Airmail Adds Subscription for Push Notifications

Joe Rossignol (tweet, Reddit):

Airmail for iOS is now free to download on the App Store, but push notifications and multi-account support have become premium features priced at $2.99 per month or $9.99 per year in the United States. The app was previously available for a one-time, upfront cost of $4.99 with all features unlocked.

Speaking of changing the price for features already shipped…

At face value, the change appears to violate Apple’s App Store Review Guidelines, which state “if you are changing your existing app to a subscription-based business model, you should not take away the primary functionality existing users have already paid for.”

Leonardo Chiantini:

Customers who purchased the app can still have access to multiple accounts but not push notifications which, is a side service of the app and is not preventing the use of the app’s core functionality.

We do understand users frustration, the decision was made to keep the business sustainable as we face increasing backend service expenses.

What happens when you ask your paid users to pay again, by changing the monetization model.

Brutal :( for Airmailer. I feel for them, it’s not easy.

Fernando Corbató, RIP

Katie Hafner (via Rodney Brooks):

Dr. Corbató, who spent his entire career at M.I.T., oversaw a project in the early 1960s called the Compatible Time-Sharing System, or C.T.S.S., which allowed multiple users in different locations to access a single computer simultaneously through telephone lines.


C.T.S.S. gave rise to a successor project called Multics, which Dr. Corbató also led. He told the Babbage Institute, “Multics started out as kind of a wish list of what we would like to see in a big computer system that might be made as a commercial model.”

Multics was a collaboration among M.I.T., AT&T’s Bell Laboratories and General Electric. It failed as a commercial endeavor, but it inspired a team of computer scientists at Bell Labs to create Unix, a computer operating system that took root in the 1970s and was adopted widely in the ′80s and ′90s.


In the course of refining time-sharing systems in the 1960s, Dr. Corbató came up with another novelty: the computer password.

Shape Up

Ryan Singer (Ryan Singer):

This book is a guide to how we do product development at Basecamp. It’s also a toolbox full of techniques that you can apply in your own way to your own process.


First, we work in six-week cycles. Six weeks is long enough to build something meaningful start-to-finish and short enough that everyone can feel the deadline looming from the start, so they use the time wisely.


Second, we shape the work before giving it to a team. A small senior group works in parallel to the cycle teams. They define the key elements of a solution before we consider a project ready to bet on. Projects are defined at the right level of abstraction: concrete enough that the teams know what to do, yet abstract enough that they have room to work out the interesting details themselves.


Third, we give full responsibility to a small integrated team of designers and programmers. They define their own tasks, make adjustments to the scope, and work together to build vertical slices of the product one at a time. This is completely different from other methodologies, where managers chop up the work and programmers act like ticket-takers.


This book is about the risk of getting stuck, the risk of getting bogged down with last quarter’s work, wasting time on unexpected problems, and not being free to do what you want to do tomorrow.

Infinite Night Shift

Austin Johnsen (via Ashley Bischoff):

TIL that if you go North of the Arctic Circle in the summer and bring a MacBook with Night Shift set to be triggered by sunrise/sunset, the process will go into an infinite loop because the sun never sets...

I noticed this when my computer fan went crazy because my CPU was running at 120% trying to calculate when sunset was in order to trigger Night Shift. As soon as I turned Night Shift off, that process disappeared and the fan spun back down...
