Turn off iMessage link previews in iOS 10+

There is currently no way to turn off link previews in iOS 10.  This “feature” is a half-baked attempt to add slack-like features, where GIFs, YouTube links, pictures, etc show up in-line in your iMessage conversation thread. I really wish Apple would have added a way to turn this off because it slows down the interface on my older iPhone 6, and also presents a security/privacy risk. If I don’t accept the privacy policy of a website, I used to have the choice to not click on the link go to that website.  Further, by going to that site, I reveal all sorts of information including my IP (and possibly even my location). With iOS 10, the messages app does this automatically, whether you wanted to load an image (on cell data) or not.

There is a way that you can turn off this “feature” when you’re sending links to people: Don’t put the link as the first thing in the message… I use the “.” character to disable this on links that I send.   You can (and should) also send a feedback report to Apple asking them to add in a user setting to disable the “feature.”

Cloudification of Things

Cloudbursting, the ability to rent additional servers in the cloud on demand, has been an extremely successful concept in enterprise computing recently. When a researcher has the need to perform complex computations, rather than investing in a supercomputer, she can rent a cluster of Amazon’s idle servers for just the duration of the calculations. She pays for the power when he needs it, and when she doesn’t she avoids having an expensive asset sitting idle and depreciating.

Expansion into the cloud has been made possible in part by improved networking. Analogous to decreased shipping costs, more bandwidth reduces the friction in moving large sets of data from the firm to the cloud. What will enable the Cloudification of Things is the decreased friction in loan logistics.

Take Zipcar, for example. Some people do not need a car 7 days a week. Rather than having a depreciating asset sitting in a car park, Zipcar users can rent a vehicle for only the time which they need. The proliferation of GPS tracking devices has reduced the friction in trusting customers to return a vehicle, allowing this business to be viable.

Another example is fashion site Rent the Runway. Rather than paying for an outfit which is to be worn but a few times, customers can rent these items for a special occasion. Courtesy of improved shipping routes and delivery algorithms, shipping costs have actually decreased while fuel costs increase. Decreased transitional costs combined with large inventory availability has removed the friction that prevented previous clothing rental companies from being successful.

From records, to 8 tracks, to CDs, to iTunes, the music industry has never been complacent with any particular medium. Shifting from iTunes, users begun favoring “rented” music with services like Spotify, Pandora, and iTunes Match.

There are many other examples of users transitioning from ownership to renting, most of which have been enabled by reduced friction in transactional logistics. Going forward, there are many other businesses that have the ability to “cloudify” their business model.

Further, the nature of this model need not be B2C. Consumer-to-consumer rentals can also lead to a more efficient utilization of underutilized assets. Photography equipment, vacation homes, office space, restaurants, energy production equipment, and farming equipment are just a few possibilities.

It’s been estimated that Manhattan was sold by Native Americans to explorers for only $24. The reasoning for the low price was that the Native Americans believe that it was impossible to “own” land. How humanity defines ownership has never been consistent across time and cultures.

“Imagine no possessions,
I wonder if you can.
No need for greed or hunger,
A brotherhood of man.
Imagine all the people, sharing all the world”

– John Lennon, 1971

Interview with Virginia.edu hackers, R00TTH3B0X

I’m surprised to be writing this, but I think the hacking incident this week with the Virginia.edu homepage is terrifically ironic.  Before chatting with the two hackers, who go by the handles “x86” and “n3tcat,”  I thought that the episode could be an important milestone for computer science, and IT in general at the University. I think there are a few takeaways: First, the exploit serves as a reminder that we must never rest assured systems are, and will always be, secure.  Second, improperly managed software can cause problems beyond their foreseeable scope. And finally, a quick response does not always equate to the best response.

I chatted with x86 and n3tcat using an encrypted application called cryptocat, which prevented me from determining their IP addresses, and consequentially, protecting their anonymity.   My purpose for chatting with them was to find out their motives, and to see if they shared the same view on always pushing technology to it’s edge for the purposes of furthering our general security as I did.  I ask them why, if they had access to everything (as they claimed), would they only take down the site’s homepage, leaving everything else in tact.

Pull the Plug on Plug Pulling

Most citizens accept reasonable societal conventions such as separate gender restrooms, wearing clothes in public or driving on the right side of the road. But people who unquestioningly comply with irrational conventions like not wearing white after Labor Day or turning their electronics off during takeoff and landing infuriate me.

Every time I fly, I am reminded of society’s willingness to comply with the status quo when I am forced to pause my music until reaching the magical altitude of 10,000 feet, below which my Kindle would supposedly send aircraft, satellites and the International Space Station spiraling into Armageddon-style oblivion. Having to stop drafting emails from my iPad for a few minutes or put down a good e-book is only a minor hassle; but what bothers me is the bogus reasoning behind why travellers are required to do so.

The reason commonly offered by flight attendants is that the electronics will interfere with “navigational instruments aboard the aircraft.” Most consumer electronics, powered only by a few watts, are required to pass FCC tests guaranteeing that they specifically do not interfere with any other electronics. Furthermore, even “Mythbusters” aired a special about cell phones disrupting aircraft navigation. The result? “Modern planes are well-shielded enough to not be affected.”
