted to deal with it. We've gone back to TFS happily now and hopefully will stay there until a nicer versioning tool comes our way."

We recently took note of a handy guide that Google created for early adopters of their Glass augmented reality hardware. The document encourages Glass owners not to be "creepy" or "rude" while using them, although we're not sure that you can wear them and not seem at least a bit creepy as you stare out into your data space while walking into a lamppost.

While dining outIt did, however, make us wish that makers of more traditional mobile technologies would also create etiquette guides for their devices. Here are some suggestions.

  • While dining out, it is never acceptable to play video of your family with the volume turned all the way up.
  • Using your iPad as a camera at a concert is a great way to see just how good that SquareTrade cracked display replacement policy really is.
  • Good idea: Taking a selfie with Vladimir Putin. Bad idea: Taking a selfie with a corpse.

Or maybe, as inappropriate use of mobile technology in public becomes an epidemic, we should look to Coke Labs for the solution.
