Stripe's Capture the Flag 3

A few weeks ago, Stripe hosted their 3rd Capture the Flag competition.  Their first two CTFs were focused on security where you had to exploit a vulnerability in a small system or application to move on to each level until the final level is completed.

How to Lose $150 While You Sleep

Last night I was working on a script to build and sign iOS applications for ad hoc distribution.

The installation will start and progress to a certain point and then fail and then re-try forever or until you interrupt it. What I discovered last night is that even when you interrupt it, it may still continue looping…

SharePoint Online / Office 365 Claims Authentication + Python

Couldn't find any complete references for authentication to SharePoint Online via a non-Microsoft API (surprisingly Microsoft wasn't very helpful, they assume you're using WIF). 

It was pretty trivial once I found this great post explaining how SharePoint Online claims authentication works. 

Remote authentication in SharePoint Online

 

Of course I only found…

Six Sigma Web Servers

Many of you have heard of Six Sigma as a methodology (primarily for large organizations) for quality and process improvement.

Efficient Knowledge Transfer in Social Graphs: Meet the Flying Gurnard

Last week while strolling down the Ala Wai with my 2yo son we stopped to look at the crabs that collect around the stairs that decend into the canal. I was glancing down at my iPhone when my son suddenly yelled "BIRD FISH!" and started pointing. I looked over and saw this:

In the thousands of hours I've spent walking up…

Having Lots of VC Investment Doesn't Boost Startup Activity, Kaufman Finds

Contrary to conventional wisdom, research universities that receive millions of dollars in government grants don't contribute to higher entrepreneurship rates in their hometowns, says a new Kauffman Foundation study, which looked at startup rates in 356 metropolitan areas in the U.S. Having lots of venture capital investment in your market doesn't necessarily boost startup activity either, the study found.

"Policymakers should…

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

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.
