Building high quality software in a small team requires thoughtful application of both soft and sharp focus. As primarily a back end or systems engineer, I rely heavily on UI tooling to offload cognitive overhead without sacrificing design quality.

Over the years, I've heard many ways to frame the tradeoff in work conditions that optimize contributors' work productivity and managers' work productivity. The most popular being "Maker schedule, manager schedule." While I agree that some kinds of work are best suited to specific work conditions, I'm unconvinced a manager versus individual contributor framing is helpful when attempting to determine how to structure my workday.

In 2018, I set out to establish habits that made me physically, economically, and mentally healthier. It's been tough, but worth it. And it gets easier every day.
Here's the metrics I've used to guide me, the goals I set to improve those metrics, and where I am now.
Having been with Kiera for going on 4 years now; and having lived together for 3 of those years; It seemed a bit unnecessary that we maintain separate budgets for shared resources like groceries, rent, utilities, streaming media accounts, etc. We’d cobbled together a “I‘ll pay for Blue Apron if you pay for the CSA” form of spreading of fiscal responsibilities, but that was getting more and more complicated and difficult to balance to ensure an equitable split based upon our respective incomes.
About a year ago I got back into freelancing and started building a small, distributed development studio. While I enjoyed the freedom and the people; I couldn't sustain the constant sales cycle and discovered management and operations is a recipe for burnout for me. My constant anxiety over payroll, bookkeeping and cash flow was debilitating.
I could write in depth about what I've learned about myself and running a business over the past year; or describe the agony of laying off good people who may struggle to find new work due to systemic bias; or tipping into depression due to a combination of burnout and the erosion of my self-confidence. But instead I'd like to look forward. It's less painful.
Code review gets a bad rap. People worry that code reviews slow teams down, create conflict between team members, or disempower team members by taking away decision making authority.
I believe these concerns are anti-patterns that indicate a team is using code review for criticism as opposed to critique. What's the difference? Critique is focused on specific parameters, where criticism is unbound.
That said, many programmers are unclear how to perform judgement free code reviews. The following are a series of suggestions which may help move code reviews from criticism to critique:

Well-facilitated, compassionate retrospectives (the practice of taking time to discuss how to improve the effectiveness of a team) are, in my experience, the core differentiator between a gelling, high-performing team and a team that struggles to get things done.
Now that I work primarily on distributed teams, I've found that retrospectives are a touch harder. They lack the high-bandwidth feedback of body language that can tell you early on when someone is getting upset or has something to say but isn't quite ready to say it.

Tests are use cases.
They illustrate how to use the code they're testing.
They provide examples of how the code works in a given context.
They describe the code's behavior.
They highlight pain in how to use the code.
They expose complexity in our code and the business domain.
When they notify us the code no longer behaves as specified? That's a bonus. Not the goal.
When we test, we get critical design feedback.

As bootcamp-esque educational programs train more people on the baseline skills to contribute to a software project, companies are learning how (and how not) to integrate these lower-cost, less experienced developers with their teams. Frequently, these companies hire these less-experienced, single-skilled individuals as "Junior Developers" and throw them at a project.
While this has some level of success, savvy companies are turning to apprenticeship.
Zinc is a recently incorporated business focused on technical team training, end-to-end product development, and technical management consulting.

It's no secret there is a growing demand for technical and creative skills and that our educational system is struggling to provide the skills to deliver useful, working, modern products and services. This is further exacerbated by our industries unwillingness to look beyond a certain archetype.
Companies are beginning to realize what science has told us for years: framing the problem effectively is the best way to encourage others to solve it and are responding by investing more heavily in employee training.

For the past year or so, I've been doing most of my computing at a walking desk. When I tell people this, they immediately ask "But how?!" or confidently declare "I wouldn't be able to walk while working!"
While I was a bit skeptical at first, I find a walking desk fits quite nicely into my work habits. I start the day with a mile or so walk, followed by sitting and/or standing until lunch. After lunch I sit for a while, then switch to walking. On a good day, I walk about eight miles. On average, I tend to walk two to four miles a day.

Once upon a time there was a Chef. This Chef was sought by all of the rulers in the land to cater their feasts. The Chef was ferried from castle to castle; delighting all for whom they cooked.
One day, a pair of scullery workers asked The Chef to tell them the secret. "My children," The Chef replied, "I have no secret. I wake up each day. I plan what I will make. I make it. I review how it went. I learn when things don't go well, and I learn when things do.

We all have different paths along the long road, and it's often difficult to find the best path. We have different goals and different constraints. Some of us want to specialize in consumer-facing mobile apps; others want to rethink the cryptographical underpinnings of our networking protocols, and still others want to write code to provide a safe driving experience for those of us who plummet down the highway in a metal container going 80 miles an hour.
This is OK; there's tons of room for different passions in the technology field.

As programmers, we split our code along what job those bits of code do for us. We pontificate about whether MVVM or MVC or another pattern is the appropriate way to build an app for the given language, environment, or problem domain.
This is valuable! Adaptable code knows little about other parts of the system, and good application design patterns guide us to writing adaptable code with little effort.
I am curious: how does slicing code along the job code does for users impact how we build software?

& is a powerful ruby operator, when you use it as a unary operator it has two main use cases:
The most common is to pass an object as a block to a method, like this:
[1,2,nil, 3].reject(&:nil?)
This calls #to_proc
on the symbol :nil?
, converts the result into a block,
and passes it to the reject method. A line by line breakdown looks something
like this:
