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.  

For their 3rd CTF, they've decided to switch gears and focus on distributed systems.  Each of the 5 CTF levels focused on a…

Tokyo Observations: Coin-op Card Games

As a kid I loved playing coin-op games. Some of my favorites were: Space Invaders, Defender, Centipede, Galaxian and Galaga, Dig Dug, Tempest, Joust, Tempest, Spy Hunter, Tron, Robotron, and I must've spent a lot on Gauntlet.

My experiences with them were mostly at where ever I could find them. From…

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. If you've ever done over-the-air distribution of iOS applications, then you have probably seen what happens when you attempt to install an application that is not signed properly. 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…

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…

Bill Spencer Leaves the HVCA

From an email:

"Dear HVCA Members and Friends

Happy Birthday Mac and Are Tablets the Future?

The Mac turned 30 today.  Happy Birthday, Mac!  Apple has been through ups and downs in those 30 years, but now they are one of the most successful companies in the world.  That’s thanks in large part to the success of their iPods, iPhones and iPads, but the Mac remains a mainstay of Apple’s product…

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.

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…

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.
