What evil force, more powerful than Innovation and Progress, is at work here? … I call this force the Tyranny of the Marginal User. … a company with a billion-user product doesn’t actually care about its billion existing users....
The exponential horn of testing · GitHub The actual model that more closely resembles what we need should have the bare minimum of E2E tests, quite a number of service tests and the vast majority should be unit tests. Exponential model: x = 10^hy So if the height h goes from 1 to 2 to 3 then we have 1 E2E test to 100 service tests to 10,000 unit tests....
Your company may not be in the software business, but eventually, a software company will be in your business. — Naval on Twitter

A real story of how following good security practices is both easier to do than ad-hoc methods, and it spreads quickly to others.
Programs must be written for people to read, and only incidentally for machines to execute. Hal Abelson and Gerald Jay Sussman in MIT Structure and Interpretation of Computer Programs course (via Brevity vs. Clarity · An A List Apart Blog Post )
The problem? For example, 3 guys wrote a paper in 86 and they said that a good estimate is an estimate that’s within 25% of the original estimate, 75% of the time … so, mostly one quarter wrong . Yikes, not a very good prospect at all. The gist of #noestimates to determine how much scope can be delivered by a given date: Select the most important piece of work you need to do (highest value first) Break that piece of work down into risk-neutral chunks of work: (…) small enough that failing to deliver it at first attempt will not jeopardize the project [typically ~1 day chunks] Develop (…) Deliver that work to a production-like environment....

The Flipboard Explorer, or FLEX, is a component that you can easily drop into any iOS project. When presented, FLEX shows a debugging toolbar that lives in a window above your app. From this toolbar, you can view and modify nearly every piece of state in the application. Unlike many other debugging tools, FLEX works entirely inside your app, so you donʼt need to be connected to LLDB/Xcode or a different remote debugging server....
The Wilderness It’s a period of time where I’m pretty lost, and I don’t know what to do. I have feature lists, I have open bugs to fix, and I have an outline of where the app is going. But I feel mentally incapacitated, like I’m getting nothing done. I call this “The Wilderness”.

Richard Feynman, the Challenger Disaster, and Software Engineering : Gustavo Duarte With respect to software, I take out four main points: Engineering can only be as good as its relationship with management Big design up front is foolish Software has much in common with other engineering disciplines Reliable systems are built by rigorously tested , incremental bottom-up engineering with an ‘attitude of highest quality’
