“As a user” needs to stop. Argues against cargo cult user stories:

The purpose of user stories is to create empathy. As a result, tiny implementation details do not need to be written in the form of user stories. The design and engineering teams can figure that out; that’s their job.

When user stories really shine, they tell a story about the person using your product. The person becomes the hero. You’re just there to create the conditions for her to achieve her real-life goals.

The world in which IPv6 was a good design Or, why is IPv6 such a mess, and how did we get here?

At that point, all we'd have to do is eliminate all remaining UDP and TCP from the Internet, and then we would definitely not need layer 2 bridging anymore, for real this time, and then we could get rid of broadcasts and MAC addresses and SDN and DHCP and all that stuff.

And then the Internet would be elegant again.

There’s a joke in computer science that one of the hardest tasks is naming things in code. It’s funny because it’s a nontechnical task. But it involves something that can be even harder than technical work: communicating with other people and intuiting what they might need and understand.

Surfacing Hidden Change to Pull Requests That's smart! From looking at the code, you can't always tell the side effects of a Pull Request, so why not have CI explain it to you:

In every CI build, we calculate interesting pieces of data like the binary size and method count (an important metric for Android apps) and write them to shared storage. When a CI build runs for a pull request, we figure out the difference of these values from the ancestor commit on master. The numbers are sent back to the pull request in the form of a comment to ensure the author and any reviewers are notified.

What my bathroom window taught me about code quality Pragmatic always wins:

Usually, bad code is expensive. Bad code is hard to understand. Bad code is hard to debug. Bad code is hard to extend. Because of all of these reasons, bad code also decreases the value that can be delivered in the future.

But sometimes, just sometimes, you know you are writing code that will never again be read, and will never be modified. You know it will be used, maybe just once or twice, and then it will be thrown away. That is when bad code is cheap.

How the Imagined “Rationality” of Engineering Is Hurting Diversity — and Engineering For context, in case you missed the Google memo kerfuffle.

So, about this Googler’s manifesto 💯

Essentially, engineering is all about cooperation, collaboration, and empathy for both your colleagues and your customers. If someone told you that engineering was a field where you could get away with not dealing with people or feelings, then I’m very sorry to tell you that you have been lied to. Solitary work is something that only happens at the most junior levels, and even then it’s only possible because someone senior to you — most likely your manager — has been putting in long hours to build up the social structures in your group that let you focus on code.

Dr. NerdLove The Google memo doesn't affect all people equally, to some it's just a point they can afford to debate:

But hey. It’s easy to pretend everything is neutral when it doesn’t touch you AND you strip away all context and history AND consequence.

Why Composition is Harder with Classes I can think of better reasons to avoid inheritance than edge cases of instanceof. Quite often, classes are indeed an implementation detail that should be abstracted behind a factory:

Avoid exporting your class. Use class internally for performance gains, but export a factory that creates instances in order to discourage users from extending your class and avoid forcing callers to use new.

  • Node.js is a key part of the survey user’s toolkit, being used at least half of their development time.

Crack The WIP (Work In Progress) Why it's so hard for teams to limit WIP:

The reality is that low-drama “flow” doesn’t look like progress to most people. There aren’t the burnouts and the tantrums. Supporting casts have less to do, less to coordinate, and less to “unblock”. You run the terrible risk of having someone idle for a bit (god forbid the code editor is closed). Or of having to shuffle people around to tame the real blockers and bottlenecks (with all the politically intrigue that entails).

A hacker stole $31M of Ether — how it happened, and what it means for Ethereum Another day, another coin heist. But this one is different because:

Having sounded the alarm bells, a group of benevolent white-hat hackers from the Ethereum community rapidly organized. They analyzed the attack and realized that there was no way to reverse the thefts, yet many more wallets were vulnerable. Time was of the essence, so they saw only one available option: hack the remaining wallets before the attacker did.

Underhanded Solidity Coding Contest Solidity is the programming language for Ethereum contracts. Ethereum is the next big financial technology since Bitcoin (great overview of Ethereum, Blockchain and friends). As I'm writing this, one Ethereum coin is worth $224 dollars. Anyway, back to Solidity:

There is no garbage collector. Dead allocations are never reclaimed, despite the scarcity of available memory space. There is also no manual memory management.

The compiler is riddled with mis-compilation bugs, many of them security critical. The documentation helpfully includes a list of these bugs .... in JSON.

In some situations, the optimizer replaces certain numbers in the code with routines that compute different numbers
