Towards a Smartphone That’s Better for Everyone

Look around you, and just about everyone you see probably has a smartphone. And if those smartphone owners were aware of the sweatshop labor in dangerous conditions and minerals which finance arms-buying,…

Remove and Prevent Download of an Unwanted iOS 7 Update Installer in iOS 6

In perhaps an unfriendly move by Apple, iOS 6 devices that are charging and connected to wifi get the possibly unwanted benefit of receiving the iOS 7 Update Installer that will sit on the device and take up valuable storage space in addition to the continual nagging of a red alert icon. There are some good reasons not to upgrade to iOS 7 on older devices.

  • iOS 7 may not run well on less powerful devices.
  • The new operating system brings changes that may be…

Tokyo Observations: QR Codes

I took a short trip to Tokyo in October to visit family and friends. I've lived there for over eight years, so every time I go back I notice what's changed. And since I'm on the geekier side, I notice tech-related changes.

QR Codes to Search Boxes

When I moved to Tokyo…

Get a Cheap Smartphone

Do you have a smartphone?  Chances are you do.  Whether it is an iPhone, an Android phone or any one of the many other smartphones out there it is clear that the age of the feature phone (dumbphone) is past.  This year, for the first time, smartphone sales have exceeded dumbphone sales worldwide.

The explosion of smartphones is due to the steady march of technology getting better and lowering costs.  Smartphones have dropped in cost from $600+ in the early 2000’s…

Facebook: Grow Up

Note: I write this as a fan and frequent user of Facebook. In addition to helping my family stay connected with friends around the world, the site has helped our company find new customers and team members. I wish them well. That being said, there are many areas where FB really needs to get its act…

Dumping jQuery

 

Dear $,

I think we should talk.

To be perfectly frank, I think we should see other people. I understand that we have a considerable history together, but for me to grow as a developer, I need to be able to see what else…

SQL v. NoSQL Shootout in the Cloud

VERSUS

Ok, ok admittedly it's not really a "shootout". We all already know SQL-based data sources are generally less performant and less scalable than their NoSQL counterparts, but they are also generally more robust and…

Evolving Mobile Technology

Sometimes it seems like there is a new mobile phone or device announced every day.  It’s an exciting time when the things we could only dream about 15 years ago are becoming reality. What do we have to look forward to in the next few years and beyond?



Near Field Communication (NFC)

The technology allows interaction between devices and even unpowered chips or tags.  It’s already used in a…

Social Media: The Rise of Anti-Oversharing Apps

Could it be that we building up to a collective moment against oversharing? That social media posturing, "like"-chasing and follower-building have created a backlash and a hunger for less exposed, more targeted, and more authentic forms of connecting? Perhaps so, judging by the intense interest around apps like SnapChat, Whisper, and Avocado.

Web security for the small-to-medium sized enterprise

There is no doubt that all of us have heard about the security breaches of numerous Fortune 500 companies.  From credit card information hijacks to content defilement, there is no shortage of news reports detailing the exploits of uber-hackers or hacker groups.  The companies that were aggrieved were so, in part, due to their size.  The acclaim for a hacker penetrating Wal-Mart or Citibank will be far greater than that achieved by taking down Joe's Pool & Spa.  But the havoc wreaked on…

<? Personal Home Page ?>

On various occasions in various settings I’ve been asked for my opinion on PHP as a web development platform. It is one of the most popular choices today, yet it is also one of the most criticized by experts. I personally have not touched the language for over a decade but it was once one of my favorite tools.

I remember doing professional web development during the first Internet boom in CGI scripts written with Perl. It was quite cryptic compared to the Java I was learning in school…

Navigating Past a Herd of HiPPOs

HiPPOs -- the Highest Paid Person's Opinions -- are a well-known pitfall and obstacle to creating a great web site or mobile app. Features or designs aren't chosen because they're what users need, but because they're what the HiPPO wants.

Well, another common pitfall is something worse than digital design by HiPPO -- digital design by a herd of HiPPOs. Usually, the powerful heads of several departments all want their desires represented. If they all got their way, the new site or app…

Auto-Updating Enterprise or Ad-Hoc iOS Applications

I work on Enterprise iOS applications for a large energy company and do not have access to an MDM, but I recently had a requirement to provide an in-app way to notify users when an update is available and a way to update it immediately if they choose to. Another requirement was that it must be completely managed within the company's network, so systems like TestFlightApp were not an option.  So I created a custom UpdateManager class that I reference in my AppDelegate as such:…

Be "social" but also show your users you care about their privacy

Recent events like the leaking of PRISM have reinvigorated the concerns of many for their privacy online.  This is a broad subject, and I am by no means a security expert, but I would to talk about an easy way to give a little control back to your users.

It's virtually impossible these days to visit a web page without seeing several social media "share" buttons/widgets.  Making it ridiculously easy for your users to send your page to their favourite social twitbookfacegramsnapspace is…
